Facebook Inc said on Wednesday, April 21,  it is making changes to its advertising tools to comply with an upcoming privacy update by Apple Inc, limiting the effectiveness of data collection features used by advertisers. The world’s biggest social media company has been at loggerheads with Apple’s ‘App Tracking Transparency’ feature, expected to kick in with the latest iPhone software update next week, which allows users to block advertisers from tracking them across different applications.

Apple says it defends data privacy rights, but faces criticism from Facebook, app developers and startups whose business models rely on advertising tracking.

Facebook said on Wednesday the changes on its ad tools would limit the ways in which target audiences can be selected and how the success of an ad campaign is measured.

The company said it is investing in privacy-enhancing technologies to minimize the amount of data collected from users. Facebook and Apple have also tangled over commission fees the iPhone maker charges apps listed on iOS devices, with the social media giant backing small developers most affected by the policy.
