WPMU-DEV Dashboard in wordpress

Hi, Good day to you. I have 3 websites that installed the dashboard. 2 of them are clients website which I do not want them to gain access to the wpmu-dev dashboard. So I have logged out of it. But what about the plugins that I installed through the dashboard. Can they still function. Also after 1 year of membership subscription, what will happen to these plugin?

Many thanks in advance for ur reply.
