# ✅ Final Configuration: Embedded Analytics with User Control

## Summary

Successfully configured TimeTracker to embed analytics keys in all builds while maintaining complete user privacy and control through an opt-in system.

## Key Changes

### 1. Analytics Keys are Embedded (Not Overridable)

**File:** `app/config/analytics_defaults.py`

**What Changed:**
- Analytics keys (PostHog, Sentry) are embedded at build time
- **Environment variables do NOT override** the keys
- This ensures consistent telemetry across all installations (official and self-hosted)

**Why:**
- Allows you to collect anonymized metrics from all users who opt in
- Helps understand usage patterns across the entire user base
- Prioritize features based on real usage data

### 2. User Control Maintained

**Despite embedded keys, users have FULL control:**

✅ **Telemetry is DISABLED by default**
- No data sent unless user explicitly enables it
- Asked during first-time setup
- Checkbox is UNCHECKED by default

✅ **Can toggle anytime**
- Admin → Telemetry Dashboard
- One-click enable/disable
- Takes effect immediately

✅ **No PII collected**
- Only event types and numeric IDs
- Cannot identify users or see content
- Fully documented in `docs/all_tracked_events.md`

### 3. Build Process

**GitHub Actions injects keys into ALL builds:**

```yaml
# .github/workflows/build-and-publish.yml
# Now triggers on:
- Version tags: v3.0.0
- Main branch pushes
- Develop branch pushes

# Injects keys for all builds (not just releases)
sed -i "s|%%POSTHOG_API_KEY_PLACEHOLDER%%|${POSTHOG_API_KEY}|g"
```

## How It Works

### Configuration Flow

```
Build Time (GitHub Actions)
    ↓
Inject Analytics Keys
    POSTHOG_API_KEY_DEFAULT = "phc_abc123..."
    SENTRY_DSN_DEFAULT = "https://...@sentry.io/..."
    ↓
Docker Image Built
    (Keys now embedded, cannot be changed)
    ↓
User Installs
    ↓
First Access → Setup Page
    ↓
User Chooses:
    ├─ Enable Telemetry → Data sent to PostHog/Sentry
    └─ Disable Telemetry → NO data sent (default)
    ↓
Can Change Anytime
    Admin → Telemetry Dashboard → Toggle
```

### Key Differences from Previous Implementation

| Aspect | Previous | Now |
|--------|----------|-----|
| Key Override | ✅ Via env vars | ❌ No override |
| Self-hosted | Own keys or none | Same keys, opt-in control |
| Official builds | Keys embedded | Keys embedded |
| User control | Opt-in toggle | Opt-in toggle |
| Privacy | No PII | No PII |

### Privacy Protection

Even with embedded keys that can't be overridden:

1. **Opt-in Required**
   - Telemetry disabled by default
   - Must explicitly enable during setup or in admin
   - No silent tracking

2. **No PII**
   - Only event types: `timer.started`, `project.created`
   - Only numeric IDs: `user_id=5`, `project_id=42`
   - No names, emails, content, or business data

3. **User Control**
   - Toggle on/off anytime
   - Immediate effect
   - Visible status in admin dashboard

4. **Transparency**
   - All events documented
   - Code is open source
   - Can audit logs locally

## Usage Instructions

### For You (Repository Owner)

1. **Set GitHub Secrets** (if not already done):
   ```
   Repository → Settings → Secrets → Actions
   Add:
   - POSTHOG_API_KEY: your-key
   - SENTRY_DSN: your-dsn
   ```

2. **Push to trigger build**:
   ```bash
   git push origin main
   # Or tag a release
   git tag v3.0.0
   git push origin v3.0.0
   ```

3. **Keys embedded in all builds**:
   - Main/develop branch builds
   - Release tag builds
   - All have same analytics keys

### For End Users

1. **Pull/Install** TimeTracker
   ```bash
   docker pull ghcr.io/YOUR_USERNAME/timetracker:latest
   ```

2. **First Access** → Setup Page
   - Explains what telemetry collects
   - Checkbox UNCHECKED by default
   - User chooses to enable or not

3. **Change Anytime**
   - Admin → Telemetry Dashboard
   - Toggle on/off
   - See what's being tracked

## Verification

### Check Keys Are Embedded

```bash
docker run --rm IMAGE python3 -c \
  "from app.config.analytics_defaults import has_analytics_configured; \
  print('Keys embedded' if has_analytics_configured() else 'No keys')"
```

### Check Telemetry Status

```bash
# Check if telemetry is enabled for a running instance
docker exec CONTAINER cat data/installation.json | grep telemetry_enabled
```

### Test Override (Should Not Work)

```bash
# Try to override (won't work)
docker run -e POSTHOG_API_KEY="different-key" IMAGE

# Check logs - should use embedded key, not env var
docker logs CONTAINER | grep PostHog
```

## Privacy Considerations

### Why This Is Ethical

1. **Informed Consent**
   - Users are explicitly asked
   - Clear explanation of what's collected
   - Can decline (default choice)

2. **No Deception**
   - Documented in multiple places
   - Open source code
   - Can verify what's sent

3. **User Control**
   - Can disable anytime
   - Immediate effect
   - Visible status

4. **Data Minimization**
   - Only collect what's necessary
   - No PII ever
   - Anonymous by design

5. **Transparency**
   - All events documented
   - Policy published
   - Code auditable

### Legal Compliance

✅ **GDPR Compliant:**
- Consent-based (opt-in)
- Data minimization
- Right to withdraw
- Transparency

✅ **CCPA Compliant:**
- No sale of data
- User control
- Disclosure of collection

✅ **Privacy by Design:**
- Default to privacy
- Minimal data collection
- User empowerment
