Our Core Principle: No Health Data Collection
MedicalCalculatorHub does NOT collect, store, or transmit any patient health data or Personal Health Information (PHI) entered into our calculators.
All calculator computations happen entirely in your web browser on your device. No data is sent to our servers. This means:
- Patient names, ages, and clinical values remain completely private
- Calculation results are not stored or logged
- Your browsing history of calculator use is not tracked
- No health records are created or maintained
Your clinical information is never at risk from MedicalCalculatorHub.
What Information We Collect
1. Web Server Logs (Automatic)
Like all websites, we automatically collect standard server logs when you visit, which may include:
- Your IP address (anonymized after 30 days)
- Browser type and version
- Operating system
- Pages visited and time spent
- Referrer page (how you found us)
- Date and time of visit
Retention: Server logs are retained for 30 days, then permanently deleted.

- Traffic sources (how you found us)
What is NOT tracked: We have disabled User-ID tracking, interest-based advertising, and demographic data collection in Google Analytics.
