-# Daily.co Migration Implementation Status
-
-## Completed Components
-
-### 1. Platform Abstraction Layer (`server/reflector/video_platforms/`)
- **base.py**: Abstract interface defining all platform operations
- **whereby.py**: Whereby implementation wrapping existing functionality
- **daily.py**: Daily.co client implementation (ready for testing when credentials available)
- **mock.py**: Mock implementation for unit testing
- **registry.py**: Platform registration and discovery
- **factory.py**: Factory methods for creating platform clients
-
-### 2. Database Updates
- **Models**: Added `platform` field to Room and Meeting tables
- **Migration**: Created migration `20250801180012_add_platform_support.py`
- **Controllers**: Updated to handle platform field
-
-### 3. Configuration
- **Settings**: Added Daily.co configuration variables
- **Feature Flags**:
-  - `DAILY_MIGRATION_ENABLED`: Master switch for migration
-  - `DAILY_MIGRATION_ROOM_IDS`: List of specific rooms to migrate
-  - `DEFAULT_VIDEO_PLATFORM`: Default platform when migration enabled
-
-### 4. Backend API Updates
- **Room Creation**: Now assigns platform based on feature flags
- **Meeting Creation**: Uses platform abstraction instead of direct Whereby calls
- **Response Models**: Include platform field
- **Webhook Handler**: Added Daily.co webhook endpoint at `/v1/daily_webhook`
-
-### 5. Frontend Components (`www/app/[roomName]/components/`)
- **RoomContainer.tsx**: Platform-agnostic container that routes to appropriate component
- **WherebyRoom.tsx**: Extracted existing Whereby functionality with consent management
- **DailyRoom.tsx**: Daily.co implementation using DailyIframe
- **Dependencies**: Added `@daily-co/daily-js` and `@daily-co/daily-react`
-
-## How It Works
-
-1. **Platform Selection**:
-   - If `DAILY_MIGRATION_ENABLED=false` → Always use Whereby
-   - If enabled and room ID in `DAILY_MIGRATION_ROOM_IDS` → Use Daily
-   - Otherwise → Use `DEFAULT_VIDEO_PLATFORM`
-
-2. **Meeting Creation Flow**:
-   ```python
-   platform = get_platform_for_room(room.id)
-   client = create_platform_client(platform)
-   meeting_data = await client.create_meeting(...)
-   ```
-
-3. **Testing Without Credentials**:
-   - Use `platform="mock"` in tests
-   - Mock client simulates all operations
-   - No external API calls needed
-
-## Next Steps
-
-### When Daily.co Credentials Available:
-
-1. **Set Environment Variables**:
-   ```bash
-   DAILY_API_KEY=your-key
-   DAILY_WEBHOOK_SECRET=your-secret
-   DAILY_SUBDOMAIN=your-subdomain
-   AWS_DAILY_S3_BUCKET=your-bucket
-   AWS_DAILY_ROLE_ARN=your-role
-   ```
-
-2. **Run Database Migration**:
-   ```bash
-   cd server
-   uv run alembic upgrade head
-   ```
-
-3. **Test Platform Creation**:
-   ```python
-   from reflector.video_platforms.factory import create_platform_client
-   client = create_platform_client("daily")
-   # Test operations...
-   ```
-
-### 6. Testing & Validation (`server/tests/`)
- **test_video_platforms.py**: Comprehensive unit tests for all platform clients
- **test_daily_webhook.py**: Integration tests for Daily.co webhook handling
- **utils/video_platform_test_utils.py**: Testing utilities and helpers
- **Mock Testing**: Full test coverage using mock platform client
- **Webhook Testing**: HMAC signature validation and event processing tests
-
-### All Core Implementation Complete ✅
-
-The Daily.co migration implementation is now complete and ready for testing with actual credentials:
-
- ✅ Platform abstraction layer with factory pattern
- ✅ Database schema migration
- ✅ Feature flag system for gradual rollout
- ✅ Backend API integration with webhook handling
- ✅ Frontend platform-agnostic components
- ✅ Comprehensive test suite with >95% coverage
-
-## Daily.co Webhook Integration
-
-### Webhook Configuration
-
-Daily.co webhooks are configured via API (no dashboard interface). Use the Daily.co REST API to set up webhook endpoints:
-
-```bash
-# Configure webhook endpoint
-curl -X POST https://api.daily.co/v1/webhook-endpoints \
-  -H "Authorization: Bearer ${DAILY_API_KEY}" \
-  -H "Content-Type: application/json" \
-  -d '{
-    "url": "https://yourdomain.com/v1/daily_webhook",
-    "events": [
-      "participant.joined",
-      "participant.left",
-      "recording.started",
-      "recording.ready-to-download",
-      "recording.error"
-    ]
-  }'
-```
-
-### Webhook Event Examples
-
-**Participant Joined:**
-```json
-{
-  "type": "participant.joined",
-  "id": "evt_participant_joined_1640995200",
-  "ts": 1640995200000,
-  "data": {
-    "room": {"name": "test-room-123-abc"},
-    "participant": {
-      "id": "participant-123",
-      "user_name": "John Doe",
-      "session_id": "session-456"
-    }
-  }
-}
-```
-
-**Recording Ready:**
-```json
-{
-  "type": "recording.ready-to-download",
-  "id": "evt_recording_ready_1640995200",
-  "ts": 1640995200000,
-  "data": {
-    "room": {"name": "test-room-123-abc"},
-    "recording": {
-      "id": "recording-789",
-      "status": "finished",
-      "download_url": "https://bucket.s3.amazonaws.com/recording.mp4",
-      "start_time": "2025-01-01T10:00:00Z",
-      "duration": 1800
-    }
-  }
-}
-```
-
-### Webhook Signature Verification
-
-Daily.co uses HMAC-SHA256 for webhook verification:
-
-```python
-import hmac
-import hashlib
-
-def verify_daily_webhook(body: bytes, signature: str, secret: str) -> bool:
-    expected = hmac.new(secret.encode(), body, hashlib.sha256).hexdigest()
-    return hmac.compare_digest(expected, signature)
-```
-
-Signature is sent in the `X-Daily-Signature` header.
-
-### Recording Processing Flow
-
-1. **Daily.co Meeting Ends** → Recording processed
-2. **Webhook Fired** → `recording.ready-to-download` event
-3. **Webhook Handler** → Extracts download URL and recording ID
-4. **Background Task** → `process_recording_from_url.delay()` queued
-5. **Download & Process** → Audio downloaded, validated, transcribed
-6. **ML Pipeline** → Same processing as Whereby recordings
-
-```python
-# New Celery task for Daily.co recordings
-@shared_task
-@asynctask
-async def process_recording_from_url(recording_url: str, meeting_id: str, recording_id: str):
-    # Downloads from Daily.co URL → Creates transcript → Triggers ML pipeline
-    # Identical processing to S3-based recordings after download
-```
-
-## Testing the Current Implementation
-
-### Running the Test Suite
-
-```bash
-# Run all video platform tests
-uv run pytest tests/test_video_platforms.py -v
-
-# Run webhook integration tests
-uv run pytest tests/test_daily_webhook.py -v
-
-# Run with coverage
-uv run pytest tests/test_video_platforms.py tests/test_daily_webhook.py --cov=reflector.video_platforms --cov=reflector.views.daily
-```
-
-### Manual Testing with Mock Platform
-
-```python
-from reflector.video_platforms.factory import create_platform_client
-
-# Create mock client (no credentials needed)
-client = create_platform_client("mock")
-
-# Test operations
-from reflector.db.rooms import Room
-from datetime import datetime, timedelta
-
-mock_room = Room(id="test-123", name="Test Room", recording_type="cloud")
-meeting = await client.create_meeting(
-    room_name_prefix="test",
-    end_date=datetime.utcnow() + timedelta(hours=1),
-    room=mock_room
-)
-print(f"Created meeting: {meeting.room_url}")
-```
-
-### Testing Daily.co Recording Processing
-
-```python
-# Test webhook payload processing
-from reflector.views.daily import daily_webhook
-from reflector.worker.process import process_recording_from_url
-
-# Simulate webhook event
-event_data = {
-    "type": "recording.ready-to-download",
-    "id": "evt_123",
-    "ts": 1640995200000,
-    "data": {
-        "room": {"name": "test-room-123"},
-        "recording": {
-            "id": "rec-456",
-            "download_url": "https://daily.co/recordings/test.mp4"
-        }
-    }
-}
-
-# Test processing task (when credentials available)
-await process_recording_from_url(
-    recording_url="https://daily.co/recordings/test.mp4",
-    meeting_id="meeting-123",
-    recording_id="rec-456"
-)
-```
-
-## Architecture Benefits
-
-1. **Testable**: Mock implementation allows testing without external dependencies
-2. **Extensible**: Easy to add new platforms (Zoom, Teams, etc.)
-3. **Gradual Migration**: Feature flags enable room-by-room migration
-4. **Rollback Ready**: Can disable Daily.co instantly via feature flag

-# Daily.co Migration Plan - Feature Parity Approach
-
-## Overview
-
-This plan outlines a systematic migration from Whereby to Daily.co, focusing on **1:1 feature parity** without introducing new capabilities. The goal is to improve code quality, developer experience, and platform reliability while maintaining the exact same user experience and processing pipeline.
-
-## Migration Principles
-
-1. **No Breaking Changes**: Existing recordings and workflows must continue to work
-2. **Feature Parity First**: Match current functionality exactly before adding improvements
-3. **Gradual Rollout**: Use feature flags to control migration per room/user
-4. **Minimal Risk**: Keep changes isolated and reversible

-
-### 1.4 Daily.co API Client
-**Owner**: Backend Developer
-
- [x] Create `server/reflector/video_platforms/` with core functionality:
-  - `create_meeting()` - Match Whereby's meeting creation
-  - `get_room_sessions()` - Room status checking
-  - `delete_room()` - Cleanup functionality
- [x] Add comprehensive error handling
- [ ] Write unit tests for API client (Phase 4)
-

- [x] Better error handling with platform abstraction
- [x] Cleaner React component structure with platform routing
-
-## Rollback Plan
-
-If issues arise during migration:
-
-1. **Immediate**: Disable Daily.co feature flag
-2. **Short-term**: Revert frontend components via git
-3. **Database**: Platform field defaults to 'whereby'
-4. **Full rollback**: Remove Daily.co code (isolated in separate files)
-
-## Post-Migration Opportunities
-
-Once feature parity is achieved and stable:
-
-1. **Raw-tracks recording** for better diarization
-2. **Real-time transcription** via Daily.co API
-3. **Advanced analytics** and participant insights
-4. **Custom UI** improvements
-5. **Performance optimizations**
-
-## Phase Dependencies
-
- ✅ Backend Integration requires Foundation to be complete
- ✅ Frontend Migration can start after Backend API client is ready
- ✅ Testing requires both Backend and Frontend to be complete
- ⏳ Rollout begins after successful testing (pending Daily.co credentials)
-
-## Risk Matrix
-
-| Risk | Probability | Impact | Mitigation |
-|------|-------------|---------|------------|
-| API differences | Low | Medium | Abstraction layer |
-| Recording format issues | Low | High | Extensive testing |
-| User confusion | Low | Low | Gradual rollout |
-| Performance degradation | Low | Medium | Monitoring |
-
-## Communication Plan
-
-1. **Week 1**: Announce migration plan to team
-2. **Week 2**: Update on development progress
-3. **Beta Launch**: Email to beta users
-4. **Full Launch**: User notification (if UI changes)
-5. **Post-Launch**: Success metrics report
-
---
-
-## Implementation Status: COMPLETE ✅
-
-All development phases are complete and ready for live testing:
-
-✅ **Phase 1**: Foundation (database, config, feature flags)
-✅ **Phase 2**: Backend Integration (API clients, webhooks)
-✅ **Phase 3**: Frontend Migration (platform components)
-✅ **Phase 4**: Testing & Validation (comprehensive test suite)
-
-**Next Steps**: Obtain Daily.co credentials and run live integration testing before gradual rollout.
-
-This implementation prioritizes stability and risk mitigation through a phased approach. The modular design allows for easy adjustments based on live testing findings.

+## What is Reflector?
+
+Reflector is a web application that utilizes local models to process audio content, providing:
+
+- **Real-time Transcription**: Convert speech to text using [Whisper](https://github.com/openai/whisper) (multi-language) or [Parakeet](https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2) (English) models
+- **Speaker Diarization**: Identify and label different speakers using [Pyannote](https://github.com/pyannote/pyannote-audio) 3.1
+- **Live Translation**: Translate audio content in real-time to many languages with [Facebook Seamless-M4T](https://github.com/facebookresearch/seamless_communication)
+- **Topic Detection & Summarization**: Extract key topics and generate concise summaries using LLMs
+- **Meeting Recording**: Create permanent records of meetings with searchable transcripts
+
+Currently we provide [modal.com](https://modal.com/) gpu template to deploy.
+
 ## Background

 The project architecture consists of three primary components:

- **Front-End**: NextJS React project hosted on Vercel, located in `www/`.
 - **Back-End**: Python server that offers an API and data persistence, found in `server/`.
- **GPU implementation**: Providing services such as speech-to-text transcription, topic generation, automated summaries, and translations. Most reliable option is Modal deployment

-# Whereby to Daily.co Migration Feasibility Analysis
-
-## Executive Summary
-
-After analysis of the current Whereby integration and Daily.co's capabilities, migrating to Daily.co is technically feasible. The migration can be done in phases:
-
-1. **Phase 1**: Feature parity with current implementation (standard cloud recording)
-2. **Phase 2**: Enhanced capabilities with raw-tracks recording for improved diarization
-
-### Current Implementation Analysis
-
-Based on code review:
- **Webhook handling**: The current webhook handler (`server/reflector/views/whereby.py`) only tracks `num_clients`, not individual participants
- **Focus management**: The frontend has 70+ lines managing focus between Whereby embed and consent dialog
- **Participant tracking**: No participant names or IDs are captured in the current implementation
- **Recording type**: Cloud recording to S3 in MP4 format with mixed audio
-
-### Migration Approach
-
-**Phase 1**: 1:1 feature replacement maintaining current functionality:
- Standard cloud recording (same as current Whereby implementation)
- Same recording workflow: Video platform → S3 → Reflector processing
- No changes to existing diarization or transcription pipeline
-
-**Phase 2**: Enhanced capabilities (future implementation):
- Raw-tracks recording for speaker-separated audio
- Improved diarization with participant-to-audio mapping
- Per-participant transcription accuracy
-
-## Current Whereby Integration Analysis
-
-### Backend Integration
-
-#### Core API Module (`server/reflector/whereby.py`)
- **Meeting Creation**: Creates rooms with S3 recording configuration
- **Session Monitoring**: Tracks meeting status via room sessions API
- **Logo Upload**: Handles branding for meetings
- **Key Functions**:
-  ```python
-  create_meeting(room_name, logo_s3_url) -> dict
-  monitor_room_session(meeting_link) -> dict
-  upload_logo(file_stream, content_type) -> str
-  ```
-
-#### Webhook Handler (`server/reflector/views/whereby.py`)
- **Endpoint**: `/v1/whereby_webhook`
- **Security**: HMAC signature validation
- **Events Handled**:
-  - `room.participant.joined`
-  - `room.participant.left`
- **Pain Point**: Delay between actual join/leave and webhook delivery
-
-#### Room Management (`server/reflector/views/rooms.py`)
- Creates meetings via Whereby API
- Stores meeting data in database
- Manages recording lifecycle
-
-### Frontend Integration
-
-#### Main Room Component (`www/app/[roomName]/page.tsx`)
- Uses `@whereby.com/browser-sdk` (v3.3.4)
- Implements custom `<whereby-embed>` element
- Handles recording consent
- Focus management for accessibility
-
-#### Configuration
- Environment Variables:
-  - `WHEREBY_API_URL`, `WHEREBY_API_KEY`, `WHEREBY_WEBHOOK_SECRET`
-  - AWS S3 credentials for recordings
- Recording workflow: Whereby → S3 → Reflector processing pipeline
-
-## Daily.co Capabilities Analysis
-
-### REST API Features
-
-#### Room Management
-```
-POST /rooms - Create room with configuration
-GET /rooms/:name/presence - Real-time participant data
-POST /rooms/:name/recordings/start - Start recording
-```
-
-#### Recording Options
-```json
-{
-  "enable_recording": "raw-tracks"  // Key feature for diarization
-}
-```
-
-#### Webhook Events
- `participant.joined` / `participant.left`
- `waiting-participant.joined` / `waiting-participant.left`
- `recording.started` / `recording.ready-to-download`
- `recording.error`
-
-### React SDK (@daily-co/daily-react)
-
-#### Modern Hook-based Architecture
-```jsx
-// Participant tracking
-const participantIds = useParticipantIds({ filter: 'remote' });
-const [username, videoState] = useParticipantProperty(id, ['user_name', 'tracks.video.state']);
-
-// Recording management
-const { isRecording, startRecording, stopRecording } = useRecording();
-
-// Real-time participant data
-const participants = useParticipants();
-```
-
-## Feature Comparison
-
-| Feature | Whereby | Daily.co |
-|---------|---------|----------|
-| **Room Creation** | REST API | REST API |
-| **Recording Types** | Cloud (MP4) | Cloud (MP4), Local, Raw-tracks |
-| **S3 Integration** | Direct upload | Direct upload with IAM roles |
-| **Frontend Integration** | Custom element | React hooks or iframe |
-| **Webhooks** | HMAC verified | HMAC verified |
-| **Participant Data** | Via webhooks | Via webhooks + Presence API |
-| **Recording Trigger** | Automatic/manual | Automatic/manual |

-## Migration Plan
-
-### Phase 1: Backend API Client
-
-#### 1.1 Create Daily.co API Client (`server/reflector/daily.py`)

-
-### Phase 2: Frontend Components
-
-#### 2.1 Replace Whereby SDK with Daily React
-
-First, update dependencies:
-```bash
-# Remove Whereby
-yarn remove @whereby.com/browser-sdk
-
-# Add Daily.co
-yarn add @daily-co/daily-react @daily-co/daily-js

-    </DailyProvider>
-  );
-}
-
-### Phase 3: Testing & Validation
-
-For Phase 1 (feature parity), the existing processing pipeline remains unchanged:
-
-1. Daily.co records meeting to S3 (same as Whereby)
-2. Webhook notifies when recording is ready
-3. Existing pipeline downloads and processes the MP4 file
-4. Current diarization and transcription tools continue to work
-
-Key validation points:
- Recording format matches (MP4 with mixed audio)
- S3 paths are compatible
- Processing pipeline requires no changes
- Transcript quality remains the same
-
-## Future Enhancement: Raw-Tracks Recording (Phase 2)
-
-### Raw-Tracks Processing for Enhanced Diarization
-
-Daily.co's raw-tracks recording provides individual audio streams per participant, enabling:
-
-```python
-@shared_task
-def process_daily_raw_tracks(meeting_id: str, recording_id: str, tracks: list):
-    """Process Daily.co raw-tracks with perfect speaker attribution."""
-
-    for track in tracks:
-        participant_id = track["participant_id"]
-        participant_name = track["participant_name"]
-        track_url = track["download_url"]
-
-        # Download individual participant audio
-        response = download_track(track_url)
-
-        # Process with known speaker identity
-        transcript = transcribe_audio(
-            audio_data=response.content,
-            speaker_id=participant_id,
-            speaker_name=participant_name
-        )
-
-        # Store with accurate speaker mapping
-        save_transcript_segment(
-            meeting_id=meeting_id,
-            speaker_id=participant_id,
-            text=transcript.text,
-            timestamps=transcript.timestamps
-        )
-```
-
-### Benefits of Raw-Tracks (Future)
-
-1. **Deterministic Speaker Attribution**: Each audio track is already speaker-separated
-2. **Improved Transcription Accuracy**: Clean audio without cross-talk
-3. **Parallel Processing**: Process multiple speakers simultaneously
-4. **Better Metrics**: Accurate talk-time per participant
-
-### Phase 4: Database & Configuration
-
-#### 4.1 Environment Variable Updates
-
-Update `.env` files:
-
-```bash
-# Remove Whereby variables
-# WHEREBY_API_URL=https://api.whereby.dev/v1
-# WHEREBY_API_KEY=your-whereby-key
-# WHEREBY_WEBHOOK_SECRET=your-whereby-secret
-# AWS_WHEREBY_S3_BUCKET=whereby-recordings
-# AWS_WHEREBY_ACCESS_KEY_ID=whereby-key
-# AWS_WHEREBY_ACCESS_KEY_SECRET=whereby-secret
-
-# Add Daily.co variables
-DAILY_API_KEY=your-daily-api-key
-DAILY_WEBHOOK_SECRET=your-daily-webhook-secret
-AWS_DAILY_S3_BUCKET=daily-recordings
-AWS_DAILY_ROLE_ARN=arn:aws:iam::123456789:role/daily-recording-role
-AWS_REGION=us-west-2
-```
-
-#### 4.2 Database Migration
-
-```sql
-- Alembic migration to support Daily.co
-- server/alembic/versions/xxx_migrate_to_daily.py
-
-def upgrade():
-    # Add platform field to support gradual migration
-    op.add_column('rooms', sa.Column('platform', sa.String(), server_default='whereby'))
-    op.add_column('meetings', sa.Column('platform', sa.String(), server_default='whereby'))
-
-    # No other schema changes needed for feature parity
-
-def downgrade():
-    op.drop_column('meetings', 'platform')
-    op.drop_column('rooms', 'platform')
-```
-
-#### 4.3 Settings Update (`server/reflector/settings.py`)
-
-```python
-class Settings(BaseSettings):
-    # Remove Whereby settings
-    # WHEREBY_API_URL: str = "https://api.whereby.dev/v1"
-    # WHEREBY_API_KEY: str
-    # WHEREBY_WEBHOOK_SECRET: str
-    # AWS_WHEREBY_S3_BUCKET: str
-    # AWS_WHEREBY_ACCESS_KEY_ID: str
-    # AWS_WHEREBY_ACCESS_KEY_SECRET: str
-
-    # Add Daily.co settings
-    DAILY_API_KEY: str
-    DAILY_WEBHOOK_SECRET: str
-    AWS_DAILY_S3_BUCKET: str
-    AWS_DAILY_ROLE_ARN: str
-    AWS_REGION: str = "us-west-2"
-
-    # Daily.co room URL pattern
-    DAILY_ROOM_URL_PATTERN: str = "https://{subdomain}.daily.co/{room_name}"
-    DAILY_SUBDOMAIN: str = "reflector"  # Your Daily.co subdomain
-```
-
-## Technical Differences
-
-### Phase 1 Implementation
-1. **Frontend**: Replace `<whereby-embed>` custom element with Daily.co React components or iframe
-2. **Backend**: Create Daily.co API client matching Whereby's functionality
-3. **Webhooks**: Map Daily.co events to existing database operations
-4. **Recording**: Maintain same MP4 format and S3 storage
-
-### Phase 2 Capabilities (Future)
-1. **Raw-tracks recording**: Individual audio streams per participant
-2. **Presence API**: Real-time participant data without webhook delays
-3. **Transcription API**: Built-in transcription services
-4. **Advanced recording options**: Multiple formats and layouts
-
-## Risks and Mitigation
-
-### Risk 1: API Differences
- **Mitigation**: Create abstraction layer to minimize changes
- Comprehensive testing of all endpoints
-
-### Risk 2: Recording Format Changes
- **Mitigation**: Build adapter for raw-tracks processing
- Maintain backward compatibility during transition
-
-### Risk 3: User Experience Changes
- **Mitigation**: A/B testing with gradual rollout
- Feature parity checklist before full migration
-
-## Recommendation
-
-Migration to Daily.co is technically feasible and can be implemented in phases:
-
-### Phase 1: Feature Parity
- Replace Whereby with Daily.co maintaining exact same functionality
- Use standard cloud recording (MP4 to S3)
- No changes to processing pipeline
-
-### Phase 2: Enhanced Capabilities (Future)
- Enable raw-tracks recording for improved diarization
- Implement participant-level audio processing
- Add real-time features using Presence API
-
-## Next Steps
-
-1. Set up Daily.co account and obtain API credentials
-2. Implement feature flag system for gradual migration
-3. Create Daily.co API client matching Whereby functionality
-4. Update frontend to support both platforms
-5. Test thoroughly before rollout

+# Data Retention and Cleanup
+
+## Overview
+
+For public instances of Reflector, a data retention policy is automatically enforced to delete anonymous user data after a configurable period (default: 7 days). This ensures compliance with privacy expectations and prevents unbounded storage growth.
+
+## Configuration
+
+### Environment Variables
+
+- `PUBLIC_MODE` (bool): Must be set to `true` to enable automatic cleanup
+- `PUBLIC_DATA_RETENTION_DAYS` (int): Number of days to retain anonymous data (default: 7)
+
+### What Gets Deleted
+
+When data reaches the retention period, the following items are automatically removed:
+
+1. **Transcripts** from anonymous users (where `user_id` is NULL):
+   - Database records
+   - Local files (audio.wav, audio.mp3, audio.json waveform)
+   - Storage files (cloud storage if configured)
+
+## Automatic Cleanup
+
+### Celery Beat Schedule
+
+When `PUBLIC_MODE=true`, a Celery beat task runs daily at 3 AM to clean up old data:
+
+```python
+# Automatically scheduled when PUBLIC_MODE=true
+"cleanup_old_public_data": {
+    "task": "reflector.worker.cleanup.cleanup_old_public_data",
+    "schedule": crontab(hour=3, minute=0),  # Daily at 3 AM
+}
+```
+
+### Running the Worker
+
+Ensure both Celery worker and beat scheduler are running:
+
+```bash
+# Start Celery worker
+uv run celery -A reflector.worker.app worker --loglevel=info
+
+# Start Celery beat scheduler (in another terminal)
+uv run celery -A reflector.worker.app beat
+```
+
+## Manual Cleanup
+
+For testing or manual intervention, use the cleanup tool:
+
+```bash
+# Delete data older than 7 days (default)
+uv run python -m reflector.tools.cleanup_old_data
+
+# Delete data older than 30 days
+uv run python -m reflector.tools.cleanup_old_data --days 30
+```
+
+Note: The manual tool uses the same implementation as the Celery worker task to ensure consistency.
+
+## Important Notes
+
+1. **User Data Deletion**: Only anonymous data (where `user_id` is NULL) is deleted. Authenticated user data is preserved.
+
+2. **Storage Cleanup**: The system properly cleans up both local files and cloud storage when configured.
+
+3. **Error Handling**: If individual deletions fail, the cleanup continues and logs errors. Failed deletions are reported in the task output.
+
+4. **Public Instance Only**: The automatic cleanup task only runs when `PUBLIC_MODE=true` to prevent accidental data loss in private deployments.
+
+## Testing
+
+Run the cleanup tests:
+
+```bash
+uv run pytest tests/test_cleanup.py -v
+```
+
+## Monitoring
+
+Check Celery logs for cleanup task execution:
+
+```bash
+# Look for cleanup task logs
+grep "cleanup_old_public_data" celery.log
+grep "Starting cleanup of old public data" celery.log
+```
+
+Task statistics are logged after each run:
+- Number of transcripts deleted
+- Number of meetings deleted
+- Number of orphaned recordings deleted
+- Any errors encountered

+# Reflector Webhook Documentation
+
+## Overview
+
+Reflector supports webhook notifications to notify external systems when transcript processing is completed. Webhooks can be configured per room and are triggered automatically after a transcript is successfully processed.
+
+## Configuration
+
+Webhooks are configured at the room level with two fields:
+- `webhook_url`: The HTTPS endpoint to receive webhook notifications
+- `webhook_secret`: Optional secret key for HMAC signature verification (auto-generated if not provided)
+
+## Events
+
+### `transcript.completed`
+
+Triggered when a transcript has been fully processed, including transcription, diarization, summarization, and topic detection.
+
+### `test`
+
+A test event that can be triggered manually to verify webhook configuration.
+
+## Webhook Request Format
+
+### Headers
+
+All webhook requests include the following headers:
+
+| Header | Description | Example |
+|--------|-------------|---------|
+| `Content-Type` | Always `application/json` | `application/json` |
+| `User-Agent` | Identifies Reflector as the source | `Reflector-Webhook/1.0` |
+| `X-Webhook-Event` | The event type | `transcript.completed` or `test` |
+| `X-Webhook-Retry` | Current retry attempt number | `0`, `1`, `2`... |
+| `X-Webhook-Signature` | HMAC signature (if secret configured) | `t=1735306800,v1=abc123...` |
+
+### Signature Verification
+
+If a webhook secret is configured, Reflector includes an HMAC-SHA256 signature in the `X-Webhook-Signature` header to verify the webhook authenticity.
+
+The signature format is: `t={timestamp},v1={signature}`
+
+To verify the signature:
+1. Extract the timestamp and signature from the header
+2. Create the signed payload: `{timestamp}.{request_body}`
+3. Compute HMAC-SHA256 of the signed payload using your webhook secret
+4. Compare the computed signature with the received signature
+
+Example verification (Python):
+```python
+import hmac
+import hashlib
+
+def verify_webhook_signature(payload: bytes, signature_header: str, secret: str) -> bool:
+    # Parse header: "t=1735306800,v1=abc123..."
+    parts = dict(part.split("=") for part in signature_header.split(","))
+    timestamp = parts["t"]
+    received_signature = parts["v1"]
+
+    # Create signed payload
+    signed_payload = f"{timestamp}.{payload.decode('utf-8')}"
+
+    # Compute expected signature
+    expected_signature = hmac.new(
+        secret.encode("utf-8"),
+        signed_payload.encode("utf-8"),
+        hashlib.sha256
+    ).hexdigest()
+
+    # Compare signatures
+    return hmac.compare_digest(expected_signature, received_signature)
+```
+
+## Event Payloads
+
+### `transcript.completed` Event
+
+This event includes a convenient URL for accessing the transcript:
+- `frontend_url`: Direct link to view the transcript in the web interface
+
+```json

+  "room": {
+    "id": "room-789",
+    "name": "Product Team Room"
+  }
+}
+```
+
+## Retry Policy
+
+Webhooks are delivered with automatic retry logic to handle transient failures. When a webhook delivery fails due to server errors or network issues, Reflector will automatically retry the delivery multiple times over an extended period.
+
+### Retry Mechanism
+
+Reflector implements an exponential backoff strategy for webhook retries:
+
+- **Initial retry delay**: 60 seconds after the first failure
+- **Exponential backoff**: Each subsequent retry waits approximately twice as long as the previous one
+- **Maximum retry interval**: 1 hour (backoff is capped at this duration)
+- **Maximum retry attempts**: 30 attempts total
+- **Total retry duration**: Retries continue for approximately 24 hours
+
+### How Retries Work
+
+When a webhook fails, Reflector will:
+1. Wait 60 seconds, then retry (attempt #1)
+2. If it fails again, wait ~2 minutes, then retry (attempt #2)
+3. Continue doubling the wait time up to a maximum of 1 hour between attempts
+4. Keep retrying at 1-hour intervals until successful or 30 attempts are exhausted
+
+The `X-Webhook-Retry` header indicates the current retry attempt number (0 for the initial attempt, 1 for first retry, etc.), allowing your endpoint to track retry attempts.
+
+### Retry Behavior by HTTP Status Code
+
+| Status Code | Behavior |
+|-------------|----------|
+| 2xx (Success) | No retry, webhook marked as delivered |
+| 4xx (Client Error) | No retry, request is considered permanently failed |
+| 5xx (Server Error) | Automatic retry with exponential backoff |
+| Network/Timeout Error | Automatic retry with exponential backoff |
+
+**Important Notes:**
+- Webhooks timeout after 30 seconds. If your endpoint takes longer to respond, it will be considered a timeout error and retried.
+- During the retry period (~24 hours), you may receive the same webhook multiple times if your endpoint experiences intermittent failures.
+- There is no mechanism to manually retry failed webhooks after the retry period expires.
+
+## Testing Webhooks
+
+You can test your webhook configuration before processing transcripts:
+
+```http
+POST /v1/rooms/{room_id}/webhook/test
+```
+
+Response:
+```json
+{
+  "success": true,
+  "status_code": 200,
+  "message": "Webhook test successful",
+  "response_preview": "OK"
+}
+```
+
+Or in case of failure:
+```json
+{
+  "success": false,
+  "error": "Webhook request timed out (10 seconds)"
+}
+```
