AVG Account Security Question About AVG Ultimate

Hello, 

Me and my Ex bought (split cost) an AVG Ultimate license for 10 devices. 
We are not longer together, and the account was made under his name and email. 

So I was wondering, does he have any sort of an access to my pc, since I am using the shared license for the 10 devices? 

What is exactly visible from his AVG account? Does it say my Mac address, my Ip Address or the name of my PC? Is he able to use this information to access/hack my PC? I am really worried! Any clarification about this would be really appreciated! Thank you.
