The website provides a search bar where anyone can enter a phone number to access associated information, which may include the owner's name and address. While the full scope of its database is not public, such services typically aggregate data from public records and other sources. The primary users are individuals curious about an unknown caller. The public availability of this information poses significant privacy risks, as it can be exploited for doxxing, stalking, harassment, and identity theft.

To protect their privacy, individuals should be cautious about sharing their phone number online and can request to have their information removed from such databases.
