Vault

Vault is an open-source iPhone and iPad app for protecting the secrets you cannot afford to lose: 2FA codes, secure notes, recovery details, private keys, and other high-value information. It is fully offline, with no servers or automatic cloud sync, so your data stays under your control instead of drifting into someone else's infrastructure.

When you need a backup, Vault creates encrypted PDF backups that can be saved anywhere or printed to paper and restored later. It is built for serious privacy, including duress-resistant design, hidden items, protective defaults, and no telemetry around sensitive features.
