Oops: Google says it might have deleted your Maps Timeline data

The Google Maps Timeline has long been a useful though slightly uncomfortable feature that maintains a complete record of everywhere your phone goes (and probably you with it). Google recently changed the way it stored timeline data to improve privacy, but the company now confirms that a “technical issue” resulted in many users losing their timeline history altogether, and there might not be any way to recover it.

Timeline, previously known as Location History, is very useful if you need to figure out where you were on a particular day or if you just can’t remember where you found that neat bar on your last vacation. Many Google users grew quite fond of having access to that data. However, Google had access to it, too. Starting in 2024, Google transitioned to storing Timeline data only on the user’s individual smartphone instead of backing it up to the cloud. You can probably see where this is going.

Users started piping up over the past several weeks, posting on the Google support forums, Reddit, and other social media that their treasured Timeline data had gone missing. Google has been investigating the problem, and the news isn’t good. In an email sent out over the weekend, Google confirmed what many already feared: Maps has accidentally deleted Timeline data on countless devices.

A Google spokesperson confirmed this is the result of a technical issue and not user error or an intentional change. It’s unclear how this happened, but we’d wager on a botched Maps update. Google usually rolls out updates in waves, and it’s possible that the defective build in this case made it to a large number of devices before it was stopped.

You have exactly one possible fix for this issue, but only if you planned ahead. When Google began the full change-over to local storage of Timeline data, it added several settings to control the feature. While the data is stored locally by default, you have the option of creating encrypted backups in the cloud. If you did that, you should be able to restore the data.

Both operating systems will display a list of apps and whether they are permitted access always, never, only while the app is in use, or to prompt for permission each time. Both also allow users to choose whether the app sees precise locations down to a few feet or only a coarse-grained location.

For most users, there’s usefulness in allowing an app for photos, transit or maps to access a user’s precise location. For other classes of apps—say those for Internet jukeboxes at bars and restaurants—it can be helpful for them to have an approximate location, but giving them precise, fine-grained access is likely overkill. And for other apps, there’s no reason for them ever to know the device’s location. With a few exceptions, there’s little reason for apps to always have location access.

Not surprisingly, Android users who want to block intrusive location gathering have more settings to change than iOS users. The first thing to do is access Settings > Security & Privacy > Ads and choose “Delete advertising ID.” Then, promptly ignore the long, scary warning Google provides and hit the button confirming the decision at the bottom. If you don’t see that setting, good for you. It means you already deleted it. Google provides documentation here.

iOS, by default, doesn’t give apps access to “Identifier for Advertisers,” Apple’s version of the unique tracking number assigned to iPhones, iPads, and AppleTVs. Apps, however, can display a window asking that the setting be turned on, so it’s useful to check. iPhone users can do this by accessing Settings > Privacy & Security > Tracking. Any apps with permission to access the unique ID will appear. While there, users should also turn off the “Allow Apps to Request to Track” button. While in iOS Privacy & Security, users should navigate to Apple Advertising and ensure Personalized Ads is turned off.
