FAQ
Good to know
Do I need an account to use PassKub?
No. The Free tier works fully offline with no sign-in. An account is only created when you choose to enable Premium cloud sync.
Can PassKub read my passwords?
No. Your keypass (master password) never leaves your device, and vault data is always encrypted with a key only you hold — including when Premium sync stores ciphertext on our servers.
What happens if I forget my keypass?
Because we never see your keypass or an unencrypted vault, there is no "forgot password" recovery for the vault itself — keep your keypass safe.
Which platforms are supported?
Android, iOS, Windows, macOS, and Chrome/Edge (with Firefox and Safari extension support). The same encrypted vault format works everywhere.
Can I cancel Premium anytime?
Yes. Premium subscriptions are billed by the store you subscribed through (Stripe, Apple App Store, or Google Play) and can be cancelled at any time from that platform.
