Overview

TCG Sync Compare ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains how our Chrome extension handles information when you use it.

Single Purpose: This extension compares trading card prices across multiple sellers to help users find the best deals. It extracts product information from trading card websites and displays price comparisons from verified sellers in our database.

Chrome Extension Specific Information

Our Chrome extension (TCG Sync Compare) is designed with privacy-first principles:

  • No User Accounts: The extension works without requiring registration or login
  • No Personal Data Collection: We do not collect, store, or process any personal information
  • Minimal Permissions: Only requests activeTab and scripting permissions necessary for functionality
  • On-Demand Operation: Only activates when you click the extension icon
  • Transparent Operation: All code is packaged within the extension and reviewable

Information We Do NOT Collect

TCG Compare is designed with privacy in mind. We do NOT:

  • Collect any personal information (name, email, address, etc.)
  • Track your browsing history
  • Store any data about the cards you view
  • Use cookies or tracking pixels
  • Share any information with third parties
  • Collect analytics or usage statistics
  • Access your bookmarks, downloads, or other browser data

How the Extension Works

TCG Compare operates entirely locally in your browser:

  • Page Analysis: When you click the extension icon, it reads the product information from the current webpage you're viewing.
  • API Requests: The extension may make requests to our API server ONLY to match card information and retrieve price comparisons.
  • No Storage: No information is stored locally or remotely after you close the extension popup.
  • No Background Activity: The extension only runs when you actively click on it.

Permissions Explained

The extension requires minimal permissions:

  • activeTab: Allows the extension to read product information from the current tab when you click the extension icon.
  • scripting: Enables the extension to extract product details from the webpage.

These permissions are only used when you actively click the extension icon and are never used for tracking or data collection.

API Communication

When you use the extension, it may communicate with our API server (extension.tcgsync.com) to:

  • Match card details to our product database
  • Retrieve current price information from various sellers

These API calls:

  • Only send the card information visible on the current page
  • Do not include any personal information
  • Are not logged or associated with any user identifier
  • Use HTTPS encryption for all communications

Data Security

We implement appropriate technical measures to ensure data security:

  • All API communications use HTTPS encryption
  • No user data is stored on our servers
  • The extension code is open to review in the Chrome Web Store

Third-Party Services

TCG Compare does not integrate with or send data to any third-party services, analytics platforms, or advertising networks.

Children's Privacy

TCG Compare does not knowingly collect any information from anyone, including children under 13 years of age, as we do not collect any personal information at all.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. Continued use of the extension after changes constitutes acceptance of the updated policy.

Open Source

We believe in transparency. The extension's functionality can be reviewed through the Chrome Web Store's inspection tools.
