Google stores location data in your Google Account, which is used to create personalized experiences such as location-based reminders, predictions of estimated time to an event or location, or recommendations of nearby restaurants or stores. You can manage or delete your location data at any time.

To find and delete where Google knows you've been:

1. Go to your Google Account.

2. Under "Data & privacy", click "Location History".

3. Click the "See your Location History" button.

4. Use the map or timeline to find a location you want to delete.

5. Click on the location and select "Delete".

6. Repeat steps 4-5 for any other locations you want to delete.

You can also delete all of your location data at once by clicking the "Delete all location history" button at the bottom of the page.

*Note:* Deleting location data associated with your Google Account won't delete location data associated with other Google accounts you've signed into.
