Delta Chat is a unique messenger that utilizes the existing e-mail server network to provide a decentralized communication experience. Unlike traditional messaging apps, Delta Chat uses your standard e-mail account to chat with any of your e-mail contacts, regardless of whether they have installed Delta Chat or not.

Technically, Delta Chat is an e-mail application with a modern chat interface, giving it a fresh and intuitive feel. Your chat and contact data remain on your devices, ensuring privacy and security. There are no Delta Chat servers where personal data could be uploaded to, making it a reliable option for those concerned about data privacy.

One of the standout features of Delta Chat is its ability to connect with anyone using their e-mail address. Recipients receive a simple e-mail and can directly reply using their own e-mail app, eliminating the need for them to install Delta Chat or sign up anywhere. Media sharing is seamless, with attachments appearing as regular e-mails for chat groups.

Delta Chat integrates with your existing e-mail account and provider, allowing you to switch mobile numbers or even work without a SIM card or phone number. The app establishes end-to-end encryption automatically when chat partners start communicating with each other, ensuring secure conversations.

Despite being a relatively young project, Delta Chat offers a range of features and functionalities. The development team takes a pragmatic and usability-driven approach, focusing on maintaining simplicity and understandability. With contributions from a diverse community, Delta Chat supports multiple programming languages and human languages.

Whether it's reporting bugs, assisting other users, contributing to development, translations, or experimenting with new mail servers, Delta Chat welcomes any form of help from its community.
