Privacy

The actual behaviour of the site: no accounts, server forms, analytics, ads or cookies. All computation happens in your browser.

What the site does with your data

It sends nothing. The dimensions you enter and the choices you make in the tools are processed locally and live in the memory of the tab; reloading the page resets the state.

Analytics and monitoring

Disabled. The site contains no counters, pixels or third-party scripts. If the owner later enables analytics, this page will say so.

Cookies and storage

No cookies are used. The quick orientation on the home page passes parameters to the assistant through sessionStorage of the same tab; the storage clears when the tab closes.

Network and content

All resources are local: styles, scripts, fonts and graphics are served by the site itself. The CSP policy blocks third-party connections.
