Privacy

Last updated 6 October 2026

You can play without an account. We don't know who you are, and we don't want to.

An anonymous player id in a cookie (dd_pid, one year), so your results, streak and rival record follow you between visits on this browser.
Your plays: the bid, debt and move you chose, your score, when you played, and anything you type in “What did you miss?”.
Anonymous usage events: which screens you reached, whether you opened “Why?” or tapped Share, and similar. We use them to see where the game is confusing and whether it spreads.
Where your first visit came from, at the level of “LinkedIn”, “X”, “a shared result” or “direct”; whether you were on a phone or a computer; and which country you were in, as our host works it out from the connection.
A deal in progress is saved only in your own browser, so a reload doesn't lose it. It isn't sent to us until you submit.

Your name or email (there are no accounts yet).
Your IP address. To stop abuse we count requests against a scrambled, one-way version of it, which can't be turned back into the address and is cleared within a day.
The page you came from, beyond the coarse source above.
Advertising or third-party trackers. We don't sell or share data.

The game runs on Vercel and its database on Supabase, in Mumbai.
Usage events are kept for 90 days, then reduced to daily totals with no player ids.
Plays are kept while the game runs, so your history and the shared result links keep working. Backups are kept for 30 days.
A shared result link is public: anyone with it can see your grades and score, but not who you are.

We'll update this page if what we collect changes. See also the terms.
