Is it possible to clear the localStorage?

Hi everyone, I need to know if it is possible to clear the localStorage when using appium to test on the mobile browser ?

My test is:

'use strict'
var wd = require('wd'), assert = require('assert'), color = require('colors');

function error(err){
  app.quit();  
}

var phone = process.argv.slice(2).shift();
if(phone == undefined) {
  console.log("Phone number not setted!".magenta);
  return;
}

var app = wd.remote('localhost', 4723);
app.init({
  browserName: 'Chrome',
  deviceName: 'Android',
  platformName: 'Android',
  platformVersion: '4.3'
}, function(){
  app.get("http://mcocaro.com.ar/labs", function(){
    app.setImplicitWaitTimeout(5000);
    // I need to clear the localStorage here! <---
    app.elementsByCss('phone-input', function(err, els){
      if(err) error(err);
      else{
        els[0].sendKeys(phone, function(err){
          if(err) error(err);
          else { 
            app.elementsByCss('js-send-code', function(err, els){
              if(err) error(err);
              else {
                els[0].click(function(err){
                  if(err) error(err);
                  else {
                    app.setImplicitWaitTimeout(5000);
                    app.quit();
                  }
                });      
              }
            });
          }
        });
      }
    });
  });
});

As I commented on the code, I need to clear the “localStorage” before setting the input phone number.

Is it possible @jonahss ?
