Is it okay to sign up for CommonApp

I have few years before applying to college, but I’m an international student so I wanted to know more about it and get some general knowledge. Is it okay to sign up on that website?

Sure, but don’t fill anything in unless you’re okay with it being deleted this summer. They purge old accounts every year before the new app comes out.

I know it’s a stupid question but to be secure, I don’t have to pay for just signing up on that website, right?

Nope, I think all paying only happens later, when you actually submit apps.
