We take the privacy of personally identifiable information very seriously at Snap, and this more granular birth date and time information is used only for this astrological profile feature. The feature requires exact birth date and time from each person in order to calculate their exact star chart reading. The birth date and time information shown above was actually inputted by the users themselves in order to obtain more specific information, stemming from our latest astrological profiles feature. Snapchat tells The Verge that its Astrological Profile feature is the cause: Snapchat’s Birthday menu has a surprising amount of information about your birth - if you forget you told Snapchat yourself. Checking baby photos will not reveal that the Snapchat Hot Dog has been with you since birth, however. You can view your “Astrological Birthday” in the settings section of Snapchat, and if you weren’t aware you had already given the app all of that information, it would be a fairly alarming discovery. The app’s exact knowledge of the exact time, date, and location of a user’s birth has been an issue of some concern for users on Twitter and TikTok over the last few days, but it’s due to Snapchat’s Astrological Profile feature and not some nefarious new skill the app has gained as it’s soared in popularity over the last year. Despite how things may seem, Snapchat hasn’t learned your birthday or birthplace on its own - you likely told it yourself.
