Quartz Locker: Offline Vault

Welcome to Quartz Locker, the ultimate completely offline secure vault for your most sensitive data.

In an era of constant data breaches and cloud hacks, Quartz Locker takes a fundamentally different approach: Zero Trust, Zero Internet, and Zero Trackers. We physically cannot see, access, or transmit your data because the app does not even possess the permission to connect to the internet. 100% of your data stays on your device.

CERTIFIED SECURITY & PRIVACY:
• OWASP MASVS Compliant: Strictly adheres to the global Mobile Application Security Verification Standard (Storage, Crypto, Network, Auth, Resilience, and Privacy).
• MobSF Grade A (96/100): Achieved an elite security rating in comprehensive static analysis.
• Exodus Privacy Confirmed: Independently verified to contain absolutely zero trackers and zero internet permissions. Structurally air-gapped by design.

WHY QUARTZ LOCKER?
• 100% Offline: No servers, no cloud sync, no tracking. Your data never leaves your device.
• Military-Grade Encryption: Powered by SQLCipher, your entire database is encrypted natively via AES-256. Every attachment is individually encrypted with AES-256-GCM before storage.
• Encrypted Attachments: Attach ID cards, documents, and photos directly to any vault entry. Up to 3 files per entry, up to 25 MB each.
• Biometric Login: Seamlessly unlock your vault using your device's native fingerprint or face scanning hardware.
• Screen Capture Protection: Screenshots and screen recordings are natively blocked while the app is open.
• Self-Managed Backups: Create heavily encrypted portable backups that you can safely store on a USB drive or your personal computer.
• Auto-Lock & Draft Recovery: The vault automatically locks after 2 minutes of inactivity to protect against unauthorized access. Unsaved entries are securely encrypted in memory so you can resume exactly where you left off.

ZERO KNOWLEDGE GUARANTEE: We have absolutely no way to recover your password. Please remember your Master Password. If you forget it, nobody, including us, can retrieve your data.

Developed with a focus on absolute privacy. A small footprint, beautiful UI, and unbreakable local security.
