+
+## Overview
+
+Normogen is a privacy-focused health data tracking and management platform. The name comes from Mapudungun, relating to "Balanced Life."
+
+## Vision
+
+To record as many variables related to health as possible, store them in a secure, private manner, to be used by **you**, not by corporations. From medication reminders to pattern analysis, Normogen puts you in control of your health data.
+
+## Technology Stack
+
+### Backend
+- **Framework**: Axum 0.7.9
+- **Runtime**: Tokio 1.41.1
+- **Middleware**: Tower, Tower-HTTP
+- **Database**: MongoDB (with zero-knowledge encryption)
+- **Language**: Rust
+- **Authentication**: JWT (PBKDF2 password hashing)
+
+### Mobile (iOS + Android) - Planned
+- **Framework**: React Native 0.73+
+- **Language**: TypeScript
+- **State Management**: Redux Toolkit 2.x
+- **Data Fetching**: RTK Query 2.x
+
+### Web - Planned

+- **Language**: TypeScript
+- **State Management**: Redux Toolkit 2.x
+
+### Deployment
+- Docker on Linux (Homelab)
+
+## Key Features
+
+- 🔐 **Zero-knowledge encryption** - Your data is encrypted before it reaches the server
+- 👥 **Multi-person profiles** - Track health data for yourself, children, elderly family members
+- 👨‍👩‍👧‍👦 **Family structure** - Manage family health records in one place
+- 🔗 **Secure sharing** - Share specific data via expiring links with embedded passwords
+- 📱 **Mobile apps** - iOS and Android with health sensor integration (planned)
+- 🌐 **Web interface** - Access from any device (planned)
+
+## Health Data Tracking
+
+- Lab results storage
+- Medication tracking (dosage, schedules, composition)
+- Health statistics (weight, height, trends)
+- Medical appointments
+- Regular checkups
+- Period tracking
+- Pregnancy tracking
+- Dental information
+- Illness records
+- Phone sensor data (steps, activity, sleep, blood pressure, temperature)
+
+## Security Model
+
+- **Client-side encryption**: Data encrypted before leaving the device
+- **Zero-knowledge**: Server stores only encrypted data
+- **Proton-style encryption**: AES-256-GCM with PBKDF2 key derivation
+- **Shareable links**: Self-contained decryption keys in URLs
+- **Privacy-first**: No data selling, subscription-based revenue
+- **JWT authentication**: Token rotation and revocation
