All calculations are performed locally on your device. Your inputs (such as carbohydrates in grams or calories) are only kept in memory to display the result and are not stored. Once the app is closed, all inputs are gone.
No data is transmitted to third parties. The app does not connect to the internet.
The app does not request any special permissions (no access to camera, microphone, contacts, location, photos, health data, or similar).
When you download or rate the app on the Apple App Store, Apple's own privacy policy applies. The developer of this app has no influence on that processing.
This app is a learning and visualization tool for converting carbohydrates into bread units (BU/BE). It does not replace medical advice. Insulin dosing decisions should always be made together with your diabetes care team.
This policy may be updated when the app's functionality changes. The current version is always available at this URL.
