subscription period

Hello. I've just finished setting up for RHEL8.3 for developer.
I've registered by using subscription-manager and it was done successfully, but I can see that there is something like "Start date and end date". My understanding is that this developer should be free version. Or I still need to register after end of date again??
I mean, there is no expired right?

Status details:
Starts: 03/28/2021
Ends: 03/27/ 2022

Regards,
