Overview
This category includes scripts that enhance privacy by blocking communications with hosts known for tracking and data collection.
A host is a domain name serving as an address for a computer or resource on the Internet. These hosts are often used by software applications, operating systems, and services to collect data, which can include personal information, usage patterns, and more.
By modifying the hosts file (a simple text file on your computer that maps domain names to IP addresses), these scripts stop your computer from connecting to servers that collect user data.
This not only reduces personal data sent to companies and third-party trackers, enhancing privacy, but may also optimize system performance by minimizing unnecessary network requests.
These scripts may interfere with the functionality of apps or services relying on the blocked data. Balance privacy with functionality according to your preferences and needs.
