I am committed to safeguarding the privacy of my website visitors; this policy sets out how I will treat personal information I collect from you through the website.

1. What information do I collect?

I may collect, store and use the following kinds of personal data:

1.1 Website visits


When you leave comments on the site I collect the data shown in the comments form, and also your IP address and browser user agent string to help spam detection.

An anonymised string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: After approval of your comment, your profile picture is visible to the public in the context of your comment.

1.3 Contact forms

My contact form service is offered in accordance with GDPR, Art.6 (1)(b).

When you send me a message from my contact page I only ask for your email address, a name, the subject of your message and of course the message itself. This information is necessary to start a proper conversation that aims to answer your request.

All messages I receive from my contact page will only be used to process the respective subject of your message. During the evolving conversation I will not send any off-topic information like advertising or product recommendations.

When you get in contact with me (for example by email or via the form on the website) I will keep records of what is communicated. This is to ensure I have a record of my discussion for future reference and so I can improve the website and my services.

1.4 Cookies

If you leave a comment on my site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you have an account and you log in to this site, I will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, I will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

1.5 Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, audio streams etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website. These include Google, YouTube, Vimeo, Facebook, Twitter, Soundcloud, and Gumroad.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracing your interaction with the embedded content if you have an account and are logged in to that website.

1.6 Google Analytics

I use Google Analytics to collect and store anonymous statistical data about my users’ use of the website. Google Analytics uses cookies, which are text files placed on your computer to help the website analyse how you use the site. The information generated by the cookie is transmitted to and stored by Google on servers in the United States. Google will use this information on my behalf to evaluate your use of my website. The IP address that your browser transmits within the scope of Google Analytics will not be associated with any other data held by Google.

The IP anonymisation feature is active on this website. That means your IP address will be truncated beforehand within the area of Member States of the European Union or other parties to the Agreement on the European Economic Area. This happens prior to transmission to the United States.
