+# User Notification Preferences
+
+## Overview
+Individual users can now control their notification preferences across three channels: **Email**, **Push**, and **In-App** notifications.
+
+---
+
+## Features Implemented
+
+### ✅ Backend
+
+1. **Database Schema**
+   - Added three boolean fields to `users` table:
+     - `email_notifications_enabled` (default: true)
+     - `push_notifications_enabled` (default: true)
+     - `in_app_notifications_enabled` (default: true)
+   - Migration file: `20251203-add-user-notification-preferences.ts`
+
+2. **User Model Updates**
+   - `Re_Backend/src/models/User.ts`
+   - Added fields: `emailNotificationsEnabled`, `pushNotificationsEnabled`, `inAppNotificationsEnabled`
+
+3. **API Endpoints**
+   - **GET** `/api/v1/user/preferences/notifications` - Get current user's preferences
+   - **PUT** `/api/v1/user/preferences/notifications` - Update preferences
+   - Controller: `Re_Backend/src/controllers/userPreference.controller.ts`
+   - Routes: `Re_Backend/src/routes/userPreference.routes.ts`
+   - Validator: `Re_Backend/src/validators/userPreference.validator.ts`
+
+4. **Notification Service Enhancement**
+   - `Re_Backend/src/services/notification.service.ts`
+   - Now checks user preferences before sending notifications
+   - Respects individual channel settings (email, push, in-app)
+
+### ✅ Frontend
+
+1. **API Service**
+   - `Re_Figma_Code/src/services/userPreferenceApi.ts`
+   - Functions: `getNotificationPreferences()`, `updateNotificationPreferences()`
+
+2. **UI Component**
+   - `Re_Figma_Code/src/components/settings/NotificationPreferences.tsx`
+   - Beautiful card-based UI with toggle switches
+   - Real-time updates with loading states
+   - Success/error feedback
+
+3. **Settings Page Integration**
+   - `Re_Figma_Code/src/pages/Settings/Settings.tsx`
+   - Full-width notification preferences card
+   - Separate browser push registration button
+   - Available for both admin and regular users
+
+---
+
+## How It Works
+
+### User Experience
+
+1. **Navigate to Settings**
+   - User clicks on Settings in the navigation
+
+2. **View Notification Preferences**
+   - Top card shows three toggle switches:
+     - 📧 **Email Notifications** - Receive notifications via email
+     - 🔔 **Push Notifications** - Receive browser push notifications
+     - 💬 **In-App Notifications** - Show notifications within the application
+
+3. **Toggle Preferences**
+   - Click any switch to enable/disable that channel
+   - Changes are saved immediately
+   - Success message confirms the update
+
+4. **Register Browser for Push** (separate card)
+   - One-time setup per browser/device
+   - Requests browser permission
+   - Registers the browser endpoint for push notifications
+
+### System Behavior
+
+**When sending notifications:**
+
+```typescript
+// System checks user preferences
+if (user.inAppNotificationsEnabled) {
+  // Create in-app notification in database
+  // Emit socket event for real-time delivery
+}
+
+if (user.pushNotificationsEnabled) {
+  // Send browser push notification (if browser is registered)
+}
+
+if (user.emailNotificationsEnabled) {
+  // Send email notification (when implemented)
+}
+```
+
+**Benefits:**
+- ✅ Users have full control over notification channels
+- ✅ Reduces notification fatigue
+- ✅ Improves user experience
+- ✅ Respects user preferences while ensuring critical alerts are delivered
+
+---
+
+## API Documentation
+
+### Get Notification Preferences
+
+**Request:**
+```http
+GET /api/v1/user/preferences/notifications
+Authorization: Bearer <token>
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "data": {
+    "emailNotificationsEnabled": true,
+    "pushNotificationsEnabled": true,
+    "inAppNotificationsEnabled": true
+  }
+}
+```
+
+### Update Notification Preferences
+
+**Request:**
+```http
+PUT /api/v1/user/preferences/notifications
+Authorization: Bearer <token>
+Content-Type: application/json
+
+{
+  "emailNotificationsEnabled": false,
+  "pushNotificationsEnabled": true,
+  "inAppNotificationsEnabled": true
+}
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "message": "Notification preferences updated successfully",
+  "data": {
+    "emailNotificationsEnabled": false,
+    "pushNotificationsEnabled": true,
+    "inAppNotificationsEnabled": true
+  }
+}
+```
+
+---
+
+## Database Migration
+
+To apply the migration:
+
+```bash
+cd Re_Backend
+npm run migrate
+```
+
+This will add the three notification preference columns to the `users` table with default value `true` for all existing users.
+
+---
+
+## Admin Configuration vs User Preferences
+
+### Two Levels of Control:
+
+1. **System-Wide (Admin Only)**
+   - Settings → Configuration → Notification Rules
+   - `ENABLE_EMAIL_NOTIFICATIONS` - Master switch for email
+   - `ENABLE_PUSH_NOTIFICATIONS` - Master switch for push
+   - If admin disables a channel, it's disabled for ALL users
+
+2. **User-Level (Individual Users)**
+   - Settings → User Settings → Notification Preferences
+   - Users can disable channels for themselves
+   - User preferences are respected only if admin has enabled the channel
+
+### Logic:
+```
+Notification Sent = Admin Enabled AND User Enabled
+```
+
+---
+
+## Future Enhancements
+
+- [ ] Email notification implementation (currently just a preference toggle)
+- [ ] SMS notifications support
+- [ ] Granular notification types (e.g., only approval requests, only TAT alerts)
+- [ ] Quiet hours / Do Not Disturb schedules
+- [ ] Notification digest/batching preferences
+
+---
+
+## Testing Checklist
+
+- [x] User can view their notification preferences
+- [x] User can toggle email notifications on/off
+- [x] User can toggle push notifications on/off
+- [x] User can toggle in-app notifications on/off
+- [x] Notification service respects user preferences
+- [x] In-app notifications are not created if disabled
+- [x] Push notifications are not sent if disabled
+- [x] UI shows loading states during updates
+- [x] UI shows success/error messages
+- [x] Migration adds columns with correct defaults
+- [x] API endpoints require authentication
+- [x] Changes persist after logout/login
+
+---
