Sometimes, we need personally-identifying information in order to provide you with the products and services that you request. Depending upon the product or service, we may ask you for a variety of personally-identifying information. This might include, for example, your name, address, e-mail address, telephone number, gender, and birthdate. We may also ask for other information about you, such as your credit card information (when you are making a purchase), interests, income, or education level. We consider certain identifying information "sensitive." This includes your credit card number, income level, or any other information that would normally be considered confidential.
