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.

      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.

        You’re not even safe from deleting your account.

        You delete your account, come back with a new one to find that the suggested people are people you once had as friends or looked at.

        Gee, wonder how they know that? /s
