You stay the sole\nowner of your data: there is no central server and the developer stores nothing.\n\nRequirements:\n\n* Android 14 or newer. Cairn reads through Health Connect, which is part of the\n  system only from Android 14; on Android 8-13 it is a separate Google app from\n  the Play Store, which a Play-less device cannot install — so the app would\n  find nothing to read.\n* A Nextcloud of your own is optional: without one, Cairn still reads and shows\n  your data, it just keeps the files on the phone.\n\nFeatures:\n\n* Reads heart rate, steps, body weight, sleep and workouts — read-only. Cairn\n  never writes to your health store.\n* Syncs the files to your own Nextcloud over WebDAV, with optional background\n  sync.\n* In-app dashboard with a sleep-stage deep-dive and a BMI computed from your\n  latest weight.\n* Available in English and German.\n\nPrivacy:\n\n* No advertising, no analytics, no trackers, no third-party services.\n* Your data lives only on your device and in the Nextcloud you control — never\n  in any developer or third-party cloud.\n* HTTPS only. The Nextcloud app password is stored in the operating system's\n  secure storage and can be revoked at any time.\n\nCairn is an aggregator and viewer, not a medical device. It makes no diagnostic\nor treatment claims.\n","categories":["Sports & Health"]}
