Calculator data

Calculations run in your browser. This site does not require an account and does not intentionally collect names, medical histories, diagnoses, or treatment records.

Share links

If you choose “Copy share link,” the numeric calculator inputs are placed in the page URL. Anyone who receives that URL can see those values. URLs may also appear in browser history, server request logs, or tools used by the recipient. Do not place personal or sensitive information in a shared URL.

Analytics and infrastructure

The site uses Google Analytics 4 and may use Cloudflare Web Analytics and Cloudflare infrastructure to understand visits, usage patterns, performance, and security events. Google Analytics may process device, browser, approximate location, referral, and interaction data and may use cookies or similar technologies. We do not use advertising pixels or sell personal information. You can learn more in Google’s privacy policy.

Local browser features

Copy buttons use your browser clipboard when you activate them. The calculator does not use local storage or create a user profile.

External links

Reference links may lead to third-party websites with their own privacy practices. Review those policies before providing information to another site.

Changes

Material changes will be reflected on this page with a revised effective date.
