We have recently refreshed our branding across our offerings and changed the names of our pricing plans. If you have signed up before Aug 9, 2021, please click Previous plans to view your applicable plans.
We assure you that this change will not impact your product experience, and no action is required on your part.

You can add this script within the <BODY> tag to clear the user information as soon as they close the chat. 

Sample code:

window.fcWidget.user.clear().then(function() {
  console.log('User cleared');
  }, function() {
    console.log("User Not cleared");

However, this might increase the MUV number. This is because after clearing the user info when the same user visits the page again he is taken as a new customer and thereby increasing the count of unique visitors for the account. Customer may be charged extra for exceeding the MUV allowed for their plan.
