Privacy
Privacy.
The short version: this site does not collect anything about you, which is why there is no cookie banner to dismiss.
What Is Collected
Nothing that identifies you. There is no account system, no sign-in, no advertising network, no analytics script, no session recording, and no third-party tag of any kind. No cookie is set by this site.
Your Calculations
The numbers you type never leave your device. Every calculator runs entirely in your browser — there is no server that receives your inputs, because there is no server-side processing at all. The pages are static files.
Your inputs do appear in the address bar, which is what makes a calculation shareable as a link. That URL stays in your browser unless you deliberately copy and send it. If you share a link, whoever opens it will see the numbers it contains — worth remembering if you ever put something sensitive into a field.
Local Storage
One value is stored on your device: whether you chose the light or dark theme. It is kept in your browser's local storage, is read only by this site, and is never transmitted anywhere. Clearing your browser data removes it, and the site then follows your operating system's appearance setting.
Third Parties
There are none. Fonts are served from this domain rather than a font provider, and there is no content delivery network, embedded video, comment system or social widget. Loading a page on this site makes no request to any other company.
Pages do link to external references — code documents and standards bodies — but those are ordinary links. Nothing is requested from them until you choose to click.
Server Logs
The site is served by a static hosting provider, which — like every web host — records basic request information such as IP address, timestamp and requested URL, for security and operations. That is standard infrastructure logging, it is not used to build any profile of you, and this site adds nothing to it.
The Embeddable Calculator
If you place the embeddable version on your own page, it behaves the same way: it loads only from this domain, sets no cookies, collects nothing, and does not communicate with the page hosting it.
Children
The site is suitable for use by students of any age. Since nothing is collected from anyone, no information is collected from children either.
Changes
If this ever changes — for instance if advertising is introduced — this page will be updated before the change goes live, and anything that requires your consent will ask for it properly rather than assuming it. Last updated .
