From Kim Komando today:
"Google always tracks your location even when you tell it not to. It's no secret that Google monitors and stores a lot of information about you, such as your location history. In other words, you have to be comfortable with Google knowing where you are if you want it to help without you asking. Google does provide tools and options to turn location tracking off, however, new findings indicate that Google still records your movements even when you tell it not to. Now, that's creepy."
