Many users complain the app won't work and clipboard messages still appear on the soft keyboard.
That's because some soft keyboard apps stores every clipped message (clipboard history). Since this app is just a simple naive little app that achieves cleaning by set clipboard to an empty message it can't touch those keyboard apps content.
If you're concerned about your clipboard security use a soft keyboard app that doesn't store clipboard content(such as Gboard as far as I know).
