A master password is both used to access the application and to encrypt the encryption keys, that are generated randomly for each file. Confidential files are accessible directly after the login. With one click on the file, the file is decrypted to a user defined location and can be shown by an installed app for this file type. When you are finished working with the decrypted copy, the file is re-encrypted either automatically or with one confirmation click and the decrypted file is wiped from the storage. This wipe process will overwrite the data with random bytes before the file is deleted. So even if the device is lost or stolen, it is not possible to access your confidential data.
Encrypting new files is very simple: they can be chosen either with the built-in file manager or by simply using the Android "send/share" function from another app.
