What is an IDFA
In 2020 Apple announced that along with the iOS 14.4 update, the company planned to give users the opportunity to opt-in to data-tracking, instead of the current model in which users must decline to provide information. It’s part of a policy shift that makes privacy a user’s right, and it will play out in a device-level pop-up asking a user if they would like opt-in to being tracked when they use an app like Facebook.
