One time log in

Hey everyone, I have been trying to create an app, and its working great. The only part which is bugging me is one time login. I tried to implement some methods but i think something is wrong. Please help me out. Any help or modification in the code itself would be appreciated.

Thanks!

app.js

var loggedIn = Ti.App.Properties.getBool('app:isLoggedIn');
 
if(loggedIn){
    var token=Ti.UI.createWindow({
        url:'/token.js'
    });
    token.open();
}
 
 
var win = Titanium.UI.createWindow({  
    title:' Food4Tax',
   backgroundColor:'white',
   exitOnClose:true,
   orientationModes: [Ti.UI.PORTRAIT, Ti.UI.UPSIDE_PORTRAIT]
});
win.open({animated:true});
 
var path = Ti.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory,'/400.png');
var image = Ti.UI.createImageView({
    height : 300,
    width : 300,
    top : 30,
    left : 45,
    image : path
});
win.add(image);
 
 
// Create a Button.
var login = Ti.UI.createButton({
    bottom:30,
    backgroundColor:'#0560A6',
    borderColor: '#0560A6',
    borderRadius: 6,
    color: 'white',
    borderWidth: '2',
    height: 'auto',
    font:{size:12, fontWeight:'bold'},
    width: 300,
    backgroundImage: 'none',
    title:'SIGN IN'
 });
win.add(login);
 
 
 
// Listen for click events.
login.addEventListener('click', function() {
    var loginwin=Ti.UI.createWindow({
        url:'/login.js'
