Privacy Policy for X/Twitter Country Flags & Blocker
Last Updated: November 25, 2025

This Privacy Policy describes how the X/Twitter Country Flags & Blocker extension collects, uses, and discloses information.

1. Data Collection
   We prioritize user privacy. The extension operates primarily on your local device. However, to provide community-sourced location data, the extension communicates with a third-party database (Cloudflare KV).

Public Data: We collect and store public Twitter usernames (e.g., @handle) and public location strings (e.g., "USA") found on timelines.
IP Addresses: Your IP address is transmitted to the Cloudflare server solely for the purpose of preventing abuse (spam/fake data). We do not store your IP address. It is immediately cryptographically hashed (SHA-256) upon receipt. We cannot reverse this hash to identify you.
No Personal Data: We do not collect any browsing history, passwords, Direct Messages (DMs), or emails.
2. How Data is Used
Location Verification: Public location data is stored in a shared community database to reduce X/Twitter API usage for all users.
Reputation System: The hashed IP identifier is used to calculate a "Trust Score" to verify the accuracy of submitted data.
3. Third-Party Services
Cloudflare: We use Cloudflare Workers and KV Storage to host the community database. Cloudflare may process network requests in accordance with their privacy policy.
4. User Control
You can disable the extension at any time. You can also view the full source code of this extension on GitHub to verify these claims, as this project is open source.
