Privacy Policy for BlockLang

Last updated: June 24, 2025

Overview

BlockLang is a lightweight and privacy-friendly browser extension that helps you clean up your search results on Google and Bing by filtering out unwanted languages, domains, or sites. The extension works by automatically appending exclusion filters (like -site: or -lang:) to your search queries, giving you complete control over the types of results you see. It's fully customizable, 100% offline, and includes no tracking whatsoever.
