ArcaneChat

ArcaneChat is an Android messaging application built around encrypted conversations, presented by its publisher as an option for family and small-group chat. Messages are exchanged in encrypted form, and the interface follows the familiar pattern of chat lists and threaded conversations.

The stated emphasis is on responsiveness in everyday use and on a small circle of contacts rather than large public communities. As with any messenger, both correspondents need compatible software for encrypted exchange to work, so usefulness depends on who else in the group is willing to install it.

ArcaneChat is published by Asiel Díaz Benítez under the GPL-3.0-only license and is available for Android; there is no listed desktop client, so it is a phone-side application.
