Take Control of Your Digital Privacy with Nebula Vault.
The 100% offline, zero-trust password manager designed for absolute privacy.

In an age of cloud breaches and data leaks, Nebula Vault stands apart by ensuring your data never leaves your device. We ask for Zero Internet Permissions, meaning your passwords are physically incapable of being sent to a remote server.

🤩 Why Choose Nebula Vault?
🛡️ 100% Offline & Private: Most password managers sync your sensitive data to the cloud, making them a target for hackers. Nebula Vault is different. We have zero Internet permissions, meaning your private keys, passwords, and notes can strictly never be sent to a third-party server. You own your data completely.

🔐Transparent Cryptography:
Encryption: AES-256-GCM for authenticated encryption.
Key Derivation: PBKDF2 with HMAC-SHA256 (400,000 rounds).
Native Security: We use the standard Android javax.crypto libraries—no untested custom crypto.

💾Memory Hygiene: Sensitive keys are wiped from RAM immediately after use.

🫆 Biometric & Quick Access: Unlock your vault instantly with Fingerprint/PIN Authentication. We combine security with convenience, ensuring only you can access your credentials.

🤺Mandatory Device Security: To ensure maximum protection, Nebula Vault REQUIRES your phone to have a Screen Lock (Fingerprint, PIN, Pattern, or Password) set. The app will not function on unsecured devices.

⌨️ Anti-Leak Input Fields: We enforce secure input flags that prevent your keyboard from learning, saving, or suggesting your passwords. This ensures your sensitive data is never accidentally stored in your keyboard's history.

🧹 Auto-Wipe Protocol: Forgot to close the app? No problem. Nebula Vault automatically clears sensitive data from the screen when you switch apps or lock your phone or 10 seconds of inactivity, keeping your secrets safe from prying eyes nearby.

📤 Encrypted Export & Backup: We believe you should strictly own your data. Nebula Vault fully supports Encrypted Export so you always have a physical copy of your secrets.
Full Encrypted Backup: Export your entire vault as a secure .nebulavault file for safekeeping.
Standard Encryption: Backups are encrypted using AES-256 with a custom passphrase you verify.
Portable: Move your encrypted backup file securely between devices or store it in your own personal cloud safely.

🧘🏼‍♂️Lightweight & clean:
< 2MB Size: A security app should be small.
No Analytics SDKs: We don't track you.
No Ad Libraries: We don't sell your attention.
No Bloat: Just pure, native Android code.

🛡️Usability & Control:
Incognito Keyboard: Prevents keyboard apps from learning your passwords.
Clipboard Auto-Clear: Automatically clears copied passwords after a simplified timeout.
No Accounts, No Tracking: We don't know who you are, and we don't want to.
