+# Normogen Project Introduction
+
+## Naming & Origin
+
+**Normogen** comes from Mapudungun (the language of the Mapuche people), relating to "Balanced Life." The commercial name is yet to be defined.
+
+---
+
+## Purpose & Vision
+
+### Vision Statement
+> "To empower individuals with complete control over their health data through secure, private, and open-source technology."
+
+### Mission Statement
+> "Build the most comprehensive, secure, and user-friendly health data platform that puts users in control, not corporations."
+
+### Core Purpose
+To record as many variables related to health as possible, store them in a secure, private manner, to be used by **the user**, not by corporations. From reminding about medication, to comparing data changes over time, and finding emerging patterns.
+
+---
+
+## What Makes Normogen Different
+
+### 🔒 Privacy-First
+- **Zero-knowledge encryption**: Your data is encrypted and only you hold the keys
+- **No data selling**: We will never sell your data to third parties
+- **Open-source**: Full transparency in how we handle your data
+
+### 👤 User-Centric
+- **You own your data**: Complete control over your health information
+- **Easy sharing**: Share specific data with healthcare providers, family, or caregivers
+- **Self-hostable**: Run your own instance if you prefer
+
+### 🌐 Community-Driven
+- **Open-source**: Built by the community, for the community
+- **Transparent**: All code is publicly auditable
+- **Collaborative**: Bug fixes and features from open-source contributors
+
+---
+
+## Business Model
+
+### Sustainable, Not Surveillance
+
+Normogen's revenue will come from **user subscriptions**, not from using or selling data.
+
+**Why subscriptions?**
+- Aligns our incentives with user privacy
+- Funds ongoing development and maintenance
+- Provides predictable, sustainable revenue
+- No pressure to monetize user data
+
+**Why open-source?**
+- The architecture is complex enough that users will want to pay for a hosted service rather than setting it up themselves
+- Bug fixes and features from the open-source community offset potential lost income
+- Builds trust and transparency
+- Encourages community contributions
+
+### Target Audience
+
+#### Primary: Privacy-Conscious Individuals
+- Age: 25-45
+- Tech-savvy
+- Concerned about data privacy
+- Wants to track medications and health stats
+- Values control over their data
+
+#### Secondary: Family Caregivers
+- Age: 30-55
+- Managing health data for dependents (children, elderly)
+- Needs easy data sharing
+- Wants medication reminders
+- Manages family health history
+
+#### Tertiary: Health Enthusiasts
+- Age: 20-40
+- Tracks fitness, sleep, nutrition
+- Uses wearables and sensors
+- Wants data analytics and insights
+- Interested in health trends
+
+---
+
+## Architecture
+
+### Client-Server Architecture
+- **Server**: Linux Docker container (Rust backend)
+- **Clients**: Web application and mobile apps (iOS, Android)
+- **Database**: MongoDB 7.0 with encryption
