01
Install the app
Install Nearby Glasses Alert on Android and allow Bluetooth + notification permissions.
How it works
A short setup flow designed for speed and clarity. Nearby Glasses Alert continuously scans Bluetooth Low Energy signals, scores matches, and pushes alerts only when risk is meaningful.
02
Tap Start Scan
One tap starts scanning. No account, no onboarding maze, no extra hardware.
03
Get alerted nearby
When supported smart glasses are detected, alerts arrive even if the app is closed.
What it detects
Coverage includes major smart-glasses brands and evolves through over-the-air rules updates. As new 2026 models appear, rules can be refreshed without requiring a full app update.
- Meta Ray-Ban
- Snap Spectacles
- Vuzix
- XREAL
- Rokid
- and more
Rules update automatically, keeping detection current for new 2026 models.
Privacy promise
Built with strict privacy defaults and minimal data handling. Nearby Glasses Alert is designed to detect nearby devices, not track people.
P1
No personal data collection
No account and no personal profile. The app does not collect identifying personal data.
P2
On-device processing
BLE detection logic runs on your phone. Scanning does not require cloud processing.
P3
Hashed identifiers
MAC identifiers are hashed. Raw identifiers are not stored or sent.
P4
No analytics or ads
No analytics SDKs and no ad SDKs. Internet is used only for rules updates.
FAQ
Answers to the most common setup, privacy, and detection questions.
Does this drain my battery?
The app uses efficient BLE scanning and responsible background modes. Battery use varies by device and scan time.
Does it need internet?
Scanning works offline. Internet is only needed occasionally for rules updates.
Will it detect every pair of glasses?
No detection system is perfect. The app covers supported models and improves continuously with updates.
Is my data safe?
Yes. No personal data collection, hashed identifiers, and no third-party sharing.
Does it keep scanning if I close the app?
Yes. When enabled, scanning can continue in the background and notifications can still be delivered if supported devices are detected.
What happens after I reboot my phone?
If scanning was active, the app can resume behavior after reboot on supported Android versions so protection is restored quickly.
How does it reduce false positives?
It uses confidence scoring from multiple BLE signals, sensitivity levels, and cooldown logic to reduce noisy repeated alerts.
Why might some Meta alerts be uncertain?
Some Meta Bluetooth identifiers are shared across product families. The app combines additional signals when available to improve confidence.
Which devices are intentionally not targeted?
Audio-only smart eyewear without cameras is not the primary target. The app focuses on camera-capable smart glasses risk scenarios.
Do I need to create an account or sign in?
No. There is no account system. Install, grant permissions, and start scanning.
Is internet required all the time?
No. Live scanning works offline. Internet is only used occasionally for detection rules updates.
