The way to reach kcalcraft is email: support@kcalcraft.com. Every message lands in the same inbox — there is no contact form, no ticket system, and no account to log into. The site is a small independent project, and the mailbox above is the whole support surface.

What to send, depending on the issue: Calculator problems — the page URL, the values you entered, and what you expected versus what you saw. Equation or source corrections — the page, the number you believe is wrong, and the reference it contradicts (paper, PMID, or DOI preferred). Every equation on this site names its source precisely so that corrections can be checked against the primary literature; verified corrections are fixed promptly and noted in the update log on the methodology page. Business inquiries — advertising, partnerships, or press — the same address.

Replies usually arrive within two business days.
