Privacy and cookies

We keep the bare minimum — only what's needed so your game progress isn't lost.

What is stored

• mj_pid cookie — a random player ID. The server uses it to find your statistics and unfinished games. It contains no personal data and is created only after your first move.
• csrftoken cookie — technical protection against forged requests.
• mj_lang cookie — your chosen site language.
• Browser storage (localStorage) — the current game and theme settings, so the game restores instantly.

What is stored on the server

For each player: started games (deal number, moves, time) and summary statistics per layout. We don't collect names, email addresses or other personal data, don't share data with third parties and don't use it for advertising.
