"How to auto-delete your search history
Most of Google’s new privacy controls are in a web tool called My Activity. (Here’s the URL: <a href="https://myactivity.google.com." rel="nofollow">https://myactivity.google.com.</a>)<p>Once you get into the tool and click on Activity Controls, you will see an option called Web & App Activity. Click Manage Activity and then the button under the calendar icon. Here, you can set your activity history on several Google products to automatically erase itself after three months or after 18 months. This data includes searches made on Google.com, voice requests made with Google Assistant, destinations that you looked up on Maps and searches in Google’s Play app store."
