Three privacy modes. One pocket-size device.
They listen
for signal.
Give them noise.
Your phone, watch, earbuds and car chatter wirelessly all day. Nearby scanners can sit back and take notes. Flock Block detects them and can alert you when one may be collecting consumer data. Then it floods the air with extra broadcasts, so what they collect stops being worth much.
The problem
Nobody is
hacking you.
They just listen.
Passive scanning is the quietest form of observation there is. Nothing gets broken into. Something simply sits there, writes down what floats past, and lets time turn it into a profile.
- 01
It never stops
Bluetooth and Wi-Fi devices announce themselves constantly, even sitting in your pocket doing nothing.
- 02
Anyone can listen
Receiving those announcements takes no permission, no hacking and about thirty dollars of hardware.
- 03
Patterns are the prize
One reading is trivia. The same handful of devices seen at the same places daily is a pattern.
- 04
You are the constant
You don't have to be named to be recognised. The bundle of things you carry is enough.
Three steps.
No settings.

- 01
Scanners listen
A receiver somewhere nearby is quietly logging every wireless announcement in range. Yours included.
- 02
Flock Block talks over it
Switched on, it broadcasts a continuous crowd of extra Bluetooth and Wi-Fi activity around you.
- 03
Clean data turns to soup
Instead of a tidy handful of devices, the log fills with company. Sorting the real from the rest gets expensive.

Three privacy modes
One small device.
Three focused modes.
Choose one mode at a time. Each gives Flock Block one clear job, with a simple light to show what it is doing. Hold the button for two seconds to switch.
Privacy Mode
Adds decoy Bluetooth and Wi-Fi activity and watches for signs of active wireless scanning nearby.
Tracker Detection
Watches for supported separated location trackers—including AirTag and compatible Find My and Find Hub devices—that remain nearby, then alerts you.
VPN Router
Creates private Wi-Fi for up to three devices and sends traffic through your WireGuard-compatible VPN service. If protection drops, internet traffic pauses.
The device
Flock
Block
One matte block, small enough to lose in a jacket pocket. The name describes its compact block shape—not signal blocking. One button and a single light keep the interface simple.
