Privacy Policy

We collect nothing you type. All dimensions, fill factors and results stay in your browser and are never transmitted anywhere. There is no account system, no form that stores what you enter, and no advertising network on this site.

This site sets no cookies. A single one-pixel image is requested when the page loads so we can count how many times it was opened; it records nothing about you beyond the fact that a request happened, and it cannot identify you or follow you to other sites.

There are no third-party scripts, fonts, frameworks or trackers of any kind. The page is plain HTML, CSS and JavaScript served as static files — which is also why it loads as quickly as it does and why it keeps working with a poor connection.
