# Siri AI personalization and opt-in improvement data lifecycle > Source-anchored research for Siri AI personalization and opt-in improvement data lifecycle. Run status: COMPLETED. Parent: [Apple Intelligence](https://llms-explorer.com/tree/apple-intelligence/) · 3 facets · 17 facts · page: https://llms-explorer.com/tree/siri-ai-personalization-and-opt-in-improvement-data-lifecycle/ ## Definitions - Availability is not uniformly described in the sources reviewed: Apple Support’s page published October 22, 2026 still labels Siri AI as beta and says setup places the user on a waitlist, while 9to5Mac reported a public release on September 14. The current Apple support description does not establish general availability across devices, regions, and accounts. (medium confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) ## How it works - Apple Support says the dedicated Siri app syncs conversation history across Apple devices with iCloud. Apple’s improvement disclosure includes conversations saved in the Siri app and says it collects follow-up requests and Siri responses when a user continues a conversation. Thus PCC’s request-processing statement does not establish that Siri app history or opted-in copies are ephemeral; Apple’s current Siri AI support page does not explicitly say that this history is end-to-end encrypted. (high confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) - When a user opts in, Apple says it may store Siri and Dictation interactions including audio, spoken or typed transcripts, responses, and related request data such as request category, device specifications, performance statistics, and approximate location. Apple says it does not collect photos or attachments provided to Siri, notification content, or the information Siri searches on-device, and that it takes steps to remove personal details and some source content from responses. The disclosure therefore distinguishes the request and response record from the underlying personal material Siri used. (high confidence) (verified as of 2026-10-23) — [source](https://www.apple.com/legal/privacy/data/en/improve-intelligence/) - Apple says opted-in audio, transcripts, and related request data use a random device-generated identifier that rotates multiple times per hour and is not tied to an Apple Account or email address. Apple also says it may connect multiple rotating identifiers when a user resumes a conversation. Opted-in data may be retained and used for up to two years; the small reviewed subset may be kept longer. The rotating identifier therefore does not mean that follow-ups within a conversation are kept unlinked. (high confidence) (verified as of 2026-10-23) — [source](https://www.apple.com/legal/privacy/data/en/improve-intelligence/) - Apple’s general Siri and Dictation disclosures say audio is not stored by default, but transcripts and related request data may be retained for up to two years and computer-generated transcripts are used to improve Siri and Dictation by default. Apple separately says foundation-model training uses private personal data or interactions only when a user explicitly chooses to help improve the models. Turning off the opt-in therefore does not mean that no Siri transcripts are retained or used for product improvement. (high confidence) (verified as of 2026-10-23) — [source](https://www.apple.com/legal/privacy/data/en/ask-siri-dictation/) - Report a Concern is a separate, user-initiated feedback flow. Apple says it may use submitted reports to improve products and train models; a report can include user-provided descriptions, photos, videos, messages, or emails plus device and model metadata. Users can review and remove information or attachments before submitting. The cited support article does not give a retention period for these reports. (low confidence) (verified as of 2026-09-15) — [source](https://support.apple.com/en-euro/121503) ## Facts and statements - Apple describes Siri AI as processing requests on-device or with Private Cloud Compute (PCC); its privacy page says on-device processing can use personal data without collecting it and that data processed in PCC is not stored. EFF says some on-screen requests may send context to PCC and the interface does not immediately show which route a request took. These statements concern request processing, not persistence of Siri app history or separate opted-in improvement data. (high confidence) (verified as of 2026-10-23) — [source](https://www.apple.com/privacy/features/) - Apple’s support guide describes Improve Siri & Apple Intelligence as an optional setting for Siri AI, adjustable at Settings > Privacy & Security > Analytics & Improvements on iPhone and iPad. Apple says the preference is presented during setup and can be changed later; enabling it permits storage and review of sample audio and transcripts and allows use of the data to train foundation models. 9to5Mac reported that Siri AI setup presented “Share Audio and Text” and “Not Now.” (high confidence) (verified as of 2026-10-23) — [source](https://support.apple.com/en-ae/127070) - Apple documents Report a Concern as a separate, user-initiated feedback path: a user can review and remove submitted information or attachments, and Apple says it may use the report to improve products and train models. The report can include text, photos, videos, messages, emails, device details, and model-version information. Apple’s pages do not say whether disabling Improve Siri & Apple Intelligence changes how Apple handles a separately submitted report. (medium confidence) (verified as of 2026-09-15) — [source](https://support.apple.com/en-euro/121503) - Apple distinguishes Siri AI request processing from optional improvement-data collection. Apple says Apple Intelligence can use personal data on device without collecting it, and requests processed through Private Cloud Compute (PCC) are used only to fulfill the request and are not retained by PCC. The separate Improve Siri & Apple Intelligence setting is an opt-in path for collecting interactions to improve services and train foundation models. (high confidence) (verified as of 2026-10-23) — [source](https://www.apple.com/privacy/features/) - Apple says Siri AI’s personal-context feature can find information across Messages, Mail, Calendar, Notes, Reminders, and more. Apple describes on-device Apple Intelligence as using personal data without collecting it. EFF’s September 18, 2026 analysis notes that some requests may use PCC and that users receive no immediate visual indication whether a specific request was processed locally or in the cloud. (medium confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) - Apple’s October 22, 2026 support article says the dedicated Siri app syncs conversation history across Apple devices through iCloud. Separately, Apple’s improvement notice includes conversations in the Siri app in the optional contribution program. These notices do not specify how long synced chat history persists or whether deleting that history also deletes any copy included in an opted-in improvement contribution. (medium confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) - If a user enables Siri AI and opts in to Improve Siri & Apple Intelligence, Apple’s legal notice says it may store all Siri and Dictation interactions, including audio and transcripts of spoken or typed requests, Siri’s responses, and follow-up conversation. Apple may also collect Translate interactions and related request data such as request category, device specifications, performance statistics, and approximate device location. Apple says these data can improve Siri and related language-processing features and train its foundation models. (high confidence) (verified as of 2026-09-16) — [source](https://www.apple.com/legal/privacy/data/en/improve-intelligence/) - Apple associates opted-in Siri audio, transcripts, and related request data with a random device-generated identifier that rotates multiple times per hour and is not tied to an Apple Account or email address. Apple may connect multiple identifiers associated with a conversation if the user re-engages with that conversation. (high confidence) (verified as of 2026-09-14) — [source](https://www.apple.com/legal/privacy/data/en/improve-intelligence/) - Apple’s specific Siri AI privacy notice says opted-in improvement data may be retained and used for up to two years, and a small subset of interactions reviewed may be kept longer. Apple says a subset may be reviewed by graders, only Apple employees can access Siri audio, and reviewers may access context directly relevant to grading. Apple also says it excludes photos or attachments provided to Siri, notification content, and information Siri searches on device, while taking steps to remove personal details from response content. (high confidence) (verified as of 2026-09-16) — [source](https://www.apple.com/legal/privacy/data/en/improve-intelligence/) - Inferred from Apple’s separate notices: opting out of Improve Siri & Apple Intelligence does not by itself disable all Siri and Dictation processing or local personalization. Apple’s Siri and Dictation notice says audio is not stored unless a user opts in to the older Improve Siri & Dictation setting, while transcripts and related request data may still be stored and used to improve Siri. It also says interaction history is stored on device for personalization and that disabling Siri and Dictation deletes those local transcripts. (medium confidence) (verified as of 2026-09-18) — [source](https://www.apple.com/legal/privacy/data/en/ask-siri-dictation/) - Apple says users can change Improve Siri & Apple Intelligence at any time in Settings > Privacy & Security > Analytics & Improvements. Its support guide distinguishes this setting for Siri AI users from the older Improve Siri & Dictation setting available to others, and says setup preferences can carry to newly configured Apple devices with Siri enabled.
