The files of this app are already encrypted by default and not stored in plaintext. They are encrypt with a key using the keychain of the phone. The encrypted config files are in the default app date location.

I am using this library https://developer.android.com/jetpack/androidx/releases/security and that uses AES in GCM mode to encrypt the files. See ProfileEncryption.kt for more details.
