On Facebook, deleting an app doesn't delete your data from their system
Facebook announced some intended changes to its data use policy to "enhance transparency", according to a Friday post on its Facebook and Privacy page. The updates include better explanations, examples, and "tips" denoted in the text with a lightbulb, as well as some revelations about how third parties deal with users' data.
In the revised data use policy, Facebook makes explicit that any time one of your Facebook friends starts using an app, game, or partner website (that, is a site where you can log in using Facebook credentials), Facebook hands that service all of the "publicly available" information on that user. Information that is always publicly available only includes basic stuff like your name or cover photo, but users can have their entire profile publicly available, and thus handed to a service.
However, Facebook also clarifies that "if you've removed an application and want them to delete the information you've already shared with them, you should contact the application and ask them to delete it."
