DIY Formula Handbook ("the App") respects and protects your privacy. This policy explains how we collect, use, and protect your information.
1. Data Storage
Coin balance, unlock records, favorites, custom recipes, and purchase history are stored on your device. We do not upload this data to our servers.
2. In-App Purchases
Purchases are processed by Apple. We do not access your payment card details. The App only records transaction IDs, product types, purchase time, and coin amounts to grant coins and show purchase history.
3. Notifications
If you enable daily check-in reminders, the App uses local notifications only and does not collect personal identity information.
4. Data Deletion
Uninstalling the App removes on-device data. In-app purchase records remain managed by your Apple account.
5. Children's Privacy
The App does not knowingly collect information from children under 13.
6. Policy Updates
We may update this policy from time to time. Updated versions will be published in the App.
7. Contact
For privacy questions, contact the developer via the App Store listing.
