Keys live on your device
Your master key is derived locally from your password. It is never transmitted, stored, escrowed, or recoverable on our side.
Privacy architecture
Privacy by architecture
Confidentiality you can verify in the design — not just in the privacy policy.
Servers see only ciphertext
Uploads, attachments and messages are sealed before they leave your device. Our servers store opaque blobs.
Metadata is minimised
We retain only what is needed to run the service: account identifier, quota, billing status, and security/audit logs. See the metadata policy for the full list.
No content analysis
We do not scan, parse, classify or train on user content. There is nothing readable to scan.
No advertising business
DRIVUNO has no advertising revenue. There is no incentive to look at your data.
Frequently asked questions

We can disclose ciphertext and the limited metadata we retain. We cannot disclose plaintext contents because we do not have the keys required to decrypt them.
Your sensitive files deserve more than a traditional cloud.
