My Privacy Policy

This is the privacy policy of This website is maintained by me, Markus Echterhoff (Contact, Legal Information).

I process your data in accordance with the European General Data Protection Regulation (GDPR) and the Austrian Telekommunikationsgesetz (TKG).

Personal Data

Maintaining this website involves the handling of personal data. In this section I explain which personal data I collect, why I collect it, and for how long I store it.

Web Server Log Files

In order to investigate technical and security related issues with the website, I keep web server log files that contain personal data as part of technical information that your web browser makes available. These are your Internet Protocol (IP) address, date and time of visit, requested file, request method, protocol version, and user agent string (typically contains browser type and operating system). Web server log files are automatically deleted after one year.

Data Processors

In order to offer this website, it is necessary to have others process personal data for me. I have data processing agreements with the follwing entities.

Your Rights

You have the rights to learn which personal data I store about you (Art. 15 GDPR), rectify this data (Art. 16 GDPR), receive a copy of it (Art. 20 GDPR), and have it deleted if no overriding reasons exist for me to keep it (Art. 17 GDPR). You have the rights to restrict (Art. 18 GDPR) and object to (Art. 21 GDPR) my usage of your personal data. Please contact me if you wish to exercise any of these rights.

If you believe my use of your personal data is unlawful, you have the right to lodge a complaint with a supervisory authority (Art. 77 GDPR).

Measures for Protection of Personal Data

All communication between your browser and this website is SSL encrypted. Requests for unencrypted pages (http) are automatically redirected to an encrypted connection (https).


Cookies are small text files that are sent back and forth between a web browser and a web server. Their purpose is to allow information to persist between page loads. Without cookies, the web server would forget about you each time you load a page. Therefore, cookies are used for things like remembering logins and settings, and making a connection between subsequent page loads for web analytics purposes (tracking). If you do not want to receive cookies, you can configure your browser to reject them. Cookies can also be inspected and deleted from within modern browsers.

I set several cookies for web analytics. These are pseudonymized. The session cookie is deleted when you close your browser, the browsing session tracking cookie lasts for 30 minutes, and the longterm tracking cookie lasts for 13 months. See also section Web Analytics.

Web Analytics

Web analytics means collecting and processing information about how a website is used. When you visit this website, I collect technical information that your browser makes available, such as your browser type, operating system and screen resolution (see this Matomo FAQ for a full list). Your IP address is used to determine your Internet Service Provider (ISP) and the city where the Internet access is located (geolocation). I only keep an anonymized version of your IP address in my database, so that the information I collect cannot be linked to you.

I use these data to improve my website, e.g. fix bugs, discover usability issues, find out which of my pages are more popular than others, and learn where my visitors are coming from and whether they are coming back. Pseudonymous analytics data with anonymized IP addresses is stored indefinitely so I can analyze long term trends.

My web analytics software is Matomo. For maximum privacy, the software is self-hosted on the same infrastructure as my website. I do not share my web analytics data, and I do not use it to personalize ads. The web analytics software is configured to respect the Do Not Track (DNT) setting of your browser. Additionally, you can opt-out of being tracked below.
