In the list of settings on the page, find the Access setting:
Access
The access level group that is allowed to view this item.
The default setting is Public, which is everyone that visits your site. This includes both guests and logged in users. To hide this module for users logged in, change the setting value to Guest, which means only guests will have permission to view it. Click Save in the top left of the page to save your settings.
In the screenshots below, both are taken as a logged in user. The left screenshot represents when the Public Access is set, and right screenshot shows the Guest Access set.
