Encrypted password vault with zero-knowledge security.
Read full description
Prün is an encrypted password vault that helps you find and clear out the logins you no longer need.
YOUR VAULT, ENCRYPTED ON YOUR DEVICE
AES-256-GCM authenticated encryption with a key derived from your master password (PBKDF2, 600,000 iterations). Tampered vault data is detected and rejected. Your master password never leaves your device and cannot be recovered, so keep it safe.
IMPORT IN MINUTES
Apple Passwords, 1Password, Bitwarden, LastPass, Chrome / Google, Edge / Microsoft, or any CSV.
KEEP WHAT MATTERS
Passwords, API keys, SSH keys, tokens, certificates and database credentials. Search, filter, and delete what you no longer use. Auto-lock after the idle time you choose.
AI PRUNING INSIGHTS (PRO)
Surfaces stale and duplicate credentials and ranks what to clean up first. Pro AI sends credential metadata (type, category and how old each entry is) to a third-party AI model. Names, usernames and passwords are never sent.
FREE AND PRO
Free holds up to 25 credentials. Pro unlocks unlimited credentials and AI pruning insights for $4.99 per month or $29.99 per year, with a 7-day free trial on the annual plan. Prices may vary by region. Subscriptions renew until canceled in Google Play.
