So.. are you saying that if you're following this guide here
https://docs.pi-hole.net/guides/dns/cloudflared/ to use Pi-hole with DoH with Cloudflare, that because all requests are queried against Cloudflare, CF still knows what urls I'm looking for, and they can use this information to track me , or build a profile of me.
So, I need to figure out if I want to share my queries with my ISP or Cloudflare?
