Hello there,
It is very easy to close down your website.
Login to your website as the website owner and go to your admin panel. Click Settings > Main Settings > Archive Website and follow the instructions.
This will fully disable everything, no one will be able to access your website. If at any time you wish to come back or change your mind, you can contact us and we can reactivate the website for you.
Thank you again for using iClanWebsites!
Arnulfo,
