If anyone knows a thing or two about avoiding prying eyes, it's John McAfee.

After managing to elude Belizean authorities in an epic real-life murder drama last year, the antivirus pioneer is now looking to help you keep your own communications under wraps. In partnership with Rochester, N.Y.-based startup Etransfr, McAfee's software development company Future Tense Systems on Friday unveiled a new secure messaging app, dubbed Chadder.

The free app uses so-called key server encryption technology to ensure that nobody can read your messages except for the intended recipient. In a statement, McAfee called Chadder an "unprecedented messaging platform."

"We have developed this highly secure system with an extraordinary team of developers at the prestigious RIT (Rochester Institute of Technology)," the 68 year-old entrepreneur said. "Chadder is a fun and easy-to-use messaging app that happens to keep your communications private. So private that we can't see it ourselves."

Here's how it works: When you send a message using the app, all Chadder can see is the encrypted text. No one has the key to unlock your message except the person receiving the text.

Etransfr founder Lexi Sprague said the app strikes a balance between usability and privacy. "Chadder is here to prove that young people want privacy just as much as adults do," Sprague said. "At the end of the day it is about giving privacy and control back to the user without scaring them off with complicated log in and messaging processes."

The app comes after McAfee spent a good part of late 2012 and 2013 on the run after being named a suspect in the shooting of his 52-year-old American expatriate neighbor in Belize. Since then, he has been caught up in a bizarre tale of viruses, women, and extortion, all of which may eventually make its way to the big screen, with the help of Warner Bros. Studio.

McAfee also last year unveiled a small router aimed at blocking NSA surveillance.

Chadder is currently available for download on Google Play and the Windows Phone store and should be hitting iOS "in the following weeks."
