Before you do anything on your iPhone or iPad, you should lock it down. This is how you do it.
Your apps can take a lot of liberties -- especially when it comes to your data. Some apps, like Uber, sparked controversy when they used user location at all times rather than only while they were using the app. And there was no way to turn it off.
Now, your iOS 11 device gives you more granularity to prevent this kind of constant location tracking.
Go to Settings > Privacy > Location Services, then go to any app to check its location permissions. You can now set up the Uber app so that it only collects location data when you're using it -- and no other times.
