Just FYI, unless you absolutely need anonymity from ICANN/the country owning the TLD I wouldn’t choose Njalla. Legally any domain you purchase is owned by them, that’s how they can keep your name from law enforcement requests. However, that also means in any dispute between you and Njalla they can just refuse to service you and keep your domain without recourse.
Normal domain registrars are regulated and if you purchase a domain through them you are its legal owner, if they don’t want your service they must still allow you to transfer the domain somewhere else. Any good registrar provides domain WHOIS protection and will only give out your name to legal requests by law enforcement, so I wouldn’t worry too much about that.
No, it’s just something to be aware of
