About this app

Tchap is an instant messaging service intended for communications by French administration agents, to exchange information on the move or from an office workstation.

Tchap allows you to chat via messages in pairs and in groups, and to share files like any instant messenger, with an integrated directory of user agents, simultaneous use on several devices and confidentiality of private exchanges.

Agents can invite outsiders into a professional conversation.

The app requires the USE_FULL_SCREEN_INTENT permission to ensure that our users can effectively receive call notifications even when their devices are locked.

Bonjour ! Tchap est une application réservée aux agents publics. Pour vérifier que votre administration peut l'employer, RDV ici : https://tchap.beta.gouv.fr/#joinUs. Si vous souhaitez l'utiliser mais que votre administration n'est pas encore utilisatrice de Tchap, vous pouvez nous contacter à tchap@beta.gouv.fr ! Nivann de Tchap

Would never trust a government lauching an IM service. I know I can't use this, but it is open source, so if anyone else makes it, I will not use it
