Contact

If a formula is wrong, a citation does not match its source, a link is broken or something on the site is unusable with a keyboard or a screen reader, please say so. Corrections to the equations are the most valuable thing anyone can send.

Email: hello@example.com

OWNER PLACEHOLDER: replace the contact address in src/config/site.ts before launch. It appears here, in the privacy policy, in the terms and in security.txt, and changing that one file updates all of them.

Please include the page address and, for a formula correction, the published source you are working from. That makes the fix verifiable rather than a matter of opinion.

Why there is no contact form

A form needs somewhere to send the submission, which means a server, which means somewhere your message is stored and something else to secure. This site is static files with no backend, and keeping it that way is the reason nothing you type into a calculator can leave your device. An email address is a fair trade for that.

What to expect

This is a small site run by one person. Corrections to formulas and accessibility problems are prioritised over everything else.
