Protox

Protox is a Tox (https://tox.chat/) client written in QML/C++ (Qt 5). This client is an alternative to: Antox, Trifa, uTox.

- Everything you do with Tox is encrypted using open-source libraries. The only people who can see your conversations are the people you're talking with.

- Tox has no central servers that can be raided, shut down, or forced to turn over data — the network is made up of its users. Say goodbye to server outages!

- Tox is free software. That's free as in freedom, as well as in price. This means Tox is yours — to use, modify, and share — because Tox is developed by and for the users.

All Tox features are implemented, except for:

- Conferences

- Audio/video calls

To prevent Android from disconnecting application from network in the background mode, under battery settings choose the “Don't Optimise” option for Protox.
