If you want to protect your personal information and contact information from appearing when someone is doing a WHOIS search on your domain, you will need to use domain privacy protection activated on your domain name. For now, midphase hosting not offering these domain privacy feature and there is no setting in midphase cpanel that allow you to tweak this as well.
If you really want to have this feature, the only way to do this, is to get the domain privacy protection from third party provider. If your domain name is registered with registrar like godady or namecheap, activating the domain privacy will cost you small amount of money. And once the domain propagation complete, your personal information will be protected, and the registrar contact information is displayed instead.
