"We believe in thriving and competitive markets where any great idea can flourish. The App Store has been an engine of success for app developers, in part because of the rigorous standards we have in place - applied fairly and equally to all developers - to protect customers from malware and to prevent rampant data collection without their consent.
"We look forward to working with the UK Competition and Markets Authority to explain how our guidelines for privacy, security and content have made the App Store a trusted marketplace for both consumers and developers."
