Internet Corporation for Assigned Names and Numbers (ICANN) rules that when you register a domain, your personal information including name, address, phone number and email are listed in a public WHOIS database. Another ICANN principle says that this information has to be accurate.
Sweet :3 Domain Privacy Protection service legally replaces the Administrative, Technical and Billing contacts of your domain's WHOIS record with generic Domain Privacy Protected contact information.
By having Domain Privacy Protection service, you still retain complete ownership and control of your domain. You can sell, renew, transfer or change settings to your domain name anytime you want.

Owning a domain name automatically lists your personal and contact details in the WHOIS of the domain you hold. The information becomes publicly available. This means that it may expose you to: mass unsolicited commercial emails (SPAM), other junk emails, telemarketing calls, any other known or unknown abuse with your identity information. Domain Privacy Protection shields your personal information from public view, defending you from unwanted solicitations, scams, prying eyes, and worse. This service is applicable ONLY for domain registrations/transfers with Sweet :3.
