I did something similar, for similar reasons. In the end I just did whatever to get it published. If you show up at my door, I'll pour you your choice of beer/coffee. But I agree, it feels very invasive!
On the web side of things DNS only recently started being more private - 10+ years ago it was common to have your phone + postal address on whois.
Two take aways from my experience 1. I'm happy that I invested more in the web 2. The app store gives you distribution - I have a few websites with almost 0 traffic, but the app I wrote gets a handful of downloads a week almost 2 years later?

This is the .dk TLD today, and it's the reason I've never posted my website here. The .dk registry (punktum.dk) is run by absolute clowns.
On the other hand, the first thing I do before spending money on a danish website is "whois eksempel.dk", and if it doesn't return a danish address (and wasn't created recently), I'm out.
