Everyone knows your location: tracking myself down through in-app ads

Very interesting and disturbing research, definitely a wake up call for me. Does anyone know/can anyone recommend me software that can block these sorts of requests from going through? I know of pihole which blocks adds but does it also filter out these sorts of things?

You need to have a wifi only android phone, rooted, no google apps, and uninstall anything that talks to the internet. That includes analyzing network traffic, open ports, and so on.

I did this with a Kali Nethunter distro back in the day for "reasons", privacy not being one of them. This makes the phone very hard to use for regular things.

"no-root firewalls" to control data flows on devices (sorry for not publicly naming my preferred one).
