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.
When 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.
How to stop Apple from using your Siri data for AI training
On an iPhone or iPad:
- Open Settings.
- Tap Privacy & Security.
- Scroll down and tap Analytics & Improvements.
- Turn off Improve Siri & Dictation.
On a Mac:
- Open System Settings.
- Select Privacy & Security.
- Click Analytics & Improvements.
- Turn off Improve Siri & Dictation.
Turning off the setting withdraws permission for Apple to store and review opted-in Siri audio and saved conversations. It doesn't disable Siri AI.
Apple asks for the preference separately on an iPhone, iPad, Mac, or Apple Vision Pro. An Apple Watch and HomePod initially inherit the choice from the iPhone or iPad used to set them up, while an Apple TV normally inherits it unless the user customizes the setting.
Users can change the setting directly on an Apple Watch, HomePod, Apple TV, or Apple Vision Pro afterward.
What Apple receives when you opt in
Apple's privacy disclosure says it may store audio, transcripts, and related information from Siri, Dictation, and Translate interactions. Related data may include the request category, device specifications, performance statistics, and the device's approximate location.
Apple can use the information to improve Siri, Dictation, Search, Translate, Voice Control, and the foundation models behind Apple Intelligence. A subset may be reviewed by graders, although Apple says only its employees can listen to audio recordings.
Turning off the setting withdraws permissionThe contributed information is associated with a randomly generated device identifier rather than an Apple Account or email address. Apple says the request history isn't used for advertising or sold to other companies.
Apple may retain the information for up to two years. Interactions selected for human review may be kept longer for continued product development.
Apple also says private user data and interactions aren't used to train its foundation models unless the user explicitly chooses to help improve them. Apple updated its model documentation on September 9 to acknowledge the Siri and Apple Intelligence opt-in.
What the switch doesn't stop
Improve Siri & Dictation isn't a master switch for every type of Apple Intelligence analysis. Apple says computer-generated Siri transcripts can still be used to improve Siri and Dictation under its default practices, even when the optional audio-sharing program is disabled.
Apple also gathers privacy-protected, aggregated trends from users who enable Share iPhone Analytics or its equivalent on another device. Those trends can include information about content processed by Apple Intelligence, although Apple says the system doesn't collect individual user data or content.
Users who don't want to contribute those aggregated trends can turn off Share iPhone Analytics under Settings, Privacy & Security, and Analytics & Improvements. On a Mac, the corresponding option is Share Mac Analytics.
Apple doesn't provide a separate analytics switch limited to Apple Intelligence. Disabling the device analytics option also stops sharing other diagnostic and usage information with Apple.
How to delete existing Siri history
Disabling Improve Siri & Dictation stops future participation, but it doesn't remove information Apple already received. Siri history has a separate deletion control.
On an iPhone or iPad:
- Open Settings.
- Tap Siri or Apple Intelligence & Siri, depending on the device.
- Select Siri & Dictation History.
- Tap Delete Siri & Dictation History.
Apple says deleting Siri history removes audio recordings and transcripts associated with the device's current random identifier from its servers. Requests more than six months old and interactions selected for review may no longer be associated with that identifier, so those records may remain.
Deleting Siri history doesn't change the Improve Siri & Dictation setting. Users who want to delete existing information and stop contributing new interactions must use both controls.
