About this app

QRSentry is a QR code security scanner that protects you from phishing links and malware URLs. Every QR code you scan is analyzed for threats before you open it — real phishing protection, not just a basic scanner.

■ Key Features

• 14 QR type recognition
Automatically identifies URL, Wi-Fi, Contact (vCard), Email, SMS, Phone, Location, Calendar Event, OTP, Crypto, Deep Link, Text, and more — the right action for every code.

• Real-time URL safety rating (SAFE / SUSPICIOUS / DANGEROUS / UNKNOWN)
Instant 4-level threat assessment on every scan. Dangerous links are flagged before you tap, blocking phishing attempts before they happen.

• PhishTank + URLhaus malware database
Backed by two of the world's largest threat intelligence feeds, updated daily. Known malicious URLs are blocked immediately.

• Dual analysis engine (server verification + local heuristics)
Firebase Functions server-side analysis combined with on-device heuristic checks. Basic protection even when offline.

• QR code generator
Create QR codes for URLs, plain text, Wi-Fi credentials, and contact cards directly in the app.

• Home screen Quick Scan widget
Launch a scan instantly from your home screen without opening the app.

• Weekly security report notifications
Receive a weekly summary of your scan activity, threats blocked, and safety statistics.

• Scan history + CSV export
All scan results are stored locally. Search your history and export to CSV anytime.

• Share scan results
Share any analysis result directly to other apps via the system share sheet.

• Fully offline capable
Scan history is stored in an on-device Room database — browse your history with no internet connection required.

QRSentry sends scanned URLs to its server for threat analysis using only the minimum data necessary to provide the service. No personally identifiable information is collected.
