App: Contour - Body Tracker
Developer: Lukas Pistrol
Last updated: February 27, 2026
Contour is designed with privacy at its core. The app does not collect, transmit, or share any personal data. Everything stays on your device.
We do not collect any data.
Contour does not have servers, user accounts, analytics, or any form of data transmission. All information you enter into the app — including photos, body measurements, and weight entries — is stored exclusively on your iPhone using Apple's on-device storage.
Photos you capture within the app are stored locally in the app's private Documents directory on your device. They are:
- Never uploaded to any server
- Never shared with third parties
- Never accessible to other apps
- Deleted when you delete the app or manually remove entries
Measurements and weight data you log are stored locally using SwiftData on your device. This data is:
- Never transmitted off your device
- Not shared with Apple Health (unless you explicitly add that integration in a future update)
- Permanently deleted when you delete entries or uninstall the app
Contour does not integrate any third-party SDKs, analytics tools, advertising networks, or crash reporting services.
Since all data is stored locally on your device, you have full control over it. You can delete individual entries or all data at any time from the Settings screen within the app. Uninstalling the app removes all associated data.
Contour does not knowingly collect any information from anyone, including children under the age of 13.
If this privacy policy changes in a future update, the updated policy will be included in the app update and reflected here with a new "Last updated" date.
