Google wasn't the first search engine to take the human interaction out of that process, it was just the best at finding the information you were looking for. And as long as you were sure to delete your search history afterwards, you could read up on any kind of fucked up, degenerate behavior you wanted without another human soul ever knowing.
It turns out, Google records everything you enter into its search engine. The lonely night a few months back when you Googled "how many fists can fit in the butt?" That's stored on Google's servers, correlated with your IP address and a pretty shocking amount of other personal information.
We never knew how far this would go.
But they're not just passively stalking you via your weird ass searches. If you use Google to help you navigate the Web, there's a good chance they've installed a cookie onto your browser that logs every page you visit, every form you fill out and every conversation you have. Google sees it all and stores it for at least nine months.
Consumer advocate group Privacy International says nine months is the best case scenario. Even if you only use a few of Google's free services, "the company retains a large quantity of information about that user, often for an unstated or indefinite length of time, without clear limitation on subsequent use."
