Privacy

A name, if you give one. You are asked for one when you first open the app and you can skip it. It is shown above your seat to the people you are playing with, and on the leaderboard. Use whatever you like — it is not checked against anything and nobody verifies who you are.

An anonymous account. The first time the app needs the server it creates one for you in the background. It has no email address, no password and no personal details — it is an identifier and nothing else. It exists so that a rating cannot be forged by whoever is asking.

Your games. While a table is live, the cards are on the server, because that is the only way two phones can agree about them. When a ranked game ends, the result and the rating change are kept so the leaderboard means something.

No email address, no phone number, no contacts, no location, no photographs, no advertising identifier. Nothing is read from the rest of your phone, and no identifier belonging to the device — the one Apple and Google issue for advertising included — is ever touched.

The counting described in 05 does not record what you play. Not the cards in your hand, not the name you chose, not the code of the table you are at. Nothing watches the screen and nothing records what you tap.

Nothing is sold, and nothing is shared with anybody for advertising. There is nothing to sell: a made-up name and a number.

The site is served by Vercel, the data is held by Supabase, and the counting in 05 goes to PostHog. All three keep ordinary server logs of requests made to them, and all three are processors: they hold this on our behalf and are not free to use it for their own purposes. Beyond that the only place anything is kept is your own phone, where the app remembers your name, your theme and a tally of games played so it can show you your record.

This is a family card game and children will play it. That is exactly why it asks for nothing: no sign-up, no email, no personal details, no adverts and no tracking. The counting in 05 is the same for everybody and is not personal to anyone — nothing about it identifies a player, so there is nothing there that belongs to a child any more than to anyone else. A name is optional and can be anything at all, and it is worth saying to a child that a first name or a nickname is plenty.

The app counts two things: that a round was dealt, and that a round was finished. Each carries which mode it was — on your own, round one phone, with friends or rated — how many were playing, the difficulty if you were against the house, and how long it took. That is the whole list.

It is there to answer questions the game cannot otherwise answer: whether people get to the end of a round or give up halfway, whether the hard bots are too hard, whether anybody uses pass-and-play. Solo and pass-and-play never touch the network otherwise, so without this they are simply invisible.

The counts are attached to a random identifier made up on this device the first time the app runs. It is not your phone’s identifier, it is not the advertising one, and it is not connected to your name or your account. Delete the app and it is gone for good; there is no way to link the new one to the old.

This is not tracking in the sense the App Store means it. It goes nowhere near a data broker, it is never matched against what you do in any other app or on any website, and it is not used to advertise anything to you or to anyone else.

It also honours Do Not Track and Global Privacy Control. If your browser or your phone sends either signal, nothing is counted and you do not have to touch the switch below.

Deleting the app removes everything kept on your phone. To have your anonymous account and its results deleted from the server, write to karma@jmj.fyi from anywhere and say so — there is no form and no account to log into. Tell us the name you played under, since that is the only thing that identifies you.

You can also just stop. An anonymous account with no games attached is a row with nothing in it.

For the counting in 05, the switch there is the control: turning it off stops it and discards the identifier it was attached to. We cannot go and find your past counts and delete them on request, and it would be dishonest to pretend otherwise — there is nothing recorded against them that says which ones were yours. That is the point of them being anonymous, and it cuts both ways.

If the app starts collecting something it does not collect today, this page changes at the same time, and the date below changes with it.
