Siri and Dictation
The longer you use Siri and Dictation, the better they understand you and improve. To help them recognise your pronunciation and provide better responses, certain information such as your name, contacts, music you listen to and searches is sent to Apple servers using encrypted protocols. Siri and Dictation do not associate this information with your Apple ID, but rather with your device through a random identifier. Apple Watch uses the Siri identifier from your iPhone. You can reset that identifier at any time by turning Siri and Dictation off and back on, effectively restarting your relationship with Siri and Dictation. When you turn Siri and Dictation off, Apple will delete the User Data associated with your Siri identifier and the learning process will start all over again.
We try to keep all your information on your device where it makes the most sense and give you options to control how it’s shared. For example, when you use Siri to search for a photo by location or album name, we don’t have to send the photo to a server to get an answer. Album names are sent to Siri, but only to help provide you with better results. QuickType keyboard features are made possible by an Apple-developed neural network language process that runs directly on your device. Apps can use Siri to respond to your requests or send audio to Apple to transcribe to text — but only if you give your permission first.
If you have Location Services turned on, the location of your device at the time you make a request will be sent to Apple to help Siri improve the accuracy of its response to your requests. You can choose to turn off Location Services for Siri and Dictation in your Privacy settings.
You can also receive helpful suggestions before you even ask, based on the things you use often and when you typically use them. These predictions are kept on your device, not in the cloud, so the information is protected by all the safeguards that are built in.
Certain features do require real-time input from Apple servers. For example, event addresses and a user’s location are sent to Apple so that we can provide accurate Time to Leave predictions that take traffic into consideration. Information like a user’s location may be sent to Apple to provide localised suggestions as well as relevant news and search results. When we do send information to a server, we protect your privacy by using anonymised rotating identifiers so that searches and locations can’t be traced to you personally. And you can disable Location Services, our proactive features or the proactive features’ use of your location at any time.
Siri for macOS is built with the same privacy features as Siri for iOS.
