Ondra

Privacy policy

Ondra stores your contraction timings and optional care contact details on your device. The developer does not receive this information.

No account, advertising, analytics, tracking, or third-party SDKs are included. Ondra does not access HealthKit, your address book, location, microphone, or camera.

Contraction start and end times, a running timer’s start time, and the session start time are saved in the app’s private storage. Pattern feedback is calculated on your device.

Your optional care team name and working-hours and after-hours phone numbers are saved in the app’s preferences.

Timing files use iOS file protection and are excluded from device backups. Care contact preferences may be included in backups managed by iOS. Ondra does not provide its own cloud storage or syncing.

Timings leave the app only when you choose to share them. The destination app or service then handles the information under its own privacy policy.

Tapping a call button passes the number to the system calling service. Ondra never calls automatically. Opening a medical reference takes you to an external website, whose privacy policy applies.

Your current session remains until you delete entries or start a new session in History. You can clear care contact fields at any time. Starting a new session does not clear your care contact.

If a timing file cannot be read, Ondra preserves it on the device for possible recovery. Deleting the app, rather than offloading it, removes its local files and preferences. Copies you shared or saved in system backups are managed separately.
