Privacy Policy

NotebookLM Organizer ("the extension") is a Chrome extension that adds folder and tag organization to Google NotebookLM. This page explains what data the extension handles and how.

Summary

• The extension does not operate any server. There is no backend collecting or receiving your data.
• All data the extension creates (folders, tags, and which notebooks they're assigned to) is stored using Chrome's built-in chrome.storage APIs, inside your own browser/Google account.
• The extension does not use analytics, does not track browsing activity, and does not sell or share data with any third party.

What data the extension stores

• Folders and tags you create, and which notebooks are assigned to them — stored via chrome.storage.sync, so this data syncs across devices where you're signed into the same Chrome/Google account, subject to Google's own Chrome Sync behavior and encryption.
• Notebook titles and URLs read from the NotebookLM page you're viewing, cached locally via chrome.storage.local so the side panel can display your notebook list without re-scanning the page every time.

None of this data is transmitted anywhere by the extension itself. It never leaves the storage APIs provided by Chrome.

What the extension does not do

• It does not send any data to a server operated by the developer — none exists.
• It does not collect analytics or usage statistics.
• It does not track your activity on any site other than notebooklm.google.com.
• It does not sell, rent, or share your data with third parties.
• It does not read or modify the content of your NotebookLM notebooks (sources, chat, notes) — only notebook titles and the tag/folder organization you create.

Permissions

The extension requests the minimum Chrome permissions needed for its features:

• storage — to save your folders, tags, and notebook organization as described above.
• sidePanel — to display the extension's UI as a Chrome side panel.
• tabs — to detect when you're on a NotebookLM tab (so the panel only appears there) and to open/navigate notebook links from the panel.
• Host permission for https://notebooklm.google.com/* — the extension's content script only runs on NotebookLM's own domain, to add tag/folder controls to notebook cards and read notebook titles. No other website is accessed.

Data deletion

Uninstalling the extension removes its locally cached data. Data stored via chrome.storage.sync is managed by Chrome Sync and can be cleared from your Google Account's Chrome Sync data, or by using the extension's own "Export/Import" and folder/tag deletion controls before uninstalling.
