GlassGuard: Glasses Detector

Corelabsapp

About this app

Camera glasses can look like ordinary eyewear. GlassGuard checks supported Bluetooth Low Energy signals, alerts you to a possible match, and explains the clues behind it. Core detection is free, private, and works offline.

CORE DETECTION IS FREE

There is no blurred result or paywall before a warning. Scan nearby signals, inspect matches, and understand the result without paying.

UNDERSTAND EVERY MATCH

GlassGuard explains which signals influenced its confidence, including manufacturer identifiers, service UUIDs, model-name patterns, signal behavior, and built-in and manually added signatures. No single signal is presented as proof.

STAY IN CONTROL

• Review recent encounters stored on your phone
• Compare two scans to see what appeared or disappeared
• Temporarily mute a matching radio profile for one hour
• Add a missing signature manually
• Add private place labels and notes
• Choose quiet or urgent alerts

IMPORTANT LIMITS

Bluetooth cannot prove that someone is recording. Devices that are off, use an unknown signature, or do not broadcast Bluetooth may remain invisible. Treat an alert as a reason to calmly check your surroundings, not as proof or a reason to confront anyone.

GlassGuard does not request location access on modern Android. Detection history stays on your phone. Manually added signatures stay on your phone.

GlassGuard is independent and is not affiliated with Meta, Ray-Ban, Oakley, Snap, or Vuzix.
