The Password Locker

Pesystems LLC

About this app

Your passwords belong to you. Not to a company, not to a server, not to a subscription.

The Password Locker keeps your account information in an encrypted vault on your own device — and that is the entire design. There is no account to create, no cloud to sync with, and no monthly fee. There is nothing to breach, because there is nothing stored anywhere but your phone.

VERIFY IT YOURSELF

This app is built without the Android internet permission. It is not that we promise not to send your data anywhere — the app is technically incapable of it. Check the permission list on this page: the only permission requested is optional biometric unlock.

REAL ENCRYPTION

• AES-256-GCM authenticated encryption protects every record
• Your master password is never stored — anywhere, in any form
• Keys are derived with PBKDF2-HMAC-SHA256 at 600,000 iterations using a unique random salt
• Tampered or corrupted data is detected and rejected, never silently accepted

BUILT FOR EVERYDAY USE

• Organize accounts into folders that make sense to you
• Search your whole vault instantly
• Generate strong passwords when you need a new one
• Show or hide a password as you type it, so you can check your work
• Copy a password with one tap — the clipboard clears itself automatically
• Unlock with a fingerprint or face instead of retyping your master password
• The vault locks itself when you step away

YOU WILL NOT GET LOCKED OUT

• Create an optional emergency recovery key and keep it somewhere safe. It can reset a forgotten master password.
• The app keeps encrypted daily backups on your device automatically
• Export a portable encrypted backup and store it wherever you like — another device, a drive, a safe. It stays encrypted and still needs your master password to open.

PRIVACY THAT IS NOT JUST MARKETING

• No accounts, no registration, no email address required
• No analytics, no tracking, no advertising, no third-party SDKs
• Screenshots and screen recording of the app are blocked
• Android's own cloud backup of app data is disabled, so your vault is never copied to Google's servers
• Uninstall the app and every trace of the vault goes with it

A NOTE ON RESPONSIBILITY

Because your vault is stored only on your device and we keep no copy, we cannot recover it for you. Choose a master password you will remember, create a recovery key, and keep a backup somewhere safe. The app makes all three easy — but the responsibility is yours, and that is the trade that keeps your passwords private.
