-- **IP anonymization** option for GDPR compliance
-- **User agent sanitization** removes sensitive information
-- **No personal data** stored in violation reports
+**⚠️ Data Collection Notice:**
+- **IP addresses** are collected and stored in memory for security monitoring
+- **User agent strings** are stored for browser compatibility analysis
+- **Legal basis**: Legitimate interest for security incident detection and prevention
+- **Retention**: In-memory storage only, automatically purged after 7 days or application restart
+- **Data minimization**: Only violation-related metadata is retained, not page content
