HealthBridge – Privacy Policy

Effective date: 22 October 2026

HealthBridge (package app.hwbridge.health) is an Android app built by an individual developer for personal use. It copies the user's own health data from HUAWEI Health Kit into Google Health Connect on the same phone. This policy explains which data the app accesses and how it is handled.

1. Data the app accesses

After the user signs in with their HUAWEI ID and grants consent, the app reads the following data from HUAWEI Health Kit, read-only:

steps, distance and calories
heart rate and resting heart rate
blood oxygen saturation (SpO2)
body weight
sleep sessions and sleep stages
workout (activity) records

The app does not access contacts, location, photos, advertising identifiers or any data not listed above.

2. How the data is used

The data is used for one purpose only: writing it into Google Health Connect on the user's own device, so that the user can see it in other health apps they choose. The app does not analyse, profile or display the data beyond a short sync log on the device.

3. Where the data goes

Data travels only from the HUAWEI Health Kit cloud API to the user's phone over HTTPS.
The app has no server of its own. No health data is uploaded, stored or processed anywhere other than on the user's device.
Data obtained from HUAWEI Health Kit is never sold, shared with third parties, used for advertising or used to train any model.
Once written to Health Connect, data is governed by Health Connect and by the permissions the user grants to other apps there.

4. Data stored on the device

The app stores in its private storage only: the OAuth tokens needed to access HUAWEI Health Kit, the time of the last sync and a short text log of recent syncs. Backups of this storage are disabled. All of it is deleted when the app is uninstalled.

5. User control

The user can stop syncing at any time by turning off automatic sync in the app.
Access to HUAWEI Health Kit can be revoked at any time from the HUAWEI ID account settings or from the HUAWEI Health app (Privacy management).
Data written to Health Connect can be viewed and deleted from the Health Connect settings on the phone.
Uninstalling the app removes all data stored by the app itself.

6. Security

All network communication uses HTTPS. Tokens are kept in the app's private storage, which other apps cannot access.

7. Children

The app is not intended for children and is not distributed publicly.

8. Changes

If this policy changes, the new version will be published at this address with a new effective date.
