That’s a really weird way of putting it. EU ccTLDs don’t offer whois privacy because it’s not needed. They have whois privacy built-in as well as very strong privacy laws.
If you want a .de domain I would recommend using inwx.de as registrar they have extremely low prices for .de and often run discounts for the first year as well.
The one thing to keep in mind if you’re not a German citizen and/or not have a German address is that you need to provide one after you register a .de domain. INWX has a service for 3 eur/yr that will provide one on your behalf.
Some other cheap European domains without any requirements and built-in mandatory whois privacy are .be, .nl, .fr and .ro.
Keep in mind that some of these ccTLD don’t allow purchasing multiple years in advance and also force you to reset your leftover term if you transfer.
If you’re gonna get an European ccTLD you should also use an European registrar like INWX or Netim or Gandi. Using an European ccTLD with an American registrar kind of defies the whole point.
