Can Clients access my WPMU account and dashboard?

I am starting to install the hub and other plugins to my client sites on a regular basis. I see that when I install your plugin that a menu item appears in the admin navigation of Wordpress. Does this mean that when my client is logged in to the website that they can click through and see the details of all my other clients linked on My Dashboard? I'm hoping the answer is "no." I'm hoping that WPMU is associated with me as a user. Because I would prefer to not have to log out of WPMU on all my clients sites all the time.
