What information does Facebook receive when I use Account Kit?
If you use your email address or phone number to log in to an app with Account Kit, Facebook will send you an email or SMS confirmation code that you can use to log in to the app. In addition to receiving your phone number or email address, Facebook also receives information about the device you're using as well as other information that app developers may choose to share with us in order to use Facebook tools in their apps. Facebook uses all the information it receives to provide and improve its services, including personalising content, tailoring and measuring ads, and providing a safer experience. Please see our
Data Policy for more information about the ways Facebook collects, uses and shares information. Please also review the terms and policies of the app that you're using for additional information about their practices.
