Very important! No one can see my schedule!

I am booking up and my jobs are listed on the calendar. Anyone looking at my calendar without creating my account sees that it's wide open. I'm getting done high profile clients that are not happy about this. Please help as soon as possible. I don't want to switch softwares but the reason I purchased this one was that , at a glance, people could see my availability and then decide if they wanted to create an account. Attached is my schedule and what it looks like if you're not signed in.
