Privacy policy

When you sign in with Google, we keep: your Google sign-in identifier, your email address, the unique username you choose, your ELO rating, and your game history.

We never collect a password (sign-in goes entirely through Google), nor any webcam, image, or biometric data.

Only to run the game: identify you across games, show your username to other players, calculate and display your ELO rating, and keep your game history.

With Google, only for sign-in (authentication). Feedback messages and reports are also sent to our private Discord server, only so the team can read them. With no one else. No data is sold or shared with third parties for commercial purposes.

If you send us a message (bug, suggestion) or report a player, we keep your username (or “Guest”), your message and, for a report, the reported player's username and, if you report during a game, a copy of that game's chat. These messages are only used to improve the game and for moderation, and are deleted after 12 months.

Your data is kept as long as your account exists. It is deleted immediately and permanently if you delete your account.

You can delete your account and all your data at any time, from your profile ("My account" menu → "Delete my account").

For a right of access, rectification, or any other question about your data, write to the contact address below.

This site only uses the cookies required for sign-in (session). No advertising tracking cookies.

If you accept daily game notifications, we store the delivery address provided by your browser, its encryption keys and the site language, only to notify you (your move, reminder, challenge accepted, game over). Encrypted messages go through your browser's notification service (Google, Apple or Mozilla). You can turn them off at any time in Settings or in your browser settings; this data is deleted with your account, or as soon as your device is no longer reachable.
