X-ray vision for privacy policies - Instant risk scores for the terms you'll never read

Privacy Forensics transforms impenetrable legal documents into clear, actionable privacy risk scores. Stop blindly clicking "I Agree" - know the risks first.

• Four Risk Categories: Data Resale, Biometric Collection, Indefinite Retention, Vague Language
• AI-Enhanced Validation: GPT-4o validates findings against GDPR regulations
• Specific Citations: Get exact GDPR article references (e.g., "Article 5(1)(b) - Purpose Limitation")
• Visual Dashboard: Color-coded risk scores (0-100) with interactive charts
• Clause-Level Breakdown: See exactly which sentences triggered each flag

• Auto-Detection: Recognizes privacy policy pages automatically
• Instant Risk Badges: See privacy scores without leaving the page
• Permission Alerts: Flags camera, microphone, location, and biometric data requests
• One-Click Analysis: Send policies to web app for detailed forensics

• Python 3.11+
• Node.js 18+
• Backboard.io API key (Get one here)

## 🎮 Usage Examples

### Web Application

1. **Paste a privacy policy** into the text area
2. **(Optional)** Enable AI Enhancement for GDPR validation
3. **Click "Analyze Policy"**
4. **View results**: Overall score + category breakdown + flagged clauses

### API Endpoint
```bash
curl -X POST http://localhost:5000/analyze \
  -H "Content-Type: application/json" \
  -d '{
    "policy": "Your privacy policy text here...",
    "use_ai": true
  }'

Response:

{
  "overall": {"score": 65.3, "risk_level": "high"},
  "data_resale": {
    "score": 100,
    "matches": [
      {
        "text": "We share data with advertisers...",
        "matched_keyword": "advertisers",
        "ai_validation": "YES - conflicts with GDPR Article 6(1)(a)..."
      }
    ]
  }
}

from risk_analyzer import RiskAnalyzer
analyzer = RiskAnalyzer()
with open('test_policies/whatsapp.txt') as f:
    result = analyzer.analyze(f.read())
    print(f\"Risk Score: {result['overall']['score']}\")
"
