# Apple explains how Siri Recap handles conversations it hears

**Apple explains how Siri Recap handles conversations it hears**, from Secure Exclave processing and Private Cloud Compute summaries to speaker attribution limits and seven‑day auto‑deletion.

# Apple explains how Siri Recap handles conversations it hears

**Apple explains how Siri Recap handles conversations it hears** in a new support article and privacy documentation released alongside the Apple Watch Series 12 and Ultra 4 launch. The company details how ambient audio is captured, processed, summarised, and deleted, and what information is intentionally excluded from the AI‑generated notes.

Siri Recap is part of Apple’s new **Audio Intelligence** features, which use Apple Intelligence to listen to conversations throughout the day and create high‑level summaries designed to “jog your memory” so you can stay present in the moment. Apple stresses that the feature does not create or store conventional audio recordings.

## How audio is captured and isolated

When Siri Recap is enabled, the Apple Watch uses its microphones to detect when speech is occurring. A dedicated on‑device model determines that a conversation is taking place without recording or transcribing anything at that stage.

Once speech is detected:

- Audio flows into a protected buffer inside the **Secure Exclave** on the Apple Watch’s **S11 chip**.
- The Secure Exclave is a hardware‑isolated compartment that the operating system, apps, the user, and even Apple cannot access.
- The encrypted audio is transmitted over a secure Bluetooth link to the **Secure Exclave on the paired iPhone**.
- The raw audio is **immediately deleted from the Apple Watch** after transfer.

On the iPhone, the audio is decrypted, transcribed, and condensed inside the iPhone’s Secure Exclave. The raw audio is then deleted from the iPhone as well.

## From transcript to summary: Private Cloud Compute

Siri Recap does not produce a full, word‑for‑word transcript. Instead, it creates a shortened, distilled version of the conversation that focuses on core meaning. Apple says this condensed text is **less than half the length** of the original transcript and removes:

- Tone and non‑essential language.
- Filler words and redundancies.
- Repeated phrases and tangents.

This condensed, encrypted text is then sent to **Private Cloud Compute (PCC)**, where **Apple Foundation Models** generate the final summary. Apple states that data processed in PCC is not accessible to Apple or anyone else.

The output appears in the **Siri app** on iPhone and Apple Watch as:

- A title for the conversation.
- A high‑level summary.
- Key points and action items.

## What Siri Recap does not do

Apple has built several privacy and safety constraints into Siri Recap:

**No speaker attribution:** Siri Recap will not identify or attribute statements to specific speakers. Names may appear if mentioned in the conversation, but nothing is linked to a particular person.

**Sensitive data filtering:** Summaries are designed to omit potentially harmful content (such as language promoting self‑harm or hate speech) and sensitive information, including:

-  Financial data.
-  Government‑issued identifiers.
-  Authentication data (passwords, codes).
-  Certain personal identifiers.

**No stored audio:** Apple emphasises that no audio recordings are created or stored. Only text snippets and summaries exist, and these are end‑to‑end encrypted when synced via iCloud.

Apple also warns that summaries can be **incomplete or inaccurate** and that filtering may not catch all sensitive information.

## Retention and deletion

By default, Siri Recap summaries are **automatically deleted after seven days** unless the user explicitly saves or exports them. Saved summaries and Live Rewind text snippets remain end‑to‑end encrypted in the Siri app with iCloud syncing, and are not accessible even to Apple.

Users can also:

- Turn Siri Recap off entirely.
- Set schedules for when it is allowed to listen.
- Review and delete individual recaps in the Siri app

## Why Apple is explaining this now

The detailed explanation comes amid public concern about an “always‑listening” watch. By documenting the flow of data from the Secure Exclave on the watch, to the Secure Exclave on the iPhone, to Private Cloud Compute—and back to an encrypted summary in the Siri app—Apple is attempting to normalise always‑on AI while emphasising that:

- No raw audio is accessible to anyone.
- No conventional recordings are made.
- Summaries are short, filtered, and temporary by default.

**Summary:** **Apple explains how Siri Recap handles conversations it hears** by routing encrypted audio through the Secure Exclave on Apple Watch and iPhone, sending only a condensed transcript to Private Cloud Compute for summarisation, omitting sensitive data and speaker attribution, and auto‑deleting summaries after seven days unless saved.
