LucidQR: See Before You Scan
QR codes are convenient—but they can also be dangerous. LucidQR analyzes QR codes on your device to help you spot phishing, malware, and suspicious links before you click.
The QR Code Problem
QR codes are everywhere—restaurant menus, payment terminals, event check-ins, product labels. But unlike a visible URL, you can't tell where a QR code leads until you've already scanned it.
- Phishing attacks: Fake payment pages and credential harvesting
- Malicious redirects: Links to malware downloads or exploit kits
- Social engineering: Urgency tactics ("Scan now or your account expires!")
- Physical tampering: Stickers placed over legitimate QR codes
How LucidQR Protects You
On-Device Analysis
All scanning and analysis happens locally on your device. No cloud uploads, no third-party tracking, no data collection.
Instant Risk Assessment
LucidQR evaluates URLs for known phishing patterns, suspicious domain names, excessive redirects, and other red flags—before you visit them.
Explainable Results
We don't just say "risky"—we show you why. See the actual URL, domain age, redirect chain, and specific warning signals.
Privacy-Preserving
Zero telemetry. Your scan history never leaves your device. We don't know what you scan, where you are, or who you are.
Cross-Platform
Available for iOS, Android, and desktop. Same privacy-first approach across all platforms.
Regular Updates
Pattern recognition models are updated regularly to catch new threat types. Updates are delivered securely and transparently.

Frequently Asked Questions
Is LucidQR really private?
Yes. All QR code analysis happens on your device. We don't upload scanned codes, URLs, or any telemetry. Your scan history stays on your device and is never transmitted to GuardGraph or anyone else.
How does it detect risky QR codes?
LucidQR uses pattern recognition to identify suspicious URLs, including known phishing domains, excessive redirects, typosquatting, unusual port numbers, and other common threat indicators. The analysis models run entirely on-device.
Does it work offline?
Yes. The core scanning and risk assessment work without an internet connection. Optional threat intelligence updates require connectivity but are always optional.
Is it free?
LucidQR will have a free tier with core scanning features. Enterprise features (API access, centralized management, on-premise deployment) will be available via paid plans.
Can I use it for my business?
Yes! For business deployments, contact us to discuss your requirements. Enterprise features are on our roadmap.
How can I report a security issue?
Please email security@guardgraph.com. We respond to all security reports within 24 hours. See our Contact page for details.
