Pixel phone privacy. How to exempt data sharing with google Does anybody knows if a pixel phone is able to profile, based on the user's data although a VPN is always active on the phone.
I am also not using any Google apps. I am wondering if the profiling is done on the mobile platform, then sent to Google's profiling analysis servers.
You will need to install another ROM that does not have Google Play services such as LineageOS or GrapheneOS.

I am also not using any Google apps.

It does not matter which Google apps you explicitly use or not, this process is a core part of stock Android.

VPN is always active on the phone

This cannot be guaranteed unless the phone is rooted as some connections might be made before the VPN is setup.
