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.
If you want both privacy and security you may want to have a look at these links:
1) Blackphone: https://www.styxblackphone.com/buy-blackphone
2) BSD-based secure phone: https://hackaday.io/project/13145-bsd-based-secure-smartphone
@alfajet Yes, you're right. My mistake.
The BSD-based phone will also rely on Google voice but I should hopefully contain it within a bhyve container.
@wire no need to apologise ;)
It was interesting to see this. I just worry that these guys might just want to follow the trend on privacy concerns in order to position their product as opposed to genuinely be sensitive to these issues.
I might be wrong though, it's just based on their screenshots. Maybe they have good intentions but imo, they should sever completely their links to Google to be credible.
