ZuckOff is a smartphone app that scans Bluetooth Low Energy (BLE) broadcasts and flags signals matching its rules for camera-equipped glasses. A match can suggest compatible hardware is nearby, but it cannot tell whether the glasses are recording or who is wearing them.
How ZuckOff recognizes nearby glasses
Bluetooth Low Energy advertisements are short wireless broadcasts that nearby devices can send. ZuckOff compares them with detection rules based on device signatures and manufacturer identifiers. Its developer, Pawel Szydlowski, names Ray-Ban Meta, Oakley Meta and Snap Spectacles as detectable examples; the app may flag some similar hardware with lower confidence.
ZuckOff also logs Bluetooth devices generally, not just glasses. It displays the evidence behind each flag so users can assess what triggered it.
What a ZuckOff alert actually tells you
Signal strength offers a rough estimate of proximity, not a direction or precise location. A flag means a Bluetooth signal matched the app’s rules; it does not establish that a camera is recording or identify the person wearing the glasses.
Why no alert isn’t an all-clear
Some standalone glasses models may remain silent. So an empty scan does not establish that no smart glasses are nearby—or that nobody is recording.
What the iOS privacy policy says
ZuckOff’s iOS privacy policy, updated September 12, 2026, says ordinary Bluetooth scan observations are stored on the device. It says the app makes no network request unless a user chooses to compose and submit a hardware report. CSV exports are passed to the iOS share sheet at the user’s direction.
