1 Overview
AnionGapCalculation.com ("Website," "we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you visit our Website.
Our Website provides free clinical calculators that run entirely in your web browser. We have designed our platform with a privacy-first approach, minimizing data collection to only what is necessary for the Website to function.
2 Information We Collect
We collect minimal information to improve our service:
| Data Type | Purpose | Stored Where |
|---|---|---|
| Anonymous usage analytics | Understand which tools are most used | Analytics provider |
| Browser type & device info | Optimize performance & compatibility | Analytics provider |
| Language preference | Serve content in your preferred language | Your browser (localStorage) |
| Contact form submissions | Respond to your inquiries | Our email system |
3 Information We Do NOT Collect
We want to be explicitly clear about what we never collect:
- Patient data or health information — All calculator inputs stay in your browser
- Personal identification information — No accounts, no logins required
- Lab values or calculation results — Nothing is transmitted to our servers
- IP addresses for tracking — We don't maintain IP-based user profiles
- Financial or payment information — Our service is completely free
4 How We Use Information
The limited information we collect is used solely to:
- Improve the performance and usability of our calculators
- Identify and fix bugs or technical issues
- Understand which tools are most valuable to our users
- Respond to user inquiries submitted through our contact form
- Ensure the Website functions correctly across different devices and browsers
We do not sell, trade, or rent any user information to third parties.
5 Cookies & Local Storage
Our Website uses minimal browser storage:
- localStorage: Used to save your language preference so the site displays in your chosen language on return visits. This data never leaves your browser.
- Essential cookies: May be used by our hosting provider for basic functionality (e.g., security, load balancing). These are strictly necessary and cannot be opted out of.
- Analytics cookies: If we use analytics, we configure them to anonymize data and respect Do Not Track (DNT) browser settings.
We do not use advertising cookies, social media tracking cookies, or any cookies that create persistent user profiles.
6 Third-Party Services
We may use the following types of third-party services:
- Hosting provider: To serve the Website reliably and securely
- Analytics: Privacy-focused analytics to understand aggregate usage patterns (no individual tracking)
- CDN (Content Delivery Network): To deliver assets quickly to users worldwide
We carefully select third-party providers that align with our privacy commitments. We do not use any advertising networks or data brokers.
7 Data Security
We implement appropriate technical measures to protect any information associated with our Website:
- HTTPS encryption for all data in transit
- Client-side processing — calculator data never touches our servers
- Regular security reviews of our codebase
- Minimal data collection reducing our attack surface
While no method of electronic transmission is 100% secure, our privacy-first architecture means there is minimal data at risk.
8 Children's Privacy
Our Website is designed for healthcare professionals, medical students, and educators. We do not knowingly collect personal information from children under 13 years of age. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.
9 Your Rights
Depending on your jurisdiction, you may have the following rights regarding your data:
- Right to access: Request information about what data we hold about you
- Right to deletion: Request deletion of any personal data we may have
- Right to opt out: Disable analytics tracking via your browser's Do Not Track setting
- Right to portability: Request your data in a portable format
- Right to complain: Lodge a complaint with your local data protection authority
Since we collect minimal data and do not require user accounts, most of these rights are inherently satisfied by our privacy-first design.
