Google Activity History is sort of terrifying but also great. I used it when someone stole my laptop to learn that the thief had googled pawn shops in the area; I contacted one of the pawn shops they looked up and a bit later they called me telling me someone had brought in a laptop matching my description. They lied to her and told her they needed to process the laptop for a few hours and she needed to come back, and in that time the police were called, she was arrested, and I got my laptop back the same day it was stolen.
