How to get App data from Graph API when user has access to the app

I want to know how i can access to my app data (title and description) when the user has access to it and get the localized values using the user locale.

My code is this:

    var imageUrl = "http://ift.tt/1yih0QR",
        userID = response.authResponse.userID,
        userLanguage,
        appTitle,
        appDescription;

    if (response.status === 'connected') {

        FB.api(
            "/" + userID,
            function (response) {
                if (response && !response.error) {
                    userLanguage = response.locale;
                }
            }
        );

        FB.api(
            'me/{namespace}:{action}', 'post', 
            {
                object: {
                    "url": imageUrl,
                    "title": appTitle,
                    "description": appDescription,
                    "image": imageUrl
                }
            },
            function(response) {

            }
        );

    } else if (response.status === 'not_authorized') {

        FB.login( function( response ) {
        }, {scope: "publish_actions"} );

    } else {

        FB.login( function( response ) {
        }, {scope: "public_profile"} );
    }

I tried to use this code, but the /me node returns the user data and i want to get the app data:

FB.api(
    "/me",
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);
