Around 2:50 mark, where you mentioned the story about work out. I have just one question. Could it be possible that you had GPS on and that you were seen to be at the gym (assuming your gym is registered on maps)? Since, in that case, it's easier for them to access the information and easy for the user to take some control in their hands (although there are stickers for cameras as well).
I am not trying to deny the story you said, and definitely not trying to deny the possibility to access user's cameras without their consent. But this was just a though that crossed my mind.
