Post To Timeline - Members Only

I am working with a clean install of Dolphin 7.2.1 and I have noticed that when images are posted to the timeline, they are defaulted to "public" view.  This site will be for members only, and we do not want anything to be viewed by the public, so I am currently looking into ways of removing all options for "public" posting.  Is there a way to change the default "post to timeline" to members only?

Thanks in advance for your time.

Try to run the following SQL query:

UPDATE `sys_privacy_actions` SET  `default_group` =  '4' WHERE `module_uri` = 'photos' AND `name` = 'album_view';

then clear DB cache
