OneVault pulls every secret into one place that's actually built to keep them unreadable to everyone but you.

what we promise

The rules OneVault is built on

Privacy isn't a setting here, it's the architecture. These are commitments the app keeps by design.

01

We can't read your vault

Your data is encrypted with a key that never leaves your device. There's no server-side copy we could decrypt, even if asked.

02

No account, no profile

OneVault works with zero sign-up. We don't collect an email, build a profile, or run a single tracker or ad.

03

Your master password is the only key

Backups are sealed with a key only you hold, your master password, plus the recovery code you save at setup. Hold neither and not even we can open the backup. That's the point, and you can read the code that does it.

questions

Frequently asked

Can OneVault see my passwords?+

No. Everything is encrypted on your phone and only your master password, or your biometric, can open it. There's no company server that can read your vault, not even us. Backups can only be restored with your master password.

How is my data encrypted?+

Every entry is locked on your device with the same standard of encryption banks use, and only your master password can unlock it. Even if a backup ever leaked, it would be unreadable without your password, so your data is yours alone.

What happens if I switch phones?+

Turn on cloud backup, then restore on your new phone with your master password, or your recovery code if you have forgotten it. Without one of those, no one, including us, can open the backup.

What if I forget my master password?+

We can't reset it, and we never see it, that's what keeps your vault unreadable to anyone but you. So OneVault gives you a one-time recovery code when you set up. Enter it on the lock screen and you're back in, then you pick a new master password. Lose both the password and the code and the vault stays closed, by design.

Can I back up to my own server?+

Yes. Besides Google Drive, OneVault can back up to any server or network drive you control, with the same encrypted, master-password-sealed backup format.

Does it work without internet?+

Yes. Your vault lives on the device, so adding, viewing and autofilling all work offline. The internet is only used for optional cloud backup and on-demand breach checks.

How is it different from saving passwords in my browser?+

Browser-saved passwords are tied to your account and easy to read once you're signed in. OneVault keeps a separate vault locked behind your master password, plus cards, notes, 2FA, leak alerts and more.

Is the free plan actually useful?+

Yes. Up to 50 vault items and 10 two-factor codes, with full encryption and biometrics, no time limit. That is a real vault, not a demo. Upgrade any time to remove the limits.

Can I import from another password manager?+

Yes. OneVault imports CSV exports from LastPass, Bitwarden, 1Password and generic formats.

Which platforms are supported?+

OneVault is on Android today, phones and tablets. More platforms are on the roadmap.
