A random token in your browser lets you resume games. The server stores a one-way hash, saved game results, dates and voluntary missing-answer reports. No name or email is required.
Clearing browser storage removes access to your identity but does not automatically delete server records. Do not include personal details in reports. This version has no advertising. We use Google Analytics to understand visits and page usage. Google Analytics is loaded only after you choose Accept cookies in our cookie dialog. It may use cookies and process page addresses, referral sources, device and browser information, and approximate location derived from network information. Rejecting optional cookies does not affect gameplay. You can change your choice using Cookie settings in the footer. Your choice is saved in browser storage for 180 days. Game progress storage remains separate from analytics. Your browser sends its time zone name so the server can unlock daily editions at 02:00 local time.
Cloudflare processes request information to host and secure the service. Sharing only opens a dialog after you choose it; nothing is posted automatically.
