MicDucker is a local audio utility. It does not intentionally send microphone audio, speaker data, voiceprint data, or usage telemetry to any remote service.

The optional voiceprint gate stores a numeric feature vector at:

~/.config/mic-ducker/voiceprint.json

Raw enrollment audio is not saved by the enrollment command. Delete the voiceprint file to remove local enrollment data.

Please do not include private recordings, voiceprint files, or other sensitive audio artifacts in public issues. Describe the behavior, your command-line arguments, and relevant logs instead.

If you believe you found a security or privacy issue, open a GitHub issue with a minimal description and avoid attaching sensitive files.
