Privacy Policy

Last updated: June 2026

The short version

HealthCalc runs entirely inside your web browser. The measurements, dates and other details you enter are never uploaded to, transmitted to, or stored on any server we operate. When you close the tab, they are gone.

Your health data

Every calculation happens privately on your own device using JavaScript. We never see what you type and keep no copies — which matters, because health details are personal.

Third-party resources

Application assets are served from a content delivery network (CDN) for speed. These requests deliver application files only — never the values you enter.

Analytics & advertising

We may use privacy-friendly analytics to understand which calculators are used, and may show ads to keep the tools free. If cookies that require consent are introduced, you will be shown a consent banner and this policy will be updated accordingly.

Not medical advice

The results are for general information and education only — not a diagnosis, treatment or a substitute for professional care. Talk to a qualified clinician about your health.
