Built for Privacy & Security

Every feature is designed with privacy-first principles to help protect your communications and maintain confidentiality.

End-to-End Encryption

Encrypted voice and video calls with noise cancellation and security verification features to help protect your conversations.

Encrypted File Sharing

Share documents, images, and files up to 2GB with the same level of encryption as your messages. Suitable for sensitive business documents.

Disappearing Messages

Set automatic message deletion timers from 5 seconds to 1 week. Messages are deleted from all devices simultaneously when the timer expires.

Create secure group chats with up to 1,000 members. Admin controls and member verification help maintain group integrity.

Compliance Features

How Our Encryption Works

Your messages are encrypted on your device before transmission and can only be decrypted by the intended recipient. We do not have access to your private keys or message content.

  • Perfect Forward Secrecy: Each message uses unique encryption keys that are automatically deleted after use.
  • Signal Protocol: Industry-standard encryption protocol used by security professionals worldwide.
  • Open Source: Our encryption implementation is publicly audited and verified by security researchers.
  • Metadata Protection: We minimize metadata collection and encrypt what we do collect for operational purposes.
