These Terms may not contain usage rules that conflict with the Apple Media Services Terms of Use as of the effective date (you acknowledge that you have had the opportunity to review those terms).

4. Warranty

The Developer is solely responsible for all product warranties (express or implied by law) to the extent permitted by applicable law. If the App fails to conform to any applicable warranty, the End User may notify Apple, and Apple will refund the purchase price of the App. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the App, and all other claims, losses, liabilities, damages, costs, or expenses arising from non-conformity with any warranty are solely the Developer's responsibility.

9. Third-Party Beneficiary

You and the Developer acknowledge and agree that Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and that upon the End User's acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against the End User as a third-party beneficiary.

10. Service Description

The Terra app is a mobile application developed to inform users during earthquakes and disasters, assist with preparedness, provide rapid access in emergencies, enable location sharing, and display assembly areas.

Earthquake data is sourced from AFAD (Disaster and Emergency Management Presidency), Kandilli Observatory and Earthquake Research Institute (Boğaziçi University), and USGS (United States Geological Survey).

This app is not affiliated with any official institution (AFAD, Kandilli, etc.) and is for informational purposes only. Terra is not an official earthquake warning system.

11. Technical Requirements

Required permissions for earthquake notifications, location services, and emergency features must be granted.

Because earthquake data is obtained from third-party sources, the app requires an internet connection.
