Your credentials.
Your Drive.
Zero knowledge.
Vaultaro stores your encrypted vault in your own Google Drive. No servers. No subscriptions. Mathematically impossible for anyone but you to read — not even us.
Features
Everything you need. Nothing you don't.
Designed around one principle: your data belongs to you, and only you.
Zero-Knowledge Encryption
AES-256-GCM encryption with Argon2id key derivation. Your master password never leaves your device — only the encrypted ciphertext is ever stored.
AES-256-GCM + Argon2idYour Google Drive, Your Vault
The vault file lives in your own Google Drive. We never touch your data. No proprietary cloud, no vendor lock-in — you own the file completely.
Drive v3 APIBiometric Unlock
Face ID, fingerprint, or device PIN. Unlock instantly without re-typing your master password every time. Biometric data never leaves your device.
local_authMulti-Language Support
Use Vaultaro in your preferred language. Switch instantly from the settings tab with no restart needed — more languages continuously added.
Multi-languageSelective Sharing
Pick exactly which fields to share from any vault entry. Review what will be sent before it leaves your device — sensitive values stay masked until you reveal them.
Field-level controlRecovery Key System
A one-time recovery key lets you regain access even if you forget your master password — without any server involvement. Store it somewhere safe.
Self-custodyHow it works
Up and running in three steps
No account creation, no email verification, no credit card. Just Google Sign-In and you're ready.
Sign in with Google
Tap "Continue with Google" and pick your account. Vaultaro gets access only to files it creates in your Drive — nothing else.
Drive-scoped OAuth 2.0Create your vault
Set a strong master password. A unique recovery key is generated and shown once — write it down and store it somewhere safe.
Argon2id key derivationStart storing securely
Add credentials, card numbers, bank accounts, and more. Everything is encrypted on-device before it ever reaches Google Drive.
AES-256-GCM on-deviceSecurity
Built on cryptographic foundations
No hand-rolled crypto. Every primitive is a battle-tested standard.
Industry-standard authenticated encryption. Provides both confidentiality and integrity in one pass.
Memory-hard KDF, winner of the Password Hashing Competition. Resistant to GPU and ASIC brute-force.
Tuned for ~500 ms on a modern phone — slow enough to deter attackers, fast enough for your daily unlock.
Every vault write includes a SHA-256 hash of the ciphertext to detect accidental corruption or tampering.
AAD is bound to every AES-GCM operation, preventing ciphertext from being silently re-used across contexts.
Vault key bytes stored in the OS keychain (Android Keystore / iOS Secure Enclave). Never plaintext on disk.
Our security guarantees
- Your master password never leaves your device
- Vaultaro servers do not exist
- Google Drive stores only encrypted ciphertext
- Recovery key is shown once and never stored by us
- Changing your password preserves the same vault key
- Clipboard auto-clears 30 seconds after any copy
