1. Introduction
Welcome to MedCalc. Your privacy and the security of your data—and your patients’ data—are our highest priorities. This Privacy Policy outlines how we collect, use, and protect information when you visit our website or use the MedCalc mobile application (the “App”).
By using MedCalc, you agree to the collection and use of information in accordance with this policy.
2. Zero-Knowledge & PHI (Protected Health Information)
We do not collect, store, transmit, or mine Protected Health Information (PHI).
MedCalc is designed as a clinical decision-support tool. All patient-specific medical calculations and data inputs are processed locally on your device. We employ a zero-knowledge architecture regarding patient data.
- We cannot see the clinical data you enter.
- We do not back up patient data to our servers.
- Once you clear a calculation or close the app, the inputted clinical data is wiped from the device’s active memory.
3. Information We Do Collect
While we do not collect patient data, we do collect limited information regarding your account and app usage to provide and improve our service:
- Account Information: If you register for a premium MedCalc account, we collect your name, email address, and professional credential (e.g., MD, DO, RN) to verify your account and provide support.
- Usage Data: We collect anonymized, aggregated data on how the App is accessed and used. This includes information such as your device type, operating system, which calculators are most frequently used, and app crash logs. This data is strictly used to debug the app and improve user experience.
- Payment Information: For paid subscriptions, payment processing is handled securely by our third-party payment processors (e.g., Apple App Store, Google Play, or Stripe). We do not store your credit card details on our servers.
4. How We Use Your Information
The limited information we collect is used solely for the following purposes:
- To provide, maintain, and secure the MedCalc App.
- To notify you about critical updates, new medical formulas, or changes to our service.
- To provide customer support and respond to your inquiries.
- To monitor the usage of the App to detect, prevent, and address technical issues.
5. Data Security & HIPAA Compliance
We adhere strictly to security protocols designed to meet or exceed the Health Insurance Portability and Accountability Act (HIPAA) standards:
- Encryption: Any non-PHI data transmitted between your device and our servers (such as account login credentials) is secured using end-to-end 256-bit AES encryption.
- Infrastructure: Our servers are hosted on HIPAA-compliant, enterprise-grade cloud infrastructure with strictly controlled access.
- No Third-Party Selling: We will never sell, rent, or trade your personal information to third-party advertisers or data brokers.
6. Third-Party Services
We may employ third-party companies to facilitate our service (such as analytics providers or cloud hosting). These third parties have access to your strictly non-PHI Personal Data only to perform these tasks on our behalf and are bound by Business Associate Agreements (BAAs) where applicable, obligating them not to disclose or use it for any other purpose.
7. Your Data Rights
Depending on your location, you may have the following rights regarding your personal data:
- The right to access, update, or delete the personal information we have on you.
- The right of rectification if that information is inaccurate or incomplete.
- The right to withdraw consent at any time where MedCalc relied on your consent to process your personal information.
To execute any of these rights, please contact us via the information provided below.
8. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last Updated” date at the top. We advise you to review this Privacy Policy periodically for any changes.
