About sketchup license subscription

I will purchase a sketchup pro subscription license. I have a question before that. If I buy a one-year subscription license, can I use two computers? Or is it possible to use only one computer? I understand that classic licenses can use up to two sketch-ups. Are subscription licenses the same as classic licenses? I want to use it with my friends. If not, I will buy two.

you can install on multiple systems but use alternatingly only, i.e. not at the same time.
