Here’s how it works: Starting today, the first time you turn on Location History-which is off by default-your auto-delete option will be set to 18 months by default.
We continue to challenge ourselves to do more with less, and today we’re changing our data retention practices to make auto-delete the default for our core activity settings. That’s why last year we introduced auto-delete controls, which give you the choice to have Google automatically and continuously delete your Location History, search, voice and YouTube activity data after 3 months or 18 months. We believe that products should keep your information for only as long as it's useful and helpful to you-whether that’s being able to find your favorite destinations in Maps or getting recommendations for what to watch on YouTube.
