Apple has removed the BitChat app from its App Store in China due to directives from the Cyberspace Administration of China (CAC), which claimed the app contained 'illegal' content. Jack Dorsey announced this on April 5, noting that Apple's notification highlighted the need for apps to comply with local laws. The CAC referenced specific violations related to internet-based information services. While BitChat is no longer available in China, it remains accessible in other regions, and the TestFlight version is also unavailable for testing in China. BitChat operates using Bluetooth technology for messaging without internet access and supports Bitcoin transactions.
