Launch the Google Chrome Browser. Go to myactivity.google.com.
Click the menu button. And then select “Delete Activity By.”
There should be some text visible that says “Delete Activity”. Below that should be an option “All Time”. Choose “All Time.”
As always, from the next screen choose “Select All.” But only choosing specific apps and services that may have too much personal data is also fine.
Click the “Next” button.
Then click the “Delete” button.
