The iPong privacy policy explains what happens when players choose to use local high scores and accounts.
You do not have to create an account to play. If you want to join the local iPong high-score list, an iPong account is required. Passwords are stored encrypted and SSL is used for connections.
Personal information is only used to show nicknames and names in the game and high-score list. Email is used for login identification and password reset. The app does not use cookies.
The original policy also credits the remote-controller codebase by Vivian Aranha and music used in the game.
