Privacy Policy for X User Country Extension

Last Updated: March 7, 2026

Overview

X User Country ("the Extension") is committed to protecting your privacy. This privacy policy explains what data the Extension collects, how it's used, and your rights regarding that data.

Data Collection

Information Collected

The Extension collects and stores the following data locally on your device:

1. Username-to-Country Mappings: When you view an X.com (Twitter) user profile, the Extension scrapes that user's publicly available location information from their X.com "About" page and caches it.
2. Timestamp Data: The date and time when each country lookup was performed, used to implement cache expiration.

What We DON'T Collect

• We do NOT collect your personal information
• We do NOT collect your browsing history
• We do NOT collect your X.com credentials
• We do NOT track which profiles you view
• We do NOT transmit any data to external servers
• We do NOT use analytics or telemetry

How Data Is Used

All data is stored locally in your browser using chrome.storage.local. The data is used solely to:

1. Display country badges next to X.com usernames
2. Cache country information to reduce repeated requests to X.com
3. Improve performance and reduce load on X.com's servers

Data Storage

• All data is stored locally on your device in Chrome's extension storage
• Data is never transmitted to any external servers or third parties
• Cached country data expires after:
  • 7 days for successful lookups
  • 1 day for unsuccessful lookups (to allow for retries)

Data Sharing

We do not share, sell, or transmit any data to third parties. All data remains on your local device.

Third-Party Services

The Extension loads user profile pages from X.com (twitter.com) in hidden iframes to extract publicly available country information. This interaction is governed by X.com's own privacy policy and terms of service.

Your Rights and Control

You have full control over your data:

Clearing Cached Data

You can clear all cached country data at any time:

1. Method 1 - Extension Settings: Open the extension options page and click "Clear Cache"
2. Method 2 - Chrome DevTools:
   • Open Chrome DevTools (F12) on any x.com page
   • Go to Application → Storage → Extension Storage
   • Right-click on the extension → Clear
3. Method 3 - Reinstall Extension: Removing and reinstalling the Extension will clear all cached data

Disabling the Extension

You can disable or remove the Extension at any time through Chrome's extension management page (chrome://extensions/).

Data Security

• All data is stored locally using Chrome's secure storage APIs
• No data is transmitted over the internet
• The Extension only accesses publicly available information on X.com

Children's Privacy

The Extension does not knowingly collect data from children under 13. The Extension only processes publicly available information from X.com profiles.
