Typical scan time

QR codes can be malicious

QR codes shouldn't be accessed blind

Whether it's a menu, a payment code, or a parking ticket machine, scanning a QR code without knowing anything about the destination first can leave your smartphone vulnerable.

Credential harvesting

Convincing fake login pages designed to capture usernames, passwords, and recovery details.

Destination obfuscation

Redirect chains that mask the final destination until after you have already committed to the visit.

Unsolicited downloads

Destinations that attempt to trigger downloads or app prompts before the user understands the context.

Quishing campaigns

QR-driven phishing attacks that bypass security tools which only inspect plain-text links.

Five layers of intelligence

Every scan runs through multiple independent signals giving you more protection than any other app on the market.

Local URL heuristics

Immediate structural analysis of the scanned link without waiting for network requests.

Google Web Risk

Cross-checking with established threat intelligence for known risk signals.

Domain age checks

Highlighting recently created domains, a common pattern in short-lived scam infrastructure.

Visual preview

A screenshot-style preview so the destination page can be inspected safely before it is opened.

AI-assisted analysis

Contextual reasoning to identify suspicious patterns that rules-based systems may miss.
