This might be a stupid question for someone who is not technical, but what is the use of using a DNS server such as Quad9 for home use? Does it help with privacy? If so, how does it do that?
I tried to google around but all the articles are fairly technical.

DNS, or Domain Name System, is kinda like a phone book. You can go in and find the address of a website that you want to visit just by knowing its name/domain.
For example, “google.com” isn’t a real address, but rather a name we gave to the address to make it easy to remember the website.
When you want to go to Google, your browser goes and asks a DNS server for Google’s address and loads the website using that address.
Just like looking up a business’s phone number and calling them.
Quad9 is a DNS provider who advertise privacy and security if you switch. However, the privacy argument is moot.
Because DNS works by having you ask for addresses, any DNS provider can store that information. Changing your DNS just changes who has access to that info.
Quad9 says their DNS is private because you’re not using your ISP’s DNS (which may or may not be logging/or selling your data).
