Cairn ذہنی صحت ایپ کے لئے Android وضاحت
Cairn reads your health and fitness data from the phones health store — Apple Health on iOS, Health Connect on Android — and saves it as plain, open-format files (Open mHealth / IEEE 1752.1 JSON) in your own Nextcloud. You stay the sole owner of your data: there is no central server and the developer stores nothing.
Requirements:
- Android 14 or newer. Cairn reads through Health Connect, which is part of the system only from Android 14; on Android 8-13 it is a separate Google app from the Play Store, which a Play-less device cannot install — so the app would find nothing to read.
- A Nextcloud of your own is optional: without one, Cairn still reads and shows your data, it just keeps the files on the phone.
Features:
- Reads heart rate, steps, body weight, sleep and workouts — read-only. Cairn never writes to your health store.
- Syncs the files to your own Nextcloud over WebDAV, with optional background sync.
- In-app dashboard with a sleep-stage deep-dive and a BMI computed from your latest weight.
- Available in English and German.
Privacy:
- No advertising, no analytics, no trackers, no third-party services.
- Your data lives only on your device and in the Nextcloud you control — never in any developer or third-party cloud.
- HTTPS only. The Nextcloud app password is stored in the operating systems secure storage and can be revoked at any time.
Cairn is an aggregator and viewer, not a medical device. It makes no diagnostic or treatment claims.
