BodyMath is an offline fitness calculator (BMI, body fat, TDEE, ideal weight, water intake). No account, login, or sign-up is required. All calculations are performed on your device.## 2. Data We Collect
- Personal data on our servers: None. We do not collect, transmit, or store any personal data on our servers.
- On-device data: When you save a calculation, the inputs (e.g., height, weight, age) and the result are stored locally on your device using Android's standard app storage (AsyncStorage). This data never leaves your device and is not accessible to us.
- Advertising identifiers: BodyMath shows ads via Google AdMob. Google may collect your device's advertising ID and related data to serve ads. See Google's policy: https://policies.google.com/privacy## 3. Data Retention (How Long We Keep Your Data)
- On-device calculation history: Retained on your device indefinitely until you delete it manually, clear app storage, or uninstall the app. We do not retain any copy because the data never reaches our servers.
- Advertising data: Retained by Google AdMob per Google's retention policy, not by us.## 4. Data Deletion (How to Delete Your Data)
