Secure cloud storage for sensitive documents

The category that demands real encryption Identity papers, tax returns, medical records and contracts are not casual data. They are the files that, if leaked, cause concrete harm.

What "secure" should mean for these files - Encrypted before upload. - Stored only as ciphertext. - Shared with recipient-keyed envelopes. - Retained as long as you choose, with clear deletion semantics. - Not analysed, indexed, or used for any other purpose.

How DRIVUNO fits DRIVUNO is designed specifically for this category of files. There are no productivity gimmicks that require access to your plaintext.

What "sensitive" actually means Sensitive is anything you would not paste into a group chat: tax documents, contracts, IDs, medical records, NDA deliverables, internal financials, source code, client lists, private photos. The common thread is that a leak is not abstract — it has a real cost.

What to demand from a storage provider - Encryption that happens *before* the upload, on your device. - Keys derived from your password locally — never transmitted. - No admin override, no support-team decryption path. - Audited, open primitives (libsodium, XChaCha20-Poly1305, Argon2id, X25519). - Honest metadata policy: what is encrypted, what is not, and why.

Why DRIVUNO Because the architecture above is the entire product, not a checkbox on a marketing page. There is no legacy plaintext mode to fall back to — by design.

A note on long-term reliability Architecture decisions outlive marketing cycles. A zero-knowledge stack built today still holds in five years because the guarantee is mathematical, not contractual. That is the property professionals look for when picking the storage that will hold their most sensitive material — and it is the property DRIVUNO is built around.
