Privacy in this preview

This describes the local preview as of September 7, 2026. It is not a statement about the separate, existing WordPress site.

Your worksheet

The room worksheet calculates in your browser. It does not send measurements to a server or save them in cookies or browser storage. Refreshing, leaving and returning, or using Reset all clears the worksheet. Printing uses your browser's print feature; a printout or saved PDF remains wherever you put it.

Other data

This preview has no analytics scripts, advertising embeds, account signup, or message submission. The server serving the pages may receive ordinary page requests. This page does not establish a server-log retention policy.

Outside links

Source links open third-party websites with their own privacy practices. This preview contains no affiliate purchase links and does not claim an active affiliate-program relationship.

The privacy notice must be reviewed against the actual hosting, logging, and any added services before a public launch.
