If you want to have your Google data evaporate to preserve privacy, read How to Set Your Google Data to Self-Destruct I stopped using Google awhile ago in favor of DuckDuckGo precisely because of data tracking concerns.

I logged in at the posted URL, and all I saw was "No Activity," I suppose because I NEVER log in to Google.

If you don't have a Google account, so you can't log in in the first place, does that mean you have "No Activity", too?

It may be paranoia, but I assume that Google (and, for that matter, Facebook) keeps a dossier of activity emanating from my ISP address, but it's not specifically tied to me as an individual.

Maybe it's because of AdBlock For Safari, but I never see targeted ads; I do, however, get search results that appear to take my ISP address into consideration.

And I"m not the least bit certain that that makes the least bit of sense.
