When you make requests, Siri sends certain data about you to Apple to help respond to your requests
When you use Siri and Dictation, the things you say and dictate will be sent to Apple to process your requests. In addition to these audio recordings, your device will send other Siri Data, such as:
- contact names, nicknames, and relationships (e.g., “my dad”), if you set them up in your contacts;
- music, books and podcasts you enjoy;
- names of your and your Family Sharing members’ devices;
- names of devices and members of a shared home in the Home app; and
- the names of your photo albums, apps installed on your device, and shortcuts you added through Siri.
Your requests are associated with a random identifier, not your Apple ID.
Siri Data, which also includes computer generated transcriptions of your Siri requests, is used to help Siri and Dictation on your iOS device and any Apple Watch or HomePod set up with your iOS device, understand you better and recognize what you say.
Siri Data is associated with a random, device generated identifier. This random identifier is not linked to your Apple ID, email address, or other data Apple may have from your use of other Apple services.
Siri Data and your requests are not used to build a marketing profile, and are never sold to anyone.
If you have Location Services turned on, the location of your device at the time you make a request will also be sent to Apple to help Siri and Dictation improve the accuracy of its response to your requests.
Only the minimum data is stored by Siri on Apple servers
By default, Apple stores transcripts of your interactions with Siri and Dictation and may review a subset of these transcripts. You can opt in to have the audio of your interactions with Siri and Dictation stored and reviewed by Apple employees to develop and improve Siri by going to Settings > Privacy > Analytics & Improvement > Improve Siri & Dictation.
Your request history is associated with the random identifier for up to six months. Your request history may include transcripts, audio for users who have opted in to Improve Siri and Dictation, and related request data such as device specifications, device configuration, performance statistics, and the approximate location of your device at the time the request was made. After six months, your request history is dissociated from the random identifier and may be retained for up to two years to help Apple develop and improve Siri, Dictation, and other language processing features like Voice Control. The small subset of requests that have been reviewed may be kept beyond two years, without the random identifier, for ongoing improvement of Siri.
Your Siri settings will sync across your Apple devices using end-to-end encryption if you use iCloud. If you have set up Hey Siri, a small sample of your requests will also sync using end-to-end encryption to improve personalized Hey Siri recognition on each device.
You have choice and control
You can turn off Ask Siri or Dictation at any time. To turn off Ask Siri, open Settings > Siri & Search, then slide the Listen for “Hey Siri” and Press Home or Side Button for Siri switches to “off”. To turn off Dictation, open Settings > General > Keyboard, then slide the Enable Dictation switch to “off”. If you turn off both Ask Siri and Dictation, Apple will delete Siri Data that is associated with the random identifier.
Request history associated with a random identifier and retained for six months or less can be deleted by going to Settings > Siri & Search > Siri History and tapping “Delete Siri & Dictation History.”
You can control which apps can integrate with “Use with Siri” at any time at Settings > Siri & Search > [app name] > Use with Siri.
You may choose to turn off Location Services for Siri. To do so, open Settings > Privacy > Location Services > Siri & Dictation and select “Never”.
If you do not want Siri personalization to sync across your devices, you can disable Siri under iCloud settings.
You can also restrict the ability to use Siri & Dictation altogether under Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps > Siri & Dictation.
You can control which apps use Siri for transcription in Settings > Privacy > Speech Recognition.
