I do not understand why I need cloudflair if I purchased a domain within Builderall?

I purchased a domain within the platform I am using. Why do I need to use Cloudflare? Cloudflare also has my personal email address and wants to allow it to be seen by others. Why is this?

I’m not sure why someone would say that. You shouldn’t need Cloudflare just to have a website.

I’m not aware of this. Cloudflare doesn’t show anybody my email address.
