Zero-knowledge encrypted cloud storage for secure file management
Vault Desk is an end-to-end encrypted cloud storage service designed for individuals and organizations seeking maximum privacy and security. It encrypts files on the user's device before upload, ensuring that the server only stores unreadable ciphertext and wrapped keys, making it impossible for anyone, including Vault Desk, to access the content. The platform supports secure sharing, passwordless login, and account recovery without compromising encryption keys, providing a private and user-controlled file vault accessible via web and mobile apps.

Vault Desk has zero knowledge of your file contents because encryption and decryption happen entirely on your device; the server only stores ciphertext and wrapped keys.
You receive a one-time recovery key at sign-up that independently unlocks your account and re-wraps your keys under a new password on your device.
No, even if the server is compromised, only encrypted blobs and wrapped keys are exposed, which are useless without your password.
Yes, Vault Desk uses well-reviewed cryptographic primitives from libsodium and a small auditable crypto core shared across platforms.
Encrypted blobs are stored in object storage and encrypted metadata and wrapped keys in the database; the data is meaningless without your keys.
