Password Vault - Offline Safe

Password Vault is a 100% offline, zero-knowledge password manager and secure digital vault designed to keep your credentials, logins, and sensitive notes completely private and safe under military-grade encryption.

Unlike cloud-based password managers that store your confidential data on remote servers vulnerable to breaches and outages, Password Vault keeps your data exclusively on your device. Zero internet permissions, zero cloud synchronization, zero tracking, and zero ads.

KEY FEATURES:

• ZERO-KNOWLEDGE LOCAL SECURITY:
Your master password is never stored on disk or in memory unencrypted. Your vault data is encrypted using 256-bit AES-GCM and derived via memory-hard Argon2id and PBKDF2 key derivation functions.

• NO INTERNET PERMISSION REQUIRED:
Password Vault does not request network permissions (android.permission.INTERNET). Your secrets physically cannot leave your phone.

• BIOMETRIC UNLOCK:
Unlock your vault instantly using fingerprint or face authentication backed by Android Keystore hardware protection. Biometric keys automatically self-invalidate if new biometrics are enrolled on your device.

• CATEGORIES & FAVORITES:
Organize your logins and encrypted notes into custom categories (Work, Personal, Banking, Social) with custom icons and quick-access favorites.

• BUILT-IN PASSWORD GENERATOR:
Generate cryptographically strong, uncrackable passwords with customizable lengths and character sets (uppercase, lowercase, numbers, and symbols).

• REAL-TIME STRENGTH METER:
Evaluate password security in real time with our deterministic strength engine that detects common patterns, dictionary words, and repetitions.

• ENCRYPTED PORTABLE BACKUP & RESTORE:
Export your vault into an encrypted .pvault backup container protected by AES-256-GCM authenticated encryption and a custom backup password. Seamlessly restore your vault across devices using the native Android Storage Access Framework.

• PRIVACY & SCREEN PROTECTION:
Screen capture and app preview protection (FLAG_SECURE) prevent other apps and the recent apps switcher from viewing your sensitive vault screens.

• SENSITIVE CLIPBOARD AUTO-CLEAR:
Copies usernames and passwords securely with sensitive content masking on Android 13+ and automatic 30-second clipboard clearing.

• AUTO-LOCK TIMEOUT:
Automatically locks your vault immediately or after configurable inactivity timeouts (30 seconds, 1 minute, 5 minutes, 15 minutes) when the app is backgrounded.

• EMERGENCY VAULT RESET:
Safely destroy all local vault data, preferences, and biometric keys in an emergency with master password authentication.

• MODERN JETPACK COMPOSE UI:
Beautiful, responsive Material 3 interface with dedicated Light and Dark appearance modes.
