Delta Chat is a decentralized and encrypted messaging app, available for mobile and desktop platforms.

Delta Chat looks like WhatsApp, Telegram and other messaging apps but internally it is an encrypted e-mail client. Users can signup anonymously to a variety of interoperable chatmail servers[4] which are minimal e-mail servers optimized for fast and secure operations. It is also possible to use classic e-mail servers and an existing e-mail account in which case Delta Chat acts as a normal e-mail app.

Delta Chat supports direct(one-on-one) chats as well as group chats. End-to-end encryption[5] with contacts and group chats is automatically established via Autocrypt which in turn uses a subset of the OpenPGP standard.

Delta Chat also supports Webxdc[6] (in-chat mini-apps) allowing users to play mini-games or use collaborative tools with their chat partners.

Reception

edit

The popular German media conglomerate Heise published two articles about Delta Chat, the first in 2019[7] and the second in 2023[8]

In 2019 the regional newspaper HNA published an article about Delta Chat.[9]

As of 2024, the Delta Chat project underwent four independent security audits and one independent security analysis.[10]
