## Data Collection

NoteFlow **does not collect, upload, or share any user data**. All operations run entirely in your local browser.

## Data Storage

The following data is stored in Chrome's local storage (`chrome.storage.local`) and is only used while the extension is running:

* **Import History**: URLs, titles, import timestamps, success/failure status
* **Settings**: Language preference, auto-rename, and other preferences
* **Notebook Cache**: Notebook titles and IDs (for Target Notebook selection)

This data stays on your local machine and is automatically cleared when you uninstall the extension.

## Network Requests

NoteFlow only makes the following network requests:

* **NotebookLM**: Sends user-selected URLs to `notebooklm.google.com` to create sources
* **Bilibili API**: Queries video info and subtitle data
* **YouTube API**: Fetches video listings and metadata
* **Apple Podcasts / Xiaoyuzhou**: Fetches podcast info
* **Chrome Web Store**: Checks for extension updates

All requests use HTTPS encryption.

## Third-party Services

NoteFlow integrates with:

* **Supabase**: Optional user authentication
* **Google OAuth**: Multi-account switching
