What personal data we collect and why we collect it

Log files

As with most other websites, we collect the data contained in log files. This include your IP (Internet Protocol) address, the browser you used to visit our site (like Firefox or Chrome), the time you visited our site and which pages you visited throughout our site.


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. Only your comment, name, and optionally your website address (if you provide it) will be shown on the public side.

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: If you use this service, your profile picture is visible to the public in the context of your comment.


This site uses cookies – small text files that are placed on your machine to help the site provide a better user experience.

In general, cookies are used to retain user preferences, store information for things like shopping carts, and provide anonymised tracking data to third-party applications like Google Analytics. As a rule, cookies will make your browsing experience better.

However, you may prefer to disable cookies on this site and on others. The most effective way to do this is to disable cookies in your browser. We suggest consulting the Help section of your browser.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos from YouTube). 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 tracing your interaction with the embedded content if you have an account and are logged in to that website.


Like many websites, this site uses Google Analytics to track user interaction. We use this data to determine the number of people using our site, to better understand how they find and use our web pages and what articles are the most popular ones, so we can create better content.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we 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, 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.

Where we send your data

Visitor comments may be checked through Akismet, an automated spam detection service provided by Automattic. Their privacy policy is available at
