Title + As I dont have a G account signed in they cant track me as a person and I also turned diagnostics data sharing off. Will it be help they might track me a as person on this device.Right?? Also as to quit google I have to quit internet so will it be advantageous to do this thing.
i used this once https://play.google.com/store/apps/details?id=dnsfilter.android . there are similar apps. they can block a lot, but it will lead to things not working, for example push notifications probably won't work, if you block firebase servers.
