Does the NSA know when you walk around the block? Of course they don’t but Google does and it keeps records of your walks forever. Not only that, it develops algorithms that examine where you walk, what businesses you might be visiting and profiles your speed, how long your rests are and estimates your personal fitness.
Why do they do that? You don’t want to know, I can assure you that.
Of course Google tracks every internet search you do. Every time you type into a search box, they record it, place that into an algorithm and enhance their personal profile of you. What do you type into search boxes? Do you even remember? Have you ever let your curiosity get the best of you and peek at things that might give the wrong impression? Well those things are now part of your personality inventory by Google, a profile of physical and mental health, sexual proclivities, shopping needs, religious and political beliefs. It actually goes much further than this.
The NSA does none of this.
Ever use Google Location Services when you are driving. Most phones have this and with my phone, it turns itself on against my wishes all the time, sometimes several times a day. This allows Google to see not only where you walk, even inside your own home if you keep your phone with you (like how often you go to the bathroom and based on how long you are there, what you do).
When you drive, you are tracked as well, how fast you drive, where you go, when you stop your car. They see you when you get your oil changed, they see you when you check into a motel, they see you at the liquor store and when you buy drugs.
They know how often you visit your mother, when you pick your kids up from school, the routes you drive and, of course, your political views, your associations, what you buy online, guns, ammo, pet food, they know it all.
And people worry about the NSA.
