What we collect personal information and why we collect it


When visitors add a comment to this site, the data displayed in the comment form is collected, the visitor’s IP address and the user agent string that defines the browser, which helps to detect spam.

Gravatar can be provided with an anonymous string created from your email address (also called a hash) to determine whether you are using the service. Gravatar privacy policy is available here: After you approve your comment, your profile picture is visible to the public in the context of your comment.


If you are uploading images to this website, you should avoid uploading images with embedded location data (EXIF GPS). Site visitors can download and view any location data from images on the web.
