Privacy policy

Effective date: 2026-07-16

This site does not require user accounts. Calculator inputs (dates, measurements, sex) are processed in your browser for the purpose of showing results. We do not operate a database of child health information and do not intentionally collect or store those inputs on our servers.

Hosting providers may process standard technical logs (for example IP address, user agent, and requested URLs) as part of delivering the static website. We do not currently load third-party analytics scripts in v1.

Future display advertising, if enabled, may involve third-party ad technology. This policy will be updated before such scripts are added.
