Secure Vault: 100% Offline Password Manager
Secure Vault is a privacy-first, serverless credential manager designed for total peace of mind. Your most sensitive data should never sit on a vulnerable cloud server. With Secure Vault, your data never leaves your device. There are no backend databases, no cloud syncing, and absolutely no "Forgot Password" resets. You are the only one holding the keys.
π‘οΈ Core Functionalities
100% Offline Architecture: Your vault operates entirely without an internet connection. No trackers, no server pings, and zero risk of online data breaches.
Military-Grade Device Encryption: Your accounts, usernames, and passwords are encrypted locally using your unique Master Key.
Biometric Access (Pro): Instantly unlock your vault using your device's built-in fingerprint or face scanner for maximum convenience without sacrificing security.
Organized Data Management: Easily add, edit, search, and delete your credentials. Find what you need instantly with the built-in search bar.
Secure Key Derivation: We use advanced PBKDF2 with unique, cryptographically secure salts to protect your Master Password.
Zero Knowledge: We cannot see, access, or recover your data. Your security is entirely in your hands, which is exactly where it should be.
π How to Guide: Setting Up Your Master Key
Because Secure Vault is offline, your Master Key is the only way to decrypt your data. We cannot recover it for you if you lose it.
Attacking Your Master Password is the only realistic attack vector. If an attacker managed to get a copy of your phone's data, they could find the file containing your encrypted vault and the password-encrypted DEK. Their goal would then be to guess your Master Password.
If your password is weak (e.g., "password123", "88888888"), it could be cracked in seconds or minutes using modern password-cracking tools.
If your password is strong (e.g., a long passphrase with a mix of words, numbers, and symbols like the one suggested in the app's setup), it becomes exponentially harder to crack. A strong 12+ character password could take centuries or millennia to brute-force.
In summary: The security of your vault relies on two things: the proven strength of the AES-256 algorithm and, most importantly, the strength and secrecy of your Master Password.
Make your Master Key strong and secure!
π How to Guide: Portable Backup & Restore (Pro)
Switching phones or want to keep a safe copy of your vault? The Portable Backup feature allows you to export your entire encrypted database as a single, secure text string.
How to Backup:
Unlock your vault and tap the Export (Cloud Upload) icon.
Confirm your Master Key.
The app will generate a highly encrypted text string. Copy this string and save it somewhere safe (like a local notes app, an external hard drive, or a physical piece of paper).
How to Restore (CRITICAL RULE):
Install Secure Vault on your new device.
β οΈ You MUST set up the new app using the EXACT SAME Master Key you used on the old device. If the Master Keys do not match, the backup cannot be decrypted.
