A simple zero-config plugin to opt-out of Google “Federated Learning of Cohorts” (FLoC).
Disable the tracking of your users with FLoC
Federated Learning of Cohorts (FLoC) is a replacement for third party cookies in chromium browsers like Chrome to target users with ads based on their interests. The proposed solution is better than using
third party cookies, but it still raises concerns in terms of privacy and data protection.
How does this plugin work?
This plugin tells your WordPress system to send a special header that disables FLoC on your website. There is no configuration needed besides installing the plugin.
If you are a developer, we encourage you to follow along or contribute to the development of this plugin on GitHub.

Blocking Methods
This plugin offers different methods implement the FLoC blocking HTTP header.
- None / Allow FLoC: This method does not provide an opt-out from FLoC.
- Simple / PHP: Works for most WordPress setups. Uses the “wp_headers” filter to provide the HTTP header.
- Apache / .htaccess: When you have to circumvent your cache. Only works on apache servers with the “mod_headers” module installed. Writes the HTTP header into the .htaccess file.
Compatibility with Cache Plugins
This plugin relies on the ability to deliver HTTP headers to the browser. Some Cache Plugins actively strip these HTTP headers and therefore invalidate the purpose of this plugin.
These cache plugins are known to be compatible with the Simple method:
- WP Super Cache – You have to activate the “Cache HTTP headers with page content.” checkbox in the Advanced Tab of the WP Super Cache Settings.
