Privacy Policy

Last updated on January 16, 2026.

NotebookLM Tools ("Extension," "we," "us," or "our") is a Chrome browser extension that enhances your experience with Google's NotebookLM service. We are committed to protecting your privacy. This Privacy Policy describes how we handle information when you use our Extension.

Information We Collect

NotebookLM Tools does not collect or store your personal data on our servers.

The Extension may store the following data locally in your browser:

  • Your extension preferences and settings
  • Custom tags you create for organizing notebooks
  • Language preferences for the NotebookLM interface
  • Playlist and playback progress for audio guides

All of this data is stored locally using Chrome's storage APIs and is never sent to our servers or any third parties.

How We Use Information

The locally stored data is used solely to provide the Extension's functionality, such as:

  • Remembering your tag configurations and color preferences
  • Maintaining your language settings across sessions
  • Tracking your audio playback progress
  • Storing your extension preferences

Data Sharing

We do not share, sell, or transmit your data to any third parties. Your notebooks, sources, and all content remain with Google's NotebookLM service. NotebookLM Tools only reads and interacts with this data locally in your browser to provide its features.

Third-Party Services

NotebookLM Tools interacts with Google's NotebookLM service (notebooklm.google.com). Your use of NotebookLM is governed by Google's Privacy Policy. We do not control and are not responsible for Google's data practices.

Sponsored Content

The Extension may display sponsored content and links to third-party services. When you click on these links, they may include tracking parameters to measure engagement. NotebookLM Tools does not collect this data, but the destination websites may collect information according to their own privacy policies.

Data Security

Since all Extension data is stored locally in your browser using Chrome's built-in storage mechanisms, your data benefits from Chrome's security protections. No data is transmitted over the internet to our servers.

Your Choices

You have full control over your Extension data:

  • You can clear all Extension data by uninstalling the Extension
  • You can reset specific settings through the Extension's options
  • You can use Chrome's developer tools to view and manage stored data

Children's Privacy

NotebookLM Tools is not directed at children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the Extension after any changes indicates acceptance of the updated policy.
