The OFF Pocket concept was first developed in 2011 as a reponse to the lack of control over mobile phone tracking.


Commonly asked questions about the OFF Pocket
  • How does it work?
    • The OFF Pocket is a shield between your phone and radio signals. The metal-plated fabrics reflect radio signals. The concept is similar to a faraday cage in that the inside of the case has zero signals. However, the OFF Pocket is slightly different because it's a reflective shield.
  • What is the difference between the OFF Pocket and airplane mode?
    • Airplane mode works great in certain situations, but is software and hardware dependent. The OFF Pocket is software and hardware agnostic, meaning it does not matter which OS or phone you use, the OFF Pocket is compatible with all mobile phones so long as they properly fit inside. If you change carriers or switch phones, the OFF Pocket works equally well.
  • Why not turn off my phone?
    • Turning off and on a smartphone can take over 40 seconds. It's inconvenient. As a result many people never turn off their smart phone, allowing it to transmit bits of data all throughout the day and night. As phone hardware and operating systems become more advanced, it's likely that the electronics inside never fully turn off, giving an opportunity for programs like Carrier IQ to continue logging data and tracking user locations.
  • Will it damage my phone or affect my service?
    • No. The OFF Pocket does no damage to a phone. Service is resumed when the phone is taken out of the case, just as it does when entering or exiting areas where there is no reception.
  • Does it affect battery life?
    • Some phones will see an improvement in battery life since the phone is not transmitting data, while others may see a decrease in battery life because the phone continuously searches for signals. Performance is dependent on your phone's operating system. Initial tests with an iPhone have shown an improvement in battery performance. More tests will be published.
  • How much will it cost?
  • What about removing the battery?
    • Not all phones have a removable battery.
  • What about putting your phone in the fridge?
    • This technique was used by Edward Snowden.It can offer limited shielding from phone signals and audio. The OFF Pocket provides more RF shielding and is recommended for blocking electronic eavesdropping.

The Story

The OFF Pocket began as experiment in 2011. I wanted more control over my phone and more privacy. The first OFF Pocket was designed as a back-pocket in a pair of pants. I wore the pants often and they worked. But, I needed a way to make it more accessible. So I just made a standalone pocket, and called it the OFF Pocket.

In 2011 and 2012 I worked with friends to sew several prototypes and by the end of 2012 had several functioning phone case prototype. I began to give offer them to friends for user testing and to learn how they held up to wear and tear. Over the course of 2012 I had about a half-dozen OFF Pockets floating around NYC.

Towards the end of 2012 I teamed up with fashion designer Johanna Bloomfield to develop a new prototype for the Stealth Wear exhibition in London in 2013. Together we iterated through dozens of new designs and came out with the first version of the OFF Pocket in January of 2013. It was well received and the limited supply of a dozen sold out quickly. We both decided that this project would be a great fit for Kickstarter.

During the next 6 months, we developed the first commercially available version of the OFF Pocket and, together we launched the product in August, 2013.

Adam Harvey is a designer whose work in privacy and countersurveillance includes anti-drone fashion and camouflage from face detection. His projects have earned a Core77 design award, a Webby Nomination, a commission grant from, and received widespread press coverage including interviews with the BBC, The Guardian, Wired, Air Force Times, Reuters, Scientific American, VICE, and Dazed and Confused.



The first OFF Pocket was designed in collaboration with NYC-based fashion designer Johanna Bloomfield.
