Privacy Policy

Last updated on 26 October 2026.

What we keep

• Your name. You pick it yourself and it may be a nickname.
• Your games. The result, and the list of moves so the server can check that the result holds up.
• Your puzzles. Which ones you solved and in how many tries.
• One token per device. That is how the server knows it is you.
• Reports and blocks. If you report someone, we record who you reported, why, at which table and what you wrote alongside it. That last part is a free text field and it is about another person, so keep it to what happened. Who you block is recorded too: that is what keeps people apart at the table.
• Your friends. Who your friends are, who you asked, and when your app was last open. That is how your friends see whether you are online. If you ask someone by email address, we keep that address with the request and send one email to it.
• Your photo. Only if you choose one yourself. The app turns it into a square of 512 pixels on your device, and the server removes the data inside it, such as where it was taken. Before others see it, a computer checks it, and an admin if needed. That computer is Claude, made by Anthropic. Anthropic gets to see the photo for this and processes it on our behalf. The verdict is about the photo and builds no profile of you.

What we do not keep

• No email address, unless you enter one yourself: your own to log in, or that of someone you ask to be friends.
• No password.
• No location, no address book, no advertising data.
• Nobody looking over your shoulder from outside: there is no analytics and no tracker in it.

For how long

• The list of moves of a game goes after a year. The result stays, because that is your history.
• A token that has not been used for a year expires.
• An account that did nothing and played nothing for two years is cleared out.
• A report goes half a year after it has been dealt with, together with what was written. A block stays until you remove it yourself, under Profile.
• A request by email address that nobody answers goes after thirty days, together with the address. An invitation to a table goes after a day. A friendship stays until one of you ends it.
• A photo that was rejected, replaced or removed goes after seven days. Your current photo stays until you remove it yourself or delete your account.

Where it is kept

On one server in the Netherlands, at Sinoxi. Nothing goes to other parties, with one exception: a photo you choose yourself passes Anthropic to be checked. Beyond that, no cloud service reads along. The connection with the app runs over https and wss.

Deleting

In the app under Profile there is one button that deletes your account and everything attached to it. No cooling-off period, no "we will hold on to it for a while": gone is gone. If that does not work, email info@troefmasters.nl and it is done by hand.

Videos on TikTok

Troefmasters posts short videos about the app to its own TikTok accounts. The admins do this with the TikTok Content Posting API. For those accounts we only keep what TikTok returns when one is connected: the name, an id and the tokens that allow posting. The tokens are stored encrypted on our server and are only used to upload a video and to check that it was published.

Nothing about players is sent to TikTok. The app never asks you to log in with TikTok and posts nothing on your behalf.

A connected account can revoke access at any time in the TikTok settings, or by emailing us. We then delete the tokens.

Who can see it

The server admin. Nobody else. In a tournament other players see your name and your results, which is the point of a tournament.

Your friends see your name, whether you are online and which open table you are at. You can turn that last part off under Preferences. They do not see the code of a private table.

Others only see your photo once it is approved. Until then only you see it, along with the computer and the admins who check it. Anyone you blocked does not get to see it.

A report is read by the admins and by nobody else, not even the person it is about. So whoever you reported does not hear from us what you wrote. They only notice that a ruling was made if it affects them.
