In case you’ve ever wanted a comprehensive log of every step you’ve taken in the last day, week, month or year, Google now has you covered.

The search giant has announced a new feature for Google Maps called “Your Timeline,” which meticulously tracks and records the locations you travel with your smartphone. Pictures stored in Google Photos will also show up on the day and location they were taken.

The log could be useful for recalling a museum you visited on a vacation or a bar you stumbled into during a night out on the town, Google says in a blog post. It’s also easy to imagine way more awful ways this data could be used, but the feature is private and visible only to each specific user.

Your Timeline will be available on Android and desktop to users who have opted in to share their location history with Google (enabling this setting also improves Google Now, the company’s context-sensitive digital assistant). Visit this page to toggle the setting on or off.
