Businesses use this information to help complete a transaction, remember your preferences, deliver personalized content or special offers, or save you time.
Transactions such as signing up for a service or buying something are linked to you—for example, by a shipping address or credit card number. But in most cases, businesses generally collect data that does not identify you by name. Sites track which web pages you visit and the clicks of your mouse, but not you personally.
Personal details about you may be also online because you may have added your own information in resumes, chats, pages on social sites like Facebook, or comments in discussion groups or on Twitter.
Others may have published information about you. Friends may write about you or post photos of you and your family. Records of government agencies are searchable—for example, photos of your house and its value, your birth certificate, and copies of your signature. Church groups, clubs, and professional associations may reveal your full name, workplace, and donation history.
