Data Collection

This app does not collect, transmit, or share your personal data. All information you enter — including recipes, hydration ratios, bake notes, and photos — is stored exclusively on your device and never leaves it.

To support in-app purchases, we use RevenueCat. RevenueCat assigns an anonymous identifier to your device to manage subscription status. This identifier contains no personally identifiable information and cannot be used to identify you. RevenueCat may collect purchase-related data such as subscription status and transaction history associated with this anonymous ID. For details, see the RevenueCat Privacy Policy.

Data Deletion

If you would like to request deletion of the anonymous purchase data RevenueCat has associated with your device, visit our Data Deletion Request page.

Third Parties

Other than RevenueCat for payment processing, this app does not integrate with any third-party analytics, advertising, or data collection services.

Photos

Photos taken or selected within the app are stored locally on your device only. They are never uploaded to any server.

Children’s Privacy

This app does not knowingly collect data from children under 13. The anonymous purchase identifier described above is not linked to any personal information.
