What we do with your voice.

When you hold the dictation hotkey, your microphone records into a temporary file on your device. That file is sent over HTTPS to the Buna cloud transcription service, which runs Google Gemini through Firebase AI/Vertex. Once a transcript comes back, the audio is deleted from the proxy and from your device. We do not store audio.

Long recordings (over 2 MB) are uploaded to your private path in Buna's Cloud Storage bucket so we can stream them to the model. They are deleted automatically as soon as transcription succeeds.

Each successful dictation creates a row in your private history collection (signed-in users only). You can delete any row from History. Transcripts sync across your signed-in devices and are stored in Google Firestore in the United States.

The Mac beta uses Google sign-in through Firebase Auth. We store your Firebase user identifier, display name if available, and email. We do not see your Google password.

We count seconds of audio you transcribe each month, so we can enforce the 60 minute/month free beta quota. The counter lives in your Firestore document — it's a number per month, nothing else.

None by default. We don't embed Google Analytics, Mixpanel, Amplitude, or any other product analytics SDK. If you opt into crash reporting, only the stack trace and OS version are sent — personally-identifying data is stripped.

We do not train on your audio or your transcripts. Buna uses Google Cloud's Vertex AI/Firebase AI path for transcription; your dictations are not used to train Buna-owned models.

Email hello@bunavoice.com from the address tied to your Buna account and we'll delete every row associated with your account within 7 days. You can also delete transcripts one at a time from the History view.

Anything else, just ask: hello@bunavoice.com.
