Privacy Policy for Warp to Sub-Screen

Last Updated: 2025-9-9

This Privacy Policy describes how the “Warp to Sub-Screen” Chrome extension (the “Extension”) handles your information. Your privacy is important to us, and we are committed to protecting it.

1. Information We Do Not Collect

We do not collect, store, use, or share any of your personal information. The Extension is designed to work entirely on your local machine.

• No Personal Data: We do not collect any personally identifiable information, such as your name, email address, or IP address.
• No Browsing History: We do not track your browsing history, the websites you visit, or your search queries.
• No Usage Analytics: We do not use any analytics or tracking services to monitor how you use the Extension.

2. Permissions and Their Usage

The Extension requires certain permissions to function. This section explains why each permission is necessary.

• system.display (Access display information):
  • Purpose: To get information about your connected monitors.
  • Usage: This permission is used solely to identify your primary and sub-monitors. The Extension needs this information to move the browser window to the correct screen. This data is used only when you activate the Extension and is not stored or transmitted.
• scripting (Run scripts on the current tab):
  • Purpose: To inject a content script (content.js) into the active tab.
  • Usage: This permission is used to find a video player element (like a <video> tag) on the webpage and trigger its fullscreen mode. This script only runs when you click the Extension icon and only performs this specific action.
• host_permissions: ["<all_urls>"] (Access to all websites):
  • Purpose: To allow the Extension to work on any website.
  • Usage: This permission is necessary so that you can move a tab to your sub-screen regardless of the website you are on. The Extension does not read the content of any website for any other purpose.

3. Data Security

Since we do not collect or store any of your data, there is no risk of your data being lost, stolen, or misused by us. All operations performed by the Extension are confined to your browser on your computer.

4. Changes to This Privacy Policy

We may update this Privacy Policy in the future if the Extension’s functionality changes. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last Updated” date.

5. Contact Us

If you have any questions about this Privacy Policy, please contact us.
