Violation of this section may result in immediate suspension or termination without refund.

8. User-Generated Content (UGC)

8.1 Your Ownership

You retain all rights you have in the UGC you create through the Service, including generated Guides and your edits. We do not claim ownership of your UGC.

8.2 License to Provider

You grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (e.g., format conversion for sync), and transmit your UGC solely for the purpose of operating, providing, and maintaining the Service for you (including backup, sync, and AI-powered features you request). This license terminates when you delete the UGC or your account, except for residual backup copies retained as described in our Privacy Policy.

8.3 Your Warranties

You represent and warrant that:

• You own or have all necessary rights to submit the content you process through the Service.
• Your UGC does not infringe any third-party intellectual property, privacy, or publicity rights.
• Your use of the Service, including processing content from Third-Party Platforms, complies with those platforms' terms of service.
• Your UGC does not violate any applicable law or these Terms.

9. Third-Party Platform Content

VYK does not host, mirror, or redistribute the original video, audio, or image content you submit from Third-Party Platforms. We transiently process that content solely to generate a Guide for your personal use. You are solely responsible for ensuring that your submission and processing of such content complies with the terms of service, copyright policies, and other rules of the originating platform. You represent that your use constitutes fair use, personal backup, or is otherwise authorized.

10. Intellectual Property

The Service (including its software, design, logo, branding, and all text, graphics, and arrangements therein) is owned by the Provider and protected by Turkish and international copyright, trademark, patent, trade secret, and other intellectual property laws. Except for the limited license in Section 5, no rights are granted to you in the Service.

11. Copyright Infringement & Takedown

We respect intellectual property rights. If you believe content processed through or stored via the Service infringes your copyright or other IP rights, send us a written notice to hello@vyk.app containing:

• Identification of the work you claim is infringed.
• Identification of the allegedly infringing material with enough detail to locate it (e.g., user ID, guide ID, URL submitted).
• Your contact information (name, address, email, phone).
• A good-faith statement that the disputed use is not authorized by you, your agent, or the law.
• A statement under penalty of perjury that the information is accurate and that you are the rights holder or authorized to act on their behalf.
• Your physical or electronic signature.

Upon receiving a valid notice, we will take appropriate action, which may include removing the material and, for repeat infringers, terminating the offending account.

12. Subscriptions, Purchases & Free Tier

12.1 Free Tier

The Service offers a free tier with usage limits (e.g., number of guide generations per period) displayed in the App. Limits may change with reasonable notice. Free tier features may exclude Pro capabilities such as AI Chat, priority processing, natural voice reading, and higher quotas.

12.2 Pro Subscription & Billing

Pro Subscriptions are processed exclusively through the App Store from which you downloaded the Service. By subscribing, you authorize the App Store to charge your registered payment method the total price, including any taxes, at the start of each billing period.

12.3 Auto-Renewal

Subscriptions automatically renew at the end of each billing period at the then-current price unless cancelled at least 24 hours before the end of the current period through your App Store account settings. Uninstalling the App does not cancel your Subscription.

12.4 Free Trials

We may, at our discretion, offer promotional free trials. Unless you cancel before the trial ends, you will be automatically enrolled and charged for the Subscription at the standard price. It is your responsibility to track the trial end date; we do not guarantee reminder notifications.

12.5 Price Changes

We reserve the right to change Subscription pricing. For ongoing Subscriptions, we will provide reasonable prior notice. If you do not agree, your sole remedy is to cancel before the change takes effect. Continued use constitutes acceptance of the new price.

12.6 Refunds

Except where required by law, all purchases are final and non-refundable. Refund requests must be submitted to the App Store (Apple or Google) directly; we do not have the technical ability to issue refunds for App Store purchases.

12.7 Restore Purchases

If you reinstall the App or switch devices, you can restore active Subscriptions and non-consumable purchases via the "Restore Purchases" option in the App, subject to App Store capabilities.

12.8 Non-Payment

If the App Store cannot process payment, we may suspend or terminate your Pro access without notice.

13. AI-Specific Disclaimer

The Service uses artificial intelligence (Google Gemini, OpenAI) to generate content. AI systems can produce inaccurate, incomplete, biased, or misleading output, commonly known as "hallucinations." By using the Service, you acknowledge that:

• Guides, summaries, and chat responses are generated automatically and may contain errors.
• You must independently verify any critical information, especially in sensitive domains.
• The Service does not provide medical, legal, financial, nutritional, safety, or other professional advice. Output is for informational and entertainment purposes only.
• You are solely responsible for decisions and actions taken based on AI-generated content.

We disclaim all liability for damages, losses, or injuries arising from reliance on AI-generated content.

14. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION. WE DO NOT WARRANT THAT THE SERVICE WILL BE ERROR-FREE, SECURE, OR FREE FROM HARMFUL COMPONENTS. YOUR USE OF THE SERVICE IS AT YOUR SOLE RISK.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL THE PROVIDER BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR SUBSTITUTE SERVICES, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN ANY CASE, OUR AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM OR (B) USD $50. Some jurisdictions do not allow exclusion of certain damages; these limits apply to the maximum extent permitted by law.

16. Indemnification

You agree to indemnify, defend, and hold harmless the Provider and its agents from any claims, damages, liabilities, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Service; (b) your breach of these Terms; (c) your UGC or content you submit for processing; (d) your violation of any third party's rights, including the terms of service of any Third-Party Platform; or (e) your violation of any applicable law. We reserve the right to assume the exclusive defense of any matter, at your expense, for which you are required to indemnify us.

17. Data & Privacy

Our collection, use, and protection of your personal data is described in our Privacy Policy, which is incorporated by reference. You remain responsible for the accuracy of the data you provide and for maintaining backups where feasible. We do not guarantee that Service data will always be available or error-free.

18. Third-Party Services

The Service integrates with or relies on third-party services including Firebase, RevenueCat, Sentry, Google Gemini, OpenAI, App Stores, and Third-Party Platforms whose URLs you submit. We do not own or control these services. Your use is governed by their respective terms and privacy policies. We are not responsible for their content, availability, or practices.

19. Modifications to the Service & Terms

We may modify, suspend, or discontinue the Service (or any part thereof) at any time, with or without notice. We may also revise these Terms. Material changes will be notified via the App, email, or our website prior to taking effect. The "Last updated" date indicates the latest revision. Continued use after changes constitutes acceptance. If you disagree, you must stop using the Service.

20. Termination

20.1 By You

You may stop using the Service at any time by uninstalling the App and/or deleting your account from in-app settings or by emailing hello@vyk.app. Cancel Subscriptions through your App Store.

20.2 By Us

We may suspend or terminate your access, with or without notice, for breach of these Terms, violation of law, suspected fraud, non-payment, to protect the Service or other users, or upon discontinuation of the Service.

20.3 Effect

Upon termination, your right to use the Service ceases immediately. Account data may be deleted subject to our Privacy Policy and legal retention obligations. Termination does not entitle you to refunds except as required by law.

20.4 Survival

Sections 2 (Definitions), 7 (Prohibited Conduct), 8.2–8.3 (UGC license & warranties), 10 (IP), 13 (AI Disclaimer), 14 (Warranties), 15 (Liability), 16 (Indemnification), 21–27 (Governing Law, Dispute Resolution, Misc.), and any other provisions that by their nature should survive will remain in effect after termination.

21. Governing Law & Jurisdiction

These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes) are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws provisions. The courts and enforcement offices of Ankara, Türkiye shall have exclusive jurisdiction over any disputes. Nothing in this section limits consumer rights guaranteed by the mandatory laws of your country of residence.

22. Dispute Resolution

Before filing any claim, you agree to first attempt to resolve the dispute by contacting us at hello@vyk.app. If no resolution is reached within thirty (30) days of your written notice, either party may pursue the dispute in the courts specified in Section 21.

23. Force Majeure

We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, natural disasters, war, terrorism, pandemics, government actions, power or network failures, third-party service outages, or labor disputes.

24. Severability & No Waiver

If any provision of these Terms is found invalid or unenforceable, the remaining provisions will remain in full force. Our failure to enforce any right or provision is not a waiver of that right.

25. Assignment

You may not assign or transfer your rights under these Terms without our prior written consent. We may assign our rights and obligations to any successor in connection with a merger, acquisition, or asset transfer, or to an affiliate or subcontractor, without notice.

26. Notices

We may provide notices to you via in-app messages, email to your registered address, or postings on our website. Notices are deemed received when first made available. Notices to us must be sent to hello@vyk.app or by post to the address in Section 1.

27. Entire Agreement

These Terms, together with the Privacy Policy and any additional terms published within the Service, constitute the entire agreement between you and us regarding the Service, superseding any prior agreements.

28. Apple & Google Specific Terms

If you downloaded the App from the Apple App Store, you acknowledge that these Terms are between you and the Provider only — not with Apple. Apple is not responsible for the App or its content. Apple's Standard EULA applies to the extent it is not superseded by these Terms. Apple and its subsidiaries are third-party beneficiaries of these Terms and have the right to enforce them against you.

If you downloaded the App from the Google Play Store, Google's terms also apply where not superseded by these Terms.
