Comments
When visitors leave comments on the site the data shown in the comments form is collected, and also the visitor’s IP address and browser user agent string to help spam detection.
An anonymised 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: https://automattic.com/privacy/. After approval of your comment, your profile picture is visible to the public in the context of your comment.
Cookies
If you leave a comment on this 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.
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.
How long is your data retained?
If you leave a comment, the comment and its metadata are retained indefinitely. This is so any follow-up comments can be recognised and approvied automatically instead of holding them in a moderation queue.
What rights you have over your data
If you have left comments, you can request to receive an exported file of the personal data held about you. You can also request any personal data held about you be erased. This does not include any data kept to comply with administrative, legal, or security obligtions.
Where your data is sent
Visitor comments may be checked through an automated spam detection service.
