Apple can use your Siri AI interactions to improve the foundation models behind Apple Intelligence if you opt in, but you can withdraw that permission later. Here’s where to find the toggle in settings.
Apple IntelligenceWhen setting up Siri AI, Apple asks users whether they want to join Improve Siri & Dictation. Choosing “Not Now” declines the request without disabling the assistant.
Users who initially agree can change their decision later. Apple documents the training setting under the existing Improve Siri & Dictation control instead of providing a separate Apple Intelligence switch.
The setting covers Siri audio, transcripts, related request data, and conversation history saved within the Siri app. It doesn’t give Apple permission to collect every interaction processed by Writing Tools, Photos, or other Apple Intelligence features.
