Linking the domain without subscription

Hello, please put the domain working without subscription

Because I subscribed and worked for a whole month on the site and bought a domain

In the end, when the subscription stops, the site does not work on my domain

I built the site and finished. I will not benefit from the subscription. Should I subscribe only for the site to work on my domain without benefiting from it? Please modify this point because I will look for an alternative for you if it is not solved. Thank you.
