On your device, and on the server under a key that only your device holds. There is nothing to sign up for. In a browser, if the game’s data is cleared, your progress comes back the next time you play. In the apps, a phone’s backup takes it to a new phone, and Game Center or Play Games finds it again on another device.
The key is the only way to it. Clearing this site’s cookies in your browser, or deleting the game with no backup, loses the key and your progress with it. Settings in the game can delete your progress, on your device and on the server.

Privacy says what it collects.
To delete everything Platform Pixels keeps about you, open Settings in the game (the gear on the home screen) and choose Delete my data. It works in the apps and in a browser, and takes effect at once.
Without the game, email support@platformpixels.com and say which device you play on, or your Game Center or Play Games name, and a person will delete it for you.
Deleting removes your player and all of its devices: best times, coins, saved runs, every attempt, and each device’s install id, system and place (country and city). None of it is kept. The mailing list is apart from the game and is not touched; to leave it, write to the address above.
