2. Information We Collect

Zero Personal Identifiable Data: FreeCalc does not collect, transmit, sell, or store any personal data such as your name, email, phone number, contacts, or location. All your calculation history, saved presets, and theme settings reside exclusively on your local device sandbox (`SharedPreferences`).

3. Device Permissions

FreeCalc requests minimal Android system permissions strictly for feature functionality:

  • INTERNET / ACCESS_NETWORK_STATE: Required to fetch live currency conversion rates from the European Central Bank (ECB) and handle Google Play billing status.
  • VIBRATION: Provides subtle haptic feedback when pressing keys (toggleable in Settings).

4. In-App Purchases & Billing

FreeCalc offers optional premium subscriptions and one-time lifetime purchases to remove advertisements. All payments are handled securely by Google Play Billing APIs. We never store or access your credit card or financial details.

5. Third-Party Services

FreeCalc uses official Google libraries:

  • Google Play Services: Used for app distribution, updates, and in-app purchase validation.
  • Google AdMob: Serves non-intrusive ads in the free version of the app. AdMob may process anonymized advertising IDs in accordance with Google's Privacy Policy.
