Can hackers or anyone see my personal information like my address, my full name, ect. just for owning a domain name?

The reason I ask is because I noticed on GoDaddy they want you to buy this info protector type deal which has lead me to believe if I buy a domain and server, anyone who wants to know can find my address and full name? Is this true? If so, how do they see this? How can I prevent them from seeing this? Hopefully I'm wrong.
