Download the app from App Store, and install it on your device. Locate the Crypto tab in the main menu and tap the Free Trial button to get a 14 days free trial. Create a strong enough Crypto Pass to decrypt and view the files in your Crypto Folder. No one, except you, will have access to your Crypto Pass, therefore, once forgotten, it can not be restored. Enter and repeat your Crypto Pass, add a Hint (optional), and tap the Create Crypto Folder button. Once your encrypted folder is created, you can start adding files to it and be sure they are completely protected and invisible to anyone else.
