iPhone's 'Frequent Locations' Feature Raises Privacy Concerns

What if someone had a list of every place you go, along with the exact time you arrive and leave each day? It turns out that information is on many of our phones.

We're talking about the "frequent locations" feature on your phone. If you ask most people about it, they don't know what it is or how to get there. But once they do, they're shocked at what they find.

To their surprise, there's a list of every place they've been with their phone. It even labels your assumed home and work addresses based on the amount of time you spend there.

Privacy experts say they've been concerned for a long time about the implications of this hidden information.

"This could be used by abusive partners. It could be used by police in an investigation. It could be used by your boss or your company if you gave them access to your phone or if you're using a work phone," said Noah Swartz/Electronic Frontier Foundation.

Apple says the data is stored only on your device unless you've selected "Opt In To Improve Maps." Then, Apple stores your information anonymously. You can delete the locations by tapping "Clear History" in your privacy settings.

Apple says "Frequent Locations" are meant to provide you with personalized services, like predictive traffic routing.
