Delta Chat v1.42.8

Delta Chat is a unique messenger that leverages the vast and decentralized communication network of existing e-mail servers. It allows users to seamlessly chat with their e-mail contacts using their standard e-mail account.

In technical terms, Delta Chat functions as an e-mail application but presents a modern chat interface. It ensures that all chat and contact data remain securely stored on users' devices, without any uploads or centralized control of personal information like address books or calendars. Delta Chat operates without relying on any servers of its own, making it a truly decentralized platform.

One of the standout features of Delta Chat is its universal compatibility. Users can communicate with anyone worldwide by simply using their e-mail addresses. Recipients receive messages as regular e-mails and can conveniently reply using their preferred e-mail app, without the need to install Delta Chat, visit websites, or sign up anywhere else. Moreover, when sharing media files within a chat group, recipients receive a user-friendly e-mail with attachments, ensuring a seamless multimedia chatting experience.

Delta Chat seamlessly integrates with different e-mail accounts and providers, giving users the freedom to switch mobile numbers or even operate without a SIM card or phone number. End-to-end encryption is automatically established whenever chat partners initiate communication, enhancing security and privacy.

Despite being a relatively young project, Delta Chat already offers a wide range of features and capabilities. Its development team follows a pragmatic and usability-driven approach to decentralized messaging, prioritizing functionality over unnecessary complexity. Continuous optimization and removal of unnecessary technologies ensure that Delta Chat remains maintainable and user-friendly. The project also benefits from contributions in various programming languages and translations into multiple human languages.

The Delta Chat team appreciates any form of assistance from the community, including bug reports, forum support, participation in open development through pull requests and reviews, translations into new languages, development of new bots, and experimentation with new mail servers.
