Data Deletion To comply with the General Data Protection Regulation (GDPR), Facebook allows users to request that your app delete user data obtained from Facebook, thereby giving users control over their data. To respond to this request, perform the data deletion callback. To comply with the General Data Protection Regulations, you must provide the following information: How users request deletion of their data from your app Email addresses users can use to contact you to request deletion of their data Implementation of data deletion callbacks Users should be presented with the option to request deletion of their data after removing an app from the app and website Settings pages. This option comes in two forms: one that allows users to go to a link to get instructions on how to request the deletion of user data, and the other that makes the deletion request. This will replace the current way that users will no longer be able to link to the app privacy policy page.Developers can provide either a data deletion callback service or a link to user data deletion method guidance.
