Facebook to prompt users to accept tracking for personalized ads

Facebook announced on Monday it will begin rolling out a notification for iPhone users globally about how data is used for personalized ads, in an attempt to get ahead of upcoming Apple privacy changes that Facebook claims will hurt its advertising business.

A prompt will tell users that providing access to their activity will give them personalized ads and will support businesses that rely on ads to reach customers.

The social media giant has been waging a public fight against Apple's plan to ask iPhone users whether to allow apps to track them across other websites and apps, warning that Apple's notification "suggest there is a tradeoff between personalized advertising and privacy," and will harm small businesses that rely on Facebook ads. Apple said its pop-up privacy notifications would start appearing on most iPhones in the next few months.
