Vault Zero is a 100% offline password manager and encrypted vault designed to protect your digital secrets directly on your device. Store website logins, app passwords, bank cards, and private notes in one secure vault.

Unlike cloud managers, Vault Zero provides local protection without accounts, cloud servers, or tracking. Enjoy seamless password autofill, automatic login-saving, biometric security, strong password generation, and encrypted local backups under your total control.

No account. No cloud database. Your vault, your privacy.

🔒 WHY CHOOSE VAULT ZERO?

🔐 100% OFFLINE — ZERO CLOUD
Keep sensitive data stored strictly on your Android device. Vault Zero works completely offline without sending vault data to remote servers. No online registration, email, or phone number required.

⌨️ OFFLINE KEYBOARD AUTOFILL & AUTO-SAVE
Log in faster without manually copying and pasting passwords. Vault Zero suggests saved credentials directly above your keyboard and prompts you to save new logins with zero network requests. Your credentials stay on-device without cloud syncing.

🛡️ MILITARY-GRADE AES-256-GCM ENCRYPTION
Protect passwords, bank cards, and private notes with authenticated AES-256-GCM encryption. Master keys are derived locally using 100,000 rounds of salted PBKDF2 key stretching.

👆 BIOMETRIC UNLOCK & SHUFFLE PIN KEYPAD
Unlock your vault using fingerprint or face biometrics, or your master PIN. The randomized numeric PIN keypad rearranges numbers to prevent shoulder-surfing in public.

🗝️ EMERGENCY RECOVERY KEY
Vault Zero generates a 16-character Emergency Recovery Key by default to restore access if you forget your master PIN. Store it in a secure location separate from your device.

❓ OPTIONAL SECURITY QUESTION RECOVERY
Prefer an alternative recovery method? Enable Security Question Recovery in Settings as an optional secondary recovery layer.

🔑 PASSWORD GENERATOR & CRACK-TIME ANALYZER
Create strong passwords and passphrases. Customize length, uppercase/lowercase letters, numbers, and symbols. Check estimated brute-force crack times to verify password strength.

🔍 SMART HINT PRIVACY ANALYZER
Check password hints before saving. The Smart Hint analyzer detects password overlap and sensitive patterns that could expose clues.

💾 ENCRYPTED LOCAL BACKUPS & RESTORE
Export and import password-protected .vault backup archives. Back up encrypted credentials to local storage, PC, USB drive, or SD card without cloud dependencies.

📲 SECURE OFFLINE P2P TRANSFER
