Delta Chat Android is the official Android client for Delta Chat, a decentralized private messenger that runs over email infrastructure using the Chatmail core library. It provides encrypted chat, chat-shared tools and games, and is available via Google Play and F-Droid.

Use cases

• private messaging without sharing phone numbers
• chat over existing email accounts
• end-to-end encrypted group chats
• decentralized alternative to WhatsApp or Signal
• messenger that works without a central server

When to choose

• you want a privacy-focused messenger that uses email servers as transport
• you need an Android client for Delta Chat or Chatmail
• you prefer decentralized, federated messaging with e2e encryption

When to avoid

• you need real-time low-latency messaging with push notifications typical of centralized messengers
• your contacts all use mainstream messengers and interoperability with email is not desired
• you need an iOS or desktop client rather than Android
