Meetings, deadlines, invitees and reminders — encrypted on your device, shared only with the people the event is sealed for.
“Your schedule says as much about you as your files. Encrypt it too.”
For teams under nda, legal and medical practices, studios, and anyone whose meeting titles alone would reveal confidential work.
Titles, descriptions, locations and attendee notes are encrypted before they leave your device. The server stores an opaque envelope and a timestamp.
Day-before and one-hour-before reminders, plus conflict detection, computed locally and delivered as push notifications that contain no event content.
Every Rooms channel and Team Drive has its own calendar, sealed for its members. No shared org-wide index, no admin overview of private agendas.
Creating an event posts an encrypted notice in the linked channel, so the team sees it where the work happens.
The same encrypted agenda in the installable app on iOS, Android, macOS and Windows, plus the web.
Removing a member from a channel rotates the calendar key, so future events are sealed under a key they never had.
A calendar is a map of your business: who you meet, how often, at which stage of a deal, with which counsel. Even when a provider does not read the body of an event, an unencrypted title such as 'Due diligence — Project Atlas' is already the leak. DRIVUNO encrypts the content of the event, not just the transport.
Calendars in DRIVUNO are never global. An event belongs to a person, a direct-message thread, a channel or a team drive, and its key is wrapped individually for each member of that scope. If you were not invited and are not a member, there is nothing to fetch and nothing to decrypt.
Push notifications are generated from a signal, not from content: the payload tells your device that something is due, and your device decrypts the details locally before showing them. The notification service never sees the event.
No. Everything in the DRIVUNO suite — files, messages, events, documents, notes, tasks and photos — is encrypted on your device with XChaCha20-Poly1305 before it is sent. Keys are derived locally from your password with Argon2id and wrapped per member with X25519. Servers store ciphertext only.
Those suites encrypt data in transit and at rest, but the provider holds the keys, so content can be indexed, scanned by AI, exported by an administrator or produced on legal request. DRIVUNO is built so that we hold no key that opens your content.
Only the people the item is sealed for. Every room, folder, calendar and document key is wrapped individually for each member with X25519. Removing someone revokes their sealed copy and rotates the key.
Yes. DRIVUNO uses blind indexes: your device computes HMAC tags for names and subjects, and the server matches tags without ever seeing plaintext.
Yes. The free plan includes 1 GB with the exact same zero-knowledge architecture — encrypted drive, Rooms, calendar, docs, notes, tasks and sharing.
Because we cannot read your data, we cannot reset it. You can create a Recovery Kit (printable PDF with QR) when you set up your account and store it offline. Without your password or recovery key, encrypted data cannot be recovered — by design.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
