Disable Topics API is a WordPress plugin designed to enhance user privacy by disabling Google's Topics API tracking. This plugin adds a specific HTTP header to your WordPress site, preventing any tracking related to browsing topics. The header added is 'Permissions-Policy: browsing-topics=()', which effectively disables the Topics API. Importantly, if an existing 'browsing-topics' value is present, the plugin will not alter it, ensuring that current settings are respected.

This plugin is categorized under Business & Productivity and is available for free. However, it's important to note that Disable Topics API is no longer maintained and is available for adoption. Users looking for more information on Google’s Topics API and its predecessor, FLoC, can find resources linked within the plugin description, highlighting the privacy concerns associated with these tracking methods.
