Notebook (“we”, “us”, or “our”) is a Chrome Extension that allows users to create, edit, and manage notes directly in their browser.

This Privacy Policy explains how Notebook handles user information.

1. Information We Collect

Notebook does not collect or transmit your personal information.

The notes and other content you create using Notebook are stored locally in your Chrome browser using Chrome’s local storage.

We do not have access to the content of your notes.

2. How We Use Your Information

Notebook uses locally stored information only to provide its core functionality, including:

• Creating notes
• Editing notes
• Saving notes
• Deleting notes
• Managing notes within the extension

Your note content is not uploaded to our servers.

3. Data Storage

All notes created in Notebook are stored locally on your device through Chrome’s local storage.

Notebook does not maintain a remote database containing your notes.

If you uninstall Notebook, clear the extension’s storage, reset your Chrome profile, or otherwise remove the locally stored data, your notes may be permanently deleted.

4. Data Sharing

Notebook does not sell, rent, or share your notes or personal information with third parties.

Notebook does not use your notes for advertising, analytics, profiling, or other commercial purposes.

5. Third-Party Services

Notebook does not use third-party services to store or process your notes.

6. Chrome Permissions

Notebook uses Chrome’s storage functionality to save and manage your notes locally.

The extension requests only the permissions necessary for its functionality.

7. Data Security

Because your notes are stored locally in Chrome, the security of your notes also depends on the security of your device, Chrome browser, and operating system.

We do not transmit your notes over the internet.

8. Children’s Privacy

Notebook does not knowingly collect personal information from children.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time.

Any changes will be reflected on this page, and the “Last updated” date will be updated accordingly.
