This information can be used to create detailed profiles, which may lead to targeted advertising or unwanted surveillance. A large digital footprint increases exposure to privacy risks, making it essential for users to manage their online presence through privacy settings and cautious sharing of personal information. By understanding their digital footprint, individuals can take steps to enhance their online privacy.
