Privacy policy
Players never sign up or give a phone number: they join with the session code and a name shown only in that session. Their answers and points are kept with the session, which is deleted with everything in it 365 days after it ends.
A coordinator signs up with a name, a phone number and a password stored as a one-way hash; e-mail is optional, for contact. The phone is verified with a code through the Messaging Gateway; the game never stores the code.
We keep the answers coordinators approve or reject, with no name, session or number, to improve correction.
When verdict suggestions are on, only the answer words, the letter and the field name, with no name or number, go to Anthropic's Claude service to suggest a verdict to the coordinator, who decides.
Payments go through the central payment gateway; card details never reach the game. We keep the order, its amount and status only.
We do not store IP addresses. To limit repeated attempts we keep a one-way fingerprint of it, from which the address cannot be recovered.
Cookies
All are the game’s own: no third parties, no advertising, no cross-site tracking. The necessary ones run the game, sign-in and language; the source cookie feeds reports only.
Night or day mode and sound are kept on your device only and never sent.
You can delete these cookies in your browser settings at any time; a player then rejoins with the code and a name.
