The site
Privacy
The shortest page on this site, because there is honestly little to say.
What this site collects
Nothing. Specifically:
- No cookies are set, first-party or third-party.
- No analytics or tracking of any kind runs on any page.
- There are no forms that send anything anywhere — no contact form, no sign-up, no newsletter.
- No personal data is collected, stored or shared by this site.
The calculators
Everything you type into a calculator — heights, diameters, areas, dimensions — is processed entirely in your browser by JavaScript served from this site. Those inputs are never transmitted to this site or to anyone else, and nothing about your calculations is recorded. Close the page and they are gone.
Hosting
The site is served as static files by Cloudflare Pages. Like effectively all web hosting, the platform may process standard request logs — the technical records involved in serving a page, such as the address a request came from — as part of operating and securing its network. That processing belongs to the hosting platform, not to this site; this site adds no logging of its own on top.
If this changes
If any of the above ever changes — a cookie, a script, a form, anything — this page will change in the same release, not after it.
