Did you get the phone used? If so, did you go through a Set Up process?
If you got a used phone and did not have to do the set up, you still have the old owner's Microsoft Account in there. That gets you the Apps they paid for, but yes they can log in online and see your device location, photos, etc.
If you bought a used phone and "inherited" someone else's profile you need to change that immediately.
Settings > about > reset your phone
You will loose all data so plug into a computer and transfer over anything you want saved.
