‘IDFA’ stands for ‘Identifier for Advertisers’. It’s a unique ID present on every Apple (iOS) phone. It can be used by apps on your phone to identify you, and provide data on how you are using that app.
From iOS release 14.5 (April 2021), Apple changed the way IDFA works. Apps on your phone can now only use your IDFA if you give them your permission. You have to authorise this individually for each app.
At Yoti, we want to understand more about how you use the app, particularly how you came to find and download the app. So the Yoti app will ask for your permission to use IDFA. This will involve sharing anonymous data with our ad partners to help us understand the performance of our campaigns. We’ll also use this information to make sure we don't show you one of our ads after you've downloaded the app. We will never sell this information to advertisers.
