If I install WPMU Dev Dashboard, will my users be able to access it?

I'd like to use the Dev Dashboard on my own Network-wide Dashboard and my personal sites on the WPMU network, (I'm a super-user) but I don't want regular single blog-owners on the network to be able to access it. Will it limit itself to only be accessible to me, as the only WPMU paid member? How about if I have another Super-user on the network - when he logs in, will he have access to the Dev Dashboard under my account?
