Common questions

My calculator result seems wrong — what should I do?

Double-check that you selected the right unit system (metric vs. imperial) and that your inputs are in the expected units. Calculator results are statistical estimates based on population averages and may differ from clinical measurements. If you believe there is a formula error, please email us with the calculator name, your inputs, the result you got, and the result you expected.

I lost my Health Planner profile — can you restore it?

Your Health Planner profile is stored only in your browser's localStorage. We never receive or store it on our servers, so we are unable to restore it. If you cleared your browser data, switched browsers, or used a different device, the profile will no longer be available. You can re-enter your profile in under 60 seconds on the Health Planner page.

Can I use your calculator content on my own site?
