There are number of options available to add your own branding to the SpreadsheetWEB Control Panel. You can replace the SpreadsheetWEB logo that is on the login screen, as well as those that are on the Control Panel. You can also change the styling of Control Panel pages by customizing the stylesheets for your applications. If you have your own domain, you can use this with your server configuration to make your web applications use it instead.
Note that branding options like logo and domain replacements are available only to private cloud and server license customers.
