Security & Privacy Architecture

Vaulto is built on a Zero Knowledge foundation. We don't have your keys, so we can't read your notes. Here is exactly how it works under the hood.

Local Encryption

Your data is encrypted on your device using AES-256-GCM before it ever touches our servers. The encryption key is derived from your Passphrase.

constkey = await crypto.subtle.deriveKey(
passphrase, salt, iterations, algorithm,
true, ['encrypt', 'decrypt']
)
constenc = await aes.encrypt(
noteContent, key
)

Private & Sovereign AI

Data leaves your device only when required for AI processing. Protected by military-grade encryption in transit.

The Master Key

Your Master Key is a random 256-bit key generated locally. It is encrypted with your Passphrase before being backed up. We store only the unreadable, encrypted bundle. Without your Passphrase, your data remains mathematically inaccessible to everyone.

Encrypted Sync

Your data is synced securely between your devices. The cloud stores only encrypted data. To unlock it on a new phone, simply enter your Passphrase.
