🔒 Technical Guarantee: 100% Client-Side Processing
PaedsCalc executes entirely in the local browser runtime. All entered weights, ages, selected medications, and calculated volumes are computed on your device and are never transmitted to any external web server, cloud database, or third-party analytics provider.
1. Personal & Patient Health Information (PHI)
PaedsCalc does not require, collect, transmit, or store identifiable Patient Health Information (PHI). When clinicians input patient weight or age into the calculator, that data exists purely within the browser's active volatile memory (RAM) and is discarded upon closing or resetting the session.
2. Local Storage (`localStorage`) Usage
PaedsCalc utilizes your browser's local storage solely for user experience preferences:
- Theme Preference: Remembering whether you prefer Medical Daylight or Night Shift mode.
- Favorite Prescriptions: Storing bookmarked medications for quick point-of-care 1-tap access.
- Session State: Preserving your selected clinical view while moving between tools offline.
This data never leaves your browser and can be completely cleared at any time by clearing your browser cache and site cookies.
3. Service Worker & Offline Caching
PaedsCalc registers a standard Progressive Web App (PWA) Service Worker (sw.js). The service worker caches static assets (HTML, CSS, JavaScript, icons, and medical reference formulary files) directly onto your device so the application remains fully functional during rural clinic postings, hospital elevators, or internet outages.
4. Third-Party Analytics and Advertising
PaedsCalc contains zero third-party tracking pixels, advertising networks, or data-broker trackers (e.g. No Facebook Pixel, Google AdSense, or behavioral analytics). Typography fonts (Plus Jakarta Sans) are fetched securely via Google Fonts CDN during online sessions and cached locally by the browser.
