Terms of Use (EULA)

Effective date: May 12, 2026 · Last updated: May 12, 2026

These Terms of Use (the "Terms" or "EULA") govern your use of the Kniknak mobile application and the kniknak.app website (collectively, the "Service"), operated by Kniknak LLC ("we," "us," or "our"). The Service is a community for AI-generated content where you can chat with AI assistants, create images, use voice features, follow other users, and share content.

By creating an account, downloading or using the Service, you agree to these Terms. If you do not agree, do not use the Service. If you use the Service on behalf of another person, you represent that you are authorized to bind them to these Terms.

This EULA is a binding agreement between you and Kniknak LLC. Apple Inc. and Google LLC are not parties to this EULA and are not responsible for the Service or its content.

1. Eligibility

You must be at least 13 years old to use the Service (or the higher minimum age required by the laws of your country, such as 16 in parts of the European Economic Area). By using the Service, you represent and warrant that you meet the applicable minimum age and have the legal capacity to enter into these Terms.

You must also not be located in, under the control of, or a national or resident of any country subject to U.S. Government embargo, or designated by the U.S. Government as a "terrorist supporting" country, and you must not be listed on any U.S. Government list of prohibited or restricted parties (including the U.S. Treasury Department's Specially Designated Nationals list).

2. Your Account

You are responsible for your account, the credentials you use to access it, and all activity that occurs under your account. You agree to provide accurate information when creating an account and to keep it up to date. You must promptly notify us at support@kniknak.app of any unauthorized use of your account.

You may delete your account at any time from your profile settings or by emailing support@kniknak.app. We may suspend or terminate your account at any time for any reason, including violation of these Terms (see Section 11).

3. License to Use the Service

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the Service for your personal, non-commercial use, solely as permitted by these Terms and by the rules of the applicable app store.

For the Kniknak iOS app, this license is granted to you by Kniknak LLC; it is restricted to use on any Apple-branded device that you own or control, as permitted by the Apple Media Services Terms and Conditions. You may not distribute or make the Service available over a network where it could be used by multiple devices at once. You may not transfer, redistribute, or sublicense the Service.

4. Acceptable Use and Prohibited Conduct

We have zero tolerance for objectionable content or abusive users. When you use the Service, you agree NOT to:

Post objectionable content — including content that is sexually explicit, sexually exploitative (especially involving minors), violent, gory, threatening, harassing, hateful, defamatory, discriminatory, or that promotes self-harm, terrorism, or illegal activity.
Harass, bully, or threaten others — including doxxing, stalking, or coordinated harassment of any individual or group.
Use the Service to deceive — including impersonation, fraud, phishing, distributing malware, spam, or misleading AI-generated content presented as real (e.g., non-consensual deepfakes of real people).
Infringe intellectual property or privacy rights — including uploading content you do not have the right to use, or sharing another person's private information without consent.
Attempt to circumvent the Service — including reverse-engineering, decompiling, scraping at scale, bypassing rate limits, abusing the AI features, or attempting to access another user's account.
Use the Service for prohibited commercial activity — including reselling Service credits, building competing services using outputs, or using the Service to generate content that violates third-party model providers' usage policies.
Violate any applicable law — including laws relating to content, export control, sanctions, and consumer protection.

We reserve the right to remove any content and terminate any account that violates these rules, without prior notice. To report content or a user that you believe violates these rules, use the in-app report function or email support@kniknak.app. We aim to review reports within 24 hours and take appropriate action.

5. User Content

Ownership

You retain ownership of the content you create, upload, or submit to the Service (your "User Content"), including prompts you write and images you generate using the Service, subject to the rights of the underlying AI model providers and applicable law.

License you grant to us

You grant Kniknak LLC a worldwide, non-exclusive, royalty-free, sublicensable, transferable license to host, store, copy, transmit, display, reproduce, modify (e.g., resize), and distribute your User Content solely for the purpose of operating and providing the Service (including showing your public content to other users you have chosen to share with). This license ends when you delete the content, except where it has been shared with others who have not deleted it, or where we must retain it for legal reasons.

Responsibility

You are solely responsible for your User Content and for ensuring you have all rights needed to submit it. You represent that your User Content does not violate any law or third-party right.

AI outputs

AI-generated content can be inaccurate, offensive, or misleading. Outputs may resemble existing works, and the legal status of AI-generated content varies by jurisdiction. You are responsible for how you use AI outputs and for verifying their accuracy before relying on them.

6. Subscriptions, Purchases, and Auto-Renewal

How purchases are processed

Subscriptions and in-app purchases are sold and processed by Apple (via the App Store) or Google (via Google Play), and are governed by your agreement with that store. Prices and the features included in each plan are displayed in the app prior to purchase.

Auto-renewal

Subscriptions automatically renew at the end of each billing period (e.g., monthly) at the then-current price, unless you cancel at least 24 hours before the end of the current period. Your store account will be charged for renewal within 24 hours prior to the end of the current period.

Managing and canceling

You can manage and cancel subscriptions at any time in your store account settings: on iOS, Settings → your name → Subscriptions; on Android, Play Store → Profile → Payments and subscriptions → Subscriptions. Canceling stops future renewals but does not refund the current period unless required by law.

Refunds

Refunds are handled by the app store: reportaproblem.apple.com for Apple, or play.google.com for Google. Except where required by law, Kniknak LLC does not issue refunds directly.

Price changes

We may change subscription prices. If we do, we will notify you in advance and, where required by the app stores, obtain your consent before the new price takes effect.

7. Intellectual Property

The Service, including its software, design, logos, and content provided by us (excluding User Content), is owned by Kniknak LLC and our licensors and is protected by intellectual property laws. We grant you no rights in our trademarks or branding.

If you submit feedback or suggestions about the Service, you grant us a perpetual, irrevocable, royalty-free license to use them without restriction or compensation.

8. Copyright and DMCA

If you believe content on the Service infringes your copyright, send a notice that complies with the U.S. Digital Millennium Copyright Act (DMCA) to support@kniknak.app with the subject line "DMCA Notice." Your notice must include: (a) your physical or electronic signature; (b) identification of the copyrighted work claimed to have been infringed; (c) identification of the allegedly infringing material and information sufficient to locate it; (d) your contact information; (e) a statement that you have a good faith belief that the use is not authorized; and (f) a statement, under penalty of perjury, that the information is accurate and that you are authorized to act on behalf of the copyright owner.

We will respond to valid notices in accordance with the DMCA, including by removing or disabling access to the material and terminating accounts of repeat infringers.

9. Third-Party Services and AI Providers

The Service uses third-party AI model providers (currently Anthropic, OpenAI, and xAI) to power AI features. Your use of AI features may also be subject to those providers' usage policies. The Service may also include links to or features that interoperate with other third-party services. We are not responsible for those third-party services, and your use of them is at your own risk and subject to their terms.

10. Privacy

Your use of the Service is also governed by our Privacy Policy, available at kniknak.app/privacy, which describes how we collect and use personal information.

11. Termination

These Terms apply for as long as you use the Service. You may stop using the Service and delete your account at any time. We may suspend or terminate your access to the Service, in whole or in part, at any time and without notice if we believe you have violated these Terms, if doing so is necessary to protect the Service or other users, or if required by law. Upon termination, your right to use the Service ends immediately. Sections that by their nature should survive termination (including ownership, indemnity, disclaimers, liability limits, and dispute resolution) will survive.

12. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that the Service will be uninterrupted, error-free, or secure, that defects will be corrected, or that AI outputs will be accurate, appropriate, or fit for any particular purpose.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KNIKNAK LLC AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO YOUR USE OF (OR INABILITY TO USE) THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS PRECEDING THE CLAIM OR (B) USD $50.

Some jurisdictions do not allow exclusion or limitation of certain damages; in those jurisdictions, the exclusions and limitations above will apply to the maximum extent permitted by law.

14. Indemnification

To the maximum extent permitted by law, you agree to indemnify and hold harmless Kniknak LLC and its affiliates, officers, directors, employees, and agents from any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or relating to your User Content, your use of the Service, or your violation of these Terms or any law or third-party right.

15. Governing Law and Dispute Resolution

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws principles. Subject to the next paragraph, you and Kniknak LLC agree to the exclusive jurisdiction of the state and federal courts located in Delaware for any dispute arising out of or relating to these Terms or the Service.

If you reside in the European Union, the United Kingdom, or another jurisdiction that grants you the right to bring claims in your local courts under mandatory consumer protection law, nothing in these Terms limits that right.

16. Apple-Specific Terms

The following terms apply if you obtained the Kniknak app from the Apple App Store. In the event of a conflict between these Apple-specific terms and the other provisions of this EULA, the Apple-specific terms control with respect to the Apple App Store version of the app.

Acknowledgment — This EULA is between you and Kniknak LLC only, not with Apple. Apple is not responsible for the app or its content.

Warranty — Kniknak LLC is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the app to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the app (if any).

Third-Party Terms — You must comply with applicable third-party terms of agreement (e.g., your wireless data services agreement) when using the app.

17. Google Play-Specific Terms

If you obtained the Kniknak app from Google Play, you acknowledge that your use is also subject to the Google Play Terms of Service. Google is not a party to this EULA and is not responsible for the app.

18. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you through the app or by email before the changes take effect. Your continued use of the Service after the effective date constitutes your acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service.

19. General

These Terms, together with our Privacy Policy, are the entire agreement between you and Kniknak LLC regarding the Service and supersede any prior agreement on the same subject. If any provision of these Terms is found unenforceable, the remaining provisions will remain in full force. Our failure to enforce any right or provision is not a waiver of that right or provision. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets.
