Hello guys is it possible to use localstorage to deny access from a page when not authenticated when localstorage is null or undefined it will not allow a user to go to a page. Can anyone suggest or help me with this thing thanks

.controller('LoginCtrl', function($scope, $state, $location, LoginService) {
$scope.form = {};
$scope.login = function(){

if((angular.isDefined($scope.form.username)
  && $scope.form.username !== "")
  && angular.isDefined($scope.form.password)
  && $scope.form.password !== "")
{

  LoginService.login($scope.form).then(function(response){
      if(Storage)
      {
      localStorage.setItem('loginDetails', JSON.stringify(response.data.Username));
      $state.go('classattendance');
    } else {
      alert('String is not defined in this browser. please use other storage.');
    }

  }, function(error){

  });
} else {
}

}
$scope.backbutton=function() {
$state.go('home');
}
})
This is the controller that i want to have a permission because even though i didnt login i can access this page.
.controller('ClassCtrl', function ($state, $scope,$ionicPopup, $window, $ionicHistory) {
if (localStorage['loginDetails'] == 'undefined')
{
//alert("Invalid access");
$ionicPopup.alert({
title: 'Access Denied',
template: 'Check username and password'
}).then(function(res) {
$window.localStorage.clear();
$state.go('login')
$window.location.reload();
});
};

$scope.logout=function() {
  $window.localStorage.clear();
  $ionicHistory.clearCache().then(function(){
   $window.location.reload();
   $state.go('login')
 })
};
 })
