About this app

Stop scanning QR codes blindly. LinkGuard is a QR code scanner and link checker that checks every QR code and link before you open it — helping detect scams, phishing sites, malware, and suspicious links in seconds.

WHY LINKGUARD?

Malicious QR codes are showing up everywhere — parking meters, restaurant menus, posters, fake package delivery texts, and phishing emails. A single tap can take you to a fake login page, malware download, or payment scam.

LinkGuard helps you check QR codes and links before opening them, giving you a clear safety verdict so you can browse with confidence.

KEY FEATURES

• Instant QR Code Scanner

Scan QR codes at restaurants, parking meters, posters, flyers, events, and more. Get a safety verdict before visiting the linked website.

• URL & Link Safety Checker

Paste any URL or link into LinkGuard, or share a link from WhatsApp, Messages, Email, or any other app to check it for potential threats.

• Real-Time Threat Database Checks

Links are checked against Google Safe Browsing, URLhaus, and OpenPhish threat databases to help identify known malicious and phishing URLs.

• Redirect & Shortened Link Detection

Scammers can hide dangerous websites behind URL shorteners and redirects. LinkGuard analyzes redirects to help reveal the final destination before you visit it.

• On-Device Phishing Detection

Even without an internet connection, LinkGuard can detect suspicious URL patterns including punycode domains, lookalike websites, brand typosquatting, suspicious top-level domains, raw IP addresses, and credentials hidden inside URLs.

• Clear Safety Verdicts

Every scan gives you an easy-to-understand result: Safe, Suspicious, or Dangerous. See the reasons behind the verdict so you can make an informed decision before opening a link.

• Scan History

Keep a record of previously scanned QR codes and links. Review your scan history anytime and quickly revisit previous safety results.
