Cybersecurity firm DarkMatter has launched its first smartphone, designed to stop spy agencies listening to you.

An Android device called Katim, it was made available commercially Monday at Mobile World Congress in Barcelona, Spain, and has a 5.2-inch display, as well as a high level of encryption.

DarkMatter unveiled the phone concept last year but has now brought it to market.

One security feature built by the Middle East-based firm is called "shield mode," which disconnects power from the microphone and camera on the device so that nobody can spy on your conversations.

"If you are to enter a secure meeting or a very confidential meeting as a business, you are striking a secret deal, or as a government having a secret meeting in that regard... you always tend to find people leaving their phone outside the meeting," Faisal Al Bannai, CEO of DarkMatter, told CNBC in an interview Tuesday.

"It's because you can't trust that no one, no super agencies are able to turn on that mic while you are sitting in the room."
