If I do not renew my domain name, will my personal data be deleted from the WHOIS database?

If you no longer wish to renew the domain and it is allowed to expire, the contact information will not be immediately removed from the WHOIS database. For .ro domains, there is a period of approximately 90 days (grace period) during which you still have exclusive renewal rights for the domain, and during this period the holder's data will be visible in a WHOIS lookup. For more details related to other domain extensions, you can consult "Domain Terms".
As soon as the domain name has been released by the Registrar and becomes available for public registration, the holder's information will no longer be associated with it.
