Back to your question, Settings belong to Qt.labs.settings wich is not available in Sailfish, so you have to use
ConfigurationGroup, here is a sample program that should work (untested )

Code:
import Nemo.Configuration 1.0

Item {

	Rectangle {
		id: rect
		anchors.fill: parent
		color: '#000000'

		MouseArea {
			anchors.fill: parent
			onClicked: rect.color = Qt.hsla(Math.random(), 0.5, 0.5, 1.0);
		}
	}
	
	
	ConfigurationGroup {
        id: settings
        path: "/apps/harbour-yourApp"
    }
	
	Component.onCompleted: {
		rect.color = settings.value("rectColor", "#000000")
	}
	
	Component.onDestruction: {
		settings.setValue("rectColor", rect.color)
	}
}
From the docs:
variant value(string key, variant defaultValue, int typeHint)
Returns the value of key as a variant. If key does not exist defaultValue will be returned.
The line
rect.color = settings.value("rectColor", "#000000")
tries to load the value of rectColor, if that doenst exist (at the first time it wont) it will load the default value "#000000". The rest is pretty straightforward, on destruction the last rectangle color will be saved in rectColor string. While reading the docs is important, I have to agree that this particular documentation about ConfigurationGroup is very poor.
Feel free to ask any more questions if something is unclear to you, and keep on coding

Cheers
