German data protection authorities are famously fond of comprehensive privacy policies, and we are certainly willing to oblige:
When you read this blog
The server on which this blog is hosted will create the usual logfiles, collecting the data that your browser transmits to the server, i.e. information about
- type and version of the browser that you are using,
- the operating system of the device (PC, note-/netbook, talet etc./ that you are using
- the Referrer URL (meaning the website from which you have come to our blog)
- the host name of the accessing device
- the time of the server request
On a regular basis, these data cannot be related to a particular individual. And we certainly have no intention whatsoever to make any such attempt. We will not match the data against or bring the data together with other data. We only use the data for statistical purposes and will delete them when that purpose has been fulfiled
When you submit comments
You may comment on (most of) the posts on this blog. When you do that, we will (besides the comment itself, of course) store your name, your email address, the IP address that was allocated to your device when you submitted the comment, the exact time of your coment, and, if disclosed, the URL of you website.
The readers of our blog will get to know your name, your webiste (if applicable) and the time of your comment, and will if course read the comment itself. On the other hand, neither your email address nor the recorded IP address will be published.
We ask for your email address in order to be able to, for example, contact you when we or other readers have questions regarding your comment. We record the IP address to as well as possible protect ourselves from misuse of our comment function (i.e. spam and hardcore trolling). We will not use your email address or the recorded IP address for any other purpose, and certainly will not pass them on to third parties.
Your right to ask for information
Social Media Plugins
Our blog may implement so-called social media plugins, in particular Facebook, Inc.’s “like” button, Google’s “+1” button and Twitter, Inc.’s Twitter buttons. When you visit a page that displays one or more of such buttons your browser will establish a direct connection to the respective Facebook, Google and/or Twitter server and load the button from there. At the same time Facebook, Google and Twitter will know that the respective page on our blog has been visited.
We have no influence on the data that Facebook, Google and Twitter collect on the basis of the buttons. According to the available information, however, if you do not click on the respective Facebook, Google or Twitter button, no personally identifiable data will be collected and stored unless you have logged onto to your Facebook, Google or Twitter account. In that case certain user data (including your IP address at the time) may be collected and linked to the account information already present at Facebook, Google or Twitter, respectively. If you wish to prevent this, please log out of your social media accounts before visiting our website.
In addition, clicking a button may also lead to a collection of certain data, such as the user’s IP address. Facebook, Google and Twitter may set cookies, as well, unless you have disabled the acceptance and storage of cookies in your browser settings.
We receive no information from Facebook. Google or Twitter about which social media buttons you may have clicked or seen on our website, but, if at all, a summarized, non-person-related statistical report on the use of the buttons.
If you wish to obtain more information on the subject go to:
