PYRAVOID has no adverts, no analytics and no tracking, and never asks for your name, email or any account.
Progress, medals, scores, ghost runs, levels you build and settings are saved in the game's local storage on your device.
To take part in the leaderboards, the game creates an anonymous account for your device (a random ID from Google Firebase; no personal details). When you clear a stage it uploads your best time, score and run score, the movement path of your fastest run (so others can race your ghost), the nickname you choose (or a random one like PYRA-1234) and the time of the upload. This information is visible to other players on the leaderboards. It is stored with Google Firebase.
Nicknames are filtered; please don't use your real name. To have your leaderboard entries removed, contact the developer through the store listing and include your nickname.
The game downloads its code, fonts and music from the web the first time it runs. These are ordinary file downloads.
