try this way..!

command to install local storage

bower install a0-angular-storage

in index.html

<script src="lib/angular-storage.min.js"></script>

make service :

angular.module('app', ['angular-storage'])
.factory('UserDetailsService', function ( store ,$rootScope) {
    var self = {};
    self.getUsers = function () {
        var users = store.get('_userList');
        if (users){
            return users;
        }else{
            return null;
        }
    };
    self.setUsers = function(UserList) {
        $rootScope.users = UserList;
        store.set('_userList', UserList);
    };
    return self;
});

in controller:

.controller('UserCtrl', function ($scope,  UserDetailsService,store) {
    //to store data..!
    $scope.doLogin = function () {
        $http.post('**** URL *****', $scope.loginData).
            success(function (response) {
                $scope.users = response.result;
                UserDetailsService.setUsers($scope.users);// call to service..!
            }).error(function (response) {
            });
    };
    //to get local store list
    $scope.users = UserDetailsService.getUser();
    //to remove local store data
    $scope.toRemoveLocalData = function () {
        store.remove('_userList');
    };
})

one more simple way ..

you can use local storage , First make a angular factory , then use this angular factory in your ionic app controller , sample code is given below:

Angular Factory ::

 .factory('$localstorage', ['$window', function($window) {
     return {
        set: function(key, value) {
            $window.localStorage[key] = value;
        },
        get: function(key, defaultValue) {
            return $window.localStorage[key] || defaultValue;
        },
        setObject: function(key, value) {
            $window.localStorage[key] = JSON.stringify(value);
        },
        getObject: function(key) {
            return JSON.parse($window.localStorage[key] || '{}');
       }
   }
}]);

Angular Controller :

 .controller('mainCtrl', function($scope, $localstorage) {
       // set data to $localstorage
       // you can use this json data anywhere in your app
       $localstorage.setObject('object_name', json_data);



      // get $localstorage data
      var json_data = $localstorage.getObject('object_name'); 
 });

NB:: localstorage is only for limited data. For large number of data, you better sqlite
