About

HVault

Read full description

Vault is a private, local-first password manager with no account and no server. Your encrypted vault stays on your device, protected by your master password and a generated Secret Key. Store logins, payment cards, identities, secure notes, and time-based one-time codes. Use Face ID for convenient unlock and the AutoFill extension to fill credentials in apps and websites. Move from another password manager using CSV or an iPassword Pro backup. Exchange encrypted vault files between devices; imports merge changes instead of replacing the destination vault. Backups are encrypted before leaving the app. Save them to your own iCloud Drive, export them as files, or transfer them directly to a computer over local Wi-Fi. Vault has no backend and cannot see, recover, or reset your secrets. Free use includes up to 20 items. A subscription or lifetime purchase unlocks additional items and backup automation. Existing items remain readable, editable, exportable, and recoverable without a purchase. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
