Our phones leave behind digital footprints, even when we're not actively using them. The NSA can pull up your call history  anytime, and some department stores are tracking customers through their phones' WiFi  signals. People have a right to control their privacy, which is why a New York-based designer and engineer created Off Pocket  ($80). It's a flexible phone pouch that takes devices off the grid by blocking WiFi, GPS, and cellular signals.
You could turn off your phone, but many mobile devices (like the iPhone) have batteries that cannot be removed, and therefore they can still transmit wireless signals. A phone that has already been hacked can send data even in Airplane Mode or when it's powered down.
The Off Pocket is a physical failsafe barrier that will make your phone invisible to wireless networks. It'll even shield your body from radiation emitted by devices.
The accessory is sold exclusively through Privacy Gift Shop (which accepts Bitcoin!) and comes in three sizes. This nifty size finder  will match you with the right model. Would you get your phone its own privacy pouch?
