Mac

Unlock individual Mac apps using built-in biometric authentication. Keep sensitive data blurred, protect your workspace, and enjoy zero-friction privacy. Supercharge your Mac privacy. Secure sensitive individual applications using built-in biometric authentication, including fingerprint and smart watch sensors, or your account password. Whether you are stepping away from your desk at the office, passing your computer to a family member, or protecting confidential work data, BioUnlock adds an instant, seamless secondary layer of security exactly where you need it most. HOW IT WORKS: Select the specific apps you want to secure (such as communication apps, notes, or mail). The split second those applications come to the foreground, BioUnlock presents a secure, native lock screen. Touch your device's fingerprint sensor or authenticate via your connected smart watch—and you're cleanly unlocked. CORE PRIVACY & SECURITY FEATURES Biometric Unlock: Built directly on local authentication systems. Instantly unlock with the speed of your device's fingerprint sensor or the convenience of an authenticated smart watch. Zero-Friction Fast Locking: Configure global hotkeys to lock all protected windows simultaneously with a swift keyboard shortcut before stepping away. Blurred Background Privacy: The instant an application locks, a translucent blur panel cascades over the window structure, entirely obscuring personal data, texts, or code interfaces from casual onlookers. UNLOCK BIOUNLOCK PRO (In-App Purchase) BioUnlock is completely free to download and use to secure 1 application. Upgrade to BioUnlock Pro to unlock complete unrestricted desktop security: - Protect unlimited applications simultaneously. - Stealth Mode Integration: Run completely invisibly by fully hiding the system menu bar icon. - Anti-Kill Watchdog Shield: Deploys a separate, persistent background helper process that aggressively intercepts unauthorized force-quit attempts to keep your active lock shields secure. - Custom Overlay Text: Personalize the lock text layout for your specific workspace environment. - Launch automatically at system login.
