That is not what I am saying at all,
No matter who your cell carrier is, your whereabouts are known to them 24/7, even without an extra tracking software.
Your home computer, which is reasonably static, is probably connected to a wire that leads straight back to the offices of your Internet Service Provider, no matter who they are.
As soon as you fire up your computer they know exactly where you go and what you look at. As to your location, you are on the end of their wire!
By all means be aware of things that happen on your computer but sometimes a cigar is just a cigar.
