Monal - XMPP chat

Monal allows you to connect to your chat server without having to give a third party access to your password or messages. Whether it is a personal Google talk account or a corporate chat server, it is important not to give someone access to sensitive information. This app has no ads, no user behavior tracking and all messages are exchanged directly with the XMPP chat server.

Notable features:
- Open Source
- No Ads! Strong focus on privacy. Does not phone home and does not have "metrics" software beyond anonymous crash reporting (crashlytics). Does not read any personal information.
- A direct client that does not transmit your password to a 3rd party.
- Reply from OS notification bubbles
- Will work with corporate XMPP servers that require VPN
- MUC multi user chat
- OMEMO encrypted chat
