About this app

Picture AppLock - Photo PIN
Are you tired of standard PINs and predictable pattern locks that anyone looking over your shoulder can easily memorize? Meet Picture AppLocker, a unique app locker that turns your favorite photo into a highly secure, invisible password. Protect your privacy and lock your apps with a personalized picture code that only you know!


How Picture AppLock Works
It’s incredibly simple yet highly secure. Just select any image from your gallery and tap on three specific locations (for example: a person's eye, a tree branch, or a car tire). These three invisible touch points become your unique "Photo PIN/Code". Whenever you open a locked app, your chosen image appears on the screen—just tap your three secret spots to unlock it. Intruders won't even realize they are looking at a lock screen!


Top App Features
Invisible Picture Code: No numbers or visible patterns to trace. Intruders, friends, or family won't be able to guess your password, even if they are watching you unlock your phone.
Lock Any App: Secure your personal messages, social media, gallery, email, and banking apps with a single tap.
Customizable Match Accuracy: Adjust the touch radius from a standard size to high-precision mode, ensuring nobody can unlock your apps with lucky random taps.
Auto-Lock Timer: Choose to lock apps immediately after closing them, or set a grace period (e.g., 30 seconds or 2 minutes) for a smoother experience.
Biometric Recovery: Don't worry about forgetting your secret spots! Use your device's native fingerprint or face unlock to reset your App PIN securely.
Uninstall Protection: Prevent unauthorized users from bypassing your security by trying to delete the app locker.


Privacy First Security
We believe your security should never compromise your privacy. Picture AppLock operates with a strict, privacy-first architecture. All of your core security data—including the photos you select, your secret tap coordinates, and your app usage history—is processed and stored 100% locally on your device. We do not transmit, upload, or have any access to your chosen photos or picture codes.


Upgrade your digital security today. Download Picture AppLock and experience the ultimate blend of personalized design and unbreakable privacy!

Hi, We're sorry that you're experiencing this issue. We think you haven't disabled "Battery Optimisation" for this app. Please click on the 'Warning' that is displayed on the main page of this app. Once you disable "Battery Optimisation", the system will not automatically close the app in the background. Thanks for your understanding.
