Privacy policy

Last updated 26 August 2026

This is a game. The page says exactly what it keeps, why, and how to be rid of it. It is short because there is not much.

What is kept

A player id generated on your device. If you sign in: the name on your Google account and Google's identifier for it. Your games — the moves, the result, your rating. Coins, season progress and the items you own. Your friend list and friend code. Counters for the daily free games and for rewarded ads.

What is not kept

Your email address. Signing in reads it out of Google's token to check the token, and to see whether the account is the site owner's own — that is the only thing that opens the operator's page. It is compared and thrown away; it is never written down. There is no password, because there is nothing here to have one. No location, no contacts, no photos, no microphone.

Who can see it

Other players see your display name, your rating and your friend code. Nothing else, nothing is sold, and nothing goes anywhere except the services below.

The services this uses

Google Sign-In checks who you are. Google AdMob serves the rewarded ads in the Android app. This website runs no ad network: what you see here is served from this site itself, tracks nothing, and involves no third party. Cloudflare sits in front of the server. Each has its own privacy policy.

Where it is kept

On a server in Osaka, Japan (Oracle Cloud), and in your browser's own storage on this device.

Deleting it

Deleting your account clears the Google connection, the name, the friend code, the friend list, the items, the coins and the rating — immediately and for good. The record of games you played stays, with your name taken off it: the other player has a right to their own history too.

Children

This game is not aimed at children under 13, and no account is knowingly made for one.
