Kontalk
Community-driven messaging

Follow @kontalknet on Twitter or identi.ca to keep up to date with the latest changes and on service status!

Kontalk is a secure instant messenger, allowing you to send and receive text, image and voice messages (other file types coming soon) to and from other Kontalk users completely free of charge (*).

  • Your phone number is your ID. No usernames or passwords
  • It automatically finds other Kontalk users by looking at your address book, making it even easier to start chatting on Kontalk with your friends
  • End-to-end encryption ensures safe and private conversations, so that only you and the person you are talking to can read them
  • Your and all phone numbers used on the network are irreversibly encrypted
  • It supports multiple devices, making it very easy to start chatting on your phone and continue the conversation on your tablet
  • Based on open standards: XMPP and OpenPGP

The network relies on community donations to keep the infrastructure running, so if you can, please donate on kontalk.net. Even small donations matter.

You can find all permissions used by the app explained at this page.

This version has been stripped of all Google components, meaning no support for push notifications.
