Privacy features

It does not require any registration account, or even care to share your data to the cloud.

This app has no ads and requests no unnecessary permissions. The location permission is only needed to find a Bluetooth scale. Once found the permission can be revoked (or never granted if Bluetooth isn't used).

openScale doesn't send any data to a cloud and not having permission to access the internet is a strong guarantee of that.

If you want to synchronize your weight to GoogleFit, wger and/or MQTT 3.1, you can install openScale sync from GooglePlay.
