Delta Chat is a decentralized, end-to-end encrypted messenger that works over existing email infrastructure (IMAP/SMTP) instead of a proprietary server. Official clients are available for desktop, Android, and browser, with chat-shared tools and games, aimed at people who want private messaging without depending on a single centralized service.
