You can find your purchase code in the confirmation email you received after completing your purchase on the CodeCanyon or Bookly website.
If you purchased Bookly through CodeCanyon, read here how to find your purchase code.
If you purchased directly on the Bookly website, your purchase code was sent to the email address you used during checkout. Search for an email from Bookly with the subject line "Thank You for Your Purchase!".
Your purchase code is also available in your Bookly Cabinet, which is created automatically at the time of your first purchase. Login credentials for your cabinet are sent to you via email.
