-# React + TypeScript + Vite
+# Grateful Journal
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+A minimal, private-first gratitude journaling app. Write what you're grateful for. Nothing more, nothing less.
 
-Currently, two official plugins are available:
+---
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+## What is this?
 
-## React Compiler
+Grateful Journal is a personal journaling app built around one simple habit — writing down what you're grateful for each day. No social feeds, no algorithms, no sharing. Just you and your thoughts.
 
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+The app is designed to get out of your way. Open it, write a sentence or a page, save it. Done.
 
-## Expanding the ESLint configuration
+---
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+## Privacy by Design
 
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
+Every journal entry is **end-to-end encrypted** before it ever leaves your device. The server stores only ciphertext — it has no ability to read your entries, even if compromised.
 
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
+**How it works:**
 
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
+- You sign in with Google. Your Firebase UID is used to derive a 256-bit master key via Argon2i key derivation.
+- Your entries are encrypted client-side using XSalsa20-Poly1305 (libsodium) before being sent to the backend.
+- The backend stores only the encrypted blob (ciphertext + nonce). No title, no content, no plaintext.
+- Decryption happens entirely in your browser using the in-memory master key.
+- Logging out clears the key from memory. Your device key persists so the next login is seamless.
+- The same Google account works across devices — the master key is deterministically derived from your credentials, so your entries are always accessible.
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+**What the server can never see:** your entry titles, your entry content, anything you write.
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
+---
 
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
+## Features
+
+- **Write** — A clean, distraction-free writing area. Give your entry a title and write your thoughts.
+- **History** — A calendar view of all your past entries. Green dots mark the days you wrote. Tap a date to read what you wrote.
+- **Settings** — Change your display name, profile photo, and app theme (light/dark).
+- **Onboarding tour** — A guided walkthrough on first login to show you around.
+- **Encrypted storage** — Every entry encrypted end-to-end with industry-standard cryptography.

+## Tech
+
+| Layer | What |
+|-------|------|
+| Frontend | React 19 + TypeScript, Vite |
+| Auth | Firebase (Google Sign-In) |
+| Encryption | libsodium — XSalsa20-Poly1305, Argon2i |
+| Backend | FastAPI (Python) |
+| Database | MongoDB |
+| Deployment | Docker (3 containers — nginx, FastAPI, MongoDB) |
+

+
+## Philosophy
+
+Most journaling apps are over-engineered. Prompts, streaks, mood tracking, sharing — all noise. This app exists for one thing: a private place to write what you're grateful for.
+
+The encryption isn't a feature, it's a requirement. A journal is personal. It should stay that way.
