End User License Agreement (EULA)

This End User License Agreement ("Agreement") is a legal contract between you (the "User") and Ataberk Köroğlu, a Turkish sole proprietor with VAT 5860710646, registered at Armağanevler Mah, Ümraniye, Istanbul 34760, Türkiye ("Licensor").

By downloading, installing, or using the DersTakip mobile application (the "Application"), you agree to be bound by this Agreement, the Terms & Conditions, and the Privacy Policy. If you do not agree, do not use the Application.

1. License grant

Licensor grants you a personal, limited, non-exclusive, non-transferable, revocable license to download, install, and use the Application on any device you own or control that runs Apple iOS or Google Android, in line with the usage rules of the relevant app store and this Agreement. This license is for personal, non-commercial use only.

2. Restrictions

You agree not to:

• Copy, modify, or create derivative works of the Application;
• Reverse-engineer, decompile, or disassemble the Application, except to the extent expressly permitted by applicable law;
• Rent, lease, lend, sell, sublicense, or otherwise transfer the Application;
• Remove or alter any proprietary notices, labels, or marks;
• Use the Application to develop a competing product;
• Use the Application in any way that violates the Terms & Conditions.

3. Ownership

The Application — including its source code, user interface, design, audio content, animations, and underlying curriculum/data — is and remains the property of Licensor and its licensors, and is protected by copyright, trademark, and other intellectual-property laws. No rights other than those expressly granted in this Agreement are conveyed.

4. Updates and changes

Licensor may release updates, patches, or new versions of the Application from time to time. These updates may be installed automatically by your app store. The terms of this Agreement apply to all updates unless the update is accompanied by a separate license, in which case that license applies.

Licensor may also modify, suspend, or discontinue any feature of the Application at any time. We will notify you of material changes through in-app messaging or email where reasonably possible.

5. Apple and Google store terms

The Application is distributed through Apple's App Store and Google's Play Store. Your use of the Application is also subject to the applicable store terms (Apple's Media Services Terms and Google's Play Terms of Service). Where this Agreement conflicts with the applicable store terms, the store terms prevail for that limited purpose.

Acknowledgement regarding Apple: You and Licensor acknowledge that Apple is not a party to this Agreement and is not responsible for the Application or its content. Licensor is solely responsible for the Application. Apple has no obligation to provide maintenance or support. Any product warranty claims, claims of non-conformity, third-party intellectual-property infringement claims, or product-liability claims are the responsibility of Licensor, not Apple. Apple and its subsidiaries are third-party beneficiaries of this Agreement and may enforce it against you.

6. In-app purchases and subscriptions

The Application offers an optional Premium subscription. All billing, renewals, and refunds for subscriptions and other in-app purchases are processed by the relevant app store under its terms. See our Terms & Conditions for details.

7. User data

Use of the Application involves the collection and processing of personal data as described in our Privacy Policy. By using the Application, you acknowledge and consent to such processing.

8. No warranty

The Application is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. Licensor does not warrant that the Application will be uninterrupted, secure, or error-free, or that defects will be corrected.

9. Limitation of liability

To the maximum extent permitted by law, Licensor shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, profits, or goodwill, arising from or related to your use of the Application. Licensor's total aggregate liability shall not exceed the amount you paid for the Application (including Premium subscriptions) in the 12 months preceding the claim.

10. Termination

This Agreement is effective until terminated. You may terminate it by uninstalling the Application and closing your account. Licensor may terminate this Agreement at any time if you breach any provision. Upon termination, you must stop using the Application. Provisions that by their nature should survive termination (intellectual-property, disclaimers, limitations of liability, governing law) will survive.

11. Export and sanctions compliance

You represent that you are not located in a country subject to a comprehensive Turkish, EU, UK, or US embargo, and that you are not on any government list of prohibited or restricted parties. You will not use, export, or re-export the Application in violation of applicable export-control or sanctions laws.

12. Governing law

This Agreement is governed by the laws of the Republic of Türkiye. The courts and enforcement offices of Istanbul (Anadolu) shall have exclusive jurisdiction. Consumers retain their statutory right to bring claims before consumer arbitration boards and consumer courts.
