The privacy option Hide other apps can be used to hide installed apps from clones. This may include original apps as well as other cloned apps.
This is useful if you plan to clone a launcher app that should not display certain apps. Also, an app may be checking for the presence of other installed apps, which causes the app to behave differently or not function at all.
You may either select individual installed apps to be hidden or provide a list of strings, which hides all apps that contain these strings in their package name (the latter requires the large donation).
