An open plan for your data.
Three boundaries matter: the puzzle in memory, choices on this device and email you deliberately send.
Puzzle calculations
Selected corners, numbered clues, placed rooms and the undo list are processed by the browser. None of those items is submitted to an account or game endpoint. They disappear when the page is reloaded. Choosing another plan also starts that activity again.
Preference records
A local record stores your decision about optional preferences for no more than 120 days. A second record may hold a reduced-motion setting when permission has been given. The Cookies page names both keys and provides a way to remove them without affecting other websites.
The contact workspace
The enquiry form accepts an email address, an optional name, a subject, optional plan coordinates and a message. Creating its draft only assembles those entries into visible text. There is no background form submission or server-side ticket creation in this website.
A message you send
Following the mail link hands the prepared text to your mail application. Sending it is a separate action in that application. The recipient’s email service then receives the information included in your message. Supply only the board details and contact information needed to explain the enquiry.
Requests to the host
Serving the published pages may generate technical records at the hosting provider, such as requested resources, request times or IP addresses. Those records are separate from the chamber board. The site does not load analytics code, marketing cookies, remote fonts or advertising pixels.
Questions and corrections
Address a privacy question to [email protected]. Explain whether it concerns local preferences or a previously sent message; they are handled in different places. This notice should be reviewed if a future version adds accounts, remote saving or another data-processing feature.
