It protects both message content and metadata—including who you communicate with and when—through advanced encryption protocols. Available across iOS, Android, and desktop platforms, SimpleX provides a truly anonymous messaging experience without compromising usability.

Key Features

  • No User Identifiers: The only messaging platform that eliminates user IDs entirely for complete anonymity
  • Double Ratchet Encryption: Military-grade end-to-end encryption with an additional encryption layer protecting all communications
  • Multi-Platform Support: Native apps for iOS, Android, and desktop with command-line interface options

Use Cases

  • Privacy-Conscious Communications: For individuals who prioritize data protection and want to prevent metadata collection
  • Secure Sensitive Discussions: Ideal for journalists, activists, and professionals handling confidential information
  • Anonymous Community Connections: Perfect for support groups, whistleblowing networks, and communities requiring anonymity

Who Is It For

SimpleX Chat is designed for privacy advocates, security-conscious users, and anyone who wants messaging without personal identifiers. It's particularly valuable for individuals in high-risk situations, organizations requiring strict confidentiality, and users who reject traditional messaging platforms' data collection models.
