What personal data do we collect from you and why


When you leave a comment on our website, the data entered in the comment form, your IP address and the user agent string of your browser are collected to help us detect spamming.

An anonymized string created from your e-mail address (also called hash) can be sent to the Gravatar service to check if you are using it. The privacy policy of the Gravatar service is available here: After the validation of your comment, your profile picture will be visible to the public next to your comment.


If you upload images to the website, we advise you to avoid uploading images containing location data (GPS EXIF). Visitors to the website can download and extract location data from these images.

If you submit a comment on our website, you may be asked to save your name, e-mail address and website in cookies. That is only for your comfort so that you do not need to enter this information again if you post a new comment. These cookies will expire after one year.

If you have an account and log into this website, a temporary cookie will be created to determine whether your browser accepts cookies. This cookie does not contain personal data and will be deleted automatically when you close your browser.

When you login, we will also set up a number of cookies to save your login information and screen preferences. Login cookies expire in two days, and screen cookies in one year. If you check “Remember me”, your cookie will be kept for two weeks. If you log out of you account, the login cookie will be deleted.

By editing or publishing a publication, an additional cookie will be saved in your browser. This cookie does not include any personal data. It simply indicates the ID of the paper you just edited. It expires after one day.

Embedded content from other sites

Articles on this site may include embedded content (e.g. videos, images, articles). Content embedded from other sites behaves in the same way as if the visitor visited the other site.

These websites may collect data about you, use cookies, embed third-party tracking tools and track your interactions with embedded content if you have an account connected to their website.


How long we keep your data

If you leave a comment, the comment and its metadata are kept indefinitely so that we can recognise and approve subsequent comments automatically, rather than keeping them in the moderation queue.

We also store personal data from user profiles (if any) who register on our website. All users can view, modify or delete their personal information at any time (except their username). Site managers can also view and edit this information.
