Privacy

What we store

• The display name you type.
• A random ID that your browser creates and keeps in local storage. It links your games and stats to this device.
• The moves in each game, so the server can run the game and show its Stats afterwards. They are kept with the game.
• Your IP address, for a short time, to stop abuse such as room spam.

How long

Live games end and are removed within hours. Finished games, with every move, and your stats are kept for good, so you can look back on every game you play.

Services we use

• Railway and Vercel host the game. Finished games are kept in a Postgres database at Railway.
• Sentry receives error reports, so we can fix crashes. Reports do not include your name.
• PostHog counts page views, game events and the buttons you use, such as Play vs bots, Start and Leave. They go under the same random ID that links your stats, so a return visit counts as the same player. PostHog gets no names, sets no cookies and records no sessions.
• Both are reached through this site's own address, so they work where a browser blocks their sites.
• PostHog finds your country and city from your IP address, and keeps the address with each event.
• When a game starts, the server sends the starting player's IP address to GeoJS to find their city and country. The address is not kept.
• Resend then emails the site's owner the room code, the players' names, and that city and country. PostHog gets the city and country, not the address.

We do not sell data, show ads or track you across other sites.

Your choices

Clear this site's data in your browser to remove your device ID. Your old games and stats then stop being linked to you, and PostHog counts you as a new player.
