Data Privacy and Data Protection Statement

I take data protection and data privacy seriously. I have no intention to collect any personal data from you that is not willingly provided by yourself. I have no intent to use your personal data for any purpose that was not obvious at the moment you provided the data.

All data is collected and processed in compliance with the GDPR (General Data Protection Regulation).

I will never give your data to any third parties for their own use without getting your prior and explicit consent for each individual situation.

I do however use external systems (e.g. web servers, email servers) managed by other companies to store your data. The companies operating the data storage and processing systems for me are called Data Processors in the terminology of the GDPR.

The Data Processors I work with are contractually bound to treat any personal data I entrust to them strictly in accordance to our agreements and apply the standards of the GDPR to the data too.

Upon request, you are entitled to get a copy of the personal data I stored about you. You have the right to request that your personal data is deleted.

Here is a detailed list of the data I collect, where it is stored, and what I do with it.

When you visit this website

Web server log files

Whenever you visit and page on this site, your browser request will be stored in the web server log files.

What data is collected?

The request data collected includes the page requested and your public IP address.

Where is the data stored?

The data is stored on our web server hosted by Keyweb AG in Germany.

For what purposed do we collect the data and for how long will it be stored?

This data is used to detect and prevent technical problems with our website. It can be used to detect abuse, like hacking attempts and (D)DNS attacks, of the website.

While this data includes your IP address, which could be used to identify you as a person, we never combine the server log file data with other information that might allow us to identify you.

The only exception to this rule is abuse of the website. In this case we may pass on this log file data to the law enforcement authorities to investigate criminal activity.

Unless there was any suspicious activity that needs to be investigated, all server log file data is automatically deleted after 30 days.

We use Google Analytics to track visits to this website.

You IP address is anonymized before it is ever stored persistently.

Due to the self-imposed limitations to Google Analytics describe above, it is not possible to link any data we collect with Google Analytics to you as a person. For this reason, we do not consider this as personal data in the sense of the GDPR.
