This Privacy Policy explains how FractionSolver handles user information.
1. Local-first calculation data
FractionSolver stores preferences and recent solution history locally on your device, including:
- Language, appearance, and solution-style preferences
- Teaching-hint visibility
- Recent solved problems (expression, steps, and answer)
FractionSolver does not require an account. All fraction calculation is performed on-device and works fully offline.
2. No tracking or advertising
FractionSolver does not include advertising SDKs, third-party analytics trackers, or cross-app tracking. FractionSolver does not sell user data.
3. StoreKit and purchases
- FractionSolver uses Apple StoreKit for the optional Premium (lifetime) purchase
- Billing, refunds, cancellation, and purchase history are handled by Apple
- FractionSolver reads entitlement status needed to unlock Premium features
- FractionSolver does not have access to your Apple ID password, payment method, or full Apple transaction history
4. Device permissions
The current FractionSolver app does not require location, camera, microphone, contacts, photo library, health, or Bluetooth permissions.
5. Data deletion
You can remove local FractionSolver data by deleting the app from your device. Apple platform behavior may retain purchase records for your Apple ID so purchases can be restored.
6. Children's privacy
FractionSolver is designed for students, parents, and teachers and does not include account registration, chat, user-generated content, advertising, or tracking. Parents can use Apple Screen Time, purchase restrictions, and App Store family controls to manage access and purchases.
