Welcome to Fraction Plus. This Privacy Policy describes how we handle information in connection with your use of the Fraction Plus mobile application ("Application", "App", "Service"). We are committed to protecting your privacy and ensuring a transparent user experience.

1. Information We Collect and Storage

Fraction Plus is designed as an offline-capable utility. We do not require account registration, personal profile creation, or user sign-in to use the core features of the application.

• Local Calculation History: All calculations, fraction inputs, step-by-step solutions, and favorited records are stored locally on your device using a local database (Room). This data never leaves your device unless you explicitly choose to export or share it.
• User Preferences: App preferences, such as selected theme mode, app language, decimal precision, and haptic feedback settings, are saved locally on your device.
• Automatically Processed Technical Data: To ensure proper app performance, maintenance checks, and ad delivery, basic non-personally identifiable technical information (e.g., operating system version, app package name, device model, and IP address) may be processed by integrated third-party services.

2. Android App Permissions Used

Fraction Plus requests minimal Android system permissions strictly necessary to provide its features:

• android.permission.INTERNET: Required for checking app maintenance status updates, serving advertisements via Google AdMob, and receiving app notification channels.

AdMob may use Advertising Identifiers (AAID), IP address, and technical device diagnostics to deliver contextual or personalized ads according to Google's Privacy Policy . You can manage ad personalization through your Android device settings.

• Deleting History: You can clear individual history records or wipe all stored calculations at any time from the History screen.
• App Uninstall: Uninstalling the application removes all locally stored application data and preferences from your device.

5. Children's Privacy

Fraction Plus is an educational fraction calculator and math learning tool appropriate for general audiences, including students. We strictly adhere to child privacy protection standards:

• We do not knowingly collect, solicit, or request personally identifiable information (PII) from children under 13 years of age (or the applicable age limit in your jurisdiction).
• If a parent or guardian becomes aware that their child has provided us with personal information without consent, please contact us immediately, and we will take prompt action to remove such information.
