I think it's no surprise that our phones keep track of where we are all the time. There's GPS, and many of the apps you use collect information about what look at, click on and buy. But it turns out your iPhone itself is also hiding a list of just about every place you've ever been to.
It's called the Significant Locations list and you can find it by going through a maze of different menus.
Here's how to see it:
First, open Settings.
Next, go to Privacy.
From there, click on Location Services.
Scroll all the way down until you find System Services.
Scroll down again until you see Significant Locations.
You'll need to do Touch ID or Face ID to check out the list. Once you get through, you'll see all the cities you've ever been to, along with a list of specific locations you visited in that city along with when you were at each.
Apple assures users this information is all encrypted and that the company can't read it.
But it does raise the question of why they hid the list on the phone??
If this is something you don't want your phone to do you can turn it all off by moving the Significant Locations switch to the off position. You can also clear your Significant Locations history by selecting "Clear History" at the bottom of the list.
