Google just released a new search feature that will let you review and clear your search history on your computer!
To review you history all you have to do is go to Google's menu in the top left corner and click on "Your Data in Search."
This new feature will also help you limit the ads that appear during your search settings. For example less companies would pop up about an old search in your new search for something like a pizza restaurant.
You can access the new controls on any computer and mobile phone so don't worry if you are scared if a stranger Google's something on your phone because you now have the option to protect yourself!
