Secure Folder & App Locker

Secure Folder & App Locker is your ultimate local privacy vault, designed to protect your sensitive apps, private photos, videos, and personal files from unauthorized access. Keep your data hidden and secure using a PIN, pattern, or fingerprint authentication.

Disguise your folder as a Calculator, Weather app, or Notes app to completely blend in and keep your secure space invisible to others.

🔒 KEY FEATURES:

◆ App Locker:
Lock any application on your device (social media, messaging, banking, gallery) to prevent unauthorized access. Choose between PIN, pattern, or secure biometric (fingerprint) unlock.

◆ Secure Folder Vault:
Add your critical applications into the Secure Folder to ensure they are hidden and isolated.

◆ Icon Disguise & Aliases:
Transform the app icon and launcher name into a fully functional Calculator, Weather, or Notes app. Enter your secret passcode on the calculator screen to unlock your secure vault.

◆ Fast Fallback Blocker:
If the accessibility service is disabled, the app uses a highly optimized background locker service (with a persistent notification indicator) to ensure your protected apps are blocked immediately.

◆ Local-Only Processing:
Your security is our top priority. All PIN hashes, app lists, and biometric credentials are processed 100% locally on your device. We do NOT collect, transmit, store, or share any personal, behavioral, or sensitive user data.
