Terms of Use | zenture

General Terms and Conditions

Proposed effective date: 7 October 2026.

§ 1 Scope, definitions and operator

1.1 zenture UG (haftungsbeschränkt) (“zenture”, “we”) operates the platform at zenture.app. The service includes Chat and other AI-assisted functions and zenture's own processing and examination of submitted work through zenture Runs. External AI model providers are used for the respective requested Chat functionality; Runs are executed within zenture-operated processing.

1.2 Separately validly agreed conditions for specific services apply additionally; individual agreements have statutory precedence. These Terms govern access to and use of the offered web, mobile, API, MCP and client functions. The functions, access methods and plans offered are described in the relevant product description. Agreement to these Terms, acknowledgement of the Privacy Notice, connection authorisation and optional consent are distinct. Agreement to these Terms does not replace separate authorisation for general Learning or optional analytics.

1.3 Consumers are users within § 13 of the German Civil Code (BGB); business customers are users within § 14 BGB. Membership of an organisation does not, by itself, determine legal status. Unless expressly differentiated, provisions apply to both groups.

1.4 Changes

1.4.1 Changes to these Terms are generally announced at least 30 days before their proposed effective date by email or platform notice. Shorter periods may apply where legally required or necessary for security, fraud or abuse measures. Purely beneficial or editorial changes are communicated appropriately. These exceptions do not remove mandatory information, agreement or termination rights.

1.4.2 A change is classified by its effect on the agreed service. Minor developments may include UI adjustments, bug fixes, additional optional features and replacement of a Chat model version while preserving agreed functionality. New offers or prices applying exclusively to new purchases or new subscribers do not by themselves change existing users’ agreed conditions.

1.4.3 Material changes may include higher prices for existing subscriptions, consumption-model changes reducing agreed usage opportunities, removal of agreed core features, new restrictions on existing plans or changes to the validity of allocated Credits. The notice describes affected services and conditions, timing and applicable rights. Permanent platform closure or inability to provide the agreed service is treated separately from a temporary disruption; §§ 8 and 9 apply.

1.4.4 Changes requiring a new agreement are not accepted merely by silence or continued use. The revised version is presented for express acceptance through the designated versioned confirmation flow. New users accept their applicable version at registration; existing users confirm the revised version at the next designated interaction. This flow does not replace any separately required price agreement or optional consent.

1.4.5 Without a valid basis for change, existing contractual conditions remain applicable. Acceptance that has not been given is not retrospectively recorded as given. Possible termination of the previous contract follows § 8.7 and statutory requirements; refusal alone does not forfeit existing entitlements. Statutory requirements for changes to digital services, including information and termination rights, remain unaffected.

1.4.6 Previously acquired contractual entitlements, including Credit purchases, buyback promises, subscriptions, agreed notice periods or export rights, remain preserved. New conditions do not apply retrospectively to already accepted Runs or completed transactions. An informational notice or confirmation of a new version does not blanket-cancel these entitlements.

1.5 Definitions

“Account” means a personal registered user account; it exists independently of a subscription. Guest access is offered only within its described scope and is not equivalent to a personal Account.

“Service” means the platform and its offered web, mobile, API, MCP and client functions. Separately agreed conditions for specific services remain applicable; individual agreements take precedence under applicable law.

“Run” means an AI-assisted examination of submitted work against the task, requirements and evidence considered in that Run. Fast, Standard and Detailed are the Run profiles described in the price list.

“Connection” means a particular client’s permission to use zenture within the described scope. A Connection is not blanket authority for arbitrary actions or data and does not automatically order a Run.

“Credits” are technical usage units under § 4. “Purchased Credits” correspond to purchased; “Promotional Credits” to promotional; and “Subscription Bonus Credits” to subscription_bonus. Their allocation basis, validity and consumption order differ under § 4.2.

“Price list” means the pricing and consumption conditions at zenture.app/pricing in the version applicable to the respective offer or use. It describes Credit purchase prices, subscription prices and allocations, consumption conditions, Run minimum consumption and applicable plan factors. Changes to existing conditions follow § 1.4 and § 4.7.

“Subscription” means a recurring plan with the described services, allocations and consumption conditions. Cancelling a subscription is not closing an Account. “Legacy plan” means a plan closed to new subscribers which continues for existing subscribers under § 8.8.

“Seat” is a user place within an organisation. Authorised organisation administrators manage the designated membership, Seat, shared Credit-pool and billing functions. Funding a Run does not by itself grant access to its complete content.

“Third-party model provider” means an independent provider of an AI model used for Chat functions. “Learning” refers exclusively to the planned features in § 2.9; it is not the ordinary execution of a Run.

§ 2 Service description, access and planned Learning

2.1 zenture provides functions for creating, using and examining content. A Run examines submitted work against the task, requirements and evidence considered in the Run and presents results concerning findings, coverage, limitations and remaining verification needs. Supported functions and access methods depend on the product description and applicable plan. Runs may be processed after a delay depending on available capacity. The examination depends on the submitted content and accessible sources; a result may indicate insufficient evidence or a need for further human review.

2.2 Run results are AI-assisted assessments within the described examination scope. They may be incomplete or incorrect and do not guarantee factual correctness, completeness or suitability for a particular purpose. Results do not replace legal, medical, financial or other professional advice. Users must assess and verify results appropriately for their intended use. This does not exclude the agreed service or statutory rights; liability is governed by § 7.

2.3 Chat models and model availability

2.3.1 Different external AI models may be offered for Chat functions. Supported functions, plans and any agreed model categories follow the respective offer. Access to a function does not mean that using it is free of Credit consumption. External Chat processing is distinct from zenture’s own Run processing.

2.3.2 A particular model version or provider is not permanently guaranteed unless separately agreed. Individual models may be updated, replaced or removed where agreed functionality is preserved and mandatory user rights are respected. A version change is not automatically the discontinuation of an agreed core function.

2.3.3 Where an agreed function or model category is permanently removed without a suitable replacement or materially restricted, § 1.4 applies. Affected functions, available alternatives, effective timing and rights are communicated appropriately. Where possible and reasonable, we seek a functionally comparable replacement. Conditions of a new offer do not retrospectively override existing agreed service commitments.

2.3.4 Previously agreed special model-category, provider-count or notice rights remain preserved. An outage or decision of an external provider does not blanket-remove responsibility for zenture’s own agreed service. Disruption and liability follow §§ 3, 7 and 9; required changes follow § 1.4.

2.4 Users must provide accurate information, keep credentials confidential and promptly report unauthorised access. Guest access, API access and authorised client Connections exist only within the offered and permitted scope. Guest access does not mean that no identifiers or data are processed.

2.5 Authorising a Connection does not, by itself, start a paid Run or create a payment obligation. Later authorised actions are subject to applicable settings, permissions, quotas and pricing terms. The requesting application and permitted actions are described when connecting. Locally deleting credentials, signing out or uninstalling does not replace server-side revocation. Revocation prevents further use of the affected Connection; Runs already accepted are not automatically cancelled.

2.6 Use is permitted from the age of 16. Users under 18 require consent from a parent or legal guardian. Age and other required registration information must be accurate. Where there are reasonable doubts about eligibility, appropriate evidence may be requested and access temporarily restricted to the necessary extent. Statutory rights and the rules on Credits remain unaffected.

2.7 AI-generated results are not presented as human-authored professional examination or certification. zenture complies with regulatory duties applicable to its actual role, including applicable AI-system duties. An external model provider’s duties and zenture’s own duties are distinct; using a provider does not blanket-transfer responsibility for zenture’s own agreed service.

2.8 Optional new functions or additional paid offers may require separate conditions. They are not automatically included in existing plans. Changes to existing agreed services are governed by § 1.4.

2.9 Planned Learning features

The Learning features described below are planned and have not yet been implemented. They are intended primarily to develop zenture’s decision logic and review rules; where applicable, this may also include targeted adaptation of AI models through fine-tuning.

Where corresponding Learning features are offered, personal Learning for the respective user and Learning within the respective organisation can be configured through the designated settings. Neither mode receives a Learning discount.

Use of Run results for general, collective Learning to further develop zenture requires separate express authorisation by the user. Run results may also include embedded text excerpts, contextual information and personal or confidential details. To the extent necessary for the described Learning purpose and legally permissible, these elements may be included in the separate authorisation. This authorisation does not include complete Run inputs or uploaded files. Your authorisation alone does not give zenture rights to process every third-party personal record, organisation secret or special category of data. The necessary rights, legal bases and safeguards must exist for the data actually affected. This voluntary authorisation receives a discount under the described participation conditions. Before authorisation, the affected data, purposes of use, participation conditions and withdrawal options are explained. Neither acceptance of these Terms nor configuration of personal or organisation Learning replaces that separate authorisation.

You can disable authorisation for general zenture Learning at any time through the designated settings. From that point, the authorised Run results are no longer analysed for general zenture Learning on the basis of that authorisation. This also applies to already collected results and queued analyses; there is no additional processing period based on the disabled authorisation. The participation discount applies only while participation is active, not for periods before activation or after deactivation. Discounts legitimately granted for active participation are not retrospectively reclaimed because of deactivation.

Run results used for Learning, development of decision logic and review rules, or any fine-tuning are used exclusively for zenture’s internal purposes. We do not sell or publish this data or provide it for independent training or exploitation by external providers. Processing by the infrastructure service providers involved takes place solely within the described processing for zenture.

2.10 Offered AI quality evaluation (AQE) functions are distinct from any promise of error-free results. Their respective access, scope and Credit consumption follow the offer and price list; existing agreed access rights remain preserved. Examination is AI-assisted and is not human professional advice. Liability under § 7 remains applicable.

2.11 Guest access

2.11.1 zenture may, at its discretion, offer guest access, in particular via connections with third-party applications. Guest access is a voluntary, free-of-charge trial offering without a personal account. No additional voluntary entitlement to its provision, continuation or any particular scope of functionality is granted. Specific agreements and mandatory statutory rights remain unaffected.

2.11.2 The product describes the functionality, number and types of permitted operations (such as Runs), duration and retention periods of guest access. zenture may change, restrict or discontinue the voluntary offer for future use. Section 1.4 and statutory rights continue to apply to services already agreed and material changes to an existing contractual relationship. Necessary immediate protective measures under § 5.3.2 remain possible.

2.11.3 No Credits are issued, purchased or consumed and no payments are made under guest access. No additional contractual entitlement to Credit grants or repurchase is provided. Statutory performance, remedy and other rights remain unaffected.

2.11.4 By activating guest access, in particular by ticking the corresponding checkbox, the guest agrees to these Terms, acknowledges the Privacy Notice, and confirms meeting the requirements of § 2.6. Otherwise these Terms apply to guests unless this § 2.11 provides otherwise.

2.11.5 Guest access does not include an availability or result guarantee beyond the described functionality. The limitations of Run results under § 2.2 also apply here. Guest data is handled under the retention and deletion rules described in the Privacy Notice and the product. Revoking a Connection ends further access but is not the same as immediately deleting all data. Guests should save needed results in good time. Statutory information, data retrieval and other rights remain unaffected.

2.11.6 Liability towards guests is governed by § 7. The fact that guest access is free of charge does not by itself exclude mandatory statutory claims.

2.11.7 zenture may end guest access for future use. In cases of abuse, circumvention of limits, concrete security risks or an official order, access or Connections may also be blocked or revoked immediately under § 5.3.2. Accrued claims and required statutory notices remain unaffected. Guests may revoke a Connection at any time; merely stopping use does not replace revocation. Storage and deletion of guest data follow the Privacy Notice.

2.11.8 Prohibited in particular are creating or using multiple guest accesses to circumvent limits, unauthorized automated or mass use, and any circumvention of technical restrictions. Intended use of approved MCP or agent connections within the permissions granted and usage limits is permitted. Breaches of those limits may constitute material breaches of § 5; protective measures under § 5.3.2 remain permissible. zenture may process technical signals as described in the Privacy Notice to detect and prevent misuse.

2.11.9 The guest may register an account at any time. Data or connections from guest access are carried over only to the extent zenture technically offers this; there is no entitlement to such carry-over. From registration onwards these Terms apply without the particularities of this § 2.11.

2.12 Connections with applications

2.12.1 zenture may be used through its own clients and through independent third-party applications such as ChatGPT, Claude or Claude Code. A Connection permits only the actions described for it. Users bear the Credit consumption incurred under the applicable pricing conditions for use they initiate or authorise within the granted permissions. This does not create blanket liability for every action technically performed through the Connection; zenture remains responsible for its own errors and statutory rights remain unaffected.

2.12.2 Independent third-party applications are operated by their providers under their own terms and privacy notices. Their behaviour, availability, presentation of results and data processing fall within the respective provider’s responsibility. zenture remains responsible for its own clients and the integration services it has agreed to provide. Changes to or discontinuation of an access channel under existing contracts follow § 1.4; the availability of another channel does not automatically remove claims relating to an agreed service.

2.12.3 Users must be entitled to submit the content and files they send through a Connection. zenture processes the content and files transmitted through the Connection within the permitted functionality and permissions. The selection and confirmation steps offered by an independent application depend on that application. A Connection alone does not authorise blanket retrieval of all files or Account content.

2.12.4 Revocation does not delete data held by the provider of the third-party application and does not reverse operations already performed or Credit consumption already incurred. zenture may revoke connections, or require renewed permission, at any time for security reasons without prior notice.

§ 3 Service availability and support

3.1 zenture provides the agreed services within the offered functions. Unless expressly agreed separately, no uninterrupted availability, particular uptime percentage, support hours or fixed response or restoration times are promised. Statutory rights relating to service disruptions remain unaffected.

3.2 Maintenance, technical failures and necessary security or operational measures may temporarily restrict availability. We seek to limit such restrictions reasonably and address significant disruptions within our operational capabilities. No specific support processing, response or restoration times are promised unless expressly agreed separately.

3.3 Additional contractual service levels and associated remedies require a separate express agreement. Voluntary goodwill measures do not establish entitlement to similar measures in the future. Statutory performance, defect and other rights remain unaffected.

3.4 During a disruption, the particular agreed functions affected are relevant. Failure of one Chat model is not automatically complete unavailability of the platform; an available alternative does not automatically remove claims relating to a particular agreed service that has failed. Restrictions in the user’s own connection, devices or infrastructure are distinguished from zenture disruptions.

3.5 An expressly agreed remedy follows the respective agreement. Voluntary goodwill does not automatically replace statutory or previously acquired contractual entitlements. These Terms do not establish an additional Credit type for disruptions or goodwill. Support inquiries may be sent to [email protected].

§ 4 Credits and payments

4.1 Credits are technical usage units intended for zenture services. They are not freely transferable or redeemable for cash. Crediting Purchased Credits does not extinguish the duty to provide the agreed service or statutory rights under the underlying contract.

4.2 Credit types, allocation, consumption, validity and Account closure

(a) Three Credit types

(i) purchased: Credits acquired through a paid purchase for using agreed services. For new purchases under these Terms, each purchase forms a separate package with its purchase date and original validity of 24 months. Existing packages retain their originally agreed validity, including any previously agreed longer period. Statutory withdrawal and refund rights and existing contractual entitlements remain unaffected.

(ii) promotional: Credits issued free of charge for corresponding promotions, valid for 12 months from allocation. The respective promotion conditions determine eligibility, scope and restrictions. A voluntary allocation does not create entitlement to future promotions or further allocations.

(iii) subscription_bonus: Credits allocated under the respective subscription offer, generally for the respective billing period. They are valid for 12 months from allocation. An upgrade provides only the prorated additional allocation for the remaining period under § 8.6, not a second full-period allocation. Future allocations follow the plan applicable from the beginning of the next period.

(b) Consumption order

Credits are automatically consumed in this order: subscription_bonus, promotional and finally purchased. Within each type, the oldest Credits are consumed first. This order does not extend a package’s validity. Different purchase or allocation dates are not combined into a new common validity start date.

The 24 months for purchased Credits are determined per purchase: for example, a purchase under these conditions on 15 January 2027 has its original expiry on 15 January 2029. Other types each have 12 months from allocation. After expiry, contractual use ends subject to mandatory statutory rights and existing entitlements. No blanket cancellation of statutory claims through expiry is agreed.

Subscription cancellation, downgrade or Seat reduction alone does not delete allocated Credits or shorten their original validity. It ends or reduces future allocations according to the plan applicable when the change takes effect. Existing contractual promises about expiry displays and reminders remain preserved for the corresponding balances.

(d) No additional voluntary payout

For new agreements, unused purchased Credits do not carry a contractual right to payout or buyback on voluntary Account closure beyond statutory obligations. Merely cancelling a subscription is not closing an Account. Existing contractual buyback and refund entitlements remain preserved, including their agreed calculation and handling conditions. These Terms do not blanket-forfeit statutory or previously acquired entitlements.

Promotional and Subscription Bonus Credits do not create an additional right to payment of their calculated Credit value. This does not exclude rights arising from the underlying paid subscription or service relationship. In particular, withdrawal, defect, price-reduction, refund or damages claims are not excluded merely by labelling an allocation a bonus.

(e) Claim-specific handling

Where a refund is owed by law or under a previous agreement, it follows that basis, the affected purchase or period and applicable deadlines. Different packages and payments are not valued solely at a later general Credit rate. A new price list does not automatically increase or reduce an acquired refund entitlement. You can contact [email protected] to clarify a refund or existing buyback entitlement; an already owed automatic process is not thereby converted into a new application requirement.

Permissible payment, reversal or abuse checks follow § 4.8. Suspicion alone does not extinguish a valid claim. No additional automatic buyback service beyond statutory or existing contractual entitlements is promised.

4.3 Prices and Run consumption

4.3.1 Applicable prices, Credit allocations and consumption conditions are described in the price list at zenture.app/pricing.

4.3.2 Credit consumption for a Run is calculated internally from the zenture computing resources and processing used, under the pricing terms applicable to that Run. Billing is exclusively in Credits. The applicable plan factor may affect the consumption charged. A Credit reservation is not a final debit. Settlement charges the consumption due under the applicable pricing conditions and releases unused reservations. The pricing conditions recorded when the Run is accepted determine its billing. The price list also explains rounding and any substitute calculation used when measurements are unavailable.

4.3.3 Fast, Standard and Detailed have profile-specific minimum consumption to cover the minimum operating effort. Base consumption is the higher of calculated consumption and the minimum for the respective profile. The applicable plan factor is then applied. The minimum is not charged in addition to calculated consumption. Minimum values and plan factors are specified in the price list.

4.3.4 If processing of a Run does not begin, no Credits are charged for it. If you cancel after processing begins, the processing performed up to cancellation that is billable under the applicable pricing conditions is charged with the applicable plan factor. The profile-specific minimum consumption does not apply to such cancellation. A technical failure on zenture’s side does not, by itself, justify charging the minimum. Statutory rights regarding unprovided or defective performance remain unaffected.

4.4 Payment, payment failures and invoices

4.4.1 Available payment methods and the amount due are shown at purchase. Subscriptions are billed in advance. The price list applicable to the specific offer distinguishes purchase prices, subscription fees, allocations and consumption conditions; purchasing a balance is not the execution of a particular Run.

4.4.2 Consumer prices include applicable VAT. Business customers may be subject to different tax treatment, particularly for cross-border services. Required invoice and tax information must be accurate. Electronic invoices may be obtained through the designated billing channels or requested.

4.4.3 If a payment fails, we inform you about the affected payment; another collection is possible only within the given payment authorisation. If an amount due remains unpaid seven days after its due date, we may suspend the affected paid access to the necessary extent or return it to free access, where legally permitted. A payment failure does not automatically authorise deletion of personal content or forfeiture of independently acquired balances. Termination and further measures follow §§ 4.8, 5 and 8.7.

4.5 No additional voluntary refund entitlement is granted for Credits properly consumed or subscription periods provided. This does not exclude statutory refund, withdrawal or defect claims or existing contractual entitlements.

4.6 Auto-Recharge is activated only through your express configuration. You select the balance threshold and purchase amount. If the balance falls below that threshold, an additional Credit purchase is triggered under your settings and charged under the applicable pricing terms. Your configured purchase amount limits each individual trigger; further later triggers follow your active settings. You can disable Auto-Recharge at any time for future triggers. Deactivation does not automatically cancel a purchase already triggered; statutory rights remain unaffected.

4.7 Changes to pricing and consumption conditions

4.7.1 External model-provider or infrastructure costs may affect consumption rates for Chat functions. Run consumption instead follows zenture Compute and Processing under § 4.3. Using external models in Chat does not turn a Run into a purchase of external AI services.

4.7.2 Significant, sustained changes to relevant costs may justify adjustment of affected consumption rates where a valid basis for change exists. Cost-based increases must be reasonable and proportional to the underlying cost change. Corresponding sustained cost decreases are considered when reviewing the respective rates; temporary promotions or decreases offset by other relevant cost increases do not create automatic pass-through. § 1.4 and mandatory law remain applicable.

4.7.3 Before increasing existing consumption rates, we generally give at least 30 days’ advance notice by email or platform notice identifying affected functions, previous and new rates, effective date and applicable agreement and termination rights. On request, we reasonably explain the basis without having to disclose confidential service-provider contract conditions. Referring to a new price list does not replace this information.

4.7.4 Affected users may terminate because of the corresponding material change by notifying [email protected] before it takes effect, with termination effective on the change date. Prepaid services, balances and existing entitlements are treated under §§ 4.2 and 8.7. Silence does not replace required acceptance that has not been given.

4.7.5 Adjusting a consumption rate is distinct from changing the nominal Credit purchase price or subscription fee. These amounts do not automatically change through a consumption-rate adjustment; the required information, agreements and § 1.4 apply separately. A new price list does not retrospectively increase charges for completed purchases or already accepted Runs.

4.8 Fraud, payment disputes and Account compromise

4.8.1 Where there are concrete indications of fraud, abusive chargebacks or unauthorised use, we may review affected transactions, request necessary information and temporarily restrict affected access to the necessary extent. Credits not validly acquired or demonstrably obtained through abuse may be corrected to the affected extent. Measures must be proportionate to the particular transaction and risk; they are not automatic permanent termination.

4.8.2 A legitimate payment complaint, proven unauthorised use of a payment method or zenture billing error is not abuse merely because a reversal occurs. Statutory refund rights and existing entitlements are not excluded by suspicion alone. Using a designated payment-dispute procedure does not blanket-forfeit all Credits.

4.8.3 Correcting affected payment allocations is distinct from additional damages or cost recovery. Any further set-off requires an existing legally enforceable claim and statutory set-off requirements. These Terms do not create an automatic flat penalty deduction or additional chargeback fee. Established abuse may justify measures under §§ 5 and 8.7.

4.8.4 You should promptly report unauthorised access to [email protected]. We review the affected period and appropriate protective measures; necessary incident information may be requested. Whether consumption must be corrected or a claim compensated depends on established circumstances and applicable law. No blanket responsibility for every use before your report or automatic exemption from zenture liability is agreed.

4.8.5 We communicate relevant restrictions and necessary steps appropriately unless prohibited by law or detrimental to legitimate security or investigation purposes. Payments, refunds or legitimate Account claims can be clarified through [email protected]; statutory complaint and remedy channels remain available.

§ 5 Permitted use

5.1 The service may be used only for lawful purposes and through authorised access methods. Users must have the necessary rights to submitted content and respect third-party rights.

5.2 Prohibited conduct includes unlawful content, malicious code, bypassing security or access controls, abusive automated access, systematic scraping without necessary permission, unauthorised resale or sublicensing, deception about identity or eligibility, and unlawful harm to zenture, users or third parties. Reverse engineering or other interference is prohibited except where mandatory law permits it. Offered API and MCP use is not blanket-prohibited automated access; its authorised permissions and limits apply. Legally permitted conduct and rights are not excluded.

5.3 Procedure for violations

5.3.1 For a remediable violation, we generally identify it in writing and request a remedy. In ordinary cases, the previously provided cure period of five business days is granted unless a different statutory or already agreed rule applies. Failure to remedy or repeated material violations may justify further proportionate measures.

5.3.2 Immediate protective measures may be appropriate particularly for significant security risks, stolen credentials, fraud, material harm or a statutory obligation. Repeated violations after a previous warning are assessed according to their particular seriousness. An inaccurate age statement is not automatically fraud in every case or grounds for forfeiting all balances.

5.3.3 Possible measures include restricting an affected function, temporary access suspension, legally required content removal and, where its requirements are met, termination for cause under § 8.7. Statutorily permitted reports and substantiated compensation claims remain possible. Duration and scope follow the reason and necessity. Claims and balances are treated under § 4; suspicion alone does not cause their blanket loss.

§ 6 Intellectual property and feedback

6.1 Rights in the platform belong to or are licensed to zenture. Users receive the rights designated for the agreed use of the service.

6.2 Existing rights in your inputs and results remain with the respective rightsholder. You grant zenture the nonexclusive use rights necessary to provide the functions you request. This includes storage, processing and display necessary for those functions.

Any use of Run results beyond that scope for general zenture Learning is governed by the designated separate express authorisation. This provision does not constitute a blanket transfer of rights in user content to zenture. We do not guarantee that AI-generated results are protected by copyright or that exclusive rights in them exist. Existing third-party rights remain unaffected.

6.3 zenture may use voluntarily submitted general product suggestions and improvement ideas to develop the product without additional remuneration. To the extent necessary for that purpose, you grant zenture a nonexclusive right to use those suggestions. This provision does not constitute blanket authorisation to use Run content or personal or confidential details contained in it, and does not replace separate authorisation for general zenture Learning.

6.4 AI-generated results may contain already protected elements or reflect human creative contributions. This does not create a blanket promise of an exclusive right belonging to the user in every output. For your intended use, you must respect existing third-party rights and applicable legal requirements. Conditions of a model provider used for Chat apply only to the extent they validly govern that particular use; they do not create general authorisation for your Run content. zenture’s own liability follows § 7.

§ 7 Liability

7.1 zenture is liable without limitation for intent and gross negligence, for injury to life, body or health, and under mandatory statutory liability provisions. Liability arising from an expressly assumed guarantee also remains unaffected.

7.2 For ordinary negligence, zenture is liable only for breach of essential contractual duties. These are duties whose performance is necessary for proper performance of the contract and on whose fulfilment you may normally rely. In such cases, liability is limited to the foreseeable damage typical of the contract at the time the contract is concluded. Otherwise, liability for ordinary negligence is excluded.

7.3 These limitations also apply for the benefit of zenture’s legal representatives, employees and persons engaged to perform its obligations. Mandatory statutory claims, including under the German Product Liability Act and data-protection liability provisions, remain unaffected. Statutory rights relating to defective performance are not excluded by this liability provision.

7.4 External providers may affect functions, availability and outputs of their Chat models. zenture does not guarantee error-free AI output or unrestricted external model availability; its own agreed service and the liability rules in this § 7 remain applicable. Users must reasonably review results for their intended use and comply with their own legal obligations. This is not a blanket exclusion of liability for zenture’s own breaches.

7.5 For business customers, aggregate liability for ordinary negligence arising from all damage-causing events in the respective contractual year is capped at the higher of EUR 500 or the fees paid to zenture by that business customer under the affected contract in the twelve months preceding the first damage-causing event in that contractual year, to the extent this limitation can validly be agreed. A contractual year starts when the affected contract is concluded and subsequently on each anniversary. The relevant year is the year in which the damage-causing event occurs. Fees from other contracts or other customers are not combined. The cap does not apply to § 7.1, mandatory claims under § 7.3 or consumers. § 7.2 otherwise remains applicable.

7.6 Business customers indemnify zenture and its legal representatives, employees and agents to the legally permitted extent against substantiated third-party claims and reasonable necessary legal costs insofar as caused by culpable unlawful use under § 5, culpably unlawful processing of personal data or infringing content supplied by the business customer. Any share of responsibility attributable to zenture itself is not transferred to the business customer. Mandatory liability rules and the rights of affected third parties remain unaffected.

7.7 Indemnification for the affected third-party claim, including related costs, is capped at the higher of EUR 10,000 or the fees paid to zenture by that business customer under the affected contract in the twelve months preceding the event giving rise to the claim; the cap does not apply to intentional misconduct or fraud by the business customer. zenture provides appropriate information about the claim and allows reasonable participation in reviewing and defending it. An unconfirmed third-party allegation alone does not create an automatic payment obligation. This provision does not apply to consumers.

§ 8 Subscriptions, organisations, cancellation and programmes

8.1 Accounts and subscriptions are distinct. A free Account or pay-as-you-go access has no minimum subscription term and may be used with Purchased Credits; a subscription grants the plan conditions and Credit allocations described in the price list. Monthly subscriptions are currently offered for private users and organisations.

8.2 Plan conditions and special eligibility

8.2.1 Names, services, prices, billing periods, Credit allocations and consumption conditions follow the respective offer and price list. Monthly subscriptions are currently offered to individuals and organisations. Without cancellation, a plan continues under its validly agreed conditions. This does not automatically agree a new annual term.

8.2.2 Where an Academic or other eligibility-based plan is offered, its described requirements must be met and substantiated upon a permissible request. Reverification may be necessary. If required eligibility is not confirmed, any change follows the offer, required notice and § 1.4. Already agreed notice periods remain preserved; requesting evidence alone does not create a new fee.

8.3 Organisation members, seats and content

(a) Authorised organisation administrators can manage designated membership, seat and billing functions. Additional seats are charged immediately and proportionally for the remaining part of the current billing period, under the applicable pricing terms.

(b) A reduction in billable seat quantity takes effect at the start of the next billing period. No additional voluntary prorated refund is granted for the current period. Removing a member ends their organisation access immediately, independently of seat billing timing. Statutory rights remain unaffected.

(c) Removal does not close the personal Account or end access to owned Run content. No new Runs may then be started at the organisation's expense. Runs already accepted are not automatically cancelled. Retention and deletion rules remain unaffected.

(d) A later organisation feature is intended to provide authorised administrators with summarised Insights from Run usage. This does not include complete individual Runs with inputs, files and detailed results. This feature is planned and is not currently available; scope, processing and permissions will be explained before introduction.

8.4 You can cancel your subscription at any time without an additional notice period, effective at the end of the current billing period. Agreed plan access remains available until then. Statutory early-termination rights remain unaffected.

8.5 Subscription cancellation and Account closure

8.5.1 A subscription may be cancelled through the designated Account settings or by notifying [email protected]. Under § 8.4 it ends at the close of the current billing period. The personal Account remains and may subsequently be used within the offered free or pay-as-you-go scope. Allocated Credits retain their original validity; cancellation does not trigger an additional voluntary payout.

8.5.2 Account closure is separate from subscription cancellation and may be requested through the offered Account-deletion function or by contacting [email protected]. After a deletion request has been successfully verified, further Account access is blocked and cleanup of the associated data is initiated; cleanup may continue afterwards. Existing balance and refund entitlements follow § 4.2. Outstanding payments, statutory obligations and acquired rights are not extinguished merely by a deletion request. Storage and deletion of individual data categories follow the Privacy Notice. Immediate deletion of every backup or service-provider copy is not promised.

8.6 Upgrades take effect immediately after successful payment. The prorated price difference is charged and additional Credit allocation granted proportionally for the remainder of the current billing period; no duplicate full allocation. The billing cycle generally remains unchanged. Downgrades and subscription cancellations take effect at the end of the current period. Credits already allocated retain their original validity.

8.7 Termination by zenture

8.7.1 Ordinary termination of free or pay-as-you-go access or a currently offered monthly subscription is generally notified to the registered email address at least 30 days in advance, unless another valid agreement or mandatory law applies. Already agreed longer periods, particularly from historical contracts, remain preserved. This does not introduce a currently offered annual subscription.

8.7.2 When zenture terminates without breach by the user, prepaid services no longer to be delivered are treated under statutory or already agreed rules. Existing prorated refund entitlements for unused prepaid subscription periods remain preserved; where a corresponding time-based agreement applies, calculation follows the period of access no longer provided. Balances and previous buyback entitlements follow § 4.2. Calling an allocation a Credit or bonus does not remove these claims.

8.7.3 Termination for cause requires a material ground and the relevant statutory requirements. These may include significant unremedied breaches, established payment or identity fraud, proven chargeback abuse, or statutory or official obligations. Remediable violations follow § 5.3; any legally required warning or cure period must be observed. Suspicion, a legitimate payment complaint or every inaccurate age statement is not automatically grounds for termination.

8.7.4 Termination does not blanket-forfeit all Credits, create an automatic additional penalty or generally exclude statutory refund rights. Permissible corrections, compensation claims and set-offs follow § 4.8 and applicable law. Statutory access, deletion and content-return rights and existing export rights remain preserved.

8.7.5 The termination notice generally identifies the reason, effective timing and treatment of affected prepaid services, balances and existing entitlements. Where relevant, it explains necessary steps to exercise existing content or export rights. Security or legally required restrictions must not unlawfully reduce mandatory information. Already agreed contractual export windows remain preserved; provision follows agreed rights and statutory requirements.

8.8 Existing conditions and Legacy plans

8.8.1 New plans or prices for new subscribers do not by themselves replace existing subscription conditions. Existing subscribers retain their agreed plan unless changed on a valid basis under § 1.4 or voluntarily changed by the user.

8.8.2 Closing a Legacy plan to new users does not automatically migrate existing subscribers to another plan. A voluntary change follows the offered new plan and § 8.6. Allocated Credits and acquired entitlements remain preserved under § 4.2. Discontinuing an offer for new customers alone does not terminate ongoing contracts.

8.8.3 Where a Legacy plan is discontinued or materially changed for existing subscribers, the corresponding information, agreement and termination rights under § 1.4 and § 8.7 apply. Already agreed special continuity rights remain preserved. A new name or price list cannot retrospectively remove them.

8.9 Referral, partner and acquisition programmes

(a) Participation and benefits are additionally subject to the described programme participation and benefit conditions. These define eligibility, scope and restrictions and are made accessible before participation. A partner inquiry alone does not create admission or remuneration.

(b) Referral benefits require a verified email address and activity by the referred user on at least two distinct UTC calendar dates. Registration alone does not create a benefit. Further requirements and specific benefits are described in the relevant conditions.

(c) Partner participation requires separate confirmation. Partners must advertise truthfully, provide required commercial disclosures and comply with advertising, competition, privacy and tax law. Spam, misleading performance claims, unauthorised representation of zenture and abusive customer attribution are prohibited.

(d) Partner remuneration applies only to qualifying revenue from referred private customers during the first twelve months from each customer's registration. Organisation revenue is excluded. Revenue takes discounts and taxes into account; refunds and lost payment disputes cause corresponding adjustments. Rates and further eligibility requirements follow the described partner conditions. The period is determined separately per referred customer; payment follows its end and completion of necessary checks under the partner conditions.

(e) zenture may verify eligibility, customer attribution and concrete indications of fraud or abuse and request necessary information or evidence. Where suspicion is reasonably grounded, the affected payment may be temporarily deferred pending clarification. Checks take place within a reasonable time. Remuneration may be denied or corrected to the extent requirements are not met or fraud or abuse is established. Valid entitlements remain unaffected. Changes to future programme offers do not extinguish acquired entitlements.

(f) A partner inquiry or participation does not by itself create exclusivity, authority to represent zenture, employment, a franchise or reseller relationship, or permission to incur obligations in zenture’s name. Participation requires separate written confirmation. Before participation, the remuneration rate, qualification, attribution, payout conditions and required evidence are described. An advertised maximum rate is not guaranteed remuneration for every referral.

(g) Partners must not guarantee AI results, impersonate zenture or bid on protected brand terms without permission. Processing or disclosing third-party contact details requires the necessary rights and legal bases. Partner confirmation does not replace independent tax or business obligations.

(h) We may reject participation or reasonably pause or end it for concrete contractual, abuse, regulatory or brand risks. Programme changes apply to future participation and offers under applicable conditions; validly acquired remuneration entitlements remain preserved. There is no right to future referrals, customers, unchanged future programme offers or remuneration after the respective described first year unless separately agreed.

§ 9 Force majeure and disruptions

9.1 Events outside a party's reasonable control, such as natural disasters, war, government measures or widespread infrastructure disruption, have the consequences provided by law. The affected party makes reasonable efforts to limit the effects.

9.2 Permanent impossibility or discontinuation of agreed services does not extinguish statutory or existing contractual termination and refund rights. Service-provider failure does not constitute a blanket exclusion of responsibility for zenture's own agreed performance; § 7 remains applicable.

9.3 The affected party communicates significant disruption as soon as reasonably possible and seeks reasonable remedies and limitation of its effects. Temporary restrictions are distinguished from permanent closure. Where a force-majeure event lasts longer than 30 days, the previously provided right of either party to terminate in text form, for example by email remains preserved; statutory requirements and treatment of services no longer to be provided remain applicable.

9.4 An external Chat-model outage, a local user problem and failure of zenture’s own Run processing are assessed according to the respective service affected. Temporary disruption does not carry an automatic voluntary balance payout; statutory and already agreed entitlements remain. Permanent closure or impossibility does not permit blanket retention of all prepaid services.

§ 10 Transfer of the contract

10.1 Transfer to another operator requires a valid contractual or statutory basis. Existing obligations and entitlements, including statutory or previously agreed refunds, remain preserved. Affected users are informed under applicable requirements; required consent and objection or termination rights remain unaffected.

10.2 Users may transfer rights and obligations only with our consent unless otherwise provided by law.

10.3 A transfer by zenture, for example during a business acquisition, is generally announced at least 30 days in advance. The successor must assume the affected contractual obligations and existing entitlements; agreed service levels must not be materially reduced merely through transfer. Any additionally required consent to transfer is obtained.

10.4 Consumers may object in text form, for example by email to [email protected], within 30 days after the transfer notice. Legal consequences, including any termination effective on the transfer date, follow the valid transfer basis and applicable law. Affected balances and prepaid services no longer provided are treated under §§ 4.2 and 8.7. Already agreed additional objection or termination rights, including historical contracts, remain preserved.

§ 11 Consumer protection

11.1 This section applies to consumers. Mandatory consumer rights are not excluded by these Terms.

11.2 For distance contracts, a 14-day withdrawal right from contract conclusion applies where provided by law. The withdrawal notice and information required for the respective purchase are provided during purchase. An unambiguous withdrawal declaration may in particular be sent to [email protected]. Consequences follow applicable law; refunds required by law are made within statutory deadlines.

11.3 Model withdrawal form (use is optional):

To: zenture UG (haftungsbeschränkt), Dobelstrasse 5, 70184 Stuttgart, Germany, [email protected]

I/We (*) withdraw from my/our (*) contract for: [description of the service].

Ordered on: __________ | Name: __________ | Address: __________

Signature (paper form only): __________ | Date: __________

(*) Delete as appropriate.

11.4 Crediting or using Credits does not automatically extinguish a statutory withdrawal right. Compensation for use or expiry of the right requires the respective statutory conditions, information and declarations. Agreement to these Terms alone is not a blanket separate declaration permitting early expiry. Paid-subscription claims are not excluded merely by describing Credit allocations as bonuses.

11.5 zenture does not participate in consumer dispute-resolution proceedings. Mandatory information or participation requirements remain unaffected.

11.6 German law applies subject to mandatory consumer protection under applicable law, particularly at the consumer's habitual residence.

11.7 Additional withdrawal explanations

11.7.1 Statutory withdrawal does not require reasons. For subscriptions and individual Credit purchases, the respective contract conclusion is relevant; the period starts and ends under statutory requirements, including proper information. An unequivocal declaration must be sent before the deadline. Using the model form is voluntary.

11.7.2 Where statutory withdrawal is effective, refunds owed are generally made no later than 14 days after receipt of the withdrawal declaration using the payment method used for payment, unless another fee-free method has validly been agreed. Statutory exceptions remain applicable. Any permissible compensation for performance is assessed separately from blanket non-refundability.

11.7.3 For services, any compensation for early performance requires, in particular, an express consumer request for early commencement and the required information. Such a request is not inferred solely from accepting these Terms or completing checkout. Digital content follows its particular statutory requirements. Technical Credit allocation or consumption alone does not determine this legal classification.

11.7.4 Unused Credits from an effectively withdrawn and reversed purchase are not additionally retained as spendable balance. Already provided services may be taken into account only to the legally permitted extent. No independent purchase price is repaid for freely allocated Credits; rights arising from a paid subscription or other underlying service remain unaffected. The specific purchase flow must separately provide the required information and declarations.

§ 12 Data protection and service providers

12.1 The Privacy Notice at zenture.app/privacy-notice describes data, purposes, recipients, retention and rights. Acknowledging that information is not blanket consent to all processing. Optional analytics and general Learning authorisations are separate.

12.2 Data-protection roles follow actual processing. Organisation participation or payment alone does not make zenture a processor for every operation. Where processing on behalf of a business customer requires an Article 28 GDPR agreement, that agreement must be concluded before such use. A standard DPA is not currently provided through the website; inquiries should be sent to [email protected]. zenture may act as controller for its own Account, security, billing and other independent purposes. Calling a service self-service does not remove a required DPA obligation.

12.3 Subprocessors, information and objections

12.3.1 The overview at zenture.app/subprocessors describes service providers and their respective functions, data categories and, where relevant to the processing, locations and transfer safeguards. Listing a provider is not blanket permission for every possible purpose or data category.

12.3.2 Where zenture processes on behalf of a business customer, authorisation of further subprocessors and changes follow Article 28 GDPR and the agreed DPA. Acceptance of general Terms does not replace a required DPA or consent required outside that processing. A validly agreed general-authorisation framework carries its associated information and objection rights.

12.3.3 The previously agreed framework of at least 14 days’ advance email information before a new subprocessor processes affected business-customer data, and objection within that period, remains preserved where part of the respective agreement. Different mandatory or separately agreed rights remain unaffected. A reasoned objection is sent to [email protected] and identifies substantiated data-protection grounds; purely commercial grounds do not replace these.

12.3.4 Following a justified objection, we make reasonable efforts toward a legally and technically suitable alternative configuration or resolution of the grounds. If unsuccessful within the already agreed 30-day framework, agreed termination rights for affected services remain preserved. Ending an individual service is not automatically complete Account closure. Prepaid services and balances follow §§ 4.2 and 8.7; statutory claims are not excluded.

12.3.5 We agree the applicable data-protection obligations with required subprocessors. Statutory responsibility for agreed processing and duties toward business customers and data subjects are not blanket-shifted to providers. Where a Chat model provider acts exclusively on instructions, that processing is distinguished from the provider’s own purposes requiring separate legal assessment; the actual role follows the specific service and contract.

12.4 External AI model providers receive data designated for the requested Chat function. Runs are executed within zenture processing with the designated infrastructure providers. No general transfer of all Run content to external AI model providers is authorised. Planned Learning and possible fine-tuning follow § 2.9 and the Privacy information provided before introduction.

§ 13 Additional notices for use in the United States

13.1 The general service and liability provisions of these Terms, in particular §§ 2 and 7, also apply when the Service is used in the United States. Mandatory rights under applicable law remain unaffected. Accessing the Service from the United States does not by itself change the contracting party or previously agreed contractual terms.

13.2 This version does not introduce an additional obligation to use AAA arbitration, a separate class-action waiver or an additional US liability cap. Separate or previously valid agreements are not automatically cancelled by this provision; amendments follow § 1.4 and applicable law. Governing law and jurisdiction follow § 14, preserving mandatory rights.

13.3 Export Control and Sanctions. The Service may be subject to US, EU, and other applicable export control and sanctions laws. US Users represent and warrant that: (a) they are not located in, resident in, or ordinarily resident in any country or territory subject to comprehensive US trade sanctions or embargoes; and (b) they are not listed on any US government prohibited or restricted party list, including the SDN list maintained by the US Department of the Treasury. Users must not use the Service in violation of applicable export control, sanctions, or trade restriction laws. Platform Operator may suspend or terminate access to comply with applicable export control or sanctions laws.

13.4 Copyright / DMCA. The Platform Operator respects intellectual property rights and expects Users to do the same. Copyright holders who believe content available through the Service infringes their copyright under US law may submit a notice under the Digital Millennium Copyright Act (DMCA) to [email protected], including sufficient information to identify the allegedly infringing material. Upon receipt of a valid notice, the Platform Operator may remove or disable access to the content and may suspend or terminate the accounts of repeat infringers where appropriate.

§ 14 General Provisions

14.1 Governing Law. German law (excl. CISG) governs these Terms and all disputes (including non-contractual) for all Users, preserving mandatory consumer protections at their habitual residence insofar as applicable law makes them relevant and they cannot be contractually excluded; B2B jurisdiction: Stuttgart, Germany.

14.2 Jurisdiction. B2B: exclusive jurisdiction Stuttgart, Germany (to the extent permitted by law). B2C: the above does not affect B2C Users' statutory right to bring proceedings before the courts of their place of residence.

14.3 If individual provisions are invalid, the remaining provisions continue under applicable law. Statutory rules replace invalid provisions; no automatic reduction to the narrowest enforceable version is agreed.

14.4 Individual agreements and previously acquired entitlements remain unaffected. These Terms apply with the respective price list and any agreed DPA. The Privacy Notice provides information about processing; it does not replace required separate consent.

14.5 Waiver. Failure to exercise or enforce any right or provision does not constitute a waiver.

14.6 Language. These Terms are provided in German and English; both are legally binding. Conflicts: German version prevails for German residents; English version prevails for others (unless mandatory local consumer law requires otherwise). Both versions maintained with identical structure and updated simultaneously.
