Apple may use certain Siri AI interactions to improve the foundation models powering Apple Intelligence, but users who previously gave permission can change their preference at any time. The relevant control can be found in the device's existing privacy settings.
During the setup process for Siri AI, Apple asks users whether they want to participate in its Improve Siri & Dictation program. Selecting Not Now declines participation without turning off Siri or its AI features.
If a user initially agrees, the decision can be changed later through the same setting. Rather than introducing a separate Apple Intelligence privacy switch, Apple has included the AI training option under the existing Improve Siri & Dictation control.
The setting applies to Siri-related information such as audio recordings, transcripts, associated request data and conversation history stored within the Siri app. However, it does not mean Apple is collecting every interaction handled by other Apple Intelligence features, including Writing Tools and Photos.
How to prevent Apple from using Siri data for AI training
On iPhone or iPad:
Open Settings.
Select Privacy & Security.
Tap Analytics & Improvements.
Turn off Improve Siri & Dictation.
On Mac:
Open System Settings.
Go to Privacy & Security.
Select Analytics & Improvements.
Turn off Improve Siri & Dictation.
Disabling the setting withdraws permission for Apple to store and review Siri audio and saved conversations that were previously opted in for improvement purposes. Importantly, turning it off does not disable Siri AI.
Apple manages this preference separately on iPhone, iPad, Mac and Apple Vision Pro. Apple Watch and HomePod initially use the preference from the iPhone or iPad used during setup, while Apple TV generally inherits the setting unless it is changed manually.
