What personal data we collect and why we collect it


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.

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: After approval of your comment, your profile picture is visible to the public in the context of your comment.


If you upload images to the website, you should avoid uploading images 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

In contact forms we collect the information you enter. These contain your Name, e-mail address, and the message you enter in the form. This information will be sent to our lab via e-mail, so we can respond to your request. The information you sent to us via the contact form will be kept for service purposes, but we do not use this information for marketing purposes. If you disagree with this information to be transmitted, processed or stored, please do not use the contact form.


If you leave a comment on our 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.

If you have an account and you log in to this site, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, fonts 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.
