The way to reach ExpectCalc is email: support@expectcalc.com. This is a one-person operation, so a single mailbox keeps nothing from falling through — every message lands in the same triage queue.
What to send where
Calculator or feature problems: the page URL, the values you entered, and what you expected versus what you saw. Screenshots help but are not required.
Data or sourcing errors: the page, the claim or number you believe is wrong, and the primary source (ACOG, IOM, or the original study) that contradicts it. Valid corrections are fixed and acknowledged.
Business inquiries: partnerships, licensing, or press — the same address. Commercial spam is filtered like anywhere else.
Personal medical questions: these cannot be answered here. ExpectCalc does not provide medical advice and does not interpret individual results; please direct those questions to your physician or midwife. Such messages receive a standard reply pointing to your care team.
Response time
Replies usually arrive within two business days. Because the site has no accounts and stores no user data, there is no self-service portal — the mailbox above is the whole support surface, and it is monitored.
