Privacy notes

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