Description

Delta Chat is a reliable decentralized instant messenger that is easy and fun to use for friends, family, groups and organizations. Delta Chat is developed by a dedicated FOSS contributor community that jointly releases refinements and new features several times a year, across many stores and platforms world-wide.

Features at a glance:

• Private. Instant on-boarding without a phone number or other private data.

• Friends & Family: Only chat with people you know. Unknown users cannot message or follow you without mutual consent.

• Flexible. Supports multiple chat profiles and is easy to setup on multiple devices.

• Extensible. Add tools like shopping lists, calendars or gaming apps to any chat.

• Reliable. Works under bad and adversarial network conditions.

• Secure. Audited End-to-End encryption safe against network and server attacks.

• Sovereign. Can be run with your own e-mail address or server.

• FOSS. Fully Open Source/Free Software, built on Internet Standards.
