Apple said the notifications will be mandatory when its iOS 14.5 version becomes available in the coming weeks, though it has not given a specific date.
One-time notifications will require the application developer to request user permission before the app can track activity “across all other companies’ apps and websites.” Experts in the digital advertising industry have said that this warning would cause many users to refuse permission.
Apple announced the move last June, but said in September it would delay the change to give digital advertisers time to adapt. Some engineers are already displaying a notification at will.
Apple said it is giving developers some marketing tools before the change. One tool provides advertisers who use in-app ads to see how many people have installed the app after the ad campaign without disclosing personal information to individual users. Another tool called private click management gives advertisers a way to measure when a user clicks an ad within an app and is redirected to a web page, but without revealing individual user information.
While these tools are intended to be used by software developers, Apple added details about them in one of their privacy policies to consumers on Wednesday.
Facebook had said in December that it planned to show a pop-up notification because it did not want Apple iPhone users to lose access to its apps.
