The telemetry is documented in detail at https://github.com/mozilla-mobile/focus-android/wiki/Telemet...
We also include Adjust in Focus (not in Klar) for attribution tracking - to understand where the install came from. (This is useful if you are spending money on campaigns and you would like to understand what campaigns are the most effective)
If you have questions or suggestions, check the https://github.com/mozilla-mobile/focus-android/blob/master/... for ways to reach the team.
