Privacy Policy for Tab Blocks

Last Updated: May 2, 2025

This Privacy Policy describes how the "Tab Blocks" Firefox extension handles your information.

1. Data Storage:

• Local Storage: All your created collections and saved links (including their URLs, titles, favicon URLs, and collapsed state) are stored only locally on your computer using the browser's standard browser.storage.local API.
• No External Transmission: This data is not sent to any external servers or third parties. It remains entirely within your browser's local storage for the extension.

2. Permissions Used:

• tabs Permission: This permission is used solely to:
  • List your currently open tabs in the sidebar.
  • Retrieve the title, URL, and favicon URL when you drag a tab to save it as a link block.
  • This information about open tabs is not stored by the extension, except for the specific details you choose to save by dragging a tab into a collection.
• storage Permission: This permission is required to save your collections and links locally on your device so they persist between browser sessions.
• downloads Permission: This permission is used only when you explicitly click the "Export" button to save your configuration file to your computer. The extension does not initiate downloads otherwise.

3. Data You Provide:

• Collections and Links: You create collection names and link titles. You add links by dragging tabs. This information is stored locally as described above.
• Imported Data: When you use the "Import" feature, the extension reads the selected JSON file (either native format or Toby format) to populate your collections. This data is then stored locally.

4. Data Usage:

The data stored locally is used exclusively to provide the core functionality of the Tab Blocks extension: displaying your collections and links on the new tab page, allowing you to organize them, and enabling the import/export features.

5. Data Security:

While the data is stored locally, standard browser security measures apply. However, be aware that anyone with access to your browser profile could potentially access the extension's local storage.

6. Changes to This Policy:

This Privacy Policy may be updated from time to time. Any changes will be reflected in the updated version of the extension.
