First add these using directives to App.XAML.cs:
Second under OnLaunched in App.xaml.cs under #endif put:
SettingsPane.GetForCurrentView().CommandsRequested += SettingCharmManager_CommandsRequested;
Third, add these 2 methods to App.xaml.cs:
private async void OpenPrivacyPolicy(IUICommand command)
Uri uri = new Uri(“http://yourprivacypolicyURL”);
private void SettingCharmManager_CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
Hope this was helpful.
