You can use Windows.Storage.ApplicationData for this.

Example:

var applicationData = Windows.Storage.ApplicationData.current;

var userSetting= applicationData.localSettings.values.userSetting;

//First run ? set default value
if (userSetting) == "undefined"){
    applicationData.localSettings.values.userSetting= 1;
