Update:
1) Google collects your location with Android, even if you disabled it in the system settings;
2) Facebook (and Google) access to your contacts and use it to make networks;
3) you may give granular permissions to Facebook and Google by rooting your phone and installing a ROM such as Lineage OS or Replicant; and
4) in my country, France, the law allows me to ask them to delete anything I want.

I'm interested about what is done in Lineage : even without Gapps,Google still have access to location ?
@fluffy I don't know. I'm not into Android ROMs.
I'd suggest people to use ROMs from trusted actors rather than the fancy ones: Fairphone, Replicant…
@wire
Yeah, I would trust Replicant a lot more. :-/ also I would like to learn.how to build Roms, to deactivate some things maybe.
