## Privacy

Audio uploads directly from your browser to Heify's private bucket via a signed temporary URL — no third-party servers in between. No tracking, no analytics, no third-party scripts. The recent-recipients history lives only on your machine. API keys and Cognito tokens never appear in console output or diagnostics.

Full policy: [heify.com/en/privacy](https://heify.com/en/privacy).

***

## Requirements

Chrome 116+ (other Chromium browsers may work but aren't guaranteed), a [heify.com](https://heify.com) account, and an internet connection for the upload + report generation. The recording itself happens locally.

## FAQ

<AccordionGroup>
  <Accordion title="Does Heify record video?">
    No — only audio (system + microphone mix). Chrome's picker requires a "source" because of its API, but the video track is discarded immediately, except briefly to take screenshots when you request them.
  </Accordion>

  <Accordion title="Why does Chrome say I'm 'sharing my screen'?">
    Because technically you are — without screen-share, Chrome wouldn't let any extension capture system audio. The red bar comes from Chrome, not Heify.
  </Accordion>

  <Accordion title="Does it work with Zoom / Teams / Slack desktop apps?">
    Yes — pick **Window** in Chrome's picker and select the app. Remember to tick **Share audio**.
  </Accordion>

  <Accordion title="How long can a recording be?">
    Heify analyses up to **2 hours per recording**. On top of that, the browser holds the whole audio in memory until you stop — recordings longer than **\~1 hour can crash Chrome** on weaker machines. Split long sessions into shorter ones if you hit memory issues.
  </Accordion>

  <Accordion title="Can I recover a recording that was cut off?">
    If it lasted ≥3s and the source ended on its own (call finished, you closed Zoom), the send flow starts automatically. If Chrome crashed or you closed the Recorder window, the audio is lost.
  </Accordion>

  <Accordion title="Where do I see recorded meetings?">
    At [sandbox.heify.com](https://sandbox.heify.com) → Transcriptions.
