An encrypted file vault, end-to-end-style encrypted messaging, and per-user encryption keys — for individuals and teams who take data privacy seriously.
Whether it's just you or your whole team — your files, messages, and keys stay yours.
Platform Capabilities
Breach-checked, rate-limited passwords, Microsoft sign-in, and one active session at a time — plus optional two-factor authentication.
Generate your own RSA key pair. Your private key is encrypted at rest, with a verification step that confirms the encryption actually happened — no plaintext keys, ever.
Upload files that are encrypted at rest with AES-256 and stored securely. Everything in your vault is scoped to you — only you can open your files.
Messages are sealed with RSA-4096 envelope encryption and signed, so only the recipient can read them — and they can confirm the message really came from you.
Bring in files from Microsoft OneDrive and Google Drive — connect the storage you already use.
Every file and message event is written to a hash-chained, cryptographically signed log — one you can verify yourself, any time, at /audit/verify.
Transparent Pricing
per additional terabyte per month, over your plan's included storage limit.
