Sightline

SIGHTLINE — SPOT THE UNSEEN. Smart glasses with built-in cameras are nearly impossible to tell apart from ordinary eyewear. They can record video and photos without any visible indicator. As devices like Meta Ray-Ban, Snap Spectacles, and XREAL become mainstream consumer products, Sightline gives you awareness of who may be nearby. HOW IT WORKS Every Bluetooth-enabled camera glasses device broadcasts a wireless signal for pairing and connectivity. Sightline scans for these signals and identifies known camera glasses using a continuously updated signature database — all processed on your device, all private. A single detection may mean nothing. A device appearing near you across multiple days and different locations is a pattern worth knowing about. Sightline tracks and surfaces these repeat encounter patterns so you can make informed decisions.

Detection history, device labels, and preferences are stored locally and never uploaded. No account required. No location data leaves your phone. Delete everything at any time from Settings. IMPORTANT LIMITATIONS Sightline can only detect camera glasses that are actively broadcasting a Bluetooth signal. Detection indicates the possible presence of a compatible device — it does not confirm the device is recording, does not identify the device's owner, and does not prove any intent. Detection accuracy varies by device model, firmware, environment, and Bluetooth range. Sightline is a tool for personal awareness, not a guarantee of privacy.
