What personal data we collect and why we collect it

Besides where technically required, we do not collect or store personal data about you. However, the processes involved in serving you this website and its contents require at least the temporary collection and storage of your IP-address.

In addition, we may non-permanently store information about the requested resources in our server logs.


Whenever your browser requests content from this website, the request sent includes your IP-address. An IP-address uniquely identifies a computer on the internet, and is required to be able to accurately deliver the requested content back to your computer.

This IP-address is held by the server for as long as required to serve your request, and is deleted afterwards. We do not store your IP-address in our server logs.

Server Logs

The server providing this website stores information about the requests it receives in a logfile for technical reasons and for website access statistics. For each request, the following information is stored:

This information is required for technical reasons, specifically for managing the server and tracking down and solving any technical issues that may arise in the operation of the server and the software providing the services.

The access statistics merely identify the number of access to the website in a given time, and allow us to, e.g., discern the amount of interest in different parts of the website. Given that no personally identifiable information is stored in the logs, the statistics do not contain such information, either.

The Referrer URL

The referrer URL specifies the location which referred you to the page or other resource requested from the web server. This may be a web site containing a link to this blog. This information may be useful to us to diagnose problems with the website, in order to find the origin of missing links or similar.

In some cases, this address may contain additional information, such as the search terms being used in a search engine to find the web page. If you do not want this information to be exposed to any website you visit, you may want to consider deactivating the transmission in your browser. We have located a set of instructions for the most commonly used browsers:

Also, using the privacy mode of your respective browser may help: Specifically, Firefox

Who we share your data with

We do not share your data with anyone else except were required by law.

How long we retain your data

The information in the server log is retained as long as it is technically necessary, and cleared out regularly.

What rights you have over your data

The data collected is necessary for the operation of the website. Thus, you cannot object to the collection of this data.

However, you may request an export of data collected about you.

Where we send your data

We do not send your data to any third parties except when required by law.
