What to include

To help you quickly, please tell us which page or tool you were using, your browser or device if the issue is technical, and what you expected to happen. For content corrections, include the topic and, if possible, the source you believe we should consider.

Common requests

• Feedback or corrections — something inaccurate or unclear on the site? Tell us and we will review it against the cited research.
• Privacy requests — see our Privacy Policy for how data is handled and Terms of Service for site usage terms.
• Technical problems — the tracker stores data only in your own browser, so we cannot recover lost entries, but we can help troubleshoot.

A note about privacy

Calculator inputs and tracker logs never leave your browser, so please do not send detailed health information by email unless it is necessary for your request — email is handled like any regular email correspondence.
