How to Keep an App Out of Siri AI on iPhone

iOS 27.2 added an Excluded Apps setting (Settings → Siri → Excluded Apps) that keeps chosen apps away from Siri, Search and suggestions, so Siri can't read, act in, or answer questions about content in those apps. All apps are included by default, and excluding one also removes its content from Search and stops Siri from using its data for personalization and suggestions elsewhere. The post notes Siri AI is still in beta and that an app's own access to location, photos or contacts is managed separately under Settings → Privacy & Security.
