Google Maps is making a big privacy change to protect your location history

Google Maps is changing the way it handles your location data. Instead of backing up your data to the cloud, Google will soon store it locally on your device.

In an email sent to users, Google says you have until December 1st to save all your travels to your mobile device before it starts deleting your old data. Timeline — previously known as Location History — is the feature that tracks your routes and trips based on your phone’s location, allowing you to revisit all the places you’ve been in the past.

The transition to on-device storage also means that you’ll no longer be able to access your Timeline from the web in December. If you don’t enable the new Timeline settings by then, Google will attempt to move the past 90 days of your travel history to the first device you sign in to Google on. The company will then delete any data older than that.

If you want to keep using Timeline, open Google Maps on your mobile device, click on your profile picture in the top-right corner of the screen, and choose Your Timeline. From there, select whether to keep you want to keep your location data until you manually delete it or have Google auto-delete it after three, 18, or 36 months. Google will store the information you want to keep on your device.
