What personal information we collect and why we collect it


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

An anonymized string may be created from your email address (also called a hash) and provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy can be found here: After your comment is approved, your profile picture will be publicly visible in the context of your comment.

Contact forms


If you write a comment on our website, you may agree to save your name, email address and website in cookies. These are for your convenience so that you do not have to fill in all this information again when you leave another comment. These cookies are stored for one year.

Embedded content from other websites

Posts on this website may contain embedded content (e.g. videos, images, posts, etc.). Embedded content from other websites behaves exactly as if the visitor had 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

No data is shared with third parties.

How long we store your data

If you write a comment, it will be saved indefinitely, including metadata. This way we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

What rights you have to your data

If you have written comments on this website, you can request an export of your personal data from us, including any data you have provided to us. You can also request that we delete any personal data we hold about you. This does not include data that we are required to retain for administrative, legal or security reasons.

Where we send your data

Visitor comments are checked through an automated spam detection service.

Your data will not be transmitted to any third parties, apart from our web host.
