E2e ensures that even your service provider, leave alone governments and agencies, cannot access your conversations on their servers.

  • Multi-mode communication

This allows users to send messages through videos, audios, and text. Simply put, it allows users to communicate through multiple modes. Users can also delete any form of communication that comes through.

  • Multi-platform support

Encrypted messaging apps offers an opportunity to synchronize messages across web, desktop, and mobile platforms.
