Google is adding new protections for your search history like quick deletion, requiring verification to access the My Activity section, and more.
You can also try out a new way to quickly delete your last 15 minutes of saved Search history with the single tap of a button. This feature is available in the Google app for iOS, and is coming to the Android Google app later this year.
You could also just turn disable your search history altogether, too.
