Good question. When you request a free reading, your date of birth (and Zodiac sign) is used to determine which free Zodiac reading to send you. If you enjoy your free Reading, you will then have the option to purchase a more in-depth and personalized Astrological Reading and the personal data you've provided will again be used, along with any additional data that may be needed, to create your personalized reading.
There are a number of products and services that are sold here at Astrology Answers and because each is unique, each may require different pieces of personal information to complete. With that in mind, you may be asked for additional information other than that specifically mentioned above. In most instances though, the personal data we ask for is required to create and customize the products and services you've requested.
To see how your birth date is used to determine which free Zodiac Reading is best for you, please view this sample reading. Your free reading will be similar, but may not be identical as it will be based on your birth date, and will contain information most useful to you.
