Playing without an account
You can play every game without signing in. Your scores, level and achievements are then kept only in this browser on this device.
To understand how the game is used, the site records simple play events (a visit, a finished game, its score, the game played) with a random device id. It contains no name or email.
Signing in with Google
If you choose to sign in, we receive your Google name, email address and profile photo.
You also give a nickname, birth year, country and, if you like, a province. Other players see only your nickname, country, province, level, achievements and, if you allow it and you are 13 or older, your Google photo. Your birth year and email are never shown to other players.
Your game records are saved to your account so they follow you to other devices.
Where it is kept, and what we never do
Data is stored with Supabase (servers in Singapore) and the site is served by Vercel.
We do not sell your data and do not show advertising. We use it only to run the game, its rankings and to improve it.
Children
Anyone can play. To create an account, a player confirms they are 13 or older, or that a parent agrees. Accounts of players under 13 never show their Google photo.
Your choices
You can sign out at any time. To have your account and its data deleted, contact the developer at the email shown on the Google sign-in screen; it is removed within 30 days.
Clearing this browser's site data removes what is kept on the device.
