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 plus additional information is collected by the Akismet anti-spam service. See below for details.

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


When you use the chatroom we gather user name, first name, last name and e-mail in order that you can open a user account, let the user login, be able to identify the user and communicate with them. Usernames, first and last names will be published on the site and in forum profiles, topics and replies, but email addresses will only be visible to administrators of the site. None of this information is shared with other parties, or used for any other purposes.


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.

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 tracing your interaction with the embedded content if you have an account and are logged in to that website.


We do not use analytics services external to our server. We analyse only anonymous access statistics by ourselves.

Who we share your data with

We do not share your data with any external parties.

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.

For users that register on our website (if any), we also store the personal information they provide in their 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

If you have an account on this site, or 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 an automated spam detection service.

For protection from spam we use the Akismet service as follows:

Akismet anti-spam service collects information about visitors who comment on the site. The information they collect depends on how we sets up Akismet for the site which may change in time, but typically includes the commenter’s IP address, user agent, referrer, and Site URL (along with other information directly provided by the commenter such as their name, username, email address, and the comment itself).

We use the ShortPixel service for reducing the size of images served from this web site. If you upload images or other media files they may be automatically or manually sent to the ShortPixel service to be compressed, as this reduces the workload of our server and results in pages loading faster:

When images are optimized via the ShortPixel online compressor, ShortPixel stores them for two hours, together with the optimization details. After that, they delete the images, but they keep the info for 40 days. 

If you use the share buttons at our site, you should be aware that to achieve this we need to send data to these services.

We embed a Facebook widget to allow you to see number of likes/shares/recommends and “like/share/recommend” our webpages. This widget may collect your IP address, your web browser User Agent, store and retrieve cookies on your browser, embed additional tracking, and monitor your interaction with the widget, including correlating your Facebook account with whatever action you take within the widget (such as “liking/sharing/recommending” our webpage), if you are logged in to Facebook. For more information about how this data may be used, please see Facebook’s data privacy policy:
