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.

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.
