What personal data we collect and why we collect it


Comments and user avatars, including the Gravatar service, are disabled on this website by default.

If visitor comments are selectively enabled, this site collects the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection. If user avatars and the Gravatar service are enabled, 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: In such a case, after approval of  a comment, the user’s profile picture is visible to the public in the context of the comment.


Users should avoid uploading images to this website with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website.

Contact forms

This site uses a contact form for user feedback and interaction. When a user submits a contact form, the site collects the name, email and message text entered into the form by that user, and holds it for the purpose of reviewing and responding to the user message. This site retains submitted contact form data indefinitely. No information submitted through the contact form and held by the site is used for marketing purposes or shared with third parties.


Comments are disabled on this website by default. If visitor comments are selectively enabled, site visitors may opt-in to save name, email address and website in cookies, for the user’s convenience to avoid entering user details again when leaving another comment. These cookies last one year.

For users with an account on this site  who log in, this site sets a temporary cookie to determine if the user’s browser accepts cookies. This cookie contains no personal data and is discarded when the user closes the browser. Upon login, the site also sets up several cookies to save the user’s login information and your screen display choices. Login cookies last two days, and screen options cookies last a year. When a user selects “Remember Me” the login will persist for two weeks.Login cookies will be removed upon logging out of the user account.

When a user edits or publishes an article, an additional cookie will be saved in the user’s browser. This cookie includes no personal data and simply indicates the post ID of the article 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 the visitor, use cookies, embed additional third-party tracking, and monitor interaction with that embedded content, including tracing the user’s interaction with the embedded content if the user has an account and is logged in to that website.

Who we share your data with

By default this website does not share any personal data.

How long we retain your data

Comments are disabled on this website by default. If visitor comments are selectively enabled, a comment and its metadata are retained indefinitely. This is for automated recognition and approval of any follow-up comments (rather than holding them in a moderation queue).

For users that register on this website, this site also stores personal information provided in the 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

Comments are disabled on this website by default. If a user has an account on this site, or is a user who has left comments (if visitor comments are selectively enabled), the user may request to receive an exported file of their personal data held by the site, including any data the user has provided. The user can also request deletion of any personal data held by the site. This does not include any data this organization is obliged to keep for administrative, legal, or security purposes.

Where we send your data

Visitor comments may be checked through an automated spam detection service.
