Privacy Policy for Utility Man Chrome Extension

Last Updated: July 12, 2025
Extension Version: 1.1.0

Overview

Utility Man is a Chrome extension that provides solutions for Immaculate Grid puzzles by querying Sean Lahman's baseball database. This privacy policy explains how we handle data in accordance with Chrome Web Store policies and user privacy expectations.

Data Collection and Handling

What Information We Collect

Utility Man does NOT collect, store, or transmit any personal or sensitive user data.

Specifically, our extension:

• Does NOT collect personally identifiable information (names, addresses, emails, phone numbers)
• Does NOT collect financial or payment information
• Does NOT collect authentication information (logins, passwords, cookies)
• Does NOT collect web browsing activity or history
• Does NOT collect website content beyond what is necessary for functionality
• Does NOT collect form data or personal communications
• Does NOT collect user-generated content

What Information We Do Access

The extension only accesses:

1. Grid Cell Labels: The extension reads aria-label attributes from grid cells on immaculategrid.com to determine which baseball statistics are being requested (e.g., "Yankees + Home Runs"). This information is:
   • Used solely to query our baseball database API
   • Not stored permanently
   • Not transmitted to any third parties
   • Processed only on pages matching "https://www.immaculategrid.com/*"
2. User Preferences: The extension stores your visibility preference (hide/show solutions by default) locally in your browser using Chrome's storage API. This data:
   • Never leaves your device
   • Is not transmitted to any servers
   • Can be cleared by uninstalling the extension

How We Use Information

The grid cell information is used exclusively to:

• Query the Sean Lahman baseball database via our API at brennanhurd.com/api/imgrid
• Display relevant player solutions within the game interface
• Provide Baseball Reference links for additional player information

What Information We Share

We do not share any information with third parties. The extension operates entirely between your browser and our baseball database API.

Data Transmission Security

All API communications use HTTPS encryption (https://brennanhurd.com/api/imgrid) to ensure secure transmission of grid queries. No personal data is transmitted - only baseball statistic combinations like "Yankees + Home Runs".
