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. The Gravatar service privacy policy is available here: After approval of your comment, your profile picture is visible to the public in the context of your comment.


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 visit our login page, 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.

Who we share your data with

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

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.

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.

Matomo web analytics

This site uses Matomo to analyze traffic and help us to improve your user experience. Matomo is an open source web analytics platform. A web analytics platform is used by a website owner in order to measure, collect, analyze and report visitors data for purposes of understanding and optimizing their website. Matomo is running exclusively on the servers of our web provider. No cookies will be stored on your computer while this website analysis is being performed.

Matomo is processing the following personal data:

  • two bytes of the IP address of a user’s accessing computer or similar device (anonymous)
  • the web page viewed
  • the website (referrer) which linked the user to the web page viewed
  • the subpages called up from the web page viewed
  • the time a user spends on the web page
  • the frequency and/or number of impressions of the web page

The exclusive purpose of this web analysis is to optimize our online presence. Your personal data will neither be analyzed nor used for profiling or passed on to a third party. Given the anonymization of IP addresses in this context, any user’s interest in having their personal data protected is duly taken account of.

Should you disagree with even the anonymized storage and analysis of the above details, you may object to such storage and analysis at any time. In that case, an opt-out cookie will be written to your device’s web browser meaning that Matomo shall cease to collect any session data.

You may choose to prevent this website from aggregating and analyzing the actions you take here. Doing so will protect your privacy, but will also prevent the owner from learning from your actions and creating a better experience for you and other users.
