Privacy Policy
Last updated: June 2026
Information We Collect
HealthCalc is designed with your privacy as the top priority. Here's what we collect and what we don't:
Calculator Inputs
When you use our calculators, all mathematical operations happen locally in your browser using JavaScript. We do not collect, store, transmit, or log any numbers you enter into our calculators. Your weight, height, age, and other health details never leave your device.
Automatically Collected Information
Like most websites, we automatically collect standard server log information:
- Browser type and version
- Operating system
- Referring website
- Pages visited and time spent on each page
- General geographic location (country/region level)
This data is used in aggregate only, to understand site usage and improve user experience.
Cookies
We use minimal cookies for:
- Remembering your cookie consent preference
- Understanding aggregate site usage (via Google Analytics)
- Displaying relevant advertisements (via Google AdSense)
You can clear cookies anytime through your browser settings. Disabling cookies may affect some features of the site.
How We Use Information
We use collected information to:
- Improve our website and user experience
- Understand which calculators are most useful
- Display relevant, non-intrusive advertisements
- Identify and fix technical issues
- Comply with legal obligations
Third-Party Services
Google Analytics
We use Google Analytics to understand aggregate site traffic patterns. This service collects data according to Google's privacy policy. You can opt out using browser extensions like Ghostery or by enabling Do Not Track in your browser.
Google AdSense
We display advertisements served by Google AdSense. Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings.
Data Security
We take reasonable security measures to protect your information:
- HTTPS encryption for all data transmission
- Secure hosting infrastructure
- Minimal data collection principle — we collect only what we need
No method of internet transmission is 100% secure, and we cannot guarantee absolute security. However, since we don't store any personal health data, there is nothing sensitive to be compromised.
Children's Privacy
Our website is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we discover that data has been collected from a child under 13, we will delete it promptly.
Your Rights
Depending on your jurisdiction, you may have the right to:
- Access your personal data
- Correct inaccurate personal data
- Request deletion of your personal data
- Object to certain processing activities
- Data portability
Since we collect minimal personal data and no calculator inputs, most of these rights are naturally satisfied by our privacy-by-design approach.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
