Threema is an encrypted instant messaging application for iOS and Android.[5][6] It can be used to send and receive asymmetrically end-to-end encrypted instant messages,[5][6][7][8] multimedia files and voice messages.[9]

Upon launching the application for the first time, it generates a key pair [10] and sends the public key to the server while keeping the private key on the user's device.[11] The application then encrypts all messages and media files that are sent to other Threema users with their respective public key.[7]

Threema is developed by the Swiss company Threema GmbH.[12] [13] The application is especially popular in German speaking countries,[14] where it has generated 2.8 million downloads to date.[15]
