You can officially quit erasing your web history now, since Google is already saving everything you’ve ever searched for – ever. If you were logged into a Gmail or Google + account or used the Chrome browser, Google has a permanent file on you.
Go to history.google.com and your entire sordid history of searching for “brownie” recipes or naked pictures of TV actresses is displayed right before your eyes. You can even find the first thing you ever Googled!
Good news? You can erase it all and stop it from saving. Go to “Activity Controls” in your Google account and click “details.”
