Privacy

This site does not require an account and does not ask for payment details. We do not sell your data.

Your plans are saved in your own browser (local storage). They are never uploaded to our servers. A share link carries the plan inside the link itself. The site also remembers your language, units, light or dark theme and whether you have seen the tutorial, in the same local storage.

To work offline, the site installs a service worker that keeps a copy of its own pages and scripts in your browser cache. It never caches your plans on a server.

If advertising (such as Google AdSense) is enabled in the future, this page will be updated to describe the cookies and data involved, and to explain how to manage your consent.
