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.
The only Facebook I use is a telephone book!
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
