Handling of your Personal Data
Visitors do not have an account on this website, they are not registered here, and they do not log in. Therefore, it should be noted that although we collect some information on how often an individual webpage is visited, this information is not directly linked to you as a person. (A few users are also registered with an account, and more information about them can be found at the bottom of this page.) This website stores information about which pages are visited but no information about who visits them.

Who are registered users on this web site?
A few invited persons are authors of pages on this site. They are registered users and they have an account. Information will be collected as if they were non registered users. On top of that we also retain the personal information they provide in their user profile including their name, e-mail address and any narrative they choose to put in. All registered 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. These registered users can at any time contact us for information or to be deleted from our system.
Registered users and “cookies”
If you as an author 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. When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed. If you edit or publish an article, an additional cookie will be saved in your browser. This cookie includes no personal data and simply indicates the post ID of the article you just edited. It expires after one day.
How do we store information about registered users
Information about users with an account (invited authors) is stored on a web server physically located within the European Union (EU). The name and email address of invited authors with a login account are visible on the page they have created. No other personal information is stored except for a brief description created by the authors themselves. The web server is physically stored in a large locked data center. The server is maintained and regularly updated to ensure that software security issues are proactively managed. No information at all is stored for visitors who do not log in.
