Short answer
For Cloud Vault photos and videos, zero-knowledge mean say our team no get secret wey we need to decrypt content. Device encrypt files before upload with key wey come from Cloud Vault password. You need same password to remove Cloud Vault encryption layer for another device.
We fit store encrypted backup without being able to open your photos.01 / 04
Start with who hold key
“Encrypted” tell you say cryptographic process protect data. The word alone no tell you which people or services fit decrypt am. Useful question na: provider fit get the secret wey e need to open files?
For Cloud Vault photos and videos, our team no fit. Na this specific privacy property we mean by zero-knowledge. E no mean say service no get account information, billing records or other operational data.

Your phone encrypt before upload
Your files already use AES encryption for app. Cloud Vault add another AES-256 encryption layer locally before files leave device. Key wey come from Cloud Vault password protect this extra layer; password no dey go our servers.
Imagine say you send locked container go storage but keep the way to open am yourself. Storage service fit keep container without reading wetin dey inside. This example explain access boundary; actual protection na encryption, no be picture of lock or hidden folder.

Open backup for another device
For another device, Cloud Vault password recreate key wey remove Cloud Vault layer locally. Files wey dey app remain encrypted. Cloud Vault support backup and sync between iPhone and Android.

Choose strong cloud vault password
Cloud Vault use Argon2id for password hashing. Hashing make guessing attempts cost more, but e no make predictable password safe. Long, random password wey you no reuse make the encryption key wey come from am harder to guess.
Save Cloud Vault password before you rely on backup. Our team no fit recover am. App unlock code dey separate, so to recover am no recover cloud password. Na practical result of not giving us the secret wey we need to read your content.
