Murmur / Privacy
Murmur privacy policy
Murmur turns your voice into text on your own computer. Nothing you say or type is sent to me or to anyone else.
What Murmur is
Murmur is a free voice-typing app for Windows that lives in the system tray. You hold a hotkey, speak, and the words are typed into whatever app you are using. Speech is recognised on your computer with OpenAI’s open-source Whisper model.
What is collected
Murmur collects and transmits nothing about you.
- No accounts or sign-in
- No analytics, telemetry, advertising identifiers or crash reports
- No online services: your audio and your text are never uploaded
Your microphone
Murmur records from your microphone only while you hold its hotkey, or between the two taps of hands-free mode. The recording is turned into text on your computer and then discarded. If you switch on Keep audio recordings in Settings (it is off by default), each recording is saved on your computer next to its dictation, and nowhere else.
Your keyboard and clipboard
- Murmur watches the keyboard only to notice the hotkey you chose, and Esc to cancel a dictation. It does not record, store or send what you type.
- To insert text, Murmur puts the dictated text on the clipboard for a moment, pastes it, and then puts back what you had copied before. These clipboard writes are marked so they stay out of Windows clipboard history and cloud clipboard.
Data stored on your computer
Murmur keeps the following on your computer only, in its folder under your user profile’s local app data:
- Your settings and your vocabulary (hint words and replacement rules)
- Your dictation history: the text, the time, and the name of the app it was typed into. You can delete single entries or clear it all from the History page
- Audio recordings, only if you switched them on
- Log files with timings and errors. They never contain what you said
- The speech model
Uninstalling Murmur removes this data.
The one network request
The first time Murmur starts, it downloads its speech model (about 1.6 GB) from Hugging Face. Like any download, that request shows your IP address to Hugging Face; it carries no audio, text or personal information. See Hugging Face’s privacy policy. After that, Murmur works without an internet connection.
Children
Murmur is not directed at children and does not knowingly collect information from anyone.
Changes
If Murmur ever starts handling data differently, this page will be updated before that version is released, and the date above will change.
