What is Skiff?

Skiff provides a complete workspace solution where all your data is end-to-end encrypted. Unlike traditional productivity tools, Skiff never stores unencrypted access to your messages, files, documents, or calendar events. You can sign up, use, and even upgrade your account completely privately - even using an anonymous crypto wallet.

Core Privacy Principles

All messages sent between Skiff Mail users are end-to-end encrypted. Additionally, Skiff never stores unencrypted access to messages sent or received from external mail providers.
Skiff’s privacy model is built on several key principles:
  • Zero-knowledge architecture: Your encryption keys never leave your device unencrypted
  • End-to-end encryption: All data is encrypted on your device before being sent to Skiff servers
  • Open source: The codebase is publicly available for security auditing
  • Privacy-first upgrades: Pay with cryptocurrency for complete anonymity
