No Google Chrome Flock Tracking (module for Omeka S)
New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.
No Google Chrome Flock Tracking is a module for Omeka S that adds a HTTP header to invite Google not to track visitors via the browser Chrome. Indeed, with the new versions of Chrome and derivative browsers, Google steals directly your browsing history even if you forbid it, creates a profile, and gives access to it to any other tracking tool via a unique flock identifier.
Of course, this tracking is currently illegal in most of the countries, whatever Google says, but now this header is required to invite Google to respect the law (there will be a small fine in some years). More information to clean up the web or in French.
You can check your current browser on amifloced.org.
This module can be used in conjunction with the module EU Cookie Bar, that warns about the tracking by cookies when Google analytics or Facebook buttons are used to steal data of your visitors.
This module is useless if you can access to the config of your server or if you can add this in the Apache file ".htaccess" at the root of Omeka:
Header always set Permissions-Policy: interest-cohort=()
This module simply adds these lines automatically if not present, after some checks. Once installed, the module can be removed. Of course, it is better to include the line above in the main config files of Apache.
Important: The Apache module "headers" must be enabled first:
sudo a2enmod headers sudo systemctl restart apache2
Nginx and other servers are currently not supported. You can find details of config for them here.
Note that the header must be added to any response, not only to the Omeka ones: if the assets (images, js, css…) are not protected, Google will add (or maybe not) the site in the visitor profile anyway.
