Terms of Service

Effective date: 17 April 2026Last updated: 17 April 2026

Effective date: 17 April 2026 Last updated: 17 April 2026

These Terms of Service ("Terms") form a binding legal agreement between you ("you", "User") and Zamyrailov Oleksii, an individual entrepreneur (eenmanszaak) registered in the Netherlands ("we", "us", "Rinjani", "the Service"), governing your access to and use of the platform available at rinjani.ai and all related services (collectively, the "Service").

By creating an account, purchasing credits, or otherwise using the Service, you confirm that you have read, understood and agreed to these Terms. If you do not agree, do not use the Service.

1. About us

Service operator: Zamyrailov Oleksii, eenmanszaak KvK number: 98987712 VAT (BTW) number: NL005365684B76 Registered location: Utrecht, the Netherlands General contact: [email protected] Legal and privacy contact: [email protected] Website: https://rinjani.ai

The Service is currently offered as an open public beta. While the Service is fully functional and real payments apply, features, pricing and available models may change, and short service interruptions may occur. No service level agreement ("SLA") is provided at this stage.

2. What the Service does

Rinjani is a platform for generating and comparing images produced by multiple third-party AI image generation models. The Service includes:

  • Studio — a paid workspace where you enter a prompt and receive generated images from selected AI models. Studio is billed via prepaid service credits (see Section 7).
  • Arena — a free tool where users vote anonymously on outputs from different models. Voting data is used to improve our internal model recommendation engine (see Sections 9 and 11).
  • Supported models — the list of available models is published at https://rinjani.ai/models and may be updated from time to time. Third-party models are provided by external API providers (including, but not limited to, Replicate, FAL, OpenAI, Google Gemini and Leonardo).

Additional features (such as image-to-image generation, video generation, subscriptions and category leaderboards) may be added later and will be subject to these Terms or updated terms as needed.

3. Eligibility

You may use the Service only if:

  • you are at least 18 years old;
  • you have full legal capacity to enter into a binding contract under the laws applicable to you;
  • you are not barred from using the Service under any applicable law, sanctions regime or export-control rule;
  • you use the Service in compliance with these Terms and all applicable laws.

We may refuse service, close accounts or restrict access at our reasonable discretion, in particular where we believe the eligibility requirements are not met.

4. Your account

4.1 Registration

To use paid features you must create an account. During registration we collect an email address, a username (not required to be unique) and a password (which we store only as a cryptographic hash). You may also sign in using supported OAuth providers (currently GitHub and Google); additional providers may be added later.

4.2 Account security

You are responsible for keeping your credentials secure and for all activity on your account. Notify us at [email protected] immediately if you suspect unauthorised access.

4.3 One account per person

Unless expressly permitted by us in writing, you may register only one account. Creating multiple accounts to abuse free Arena credits, bypass restrictions, or game the recommendation system is prohibited.

4.4 Inactivity and account deletion

If you do not sign in for twelve (12) consecutive months, we will send you a notification to the email associated with your account and, after a reasonable grace period, close the account. Account closure results in loss of any unused credits, which will not be refunded. Data deletion following account closure is governed by our Privacy Policy and is not instantaneous, giving you a window to react after notification.

You may also close your account at any time via your account settings or by contacting [email protected].

5. Acceptable use

You agree not to use the Service to create, upload, submit, store or distribute content that:

  • depicts minors in a sexual or suggestive context (zero tolerance — reports will be forwarded to competent authorities);
  • depicts real, identifiable persons in a sexual, intimate or defamatory context without their verifiable consent ("non-consensual intimate imagery", "deepfake" pornography);
  • is designed to impersonate, defame or harass a specific real person;
  • promotes terrorism, violent extremism, genocide, or incitement to violence against persons or groups;
  • contains or facilitates child sexual abuse material (CSAM);
  • infringes intellectual property rights, trademarks, publicity rights or privacy rights of third parties;
  • is intended to deceive (e.g. political disinformation, fake official documents, forged identity documents, fraudulent imagery);
  • violates applicable law or the acceptable use policies of the underlying model providers (which you acknowledge apply in addition to these Terms).

You further agree not to:

  • attempt to bypass, disable or interfere with content filters, rate limits or security measures;
  • reverse-engineer, scrape or systematically extract outputs from the Service other than your own;
  • use the Service to train competing generative AI models;
  • resell, sublicense or make the Service available to third parties without our written permission;
  • use the Service to generate content in bulk for spam, SEO manipulation or automated abuse;
  • probe, penetration-test or attack the Service without prior written authorisation.

We operate automated and manual moderation. We may remove content, refuse generations, suspend access or terminate accounts that we reasonably believe violate this Section. Repeat or serious violations lead to permanent bans without refund of unused credits.

6. Reporting abuse and notice-and-action

If you believe content generated or hosted via the Service violates these Terms or your rights (including intellectual property rights), send a notice to [email protected] including:

  • your name and contact details;
  • identification of the content or account in question (URL, user, timestamp where possible);
  • a description of the alleged violation and, where relevant, the legal basis;
  • a statement made in good faith that the information is accurate.

We review reports and take appropriate action, which may include removing content, restricting accounts, or informing the reporter and the affected user of the outcome. We cooperate with competent authorities when legally required.

7. Prepaid credits, billing and refunds

7.1 Nature of credits

Paid use of the Service is billed through prepaid service credits ("Credits") loaded into your in-app wallet. Credits are an internal unit of account used solely to pay for generations within the Service. Credits:

  • are not electronic money within the meaning of Directive 2009/110/EC;
  • cannot be exchanged for cash, withdrawn, transferred to another user or to a third party, or redeemed outside the Service;
  • have no monetary value outside the Service;
  • are non-interest-bearing.

7.2 Purchase and payment

Payments are processed by Stripe, our payment service provider. By purchasing Credits, you also accept Stripe's terms where applicable. Prices are shown at the point of purchase and include applicable VAT for EU consumers where required. Stripe Tax is used to calculate and collect VAT based on your location.

7.3 Consumption and refunds

Credits are consumed only upon successful generation by the selected model. If a generation fails due to a provider error or technical fault on our side, Credits are not charged.

  • Consumed Credits are non-refundable. When you initiate a generation, you expressly request immediate performance of the digital service and acknowledge that you thereby lose your right of withdrawal for those Credits under Article 16(m) of Directive 2011/83/EU on Consumer Rights.
  • Unused Credits are non-refundable by default. However, at our sole discretion, we may grant goodwill refunds for unused Credits upon request sent to [email protected] within 14 days of purchase, provided no Credits from that purchase have been consumed.
  • Technical errors. If you believe Credits were charged in error (for example due to a bug or failed generation that was nevertheless billed), contact [email protected] within 14 days of the event. We will investigate and, where appropriate, restore Credits or refund the corresponding amount.

7.4 No expiry of Credits

Credits themselves do not expire. However, Credits are lost when the associated account is closed, including as a result of prolonged inactivity (Section 4.4) or termination for breach (Section 13).

7.5 Price changes

We may change pricing for future Credit purchases or generations. Price changes do not affect Credits already in your wallet, but the cost (in Credits) of individual generations may change; the applicable cost is always displayed before you confirm a generation.

7.6 Taxes

Prices displayed at checkout include all applicable indirect taxes (such as VAT/BTW) where required by law. You are responsible for any other taxes arising from your use of the Service under your local law.

7.7 Invoices

Invoices are issued electronically and made available in your account. We retain financial records for at least seven (7) years as required by Dutch tax law.

8. Third-party AI providers

Generations are produced by third-party AI models operated by external providers, including (without limitation) Replicate, FAL, OpenAI, Google Gemini and Leonardo. By using the Service, you acknowledge and agree that:

  • your prompt and certain associated metadata are transmitted to the relevant provider for the sole purpose of generating the requested output;
  • each provider has its own terms, privacy policies and acceptable use rules, which apply in addition to these Terms;
  • model availability, pricing, generation time and output quality depend on third parties and may change without notice;
  • we do not control and are not responsible for outputs generated by third-party models, save for our obligations under mandatory law;
  • rights to outputs may be subject to restrictions imposed by the relevant model provider.

8.1 Provider fallback and re-routing

To improve reliability, the Service may use multiple providers capable of running the same or an equivalent model. If the primary provider for a selected model is unavailable, returns an error, is rate-limited, or is otherwise unable to fulfil the request, we may automatically re-route the request to an alternative provider that offers the same or an equivalent model ("fallback"). By using the Service, you consent to this fallback mechanism and to the transmission of your prompt and associated metadata to any such alternative provider on the same terms as the primary one. The provider actually used for a given generation is not displayed in the user interface; on request we can provide this information for your own generations as part of a data access request.

8.2 Where to find provider terms

The current list of supported models, primary and fallback providers, and links to each provider's terms, privacy policy and acceptable-use policy is maintained at https://rinjani.ai/models. That page is referenced in and forms part of these Terms. Additions, removals or updates to the list do not require re-acceptance of these Terms.

9. Intellectual property

9.1 Your prompts

You retain ownership of the prompts you submit. By submitting a prompt, you grant us a worldwide, non-exclusive, royalty-free licence to process it for the purpose of operating the Service (including transmitting it to the relevant model provider, storing it as part of your history, and — where applicable under Section 11 — using it to train our recommendation system).

9.2 Generated outputs in Studio

Subject to the rules of the underlying model provider, and to the extent we have rights to assign, you receive the same rights in Studio-generated outputs that the model provider grants to end users — typically including commercial use, with exceptions where the provider imposes restrictions. You are solely responsible for verifying that your intended use of an output complies with:

  • the relevant provider's terms;
  • applicable law (including copyright, trademark, right of publicity and privacy law);
  • the rights of any persons or brands depicted.

We make no warranty that outputs are original, non-infringing, accurate or fit for any particular purpose.

9.3 Generated outputs in Arena

Outputs displayed in Arena for voting purposes are generated in the same way and governed by the same provider-level rules, but are produced specifically for comparison and data collection. You acknowledge that Arena outputs may be used internally by us as described in Section 11.

9.4 Our platform

The Service, including its software, design, logos, and internal recommendation and ranking models, is owned by us or our licensors and is protected by intellectual property law. These Terms do not grant you any right to our trademarks or to copy, modify or create derivative works of our platform.

9.5 Feedback

If you send us suggestions or feedback, you grant us a perpetual, irrevocable, royalty-free licence to use them without restriction.

10. Privacy and data protection

Our collection and use of personal data are governed by our Privacy Policy, available at https://rinjani.ai/privacy, which forms an integral part of these Terms. The Privacy Policy explains what data we process, on which legal basis, for how long, and your rights under the EU General Data Protection Regulation (GDPR) and Dutch implementing law.

11. Arena participation and use of data for model training

Arena is a crowdsourced benchmarking tool. It is designed to produce data that improves our internal model recommendation engine. Participation in Arena is therefore inherently linked to data collection for that purpose.

By participating in Arena (including by casting votes or submitting prompts to Arena), you:

  • confirm that you understand and agree that your prompts, model outputs compared in Arena, your votes, and limited associated metadata are used by us for the purpose of improving and training our recommendation models and related classifiers;
  • agree that, before such data is used for training, it is anonymised — that is, associated user identifiers are irreversibly removed. After anonymisation the data can no longer be linked to you, and you acknowledge that requests for deletion cannot be fulfilled for the anonymised dataset, because it is no longer personal data;
  • confirm that you do not include personal data about yourself or third parties in your Arena prompts, or, if you do, that you have all necessary rights and consents.

If you do not wish your data to be used as described above, do not participate in Arena. Studio generations are not used to train our models, only to display your personal history.

A separate, granular consent for Arena-based training is collected in the user interface in addition to these Terms.

12. Service availability, changes and beta status

  • The Service is provided on an "as is" and "as available" basis. During open beta we may introduce, modify or remove features, models, pricing tiers or limits at any time.
  • We aim for continuous availability but do not guarantee uninterrupted operation. Maintenance, third-party outages, network issues or security incidents may cause downtime.
  • We may impose reasonable technical limits (e.g. rate limits, maximum image size, generation queues) to protect the Service and other users.
  • We may update these Terms. Material changes will be announced by email and/or through the Service at least 14 days before they take effect. Continued use after the effective date constitutes acceptance. If you do not agree, stop using the Service and, where applicable, request a goodwill refund under Section 7.3.

13. Suspension and termination

We may suspend or terminate your access to the Service, with or without prior notice, if:

  • you breach these Terms or any applicable law;
  • your use creates a security, legal, reputational or financial risk for us or other users;
  • a payment is reversed, disputed or cannot be processed;
  • we are required to do so by law, court order or competent authority;
  • your account is inactive under Section 4.4.

On termination: your right to use the Service ends; unused Credits are forfeited (subject to Section 7.3 for goodwill refunds); clauses that by their nature should survive (including Sections 7, 9, 10, 11, 14, 15, 16 and 17) will survive.

You may terminate these Terms at any time by closing your account.

14. Disclaimers

To the maximum extent permitted by applicable law:

  • The Service, including all AI-generated outputs, is provided without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement or availability.
  • We do not warrant that outputs are accurate, unique, free of bias, safe for any specific use, or free from rights of third parties.
  • AI-generated images may contain artefacts, errors, unintended resemblances to real people, brands or works, or content that is not suitable for your intended use. You are solely responsible for reviewing outputs before relying on them.
  • Nothing in this Section limits rights that cannot be excluded under mandatory consumer protection law, including for consumers in the European Union.

15. Limitation of liability

To the maximum extent permitted by applicable law:

  • We are not liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of profits, revenue, data, goodwill, or business opportunities, arising out of or related to the Service.
  • Our aggregate liability to you for all claims arising out of or related to the Service in any twelve-month period is limited to the greater of (a) the amount you actually paid to us in the twelve months preceding the event giving rise to the claim, or (b) one hundred euros (EUR 100).
  • Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, for fraud, or for rights that EU consumers have under mandatory consumer protection rules.

16. Indemnification

To the extent permitted by law, you agree to indemnify and hold us harmless from claims, damages, losses and reasonable legal costs arising out of:

  • your breach of these Terms or applicable law;
  • your prompts or use of outputs (including alleged IP, privacy, publicity or defamation claims);
  • your misuse of the Service, including generating prohibited content under Section 5.

This Section does not apply to EU consumers to the extent it would conflict with mandatory consumer law.

17. Governing law and jurisdiction

17.1 Governing law

These Terms and any non-contractual obligations arising out of or in connection with them are governed by the laws of the Netherlands, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG).

17.2 Consumers in the European Union

If you are a consumer habitually resident in a Member State of the European Union, you benefit from any mandatory provisions of the law of your country of residence that cannot be derogated from by contract. The choice of Dutch law does not deprive you of such protection.

17.3 Jurisdiction

Disputes will be submitted to the competent courts of the Netherlands District Court Midden-Nederland. EU consumers may alternatively bring proceedings before the courts of their country of residence and may, where local law so provides, be sued only in those courts.

17.4 Online dispute resolution

The European Commission's Online Dispute Resolution platform is available at https://ec.europa.eu/consumers/odr. We are not obliged to participate in alternative dispute resolution proceedings before a consumer arbitration body.

18. Miscellaneous

  • Entire agreement. These Terms, together with the Privacy Policy and any pricing pages or in-product consents referenced here, form the entire agreement between you and us concerning the Service.
  • Assignment. You may not assign your rights or obligations without our prior written consent. We may assign our rights and obligations to an affiliate or a successor in the context of a reorganisation, sale of assets or similar transaction, provided your rights are not materially diminished.
  • Severability. If any provision is found unenforceable, the remaining provisions remain in full force and effect.
  • No waiver. Our failure to enforce any right under these Terms is not a waiver of that right.
  • Notices. Legal notices to us must be sent to [email protected]. Notices to you may be sent to the email associated with your account or posted in the Service.
  • Language. These Terms are concluded in English. Any translations are provided for convenience only; in case of discrepancy, the English version prevails.

If you have questions about these Terms, contact us at [email protected].
