Privacy
The current site has no accounts, analytics, ad network, cookies, submitted forms or persistent browser storage.
No data collection
Your worksheet entries
Numbers entered into the measuring worksheet are processed in the current browser page. They are not sent to this site, saved to localStorage or placed in a database. Reloading or closing the page removes the entered state.
Printing is handled by the browser's own print dialog. The site does not receive the printed record, printer selection or job reference a user writes on paper.
Network and storage
The pages use local HTML, CSS, JavaScript and SVG files. There are no third-party runtime scripts, font requests, images, iframes or API calls. Source citations and the task-specific tool-hire links open external websites only when selected.
If this posture changes, this page and the implementation must be updated before the new collection is enabled.
