We do not collect anything about you.

What we collect

Nothing. There are no accounts to create, no sign up, no contact forms that send us your information, no advertising, and no analytics or tracking of any kind. We do not set cookies and we do not build a profile of you or your visit.

Your calculator inputs stay with you

Every number you type into a calculator is processed entirely in your own browser, on your own device. Those figures are never sent to us or to anyone else.

Two features put your inputs into a web link, but only when you choose to use them. The Share button copies a link that contains your inputs so you can reopen the same scenario or pass it to a colleague. The Print feature opens a report with those values in its address. If you share that link, send it, or scan its QR code, anyone who receives it can see the numbers it contains. Treat a share link like any other message: only send it to people you intend to.

No third parties

The site loads no third party scripts, fonts, or trackers. Fonts are served from this site itself. The only outside party involved is our host.

Hosting

The site is hosted on Cloudflare Pages. Like any web host, Cloudflare automatically processes standard request information such as IP addresses to deliver the site and protect it from abuse. That handling is governed by Cloudflare's own privacy practices. We do not receive, store, or have access to that information.

Children

This is a general audience educational resource and is not directed at children. Because we collect no information from anyone, we collect none from children.

Changes

If this policy changes, the effective date above will change with it. Because we keep no contact list, the only way we can tell you is here on this page.
