Halo: Hidden Camera Sweep
Hotel & Airbnb privacy check

iPhone
Travel with peace of mind. Halo sweeps your room for hidden cameras using three signals, 100% on your device. No location, no account, no surprise charges.
Check a hotel room or holiday rental with a guided checklist and three supporting tools.
Halo helps you observe signals that deserve a physical check. It cannot identify a camera on its own or guarantee that a room is free of cameras.
THREE COMPLEMENTARY METHODS
• Magnetic field: compares readings with a baseline calibrated in the room. Metal, speakers and everyday electronics can also cause anomalies.
• Camera: highlights bright spots and possible reflections. Infrared sensitivity depends on your phone, and a bright spot does not prove there is a lens.
• Local network: looks for devices with selected open ports on your Wi-Fi. An open port does not confirm a camera; disconnected or isolated cameras may not appear.
CHECK STEP BY STEP
Follow the guided sweep and keep its progress on this device. Read the summary and export a PDF of the observations. The report records signals; it does not certify safety or prove a camera is present.
ACCESS WITHOUT A SUBSCRIPTION
Three scans without signals are included. Scans with signals do not use this allowance, and neither do checks that Halo itself could not complete.
• Trip pass: premium access for 7 days on this device. No renewal. Lost after reinstalling and cannot be restored.
• Forever: permanent unlock, restorable with your store account.
Prices and currency are shown in the app before purchase.
PRIVACY
Camera frames, readings and results are processed on your device and excluded from diagnostics. No account or location permission. Usage and crash diagnostics are optional: off until you enable them in Settings, where you can disable both together.
LIMITS
A scan without signals does not guarantee the absence of cameras. A phone may miss cameras that are off, isolated from the network or recording to a memory card. Combine Halo with a careful physical inspection and professional assistance when needed.
