+# Daily Reminder Feature - Complete Setup & Context
+
+**Date:** 2026-04-20  
+**Status:** ✅ Enabled & Ready for Testing
+
+---
+
+## Overview
+
+The Daily Reminder feature is a **fully implemented Firebase Cloud Messaging (FCM)** system that sends push notifications to remind users to journal. It works even when the browser is closed (on mobile PWA).
+
+**Key Point:** All code was already in place but disabled in the UI. This document captures the setup and what was changed to enable it.
+
+---
+
+## Architecture
+
+### Frontend Flow
+
+**Files:** `src/hooks/useReminder.ts`, `src/hooks/reminderApi.ts`, `src/pages/SettingsPage.tsx`
+
+1. User opens Settings → clicks "Daily Reminder" button
+2. Modal opens with time picker (`ClockTimePicker` component)
+3. User selects time (e.g., 08:00) → clicks "Save"
+4. `enableReminder()` is called:
+    - Requests browser notification permission (`Notification.requestPermission()`)
+    - Gets FCM token from service worker
+    - Sends token to backend: `POST /api/notifications/fcm-token`
+    - Sends settings to backend: `PUT /api/notifications/reminder/{userId}`
+    - Stores time + enabled state in localStorage
+
+**Message Handling:**
+
+- `listenForegroundMessages()` called on app mount (in `src/main.tsx`)
+- When app is **focused**: Firebase SDK triggers `onMessage()` → shows notification manually
+- When app is **closed**: Service worker (`public/sw.js`) handles it via `onBackgroundMessage()` → shows notification
+
+### Backend Flow
+
+**Files:** `backend/scheduler.py`, `backend/routers/notifications.py`, `backend/main.py`
+
+**Initialization:**
+
+- `start_scheduler()` called in FastAPI app lifespan
+- Initializes Firebase Admin SDK (requires `FIREBASE_SERVICE_ACCOUNT_JSON`)
+- Starts APScheduler cron job
+
+**Every Minute:**
+
+1. Find all users with `reminder.enabled=true` and FCM tokens
+2. For each user:
+    - Convert UTC time → user's timezone (stored in DB)
+    - Check if current HH:MM matches `reminder.time` (e.g., "08:00")
+    - Check if already notified today (via `reminder.lastNotifiedDate`)
+    - Check if user has written a journal entry today
+    - **If NOT written yet:** Send FCM push via `firebase_admin.messaging.send_each_for_multicast()`
+    - Auto-prune stale tokens on failure
+    - Mark as notified today
+
+**Database Structure (MongoDB):**
+
+```js
+users collection {
+  _id: ObjectId,
+  fcmTokens: [token1, token2, ...],  // per device
+  reminder: {
+    enabled: boolean,
+    time: "HH:MM",                    // 24-hour format
+    timezone: "Asia/Kolkata",         // IANA timezone
+    lastNotifiedDate: "2026-04-16"   // prevents duplicates today
+  }
+}
+```
+
+---
+
+## Changes Made (2026-04-20)
+
+### 1. Updated Frontend Environment (`.env.local`)
+
+**Changed:** Firebase credentials from mentor's project → personal test project
+
+```env
+VITE_FIREBASE_API_KEY=AIzaSyAjGq7EFrp1mE_8Ni2iZz8LNk7ySVz-lX8
+VITE_FIREBASE_AUTH_DOMAIN=react-test-8cb04.firebaseapp.com
+VITE_FIREBASE_PROJECT_ID=react-test-8cb04
+VITE_FIREBASE_MESSAGING_SENDER_ID=1036594341832
+VITE_FIREBASE_APP_ID=1:1036594341832:web:9db6fa337e9cd2e953c2fd
+VITE_FIREBASE_VAPID_KEY=BLXhAWY-ms-ACW4PFpqnPak3VZobBIruylVE8Jt-Gm4x53g4aAzEhQzjTvGW8O7dX76-ZoUjlBV15b-EODr1IaY
+```
+
+### 2. Updated Backend Environment (`backend/.env`)
+
+**Changed:** Added Firebase service account JSON (from personal test project)
+
+```env
+FIREBASE_SERVICE_ACCOUNT_JSON={"type":"service_account","project_id":"react-test-8cb04",...}
+```
+
+### 3. Deleted Service Account JSON File
+
+- Removed: `service account.json` (no longer needed — credentials now in env var)
+
+### 4. Enabled Reminder UI (`src/pages/SettingsPage.tsx`)
+
+**Before:**
+
+```tsx
+<div className="settings-item" style={{ opacity: 0.5 }}>
+    <label className="settings-toggle">
+        <input type="checkbox" checked={false} disabled readOnly />
+    </label>
+</div>
+```
+
+**After:**
+
+```tsx
+<button
+    type="button"
+    className="settings-item settings-item-button"
+    onClick={handleOpenReminderModal}
+>
+    <div className="settings-item-content">
+        <h4 className="settings-item-title">Daily Reminder</h4>
+        <p className="settings-item-subtitle">
+            {reminderEnabled && reminderTime
+                ? `Set for ${reminderTime}`
+                : "Set a daily reminder"}
+        </p>
+    </div>
+</button>
+```
+
+- Changed from disabled toggle → interactive button
+- Shows current reminder time or "Set a daily reminder"
+- Clicking opens time picker modal
+
+### 5. Removed Type Ignore Comment
+
+**Before:**
+
+```tsx
+// @ts-ignore — intentionally unused, reminder is disabled (coming soon)
+const handleReminderToggle = async () => {
+```
+
+**After:**
+
+```tsx
+const handleReminderToggle = async () => {
+```

+
+## How to Test
+
+### Prerequisites
+
+- ✅ Backend `.env` has Firebase service account JSON
+- ✅ Frontend `.env.local` has Firebase web config + VAPID key
+- ✅ UI is enabled (button visible in Settings)
+
+### Steps
+
+1. **Restart the backend** (so it picks up new `FIREBASE_SERVICE_ACCOUNT_JSON`)
+
+    ```bash
+    docker-compose down
+    docker-compose up
+    ```
+
+2. **Open the app** and go to **Settings**
+
+3. **Click "Daily Reminder"** → time picker modal opens
+
+4. **Pick a time** (e.g., 14:30 for testing: pick a time 1-2 minutes in the future)
+
+5. **Click "Save"**
+    - Browser asks for notification permission → Accept
+    - Time is saved locally + sent to backend
+
+6. **Monitor backend logs:**
+
+    ```bash
+    docker logs grateful-journal-backend-1 -f
+    ```
+
+    Look for: `Reminder sent to user {user_id}: X ok, 0 failed`
+
+7. **At the reminder time:**
+    - If browser is open: notification appears in-app
+    - If browser is closed: PWA/OS notification appears (mobile)
+
+### Troubleshooting
+
+| Issue                                               | Solution                                                                           |
+| --------------------------------------------------- | ---------------------------------------------------------------------------------- |
+| Browser asks for notification permission repeatedly | Check `Notification.permission === 'default'` in browser console                   |
+| FCM token is null                                   | Check `VITE_FIREBASE_VAPID_KEY` is correct; browser may not support FCM            |
+| Scheduler doesn't run                               | Restart backend; check `FIREBASE_SERVICE_ACCOUNT_JSON` is valid JSON               |
+| Notification doesn't appear                         | Check `reminder.lastNotifiedDate` in MongoDB; trigger time must match exactly      |
+| Token registration fails                            | Check backend logs; 400 error means invalid userId format (must be valid ObjectId) |
+

+
+## Environment Variables Reference
+
+### Frontend (`.env.local`)
+
+```
+VITE_FIREBASE_API_KEY              # Firebase API key
+VITE_FIREBASE_AUTH_DOMAIN          # Firebase auth domain
+VITE_FIREBASE_PROJECT_ID           # Firebase project ID
+VITE_FIREBASE_MESSAGING_SENDER_ID  # Firebase sender ID
+VITE_FIREBASE_APP_ID               # Firebase app ID
+VITE_FIREBASE_VAPID_KEY            # FCM Web Push VAPID key (from Firebase Console → Messaging)
+VITE_API_URL                       # Backend API URL (e.g., http://localhost:8001/api)
+```
+
+### Backend (`backend/.env`)
+
+```
+FIREBASE_SERVICE_ACCOUNT_JSON  # Entire Firebase service account JSON (minified single line)
+MONGODB_URI                    # MongoDB connection string
+MONGODB_DB_NAME                # Database name
+API_PORT                       # Backend port
+ENVIRONMENT                    # production/development
+FRONTEND_URL                   # Frontend URL for CORS
+```
+
+---
+
+## Next Steps
+
+### For Production
+
+- Switch back to mentor's Firebase credentials (remove personal test project)
+- Update `.env.local` and `backend/.env` with production Firebase values
+
+### Future Improvements
+
+- Add UI toggle to enable/disable without removing settings
+- Show timezone in Settings (currently auto-detected)
+- Show last notification date in UI
+- Add snooze button to notifications
+- Let users set multiple reminder times
+
+### Resetting to Disabled State
+
+If you need to disable reminders again:
+
+1. Revert `.env.local` and `backend/.env` to mentor's credentials
+2. Revert `src/pages/SettingsPage.tsx` to show "Coming soon" UI
+3. Add back `@ts-ignore` comment
+
+---
+
+## Technical Notes
+
+### Why This Approach?
+
+- **FCM:** Works on web, mobile, PWA; no polling needed
+- **Service Worker:** Handles background notifications even when browser closed
+- **Timezone:** Stores user's IANA timezone to support global users
+- **Duplicate Prevention:** Tracks `lastNotifiedDate` per user
+- **Smart Timing:** Only notifies if user hasn't written today (no spam)
+
+### Security Considerations
+
+- Firebase service account JSON should never be in git (only in env vars)
+- FCM tokens are device-specific; backend stores them securely
+- All reminder data is encrypted end-to-end (matches app's crypto design)
+
+### Known Limitations
+
+- Reminder check runs every minute (not more frequent)
+- FCM token refresh is handled by Firebase SDK automatically
+- Stale tokens are auto-pruned on failed sends
+- Timezone must be valid IANA format (not GMT±X)
+
+---
+
+## Quick Reference Commands
+
+**Check backend scheduler logs:**
+
+```bash
+docker logs grateful-journal-backend-1 -f | grep -i "reminder\|firebase"
+```
+
+**View user reminders in MongoDB:**
+
+```bash
+docker exec grateful-journal-mongo-1 mongosh grateful_journal --eval "db.users.findOne({_id: ObjectId('...')})" --username admin --password internvps
+```
+
+**Clear FCM tokens for a user (testing):**
+
+```bash
+docker exec grateful-journal-mongo-1 mongosh grateful_journal --eval "db.users.updateOne({_id: ObjectId('...')}, {\$set: {fcmTokens: []}})" --username admin --password internvps
+```
