Prün — Password Pruner
Zero-knowledge password vault
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Easier password import: port passwords over from Apple Passwords,1Password, Bitwarden, LastPass, Chrome, or Edge in a few taps. Better biometric diagnostics in Settings.
Prün is a zero-knowledge password manager built for people who take security seriously.
Your vault is encrypted entirely on your device using AES-256-GCM with a master password only you know. Prün never sees, stores, or transmits your master password or unencrypted credentials. This is the same dual-layer architecture used by 1Password and Bitwarden — only you can decrypt your vault.
SECURITY
• AES-256-GCM encryption with PBKDF2 (600,000 iterations)
• Zero-knowledge architecture — your master password never leaves your device
• 24-word recovery key for vault backup
• Diamond-grade security hardening with anti-tamper protections
• Secure Enclave integration for biometric vault unlock (Face ID / Touch ID)
SIGN IN YOUR WAY
• Sign in with Apple, Google, or Microsoft
• Email and password authentication
• Your identity provider handles sign-in; your master password handles encryption — they are separate layers

WHY PRÜN
Most password managers ask you to trust them with your secrets. Prün is built so you don't have to. Your master password derives the encryption key on your device. The cloud only ever holds an encrypted blob it cannot read.
Prün is open about what it does and doesn't do. Your data is yours.
