How to Keep an App Out of Siri AI on iPhone with iOS 27.2 Excluded Apps

iOS 27.2 adds an Excluded Apps setting that keeps chosen apps away from Siri, Search and suggestions in one place, replacing the several per-app switches needed before. Excluded apps stay installed, but Siri can no longer read their data, act inside them, surface them in Search or use them for suggestions, and onscreen awareness stops working there. The setting lives under Settings → Siri → Excluded Apps and requires iOS 27.2 or later; Siri AI itself remains in beta and is unavailable on iPhone in the EU.
