Why a Faraday sleeve

Airplane mode and powering off leave gaps.

Airplane mode is a setting you have to check. Powering off silences your alarm. UnTrack Sleeve closes the gaps both leave, and you can test it yourself in 10 seconds.

Settings leave gaps. UnTrack closes them.

01

Airplane mode leaves GPS on

GPS can keep logging your location in airplane mode. And if you’ve turned Wi-Fi or Bluetooth back on before, many phones keep them on next time.

GPS can keep logging your location.

02

Powered off isn’t fully silent

With Find My enabled, iPhone 11+ and Pixel 8+ can keep a low-power Bluetooth beacon running for hours after shutdown. Powering off also silences your alarm.

Find My can keep a Bluetooth beacon running for hours, and your alarm stops.

03

A seal you can test

Put your phone inside, close it fully and call it from another phone. It goes straight to voicemail.

Seal it, call it. Straight to voicemail.

Built in layers

Everything that makes the seal

Roll-top seal

Fold the top twice to close the opening. A sleeve that isn't fully closed can leak signal.

Toggle & cord lock

The elastic cord hooks over the toggle so the fold can't loosen in a pocket or bag.

Product cutout
on dark background
Multi-layer shielding

A layered nickel-copper fabric lining blocks radio signals when the sleeve is fully closed.

Woven outer shell

A woven exterior that looks like an everyday pouch, not a gadget.

How it works

Offline in three seconds

Test it yourself: close it fully and call your phone from another one. It goes straight to voicemail.

Step 1 · slide phone in
01

Slide it in

Drop your phone in screen-first. It fits with a slim case on.

Step 2 · roll the top
02

Roll the top twice

Two folds close the opening fully. This is what makes the seal.

Step 3 · hook the cord
03

Lock it

Loop the cord over the toggle. You are offline until you open it.

Lifestyle · sleeve in jeans pocket

Pocket-sized privacy

Slim enough for a jeans pocket, a jacket or a work bag. Nobody knows it's there.

Bedside · lights out

Phone off the network. Alarm still on.

Seal it on the nightstand. Screen and notifications out of sight.

Travel · airport, hotel, café

Nothing connects in public

Airports, hotels, cafés. No Wi-Fi, Bluetooth or NFC connections while it's sealed.

Powering off stops cellular and Wi-Fi, but it also silences your alarm and takes time to restart. Many newer phones (iPhone 11+, Pixel 8+) keep a low-power Bluetooth "Find My" beacon running for hours after shutdown, and Express Transit cards can stay active. UnTrack Sleeve keeps the phone on, so your alarm works, while blocking every signal in and out.
