Privacy
Perfect Drop measures how the game is played, never who plays it. There are no accounts in the game.
The game sends anonymous gameplay events to its own server: a level started or ended, the result, the stars, how long it took and simple counters, the screen size and the game version, with a random player id made on your device and a random session id. The server does not store your IP address. Your progress (opened levels, stars) and your settings are saved on your device only.
