7. Data Retention

Since all habit data is stored locally on your device, it is retained for as long as the App is installed. Subscription-related data (e.g., purchase receipts) is retained by RevenueCat for as long as required for transaction processing and fraud prevention.

8. International Users

Habit Chain is available internationally. If you are located outside Turkey, please be aware that any data processed by our third-party services (such as RevenueCat) may be transferred to and processed in countries other than your own. By using the App, you consent to such transfers as necessary to provide the service.

9. Third-Party Links

The App does not contain links to third-party websites. Any third-party services used (see Section 2b) operate under their own privacy policies.
