Your recording is deleted right after scoring — no audio kept. What happens to my voice?
Your recording is analyzed on the server and deleted immediately after scoring, on success or failure — no audio is stored. What you say is sent to Anthropic (the tutor) and, if your browser can't transcribe locally, to OpenAI Whisper. Your pitch range is kept anonymously (a cookie in this browser, no account) purely to calibrate scoring to your voice. A practice tool, not a service for children.
