Open the original- What it measures
- Microsoft's data-handling statement for Copilot Voice under personal accounts. The other conversation history is kept for 18 months by default, according to Microsoft's Copilot privacy FAQ.
- What it does not show
- The statement does not give a period for voice transcripts itself, so the 18-month default is the period of the other history, not a figure Microsoft states for voice. The personal-account text also says voice data is used to provide the Copilot Voice experience.
