Privacy Policy
What data the extension accesses and how it is used.
Summary
- The extension operates locally in your browser
- No data is sent to third-party servers by the extension
- All API calls go directly to NotebookLM (Google)
- Authentication tokens are stored locally in your browser
- This website uses Google Analytics for basic page view statistics
Extension permissions explained
The extension requires the following permissions, as declared in the manifest.json file:
| Permission | Purpose |
|---|---|
activeTab | Read the URL of the current tab when you click the extension icon, so it can be imported to NotebookLM. |
storage | Store the authentication token locally so you don't have to re-authenticate on every use. |
scripting | Inject a content script into NotebookLM pages to extract the authentication token needed for API calls. |
tabs | Query open browser tabs (for the "import open tabs" feature) and open new tabs (e.g., to open NotebookLM when needed). |
downloads | Download audio overview files to your computer. |
Host permissions explained
| Permission | Purpose |
|---|---|
https://notebooklm.google.com/* | Required to interact with NotebookLM. The extension injects a content script and makes API calls to this domain. |
<all_urls> | Required to fetch external URLs (RSS feeds, YouTube playlists) from the background script, bypassing CORS restrictions. |
About <all_urls>: This broad permission is needed because RSS feeds and YouTube playlists can be hosted on any domain. The extension only fetches URLs when you explicitly parse a playlist or RSS feed.
TODO: Evaluate if this permission can be narrowed in future versions.
Data handling
What is stored locally
- Authentication token: A session token from NotebookLM, stored in
chrome.storage.local. This is used to authenticate API requests.
What is NOT stored
- Your notebook contents
- URLs you import
- Browsing history
- Any personal information
Where data is sent
All API requests go directly to notebooklm.google.com. No data is sent to any other server by the extension.
Website analytics
This website (not the extension) uses Google Analytics 4 with Measurement ID G-KG04RK8E33.
What is tracked
- Page views (which pages are visited)
- Basic session information (duration, bounce rate)
- General geographic region (country level)
- Browser and device type
What is NOT tracked
- Personal identity
- Extension usage data
- NotebookLM content or activity
- Advertising or remarketing data
Website analytics are only for understanding site traffic. No custom events are implemented.
TODO: Clarify Google Analytics data retention policy and IP anonymization settings.
Third-party services
Google NotebookLM
The extension communicates with Google's NotebookLM service. Google's privacy policies apply to how NotebookLM handles your data. See Google Privacy Policy.
External content sources
When you parse RSS feeds or YouTube playlists, the extension fetches those URLs directly. The extension does not collect or store the content; it only extracts links to pass to NotebookLM.
Changes to this policy
If this privacy policy changes, updates will be posted on this page and noted in the changelog.
