title: How to make a site "unique" from each user?
body: <p>I have made a &quot;dating app&quot; website where you can like hard-coded users - just an assignment not implemented in real life:).
  Whenever a user logs in - which it only can if it has SignUp - and likes a hard-coded match it gets saved via local storage. So whenever an other user logs in, that user has the <strong>exact</strong> same site and liked profiles.
  So my question is, how do you save a user action individually on a website - in theory - so not everyone share the same site. Links for articles would also be much appreciated, cause I investigated myself, but couldn't find any usefull articles.</p>
  <p>Thank you for your help in advance!</p>
