Privacy Policy

Last updated 31 August 2026

There are no adverts and no analytics in this app. Playing on your own sends nothing anywhere. Playing online with friends handles a display name you choose and the state of the game you are playing, and nothing else.

Playing on your own

Single player runs entirely on your phone, against opponents the app plays itself. Nothing is sent anywhere, and the app works with no signal at all. There is no account, no sign-in, no email address, and no form to fill in.

Playing online with friends

Online play is a private room. Somebody hosts, the app gives them a six-character PIN, and they share it with the people they want to play with. There is no public matchmaking and no way to find a room you were not given the PIN for.

When — and only when — you host or join a room, three things are handled by our server:

• The display name you type in. Three to ten letters, digits and spaces. It does not have to be your real name, and we would rather it wasn't. Everybody else in that room sees it.
• An anonymous player ID. A random identifier the app creates for your phone so that the game can tell four players apart. It is not linked to an email address, a phone number, an Apple or Google account, or your identity in any way, because none of those are ever asked for.
• The state of the game. Who is sitting where, the cards that have been dealt and played, and the score.

Your own cards are readable only by your phone. The server is configured so that no other player in the room can read them, and that is enforced by the server rather than left to the app to respect.

Who runs the server, and for how long

Online rooms use Google's Firebase Realtime Database and its anonymous sign-in. That means the three things above are processed on Google's servers while you are playing. Google's own privacy terms for that service are at firebase.google.com/support/privacy.

A room and everything in it is deleted when the host closes it. If a host's phone loses connection abruptly, an abandoned room may sit on the server until we remove it. We are adding automatic clean-up; until then, an abandoned room holds nothing but the display names and the position of a game nobody is playing.

Nothing about a finished game is kept. There are no player profiles, no match history, no leaderboards, and no record that connects one game to the next.

Advertising and analytics

There are no adverts in this app. There is no analytics software, no tracking, no advertising identifier, and no crash reporting. Nobody is measuring what you do here. We do not sell or share anything with anybody, because there is nothing to sell and nobody to share it with.

What stays on your phone

The app keeps your settings — the difficulty you last chose, and the display name you last used, so it does not have to ask again — on your own device. That information is not readable by us and is deleted when you uninstall the app.

Children

This app is a card game intended for a general audience. Playing on your own collects nothing from anybody. Playing online handles only a display name the player chooses, which does not have to identify them and should not.

Your choices

Do not host or join a room, and nothing about you is sent anywhere at all — the whole game is still playable. If you want a room and everything in it deleted, ask the host to close it, or write to us at the address below and tell us the PIN.
