A full mailbox that talks to Gmail, Outlook and everyone else, while messages sit encrypted at rest under keys only you and your teammates hold.
“The inbox everyone else indexes, kept sealed instead.”
For firms, studios and small companies that need normal email with clients, without a provider reading, profiling or indexing the archive.
Your @drivuno address exchanges mail with any provider, with SPF, DKIM and DMARC alignment for deliverability.
Incoming mail is sealed to your public key on arrival; outgoing copies are sealed before they leave the device. Bcc recipients are sealed individually.
Give several members a common address: everyone receives it, and creators can reply and write as that address, each with their own sealed key copy.
Create aliases for projects, clients or signups and retire them without losing the archive.
Tabs, threads, labels, stars, spam, Cc/Bcc, rich composer with drag-and-drop attachments and a docked compose window.
Push and badge notifications tell you a message arrived; the payload never carries the subject or body.
SMTP itself is readable by intermediaries — nobody can change that. What a provider decides is what happens next. DRIVUNO seals every message the moment it lands, so the archive, the search index and the attachments stay unreadable to us.
Team mailboxes are usually shared by handing out one password. Here each member gets their own sealed copy of the address key, with a viewer or creator role, and removal rotates the key.
Subjects and participants are searchable through HMAC blind indexes computed on your device, so the inbox is fast without a plaintext index sitting on a server.
No. Passwords, emails, documents and search indexes are encrypted on your device with XChaCha20-Poly1305. Keys are derived locally from your password with Argon2id and wrapped per member with X25519. Servers store ciphertext only.
DRIVUNO uses blind indexes: your device computes HMAC tags for names, subjects and fields, and the server matches tags without ever seeing plaintext. Results are decrypted in your browser.
Yes. The free plan includes 1 GB with the same zero-knowledge architecture — encrypted drive, Rooms, mail, secrets, docs and search.
Because we cannot read your data, we cannot reset it. Create a Recovery Kit (printable PDF with QR) and store it offline. Without your password or recovery key, encrypted data cannot be recovered — by design.
No. DRIVUNO has no advertising business, performs no content analysis, and cannot train models on data it is unable to decrypt.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
