Privacy Policy

Information We Collect

Health Calculator is committed to protecting your health privacy. Our health and fitness calculators operate entirely client-side, meaning your health data, body measurements, and personal information remain in your browser and are never transmitted to our servers. We collect only anonymous usage data through Google Analytics to improve our services, including:

• Pages visited and health calculators used
• Time spent on site and calculator usage patterns
• Device type and browser information
• Geographic location (country/region level only)

Important: We never collect, store, or transmit any personal health information such as body measurements, weight, height, body fat percentage, or health calculations.

How We Use Your Information

The anonymous analytics data we collect is used solely for:

• Improving our health calculator functionality and user experience
• Understanding which health tools are most useful to fitness enthusiasts
• Identifying and fixing technical issues with our calculators
• Making decisions about future health calculator development
• Ensuring our tools meet the needs of athletes and health-conscious individuals

Health Data Security

Your health privacy is protected through several measures:

• All health calculations are performed locally in your browser
• No personal or health information is ever stored or transmitted
• Your body measurements, weight, and fitness data never leave your device
• We use HTTPS encryption to secure all communications
• Analytics data is anonymized and aggregated
• No registration or account creation required

Cookies and Tracking

We use Google Analytics, which employs cookies to track anonymous usage data. You can opt out of this tracking by:

• Using browser privacy settings to block cookies
• Installing the Google Analytics Opt-out Browser Add-on
• Using incognito/private browsing mode
• Enabling "Do Not Track" in your browser settings

These cookies do not collect any personal health information and are used only for understanding general usage patterns.

Third-Party Services

We use the following third-party services:

• Google Analytics for anonymous usage tracking (no health data collected)
• Tailwind CSS for styling (no data collection)
• Chart.js for health visualization (no data collection)
• React components for calculator interfaces (no data collection)

None of these services have access to your health calculations or personal information.

Data Retention

Since we don't collect personal health information, there is no personal data to retain or delete. Your health calculations exist only in your browser session and are automatically cleared when you close your browser or navigate away from the site.

Updates to Privacy Policy

We may update this privacy policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. Any changes will be posted on this page with an updated effective date. Continued use of our health calculators after such changes constitutes acceptance of the updated policy.
