What Personal Data I Collect And Why


When visitors leave comments on the site, I 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 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. Have a look at the 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 leave a comment on my 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.


I use Jetpack to track visitors to my site. Have a look at the Jetpack service privacy policy. My hosting company,, collects the IP address of anyone visiting my site, but only to track attacks on my site and to allow them to take steps to prevent those attacks.

How Long I Retain Your Data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so I can recognise and approve any follow-up comments automatically instead of holding them in a moderation queue.

What Rights You Have Over Your Data

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

Where I Send Your Data

Visitor comments are checked with Akismet, an automated spam detection service. Have a look at the Akismet service privacy policy.

Data may be sent outside the European Union by Automattic (the owner of Akismet, Gravatar and Jetpack). This company is registered with the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks.

My Contact Information

If you have any privacy-specific concerns, you can contact me, privately, via Direct Messages on Twitter.
