Go Unfloc Yourself


A bundle for Symfony 5 that adds a Permissions-Policy header in all the responses to prevent the use of new Google's "Federated Learning of Cohorts" tracking method, namely FLoC.

Basically, it adds a specific header to every response to disable Google's usage of your site in it's FLoC tracking method.

For better performance, it is advised to edit the .htaccess or alter the webserver configuration.


If an existing Permissions-Policy header is found, the bundle will not change that value.

The added headers is: Permissions-Policy: interest-cohort=()


composer require loophp/go-unfloc-yourself-bundle


Once installed, there is nothing else to do.

Code quality, tests and benchmarks

Every time changes are introduced into the library, Github run the tests.

The library has tests written with PHPSpec. Feel free to check them out in the spec directory. Run composer phpspec to trigger the tests.

Before each commit some inspections are executed with GrumPHP, run composer grumphp to check manually.

The quality of the tests is tested with Infection a PHP Mutation testing framework, run composer infection to try it.

Static analyzers are also controlling the code. PHPStan and PSalm are enabled to their maximum level.


Feel free to contribute by sending Github pull requests. I'm quite reactive :-)

If you can't contribute to the code, you can also sponsor me on Github or Paypal.
