Correct @missioncontrol, thanks a lot for your comment!
You can indeed disable a lot if you know how and where.
On the other hand, I e.g. disabled the voice recording (hopefully I find the time to post part 2 today with the information) but suddenly it was on again.
Also the "sending a copy of our data" will be addressed in my part 2 of this post. Can be some GB to download actually.
I'm pretty sure many people do not even know about the links and where to do the settings and download collected their data. This I wanted to show here ...

Steem on!
