Contact Us
One email address, read by a person. Tell us what is wrong, what is unclear, or what you would like to see.
We read everything that arrives and reply to most messages within a few business days. There is no contact form because forms collect personal data, and we would rather not.
What to include
- For a factual correction, the page address and the exact sentence or figure.
- For a calculation problem, what you entered and what you expected to see.
- For a technical issue, your browser and device, and a screenshot if you have one.
- For a translation problem, the language and the page where it appears.
What we cannot help with
We cannot give medical advice, interpret your lab results, or tell you whether a particular weight is safe for you. That requires a clinician who knows your history. For anything urgent, contact a doctor or your local emergency number.
We also do not accept paid links, sponsored posts or guest articles. The site has no sponsored content, and we intend to keep it that way.
Privacy
If you email us, we keep your message only as long as it takes to deal with it. We do not add addresses to any list and we do not share them. See our Privacy Policy for details.
