Please understandnim asking this question from a genuine place. I dont want the quora answer, i want the tech savvy, security expert minds of my fellow lemmings. If thats ok?
What happens to this data? What can/do they do with it? and why are so many people concerned about google tracking them?
Do i as an average user need to be concerned?
If so, What sorts of things can i do to avoid being tracked? Preferably without too much comprimise.
I just don’t use the internet, can’t track me if I ain’t on it!
If your friends have Facebook, and they share contacts on their phone, and they communicate with you Facebook has a shadow profile for your phone number. They still track you even without the app or an account.
