The file is encrypted on your machine, the link expires within 24 hours, and the decryption key travels in the URL fragment — which browsers never send to a server.
“The recipient opens it. We never could.”
For post-production studios, photographers, architects, law firms and consultants delivering heavy, sensitive files.
Multi-gigabyte files upload in encrypted chunks and resume after a dropped connection or a locked phone.
The fragment after # is never transmitted to our servers, so the link we store cannot decrypt the payload.
Every public link expires within 24 hours, enforced by the database and a destruction job — not by UI politeness.
Add an Argon2id passphrase on top so even the link alone is not enough.
Recipients preview images, video and documents in the browser, decrypted locally, without installing anything.
Access events are logged so you know when a delivery was opened, without logging the content.
Classic transfer tools receive your file as plaintext, keep it readable on their infrastructure for days, and resolve download links server-side. That is fine for a press kit and inappropriate for an unreleased campaign, a case file or a client's raw footage.
The browser encrypts the file locally, uploads ciphertext, and produces a link whose secret part stays client-side. Our servers can prove a blob exists and enforce its expiry; they cannot open it. Behind the transfer you also keep a permanent encrypted vault, so delivery and archive are the same system.
Turn a client folder into a recurring encrypted delivery: Live Clone mirrors it continuously, versions are retained, and each hand-off is a fresh expiring link instead of a permanent public URL.
No. Google Chat encrypts messages in transit and at rest with keys Google manages, so Google can access message content; client-side encryption is limited and not the default. DRIVUNO Rooms is end-to-end encrypted by design: room keys are sealed per member with X25519 and messages with XChaCha20-Poly1305, so we store ciphertext only.
Only for one-to-one calls, and only when enabled. Channel messages, group chats and files in Teams remain readable by the platform. In DRIVUNO Rooms there is no unencrypted mode for channels, DMs or attachments — PSTN phone calls and SMS in the Call & SMS Center are the documented exception and are not end-to-end encrypted.
Transfers are bounded by your plan storage rather than a per-file cap; uploads are chunked and resumable, so multi-gigabyte deliveries are routine.
No. A public encrypted share opens in any modern browser and decrypts locally with the key contained in the link fragment.
Yes. Links can be destroyed immediately, and every link expires within 24 hours regardless.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
