Everyday, there are companies out there "spying" on everyone. A little bit of a strong word but that's true. Somehow, you browse for Nike shoes for example, and the next day you get an email from Nike with their discounts on shoes. Coincidence? I don't think so. Same thing applies in applications. That's when PrivaCy was created, to stop sending unauthorized data back to bigger companies. By default, PrivaCy is disabled so go on to your Settings app.
Now enable all anonymous usage statistics.
That's it! Instead of the companies knowing who's stats come to them, they're anonymous.
It's a free tweak created by Jay Freeman (saurik) - AKA Cydia creator. You can find it in the Cydia/Telesphoreo repository. There's a very long description and backstory behind PrivaCy included, make sure you read it and undestand what it actually is.
