Security first, always

Your privacy is protected by enterprise-grade security. Zero-knowledge encryption means we literally cannot read your emails.

Core principle

Zero-knowledge architecture

Your emails are encrypted so that we literally cannot read them. Even if we wanted to, even if we were compelled to.

  • End-to-end encryption for email content
  • Encryption keys never leave your device
  • Open-source cryptographic libraries
  • Regular third-party security audits

What we can see

  • Mask addresses (to route emails)
  • Email metadata (for spam filtering)
  • Aggregate statistics

What we cannot see

  • Email content
  • Attachments
  • Your encryption keys
  • Your real email address
