What is collected
Nothing is collected by this site. There are no analytics scripts, no advertising pixels, no session recording and no third-party embeds. Every illustration is generated for this site and served from the same origin.
Local storage
Some tools store your inputs in your own browser so a calculation survives a page refresh. This data never leaves your device and can be cleared at any time from your browser settings. The 3D simulations run entirely in the browser and upload nothing.
Cookies
This site does not set cookies.
Third parties
No third-party scripts are loaded. Fonts and 3D libraries are bundled locally with the site rather than fetched from a content delivery network, which means visiting a page makes no request to any other domain.

Questions about this policy can be sent to the address on the contact page. If this policy changes, the review date at the top of this page changes with it.
Summary. No analytics, no cookies, no third-party scripts, no accounts. Anything you type into a calculator or simulator stays in your browser.
