Traditional clouds can read you.
DRIVUNO is designed to never have that power.
Not a cloud — your private encrypted vault.
Professional files, confidential projects or personal data — encrypted on your device before they even reach our servers. Only your keys can unlock them.
Where others promise privacy, we enforce it by architecture.
Google, iCloud, Dropbox, OneDrive — they all technically can read your files. DRIVUNO cannot. Your data is encrypted on your device, before a single byte is sent. Our servers see only binary noise.
- They hold the decryption keys
- Automatically scan your content (AI, moderation)
- Forced to comply with authorities
- A database leak = your files in clear text
- Terms allow advertising-driven exploitation
- You are the only holder of the keys
- No scanning, no AI, no access to your content — thanks to a zero-knowledge architecture
- Even with server access, data stays encrypted and unreadable without user keys
- A leak = only random bytes
- No advertising. No data resale. No exploitation of your content.
Zero-knowledge architecture
Your files, file names, messages and recipients are encrypted before sending. No one can read them — not even our engineers.
Internal encrypted mailbox
A 100% end-to-end encrypted mailbox, exclusively between DRIVUNO users. Keys sealed per recipient.
Protected view
Share images and documents in single view: no download, no copy, expiration and automatic watermark.
Local recovery kit
Your recovery key is generated and shown only on your device. Lose it, we can do nothing — that is precisely the point.
Modern cryptography
Argon2id for key derivation, X25519 for sealed envelopes, XChaCha20-Poly1305 for content. Built on modern, recognized cryptographic standards.
European sovereignty
Infrastructure hosted in the EU, GDPR compliant, independent audit. Your data never leaves the territory.
Your data, protected even if a whole provider goes down.
DRIVUNO does not just store your encrypted files — it replicates them. Every vault has a primary copy and an immutable encrypted backup on a separate provider, in a different region (and a different continent when possible). If one provider is banned, breached, or simply offline, your data stays available and stays unreadable.
Primary encrypted storage
Files are encrypted on your device, then stored as ciphertext on Backblaze B2 (EU) with automatic fallback to Supabase Storage.
Hourly immutable backups
Snapshots are wrapped with a separate X25519 master key and pushed to Backblaze B2 with Object Lock — 30 days of write-once retention. Ransomware and account bans cannot delete them.
Cross-continent redundancy
EU primary + JP/EU secondary candidates wired in (OVHcloud, Scaleway, Hetzner, Sakura, IIJ, GMO). Sovereignty modes — Standard, EU Safety, JP Safety, Hybrid, Emergency — switch routing without redeploying.
Provider-agnostic by architecture
Storage, database, payments, auth, email, analytics and CDN all sit behind interfaces. If a provider has to be replaced, ciphertext migrates — plaintext is never reconstructed server-side.
How major clouds handle your files.
Most providers encrypt files after they reach their servers — meaning the provider technically holds the keys and can access content under its own policies. DRIVUNO encrypts on your device, before anything leaves it, so the provider cannot decrypt what you store.
| Provider | Zero-knowledge architecture | Client-side encryption before upload | Provider cannot decrypt stored content | No provider-side plaintext analysis | Encryption keys controlled by user | Off-site immutable encrypted backup |

A private mailbox
designed for confidential data.
Send messages, share sensitive documents, speak without fear. DRIVUNO mailbox is exclusively reserved to platform users. Every message is sealed for each recipient with their public key.
- Subjects, bodies, attachments and recipients encrypted
- Keys sealed per user via X25519
- Metadata minimized and limited to the strict minimum required to operate the service
- No external interoperability — sealed closed circuit
