Facebook Video Downloader

Privacy Policy

Operated by TGvideodown.com · Last updated: August 25, 2026

This Privacy Policy describes how the Facebook Video Downloader browser extension ("Extension", "we", "us", or "our") collects, uses, and protects information when you install and use our Extension. By using the Extension, you agree to the practices described in this policy.

1. Overview

The Extension helps you download videos from Facebook pages you visit. It operates primarily on your device. We do not require you to create an account to use the Extension, and we do not collect your Facebook login credentials or password.

2. Information We Collect

2.1 Information Stored Locally on Your Device

The Extension uses Chrome's local storage to save:

  • Your preferred video download quality (e.g., 360p, 720p, 1080p)
  • Extension configuration and UI preferences
  • A randomly generated anonymous identifier (UUID) to distinguish installations
  • Extension installation time
  • Basic browser environment information (browser type, operating system platform, language, and user-agent string)
  • Review prompt display state (whether you have been shown a rating request)

This data remains on your device unless you uninstall the Extension or clear extension storage.

2.2 Usage Analytics

To improve the Extension's stability and features, we may collect anonymous usage analytics, including:

  • Extension version and installation time
  • Anonymous UUID (not linked to your real identity)
  • Browser type, language, and user-agent
  • Event types (e.g., install, update, feature usage)

Analytics data is transmitted to our log service provider (Alibaba Cloud Log Service) for processing. We do not use analytics to identify you personally.

2.3 Facebook Page Data (Processed Locally)

When you click download on a Facebook video, the Extension reads publicly available video information from the Facebook page you are viewing (such as video ID, page URL, and tokens present in the page context) solely to retrieve downloadable video links. This processing occurs in your browser to complete the download. We do not upload your Facebook content, messages, friends list, or profile data to our servers.

3. Permissions We Request

The Extension requests the following browser permissions for its core functionality:

  • tabs — To interact with Facebook tabs and open Facebook when you choose.
  • storage — To save your settings and preferences locally.
  • downloads — To save video files to your device.
  • offscreen — To process certain video formats locally before download.
  • Host access to facebook.com and fbcdn.net — To detect videos and fetch video files from Facebook's content delivery network.

4. How We Use Information

We use collected information only to:

  • Provide and maintain the download functionality
  • Remember your quality and display preferences
  • Diagnose errors and improve performance
  • Understand aggregate usage patterns to improve the Extension

5. Data Sharing and Third Parties

We do not sell, rent, or trade your personal information. We may share limited technical data with:

  • Facebook / Meta — When you download a video, your browser communicates directly with Facebook servers as necessary to retrieve the video file. This is governed by Facebook's own privacy policy.
  • Alibaba Cloud Log Service — For anonymous analytics and error logging, as described above.

We may also disclose information if required by law or to protect our legal rights.

6. Data Retention

Locally stored data persists until you uninstall the Extension or clear its storage. Analytics logs are retained for a limited period necessary for analysis and troubleshooting, after which they are deleted or anonymized.

7. Data Security

We take reasonable measures to protect information transmitted by the Extension. However, no method of transmission or storage over the Internet is 100% secure, and we cannot guarantee absolute security.

8. Your Choices

  • You can change your download quality preference in the Extension popup at any time.
  • You can uninstall the Extension at any time, which removes locally stored data associated with it.
  • You can disable or limit the Extension's access through your browser's extension management settings.

9. Children's Privacy

The Extension is not directed at children under the age of 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children.

10. International Users

The Extension may be used globally. Analytics data may be processed on servers located outside your country. By using the Extension, you consent to such processing as described in this policy.

11. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top will reflect the most recent revision. Continued use of the Extension after changes constitutes acceptance of the updated policy.
