# Normogen

## 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.

## Key Features

### Core Functionality
- 🔐 **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
- 🌐 **Web interface** - Access from any device

### 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)

## Architecture

### Technology Stack
- **Backend API**: Rust
- **Web Server**: Node.js
- **Database**: MongoDB (with zero-knowledge encryption)
- **Frontend**: Web + iOS + Android
- **Deployment**: Docker on Linux

### 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
