If you use it you can keep it. If you turn off e.g. your email service after 1 year you lose the domain.
This is actually somewhat easier to check than it might seem, because you can buy a domain on any registrar and it won’t have any services associated with it; the hosting or servers pointing to it are completely independent from the domain name which is only rented from ICANN.
