A US federal judge struck down some of Apple’s App Store rules on Friday, forcing the company to allow developers to send their users to other payment systems as a partial win for “Fortnite" creator Epic Games and other app makers. 

But the judge did not require Apple to let app makers use their own in-app payment systems, one of Epic’s top requests, and allowed Apple to continue to charge commissions of 15 percent to 30 percent for its own in-app payment system. 

The judge ruled that Apple can no longer bar developers from providing buttons or links in their apps that direct customers to other ways to pay outside of Apple’s own in-app purchase system. The ruling also said Apple cannot ban developers from communicating with customers via contact information obtained by the developers when customers signed up within the app.
