title: Save last state of radio buttons in a simple web app. Do I need a database?
body: <p>I have a simple web page with three radio buttons that, once checked, thanks to onChange() function, the application does things.</p>
  
  <p>Now, I need to save the last state of the three radio buttons. Basically, I need to know which was the latest checked radio button.</p>
  
  <p>The application will be accessible from different browsers from only one person so, there aren't issue involving multiple people changing the status at the same time.</p>
  
  <p>I've found this question here
  <a href="https://stackoverflow.com/questions/28574404/save-state-of-radio-buttons-javascript">Save state of radio buttons javascript</a>
  but, as soon as I need the data "in the cloud", I can't save it on memory browser or in local on the pc</p>
  
  <p>Am I forced to use a database to store this only data or, am I missing something?</p>
