As most of you already know, Google keeps a tab on
pretty much everything
you do on a Google site, provided that you signed in on any one of these
websites. Everything you do is recorded, and can be used against you in
the future. Search data can reveal particularly sensitive information about you, such as facts about your location, interests, age, religious views, and so on. You can, however, choose to not be so vulnerable, and can remove all of your Google web history to
protect yourself from an unforeseen eventuality.
