Privacy Policy

Who we are

This is the privacy policy of the Grassroots Homogenisation Journal. Our website address is:

What personal data we collect and why we collect it


When visitors leave comments on the site we collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.

An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it; see Gravatar service privacy policy. After approval of your comment, your profile picture is visible to the public in the context of your comment.


If you upload images to the website, you should avoid uploading images with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website.

Contact forms

The information you filled in in a contact form will be stored by us and will be deleted on request.


We do not track our readers and as long as you are reading no cookies or similar technologies will be used to track you. If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you have an account and you log in to this site, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select "Remember Me", your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

If you edit or publish an article, an additional cookie will be saved in your browser. This cookie includes no personal data and simply indicates the post ID of the article you just edited. It expires after 1 day.

Embedded content from other websites

Articles on this site may include embedded content (e.g., videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website. We will work to reduce these tracking problems; any help is appreciated.


We do not use external analytics providers which may track our users. The administrators of the Grassroots Journal System and of the Grassroots Homogenisation Journal only analyse our web traffic log files in an aggregate manner to keep track of the use of our homepage.

Who we share your data with

We do not share your data with third parties, except for comments to check for spam (see below) and except for a hash of your email (see Gravatar service above). The administrators of the Grassroots Journal System and of the Grassroots Homogenisation Journal are the only people with access to non-public data.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue. Accepted comments are published under a Creative Commons Attribution license and are part of the scientific literature.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

Where we send your data

Visitor comments may be checked through an automated spam detection service. A hash of visitor emails may be send to the Avatar service to retrieve your information if you use this service.

Your contact information

In case of questions on our procedures, information on which data we store about you or requests for edits and deletions that cannot be made automatically please contact us.

Additional information

How we protect your data

We will ensure that the automatic updates of our operating system are performed and that computers have adequate virus protection software to minimize data loses.

What data breach procedures we have in place

In case we expect that your account has been hacked, we will inform you and request a new password to be used.
