Privacy
A short policy, because the site genuinely collects very little. No analytics, no advertising, no third-party scripts that follow you between sites.
What is stored
Your browser stores two preferences locally: whether the sidebar is expanded, and which of the two colour themes you chose. Both live in localStorage on your device and are never transmitted.
The 3D tools store one session-only flag if you choose to load the interactive version on a small screen. It clears when you close the tab.
What is not collected
No analytics, no advertising pixels, no session recording, and no cookies set by third parties. There is no login, no profile and no server-side logging of individual visitors by us.
The contact form validates in your browser and does not submit anywhere. Nothing you type into it leaves your device.
Images and fonts
Every illustration on this site is generated by the site itself and served inline — there are no third-party image hosts. Typefaces fall back to fonts already installed on your system; none are fetched from an external font service.
The 3D library is served from this site, not from a content delivery network, so opening a simulation does not contact anyone else.
