Welcome to Fraction Calculator & Solution. Your privacy is critically important to us. This Privacy Policy outlines how we collect, use, store, and protect your information when you use our mobile application.

1. Information We Collect & Local Storage

All calculation history, custom favorites, and user preferences (such as theme and language settings) are stored strictly locally on your device using Android Room Database and SharedPreferences. We do not collect, store, or transmit your personal calculation data to any external servers.

2. Third-Party Services & Advertising

Our app utilizes trusted third-party SDKs that may collect non-personally identifiable technical information for service delivery and analytics:

• Google AdMob: Serves banner and native advertisements within the app. AdMob may use advertising IDs and device data to serve relevant ads in accordance with Google Play policies.
• Google Play In-App Updates & UMP: Used for managing seamless app updates and European Union user consent choices.
• OneSignal: Used for optional push notifications regarding app updates and notices.

3. Permissions Used

To deliver core features and a seamless user experience, our app requests the following system permissions:

INTERNET ACCESS_NETWORK_STATE VIBRATE FOREGROUND_SERVICE

• INTERNET & ACCESS_NETWORK_STATE: Required to load banner and native advertisements, check for in-app updates via Google Play, and fetch remote support assets.
• VIBRATE: Used exclusively for tactile haptic feedback when pressing calculator buttons and toggling settings.
• FOREGROUND_SERVICE: Utilized by system components to ensure smooth background synchronization and update workflows.

4. File Import & Export

When you export or import calculation history (JSON), the app utilizes Android's system Storage Access Framework (SAF). The app only accesses files explicitly selected or created by you, with no background access to your media or file system.

5. Children's Privacy

Our application is designed for educational purposes and general audiences of all ages. We do not knowingly collect personal information from children under 13 years of age.
