Tchapper represents a new mobile messaging app, which enables intelligent privacy filters. Today the company has announced the launch of a new kind of privacy feature that allows intimate messages to be delivered simply by shaking your iPhone or Android device. Messages can be deleted by both sender and receiver, or stored in a private messaging cloud. The Tchapper app can also send “flash messages” that disappear after 20 seconds. Tchapper also has privacy features on iMessage, and plans to deliver privacy features on additional messaging platforms, including WhatsApp, Facebook Messenger, and Skype.

Tchapper’s patent-pending technology enables users to encode their messages by shaking their device, so that no one else can see their messages or notifications. Shaking the device, or using the fingerprint sensor, to read direct messages or private messages within a group, can decode messages. Tchapper is currently available in English and French in beta version, with more than 150,000 users, and will soon be available in more than 10 languages.

Developed by Daniele Amsellem, the Tchapper app delivers a new kind of privacy channel for mobile users without restricting them to a single privacy app. Now, all conversations on mobile messaging can be made private with Tchapper, providing greater levels of communication control. The Tchapper interface also creates a new paradigm for messaging, with circles representing communication.

“Our idea was to clearly get privacy right, on the mobile device, and not only on your server, for the first time. Tchapper enables coded messages to be created and stored on your device only, using a filter,” said Daniele Amsellem, founder of Tchapper, and one of a growing number of French female entrepreneurs. “While Facebook Messenger, Kik, or WhatsApp are considering security to compete against Telegram, they completely miss the social privacy needs which begins around us: in the bus, at home, at the office. We have gamified mobile privacy with Tchapper, enabling users to taking control of their interface. Thus, no need to turn your phone around during a meeting, a dinner, or a party. We think that more people will want to ‘shake’ their messages to make them private.”
