The developer and mobile advertising technology world breathed a sigh of relief on Thursday after Apple announced it would postpone new privacy restrictions that promised to upend the way advertising works on iPhone apps. The official announcement came after The Information had reported the story. Apple had planned to strictly limit data collection from its devices, data that is key to running the mobile advertising ecosystem. The privacy update was expected to come with the rollout of iOS 14 software this month, which runs on iPhones and other Apple devices. Apple has been an aggressive advocate for new privacy measures, especially in the advertising world, and has cracked down on internet tracking through its Safari web browser, too. Apple’s latest privacy plans with iOS 14 sent a shock through the ad world. Facebook even announced a drastic move, saying it would not collect IDFA information at all. Facebook warned that it would have the biggest impact on publishers and developers that use Facebook Audience Network, the ad network that delivers ads to apps on Apple.
