+# Normogen
+
+## Naming
+
+Codename, coming from mapudungun, related to Balanced Life. Commercial name to be defined
+
+## 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 there, use the data to help the user, not for profit.
+From reminding about medication, to comparing data changes over time, and finding emerging patterns.
+
+## Income
+
+It will come from subscriptions from users, not from using the data.
+Even if open-source, the architecture is complicated enough that users will want to pay a subscription rather than setting it all up themselves. And the bugfixing coming from open-source users should offset the lost income.
+
+## Architecture
+
+Client-server architecture, server running on linux docker, clients via web or phone apps (iOS and Android)
+
+Rust for the server backend. Nodejs for web server. Clients will be on whatever is best for each platform, which can reuse the web when possible.
+
+Data has to be encrypted on storage, only accessible to the user, on the server and on the phone apps.
+It is important to be able to share specific bits of data with external users. (at first, accessed by an expiring link). Therefore, the encryption has to be made in a way that a limited password can access some of the data.
+
+It will be open-sourced, both server and clients.
+
+### Plugins
+
+Mostly for import and export of data
+
+
+## Application Features
+
+### User structure
+
+- User login
+- Person, which may not be the logged in user. eg. recording data of a child
+- Family structure (eg. parents, children, elderly under care, etc.)
+
+### General
+
+- Lab results storage
+- Medication
+  - Pill shape
+  - Length of take
+  - Timetable
+  - Drug composition
+- General health statistics, such as weight over time, height, age
+- Medical appointments
+- Regular checkouts
+- Period tracking
+- Pregnancy
+- Dental information
+- Illness records
+
+
+### Phone app
+
+- Pill reminder
+- QR code reader, for access to lab results and others
+- Health statistics from the phone and connected devices, such as:
+  - steps
+  - physical activity
+  - Breathing
+  - Sleep patterns
+  - Blood pressure
+  - Temperature, etc
+- Sync back to the main server at regular intervals
+- Instant nuke option, to delete all data instantly (for privacy)
+
+### Lab Results
+
+Lab results are not standard format, so there must be a plugin structure that allows to convert data from specific labs
+
+### Sensors
+
+Most sensors will have a common interface or data will be accessable through the phone's Health API, but there might be cases where a plugin to convert data is needed
