Frequently Asked Questions
Can you check my numbers?
We’re unable to review or interpret individual calculator results on a personal basis. Our tools are designed to be self-explanatory — if a result seems unexpected, try re-reading the tool’s explainer section or consulting a registered dietitian or physician.
Can I embed a HealthCal calculator on my site?
We don’t currently offer embeddable widgets. If you’re interested in a partnership or licensing arrangement, email press@healthcal.org.
I found an error in one of your formulas. What should I do?
We take accuracy seriously. Please email bugs@healthcal.org with the calculator name, the result you received, and the source you believe contradicts it. Our medical advisor reviews all such reports.
Do you accept guest posts or sponsored content?
We do not publish sponsored content, advertorials, or paid placements. All content on HealthCal.org is written or reviewed by our team.
