Privacy policy

Last updated: March 2026

1. Introduction

Futabits ("we", "our", or "us") develops Key Mode, a Chrome extension for keyboard-driven tab and tab group management. This Privacy Policy explains how we handle your information when you use the extension.

Key Mode is designed with privacy as a core principle. The extension operates entirely within your browser and does not collect, transmit, or store any personal data.

2. Information we collect

Key Mode does not collect any personal information. Specifically:

  • No analytics: We do not use any analytics services or tracking.
  • No telemetry: The extension does not send usage data, crash reports, or any other telemetry.
  • No account required: Key Mode does not require sign-up, login, or any personal information to function.

3. Chrome permissions

Key Mode requests the following Chrome permissions to function. These permissions are used exclusively within your browser and no data is transmitted externally:

  • tabs: Required to list, navigate, and manage your browser tabs.
  • tabGroups: Required to create, modify, and navigate tab groups.
  • activeTab: Required to identify and interact with the currently active tab.
  • scripting: Required for the content search feature, which searches text on your open pages.
  • storage: Required to save your extension preferences locally in Chrome's storage.
  • windows: Required to move tabs and groups between browser windows.

4. Optional host permissions

Key Mode may request optional host permissions (<all_urls>) to enable the content search feature. This permission allows the extension to read page content for search purposes only. This permission is:

  • Optional: The extension works without it. Content search is the only feature that requires it.
  • Revocable: You can revoke this permission at any time from within the extension.
  • Local only: Page content is searched within your browser and is never transmitted anywhere.

5. Local storage

Key Mode uses Chrome's local storage API to save your preferences (such as settings). This data is stored locally on your device within Chrome and is never transmitted to any external server.

6. Third-party services

Key Mode does not integrate with, send data to, or receive data from any third-party services. The extension operates entirely offline within your browser.

7. Data retention

Since Key Mode does not collect any data, there is no data to retain. Your local preferences are removed when you uninstall the extension.

8. Children's privacy

Key Mode does not collect personal information from anyone, including children under the age of 13.

9. Changes to this policy

We may update this Privacy Policy from time to time. We will notify you of any significant changes by posting the new policy on this page and updating the "Last updated" date.
