Add a privacy policy to your Windows 8 based WWA. Note, all of the samples utilized WinJS and I needed a non WinJS version. I don't claim in any way this is novel, but it took me nearly an hour to pull this together since there were no fully baked samples.

PrivacyPolicy.js

        var settingsPane = Windows.UI.ApplicationSettings.SettingsPane.getForCurrentView();
        settingsPane.addEventListener("commandsrequested", foo);

        function foo(args) {
            var cmdPrivacy = new Windows.UI.ApplicationSettings.SettingsCommand("privacy", "Privacy Policy", privacyPolicyInvoked);
            args.request.applicationCommands.push(cmdPrivacy);
        }

        function privacyPolicyInvoked(args) {
            switch (args.id) {
                case "privacy":
                    window.open("http://www.freeprivacypolicy.org/generic.php", "_blank");
                    break;
            }
        }
