Data protection


This data protection declaration is intended to inform the users of this website in accordance with the Federal Data Protection Act and the Telemedia Act about the type, scope and purpose of the collection and use of personal data by the website operator Detmer Hasselmann (see Imprint ) .

The website operator takes your data protection very seriously and treats your personal data confidentially and in accordance with legal regulations.

Keep in mind that data transmission over the Internet can always be subject to security gaps. Full protection against access by strangers is not possible.

Access data

The website operator or website provider collects data about access to the site and saves it as “server log files”. The following data are logged:

  • Visited website
  • Time of access
  • Amount of data sent in bytes
  • Source/reference from which you came to the page
  • Browser used
  • Operating system used
  • IP address used

The data collected is only used for statistical evaluations and to improve the website. However, the website operator reserves the right to check the server log files retrospectively if there are specific indications of illegal use.


This site uses cookies. These are small text files that are saved on your device. Your browser accesses these files. The use of cookies increases the user-friendliness and security of this website.

Common browsers offer the option of not allowing cookies. Note: There is no guarantee that you will be able to access all functions of this website without restrictions if you make the appropriate settings.


The website operator uses the ” WP YouTube Lyte ” plugin, which ensures that your data is not transferred to YouTube when you enter a page with embedded videos. The contributed images are cached on the server that also houses the website. The plugin only establishes a connection to YouTube when you as the user actively click the play button.

If you click the play button, the YouTube server will be informed about the page of our website you have visited. If you were also logged into your YouTube account, you would enable YouTube to assign your surfing behavior directly to your personal profile. You can nullify this possibility of assignment if you log out of your account beforehand. Further information on the collection and use of your data by YouTube can be found in the data protection information at .

Dealing with personal data

The website operator only collects, uses and passes on your personal data if this is permitted by law or if you consent to the data collection.

Personal information is all information that serves to identify you and which can be traced back to you – for example, your name, email address and telephone number.

Dealing with contact details

If you contact the website operator through the contact options offered, your details will be saved so that they can be used to process and answer your request. This data will not be passed on to third parties without your consent.

Dealing with comments

This website uses the “Remove IP” plugin, which prevents your IP address from being saved in connection with your comments. This expressly does not refer to the “server log files” mentioned above, but only to the storage of the IP in connection with your comments on the website.

To prevent misuse of the comment function, all comments are checked by us and activated manually when approved.


You have the option of subscribing to both the entire website and comments as a feed. You do not need to leave an email address for this purpose, just bookmark the feed in your browser.

Google Fonts

We currently refrain from using Google Fonts, as long as it is not clear how they can be used in compliance with the GDPR.

Rights of the user: information, correction and deletion

Upon request, you as a user will receive free information about which personal data has been stored about you. If your request does not conflict with a legal obligation to store data (e.g. data retention), you have the right to correct incorrect data and to block or delete your personal data.
