Privacy policy


When a visitor to the site leaves a comment, we collect the data visible in the comment form, as well as the visitor’s IP address and browser signature to help us detect spam.

An anonymised string created from your email address (a so-called hash) can be sent to the Gravatar service to check if you are using it. The privacy policy of the Gravatar service is available at When the comment is approved, your profile picture is publicly visible in the context of your comment.


If you are a registered user and upload images to the site, you should avoid uploading images with EXIF location tags. Visitors to the site can download and read full location data from images on the site.


If you leave a comment on our site, you can choose to have your name, email address and website address saved in a cookie file so that when you post another comment the above information is conveniently populated. Cookies expire after one year.

If you visit the login page, we will create a temporary cookie to verify that your browser accepts cookies. It does not contain any personal data and will be deleted when the browser is closed.

When you log in, we also create a number of cookies to store your login information and the screen options you have selected. Login cookies expire after two days and screen option cookies expire after one year. If you tick the “Remember me” box, the login will expire after two weeks. If you log out of your account, your login cookies will be deleted.

If you edit or publish an article, an additional cookie will be stored in your browser. This cookie does not contain any personal data and simply points to the identifier of the article you have just edited. This cookie expires after 1 day.

Embedding content from other sites

Articles on this site may contain embedded content (e.g. videos, images, articles, etc). Content embedded from other sites behaves as if the user had visited the specific site directly.

Sites may collect information about you, use cookies, attach additional third-party tracking systems and monitor your interactions with the embedded material, including tracking your interactions with the material if you have an account and are logged into that site.

With whom we share data

If you request a password reset, your IP address will be included in the message you send.

How long we store your data

If you leave a comment, its content and metadata will be stored indefinitely. This allows us to recognise and approve subsequent comments automatically, without sending them to moderation each time.

For users who have registered on our website (if any), we also store personal information entered in the profile. Any user can view, correct or delete their personal information at any time (with the exception of their user name, which cannot be changed). Site administrators can also view and modify this information.

What rights do you have to your data

If you have a user account or have posted comments on this site, you may request that we provide you with a file containing an exported set of your personal data in our possession, including all data provided by you. You may also request that we delete all of your personal information in our possession. This does not apply to any data that we are obliged to retain for administrative, legal or security reasons.

Where we send your data

Visitor comments can be checked using an automated spam detection service.
