Privacy Policy
Your privacy is our priority. Learn how we protect your data and ensure your calculations remain private.
Last updated: January 11, 2026
Our Privacy Commitment
MedMath is designed with privacy at its core. We believe your health calculations should remain private and under your control.
No Data Storage
We never store your calculation inputs or results on our servers
Local Processing
All calculations happen in your browser, nothing is transmitted
No Tracking
We don't use tracking scripts or collect personal information
What Information We Collect
Calculator Input Data
What it is: The values you enter into our calculators (blood pressure readings, glucose levels, medication information, etc.)
How we handle it: All calculations are performed locally in your web browser using JavaScript. This data never leaves your device and is never transmitted to our servers or any third party.
Storage: Input values are temporarily stored in your browser's memory while you use the calculator and are cleared when you close the page or navigate away. We do not use cookies or local storage to persist this information.
Technical Information
What it is: Basic technical information that web servers typically collect, including:
- Your IP address
- Browser type and version
- Operating system
- Pages visited and time spent on site
- Referring website (if applicable)
How we use it: This information is collected automatically by our web hosting provider for security purposes, server maintenance, and to understand general usage patterns. It is not linked to any personal health information or calculator inputs.
Email Communications
What it is: If you contact us via email at reach@medmath.fyi, we collect your email address and the content of your message.
How we use it: We use this information solely to respond to your inquiry, provide support, or address reported issues. We do not add your email to marketing lists or share it with third parties.
What We Don't Do
No Third-Party Analytics
We do not use Google Analytics, Facebook Pixel, or any other third-party tracking or analytics services.
No Data Selling
We never sell, rent, or share your information with third parties for marketing or commercial purposes.
No Account Requirements
We don't require you to create accounts, log in, or provide personal information to use our calculators.
No Cookies for Tracking
We do not use cookies to track your browsing behavior or identify you across sessions.
Data Security
Since your calculator inputs never leave your device, the security of your health data depends primarily on your own device security. We recommend:
- Using up-to-date browsers with security patches
- Avoiding public or shared computers for sensitive calculations
- Clearing your browser history if using a shared device
- Using secure internet connections (avoid public Wi-Fi for sensitive data)
For the limited data we do collect (server logs and email communications), we implement industry-standard security measures including:
- HTTPS encryption for all connections to our website
- Secure hosting infrastructure with regular security updates
- Limited access to server logs and email communications
- Regular security audits and monitoring
Third-Party Services
MedMath uses minimal third-party services:
Web Hosting
Our website is hosted on secure infrastructure. The hosting provider may collect standard server logs (IP addresses, access times) for technical and security purposes. This data is not shared with us in a personally identifiable format.
Content Delivery
We may use content delivery networks (CDNs) to serve static assets (CSS, JavaScript, images) for faster load times. CDNs may log your IP address for performance and security purposes but do not track your calculator usage.
We do not integrate with social media platforms, advertising networks, or analytics services that would track your behavior.
Your Rights and Choices
Because we don't collect or store your personal health information, most privacy concerns are inherently addressed by our architecture. However, you have the following rights:
Access and Deletion
If you've contacted us via email and wish to have your email address and correspondence deleted, contact us at reach@medmath.fyi.
Browser Controls
You can clear any temporary data stored in your browser by closing the calculator tab or clearing your browser cache. Your browser settings also allow you to disable JavaScript, though this will prevent the calculators from functioning.
Do Not Track
Since we don't track your behavior, enabling "Do Not Track" in your browser settings has no additional effect, but we respect this preference.
Children's Privacy
MedMath is designed for general audiences and does not knowingly collect personal information from children under 13. Our calculators can be used by anyone, but we do not specifically target or market to children. Parents and guardians should supervise children's use of medical calculators and interpret results appropriately.
International Users
MedMath is accessible worldwide. Because calculations happen locally in your browser, your health data never crosses international borders. The limited technical data we collect (server logs) may be stored on servers located in the United States.
If you are located in the European Economic Area (EEA), United Kingdom, or other regions with data protection laws, your use of this site constitutes consent to any processing of technical information as described in this policy.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will update the "Last Updated" date at the top of this page.
Material changes to this policy will be prominently displayed on our website. We encourage you to review this Privacy Policy periodically to stay informed about how we protect your privacy.
