I found the site and tried to check, but it wouldn't show me anything without being logged in, so I created an account. Now that I'm signed in though, I can only find vague rules, like

The User's account is for personal use only. Only the individual who holds the account is allowed to connect on it. Connections to the User's account are recorded so that we can detect account sharing. The User agrees to keep his login secret, We won't offer technical support for account hacking.

How does this work with a phone or laptop, for example? What if I sign in at my parents house when I visit for a few days?

Can anyone help please?
