WARNING: Do not use this product if you are not a professional or your work does not require extreme secrecy. This application is designed specifically for specialists who work in highly sensitive environments, such as journalists, government officials, secret service agents, and others.

With this pro version, you can have all the features you have in the free version, plus some more advanced ones:

1. Encryption: All files are encrypted so that even if bad actors have access to your files, they still cannot open them.
2. Extra protection with your device's lock screen.
3. "Kill-switch" code to erase all data in case of emergency: Imagine someone forces you to open the app; you can use this code to erase everything before the app is opened. (Don't worry, you can recover the data later because you have the next feature.)
4. Backup and Restore.

No launcher icon and no appearance of the application anywhere on your phone. Others do not even know you have this application on your phone. That's why it is perfect for hiding your photos, videos (and other sensitive data).

Only you can access the application and manage your hidden files by calling the application from your phone dial with your own "Android secret code."

Just dial: *#*#CODE#*#* (where CODE is any series of numbers you set) from your default Phone application. This application will *magically* appear at your disposal.
