Recipient-keyed sharing, time-bound access, complete audit trail.
“Confidentiality you can defend in a meeting room.”
For founders, agencies, studios, consultants and legal teams handling nda-bound work.
Each shared file is bound to a recipient's public key, not a public URL.
Cryptographically scoped audit trail of who accessed what, when.
No employee, contractor or third party on our side can read your contents.
Isolate NDA work into dedicated encrypted spaces with per-project keys.
A signed NDA assumes the recipient controls who can read the file. The moment that file lives on a provider that can technically read it, that assumption is broken. DRIVUNO removes the provider from the trust list.
No. Files are encrypted on your device before upload using XChaCha20-Poly1305. DRIVUNO servers only ever store ciphertext. The keys required to decrypt your files are derived from your password on your device and never leave it unencrypted.
Zero-knowledge is an architecture in which the service provider has no technical ability to access user data. With DRIVUNO, your master key is derived locally from your password using Argon2id. The server never sees that key, so it cannot decrypt your files even if compelled to.
DRIVUNO uses a different architecture. Google Drive, Dropbox and similar consumer clouds hold the encryption keys to your files, which means their staff, automated systems, and any party with legal access can in principle read your content. DRIVUNO is designed so that this is technically not possible on our side.
Because we cannot read your data, we also cannot reset it for you. You can configure a recovery key when creating your account. We strongly recommend storing it offline. Without your password or recovery key, encrypted data cannot be recovered — by design.
Start free with 2 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
