TubeNotes is a Chrome extension for capturing YouTube transcripts and metadata locally while maintaining user privacy.
The extension does not collect, store, share, or transmit personal data including viewing history, video titles, transcripts, or browsing activity. Users don't need accounts, and all data extraction happens entirely within your browser on your local device.
TubeNotes uses two services for anonymous telemetry to understand usage and detect bugs. No YouTube URLs, video titles, transcript content, or any personally identifiable information is ever included.
On error, the following is sent to Sentry:
- Error description
- Extension version
- Chrome version
Sentry privacy policy: https://sentry.io/privacy/
On key actions (opening the extension, successful extraction, errors, review prompt interactions), the following is sent to PostHog:
- Event name (e.g. "popup_opened", "extraction_success")
- A randomly generated anonymous device ID (stored locally, never linked to any identity)
- Transcript line count (on successful extraction)
- Extension version
- Chrome version
