Viber takes express care of its users’ privacy to ensure the best, smoothest possible experience. Their end-to-end encryption makes sure that no one is able to invade anyone’s privacy and that the texts sent remain only between the parties involved.
However, it does not make it possible to show you who has viewed your Viber profile or check them. It only:
• Use your contacts to detect the profiles of people who use it
• Allow you to delete a contact. The deleted party won’t know about it
• Allow you to block them to prevent any of their messages from reaching you
