The phone says when.

Inside an ordinary SA‑NT call, the owner can ask to start a phone capture. SA‑NT first explains that it will keep a transcript for seven days and asks for confirmation. The call controller—not a model-written reply—then speaks the room notice before the next passage can be retained.

The notice says what is happening and that anyone present can ask SA‑NT to pause, stop or delete the capture. A dropped call stops its capture rather than leaving it open for a later conversation.

During capture, SA‑NT keeps completed speech-to-text passages and stays quiet. Those passages do not enter the assistant turn, so something said in the room cannot accidentally send mail, change a calendar or invoke another tool.

Pause stops retention immediately. Resume is announced aloud. Stop closes the session, and delete removes the transcript. The private review page shows the retained passages and the recorded consent and notice state.

Phone capture stores a transcript, not audio. It does not claim the dedicated instrument's visible light, physical privacy control or encrypted-media path. It adds no new account integration or provider permission.

This flow is available in the private pilot. Speakerphone comprehension, noisy-room commands and jurisdiction-specific use still require live verification. An audible notice is not a universal legal conclusion; recording rules vary by country, workplace, client and setting.
