In 2014, Felix Leupold and Stefan George, two master students from the Hasso Plattner Institute, founded SafeChat.IM—an encrypted instant messenger. SafeChat.IM offers encryption to everyone with a simple-to-use app that automates message encryption and integrates it into the user’s social network seamlessly. SafeChat.IM is available on iPhone & web browsers. Chat with your friends encrypted on mobile and desktop devices!
