  constructor(public nav: NavController, private http: Http,public loginservice : FromService ) {
        this.nav = nav;
        this.http = http;
        this.local = new Storage(LocalStorage);

        .subscribe(data => {
            this.data.response = data._body;

never ever store user uncrypted credentials anywhere!

everyone can access the localstorage and read the data.

You should use something like oauth or jwt-tokens to keep a session valid.
