QRDefender: Secure QR Scanner

About this app

QRDefender scans and analyses QR codes before you interact with them, protecting you from QRishing — phishing attacks hidden inside QR codes.

SCAN FIRST, ACT SAFELY
Every QR code is analysed and classified into clear safety levels: Safe, Privacy Warning, Suspicious, or Dangerous. You see exactly what a QR code contains — the URL, phone number, payment details,
or WiFi network — before you open, call, or connect.

ADVANCED THREAT DETECTION
• Phishing pattern recognition and brand impersonation detection
• Typosquatting analysis for lookalike domains
• SSL/TLS certificate verification
• Redirect chain tracking — see where a link really goes
• URL shortener unmasking
• Suspicious TLD and port detection
• Tracker identification

PRIVACY FIRST
• Biometric or device password lock
• No personal data, URLs, or scan content shared
• Analytics and crash reporting disabled by default
• Data stored securely on your device
