Recordings are stored in memory only — never uploaded. They are lost when you close or reload the page.
Titles and transcript text are saved in your browser's localStorage — on your device only, never sent anywhere.
Murmur is fully client-side. No sign-ups, no analytics, no cookies, no third-party scripts — except for the transcription service below.
This page uses the Web Speech API, which routes your voice through Google's servers in Chrome and Edge. Google's Privacy Policy applies. Avoid sensitive information if this is a concern.
