A free app for Android, by MobileIdea Studio.

Easy AppLock is a free, easy-to-use app for hiding photos, videos, and other files. With a simple, intuitive interface, it allows you to lock your private content with a simple passcode. 

All files are stored in a safe place, so you can easily recover them if you lose your passcode or your device is stolen. It supports multiple locking methods, including passwords, fingerprint, and pattern, so you can choose the most convenient method for you.

To hide photos, videos, and other files, you can choose to encrypt them and save them to a separate folder. You can also use a separate folder for each type of file. 

The app has a built-in photo editor that can be used to create custom photo-based passcodes. It can also generate random passwords for you.

To protect your files, you can use a separate password for each protected folder. This will prevent anyone from viewing or accessing your private files unless they have the correct password.

It’s important to note that the files you hide will still be stored on your device. They will not be sent to any third party server, and will not be transferred to other devices.
