Privacy

DUPR Lab is an unofficial, independent tool. It is not affiliated with, endorsed by, or operated by DUPR.

Signing in

When you sign in, your DUPR email and password are sent directly to DUPR to start a session, the same way the DUPR website does it. Your password is never saved or logged. DUPR returns a session token; we store it encrypted so your match history can sync. You can end this at any time with Delete my data in the account menu, or by changing your DUPR password.

What we store

• Your DUPR profile name, id and ratings, and your DUPR match history (players, scores, ratings at the time).
• Anything you add here: game notes, journal sessions, and the results of league-sheet photo imports. Photos themselves are not kept; they are sent once to an AI model (Anthropic Claude) to read names and scores.

What we don't do

• No ads, no selling or sharing your data, no posting anything to DUPR on your behalf.
• Other users can't see your notes, journal or imports.

Deleting

Delete my data removes your games, notes, journal, imports and DUPR session from our database immediately.
