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.
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.
The App does not contain links to third-party websites. Any third-party services used (see Section 2b) operate under their own privacy policies.
We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last updated" date at the top of this page. We encourage you to review this page periodically.
