USING ALTERNATIVE BROWSER ENGINES IN JAPAN

Summary from the TLDR Dev newsletter

Apple's iOS 26.2 and later now allows alternative browser engines for users in Japan, applicable to both dedicated full browser apps and in-app browsing experiences using an embedded engine. Developers must obtain specific entitlements and meet certain criteria due to the high security and privacy risks associated with browser engines, which handle untrusted content and sensitive user data. Requirements cover functional baselines, security practices like memory safety and timely vulnerability fixes, and strict privacy standards such as blocking cross-site cookies by default.
