Their privacy policy seems legit[0] but why trust them at all when Pi-hole is an option?
Pricing wise it’s over 2 years worth of service for the price of an original Pi, a good SD card and a case.
The only circumstances where Pi Hole is unquestionably superior is if you are on a network that redirects all DNS requests there are still some ISPs that do that however if you are on such network you probably want to either get off it ASAP or use a VPN.

I run pi-hole on my qnap nas at home since it’s always on anyhow.
One should always have a spare Pi around.
Edit: Oops I didn't wipe the container. Works now!
I've been thinking about running a Pi-hole at home and redirecting all my phone traffic through it via WireGuard.
I also had to manually provision my Android phone on IKEv2 (ipsec), Algo used to provide a strongswan config but unfortunately they dropped this in favour of wireguard. But you can still set it up manually (and on Samsung devices you don't even need strongswan). Wireguard is faster, yes, but my work blocks pretty much every port they don't know, except IKEv2/ipsec because many contractors use it to connect to their work :)
though they do also have some additional security protections for typosquatting, safebrowsing, homoglyphs, threat-intelligence which is also nice. All of which could be done on a pihole though not out of the box when I last used it ~2 years ago.
If you point me at a checkout page for $2/month to not even have to think about plugging a Pi in, I’m going to pull my credit card out in a heartbeat. A single coffee costs me more. Think about your time!
But it's about taking control too. Personally I wouldn't like taking a service even if it were free, over hosting something myself, especially when it's made as easy as Pi-hole does.
Pi-hole is a tool to improve your privacy. Handing all your DNS requests to a 3rd party is the exact opposite. Now you have to deal with their privacy policy, track whether that company got hacked or bought etc.
Installing and maintaining pi-hole takes very little time.
