In newly released documentation, Apple outlined significant changes coming to its App Store in the European Union, while explaining why those changes would be limited in scope. Apple said that enabling alternative app stores and payment options in the EU could open the door to “malware, fraud and scams,” compromising user security.

“We’re limiting these changes to the European Union because we’re concerned about their impacts on the privacy and security of our users’ experience – which remains our North Star,” Apple said.

Under the new EU regulations, Apple will allow developers to use alternative payment systems and direct users to third-party app stores. However, Apple stressed that these new avenues posed risks.

“If not properly managed, alternative distribution poses increased privacy, safety, and security risks for users and developers,” the company said. “This includes risks from installing software from unknown developers that are not subject to the Apple Developer Program requirements.”

To mitigate risks, Apple will require alternative EU app stores to implement malware scans. However, Apple conceded its diminished ability to screen apps and assist users under the new system.

“Apple has less ability to address these risks, and to support and refund customers regarding these issues,” the statement read. “Even with safeguards, many of these risks remain.”

Apple said it would engage developers, users and EU regulators on potential App Store impacts going forward. Analysts expect alternative app stores to account for a small share of the total EU iOS app market initially.

For iPhone and iPad users outside the EU, the App Store and in-app purchase system will operate business as usual, with no changes on the horizon.
