This app shows you the health data already stored on your device by Health Connect. It is a viewer: it reads and it displays. The one exception is an export you start yourself.
The app has no internet permission at all. This is not a promise about how we behave — Android itself prevents the app from making any network connection. There is no server to send your data to, and no analytics, tracking or advertising code of any kind.
Only read permissions are requested, so the app cannot change or delete your health records. You choose which data types to allow, one by one, and nothing is selected by default.
Health data is held in memory only while you are looking at it, and the app never writes it to disk on its own. The only exception is an export: when you ask for one, the file is written where you choose in Android's own save dialog, and the app keeps no copy. A report you view or print goes to Android's own print preview straight from memory, and from there only where you send it. Otherwise the app keeps only your display settings. Backup and device transfer are disabled, so nothing is copied to the cloud.
Your health data is never shared with anyone, including the developer. No third-party SDKs receive it. An exported file is yours: where it goes from there is up to you.
A route is where you were during a session, the most sensitive data Health Connect holds. The app shows one only when you open that session, and only once you have allowed it, for that route or for all routes. It draws the route without a map and keeps it only while you look at it. A route leaves the app only as a GPX file you export yourself, saved where you choose.
You can withdraw access at any time in Health Connect settings. Uninstalling the app removes everything it holds, because it holds nothing beyond your settings.
Optional paid features are handled entirely by Google Play. The app never sees your payment details, and purchase checks happen through the Play Store app rather than over the network.
