Cards Cafe has no accounts and no sign-up. We never ask for your name, e-mail, phone number or payment details, and we sell nothing to anyone. This page says exactly what is collected, why, and how to remove it.
This policy covers the website cardscafe.net and the Cards Cafe mobile app, which shows the same site. Cards Cafe is run by an independent solo developer.
The English version of this page is the authoritative one; the other languages are provided for convenience.
No name, e-mail address, phone number, postal address, payment details, precise location, contacts, photos or messages. There is no account to create, and no user database on our servers.
Your progress is stored by your browser on your own device: experience and level, wins, games and moves played, win and play streaks, your café nickname, your chosen card skin and card back, theme, language, the hint setting, first-run and banner flags, your record against each bot, your last match, and the daily-visit marker. Only the few values listed under “The leaderboard” below ever leave your device.
Clearing your browser data for this site deletes all of it permanently. We cannot restore it, because apart from the leaderboard entry described below we never had a copy.
We count how the game is used with Umami, an analytics tool we host ourselves on our own server. It sets no cookies, does not follow you to other sites, and the data never leaves our server or reaches a third party.
The events record things like a page being opened, a game started or finished against which bot, a win or a loss, the interface language, and which kind of link the visit arrived from. They are not tied to any identifier that would single you out.
Once per visit the app reports your screen size, pixel density, whether it is running as an installed app, the safe-area insets, and — only if your browser agrees to share them — the phone model and OS version.
This exists to find layout bugs on real devices. The action button was once hidden behind the system navigation bar on certain phones, and there is no other way for us to see that.
We show no adverts inside the game. Some visits, however, arrive from a Google Ads campaign, and to measure whether an advert worked the site can load Google's tag, which may set advertising cookies and share that visit with Google for conversion measurement and remarketing.
This is off by default: Google Consent Mode is set to denied before the tag loads, and in the European Economic Area and the United Kingdom we ask first. If you decline, no advertising cookies are set.
When you play a friend by link, your moves and the café nickname you chose pass through our game server so both devices stay in sync. Rooms live only in memory while the game runs and are gone when it ends — the moves, names and results are never written to disk. So that an invite link still works on another day, the server keeps one thing per friend table: a random table key and the table rules chosen (variant, deck, house rules), with the dates it was opened and last used. Nothing in it says who sat there; it is deleted after 60 days without use.
Your opponent sees your nickname and the emoji reactions you send, and nothing else about you.
When you finish a game that is not played on a single shared device, the app sends your café nickname, your avatar, your experience total and your win count to our own server, so that the leaderboard can rank them. Those few values are written to a file there rather than held only in memory, so the board survives a restart.
Stored beside them are a pseudonymous id your own device generated, a coarse device label, the day you first played, and how many separate days you have come back. For the last 120 days it also notes on which days the app was opened on that device, and on which of them you played: the date only, never the time or what you did. The note of a day you played also carries your café nickname and avatar, so a game of solitaire puts the same nickname there as a finished game would. There is no account behind that id — it identifies a browser, not a person — and none of it is shared with anyone else.
If you write to us with the Feedback button, your message is kept on the same server together with the time, the place in the app you sent it from, and that same coarse device label.
To have your leaderboard entry or a message deleted, write to cardscafe2026@gmail.com and say which café nickname you played under.
Like any website, our server receives your device's IP address with every request. The web server writes it to an access log together with the time, the page requested and your browser's self-description (user agent); the log is deleted after about two weeks and is used only to find faults and stop abuse.
Umami uses the address to work out the country and city of a visit and stores only those, never the address. The game server keeps a count of connections per address in memory for at most ten minutes, to stop floods and the guessing of table numbers, and never writes it to disk.
Cards Cafe is not directed at children under 13, and we do not knowingly collect anything from them.
You can decline advertising cookies when asked, and change your mind later from the settings menu. You can delete everything the site has stored by clearing site data for cardscafe.net in your browser, or by uninstalling the app.
If you would like us to delete something, or you have a question about this policy, use the Feedback button in the footer or write to cardscafe2026@gmail.com. There is no account to close — deleting your local data is the deletion.
If this policy changes, the date at the top of the page changes with it, and the change is listed here. Continued use after that date means the updated policy applies.
17 October 2026: added “IP addresses and server logs”. The access log and Umami's country and city were there before and are now described; only the game server's ten-minute connection count is new.
15 October 2026: “The leaderboard” now describes the 120-day note of the days the app was opened and played in, with the nickname it carries.
8 October 2026: “Playing online with a friend” now describes the table key that keeps an invite link working.
20 September 2026: “What stays on your device” and “The leaderboard” now say which values are sent to our server and kept there.
1 August 2026: first published.
