We’ll also share all of this information with the government. We’re just suckers for guys with crew cuts carrying subpoenas.
Remember, when you visit our Web site, our Web site is also visiting you. And we’ve brought a dozen or more friends with us, depending on how many ad networks and third-party data services we use. We’re not going to tell which ones, though you could probably figure this out by carefully watching the different URLs that flash across the bottom of your browser as each page loads or when you mouse over various bits. It’s not like you’ve got better things to do.
Each of these sites may leave behind a little gift known as a cookie -- a text file filled with inscrutable gibberish that allows various computers around the globe to identify you, including your preferences, browser settings, which parts of the site you visited, which ads you clicked on, and whether you actually purchased something.
Those same cookies may let our advertising and data broker partners track you across every other site you visit, then dump all of your information into a huge database attached to a unique ID number, which they may sell ad infinitum without ever notifying you or asking for permission.
Also: We collect your IP address, which might change every time you log on but probably doesn’t. At the very least, your IP address tells us the name of your ISP and the city where you live; with a legal court order, it can also give us your name and billing address (see guys with crew cuts and subpoenas, above).
Besides your IP, we record some specifics about your operating system and browser. Amazingly, this information (known as your user agent string) can be enough to narrow you down to one of a few hundred people on the Webbernets, all by its lonesome. Isn’t technology wonderful?
We store this information an indefinite amount of time for reasons even we don’t fully understand. And when we do eventually get around to deleting it, you can bet it’s still kicking around on some network backup drives in somebody’s closet. So once we have it, there’s really no getting it back. Hell, we can’t even find our keys half the time -- how do you expect us to keep track of this stuff?
