Privacy protection

We're only saving the data which is absolutely necessary, regardless of the freeware or Steam version. The game is only connecting to the server if one logs in or reaches a new highscore. The score will be saved into a database. We don't save how often you play. We will not know how many times you tried a level. There is no tracking code. Only the data is saved which is needed for your maximum gaming experience. The statistics you'll see inside the game will only be saved on your local machine.
