Kontalk Messenger

Kontalk Features:
- 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.
- Both client-to-server and server-to-server channels are fully encrypted. Users can be safe with end-to-end encryption — servers can't decrypt it.
- Your and all phone numbers used on the network are irreversibly encrypted.
