About Spotlight Suggestions
Siri analyzes how you use your device to provide personalized suggestions and better search
Siri learns how you use your devices in order to personalize your experience. Using information stored on your device, such as your Safari browsing history, emails, messages, and contacts, as well as information contributed by other installed apps, Siri can provide suggestions in Spotlight, Look Up, Photos Memories, and more. You can see the full list of features that Siri personalizes in the Siri section of System Preferences, under Siri Suggestions & Privacy.
Personalization is synced across your devices with end-to-end encryption
Siri securely syncs this information among your devices, to make your experience consistent on all of them. This sync is done using end-to-end encryption.
To make suggestions and search results more relevant, some information is sent to Apple and not associated with you
In some cases, such as when you use Siri Suggestions in Spotlight, Look Up, or Safari, generalized topics of interest that Siri has learned may be sent to Apple to make your searches more relevant. These topics of interest (for example, cooking or basketball) will help to give you more relevant search results, and we use privacy-friendly techniques to disassociate these topics of interest from you.
In addition to these topics of interest, when you perform a search, your device sends your search queries, suggestions you have selected, and related usage data to Apple to process your request. This information is not associated with you. Search results that show files and content on your device will not be sent.
If you have Location Services on your device turned on, the location of your device will be sent to Apple to provide more relevant recommendations. Searches for common words and phrases may be forwarded from Apple to a search engine. These searches are not stored by the search engine provider. To provide you with more relevant music and video suggestions, if your device can access music or video subscription services, then information such as the names of the subscription services and types of subscriptions may be sent to Apple. Your account name, number and password will not be sent to Apple. Location, search queries, your interests, and usage information sent to Apple will only be used by Apple to make Suggestions more relevant and to improve other Apple products and services.
You have choice and control
You can stop apps from contributing information to personalize Siri. Go to System Preferences, click Siri, then select Siri Suggestions & Privacy. Deselect the checkbox for an App.
If you do not want Siri Suggestions to send your information to Apple, you can turn off Siri Suggestions.
