You have the rights listed below. You can assert these towards us. To assert these, please use the data provided above or send an email to:

Google Analytics

On our website we use Google Analytics. This service is offered by Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA (referred to here as “Google”). To provide the service, Google may store cookies on your device. Cookies are small text files that serve to recognise your browser. Google stores the following data when you use the website: In addition to the IP address, the time, location, duration and frequency of your website visit are stored. We have set up Google Analytics to make the IP address anonymous. To do this, the IP address is shortened. Google uses the data to generate reports for us on the use of our web pages. This enables us to recognise user traffic on our website so that we can optimise it on the basis of this information. Google will share the information with third parties, if required to do so by law. Google will never associate your IP address with other data. As part of the Google Analytics processing, personal data is transferred to the United States. In this case, the IP address is always anonymised on servers in member states of the European Union before it is transferred to the USA. Personal data is transferred to the US in accordance with the European Commission decision on adequacy of 12 July 2016 (“EU-US Privacy Shield”).

Opting out of data collection

You can opt out of data collection by Google Analytics as follows: Google provides an opt-out add-on that you can install in your browser. Once this is correctly installed in your browser, Google no longer collects data as part of its Analytics program. Opting out of the Analytics program has no effect on any data transfer to other web services.

The opt-out add-on can be downloaded from Google’s website here:

Alternatively, you can click the following link to set an opt-out cookie for the browser that you use. Data will then no longer be transferred to Google Analytics when you visit this website in future: click here. Please note that the opt-out cookie may be deleted. The deletion of the opt-out cookie depends on your individual browser settings. If the cookie is deleted, you must restore it by clicking the above link again. If you opt out of collection of data by Google Analytics, it is possible that you may not be able to properly use all of the services we provide.

Google Maps

Parts of our website use functions from Google Maps to integrate map data. This content is provided by Google Inc., 1600 Amphitheater Parkway Mountain View, CA 94043, USA (“Google”). When you visit our website, your browser loads the necessary code from Google. To do this, the browser you are using must connect to Google’s servers. This tells Google that our website has been accessed via your IP address. At the same time, Google may place cookies on your device, unless you have prohibited the use of cookies in your browser, or may read cookies. Location data may also be collected if you allow it in your browser settings.

We use Google Maps to make our website attractive and easy to use, and so that you can easily find us at the places shown on it. This constitutes a legitimate interest within the meaning of Article 6(1)(f) of the GDPR. The transfer of data to the USA takes place in accordance with the European Commission’s Implementing Decision (EU) 2016/1250 (EU-US Privacy Shield).

We gather your IP address to allow data to be transferred to Google. You are not obliged to provide this information, but if you do not, you will not be able to use the relevant parts of our website.

For more information, see Google’s Privacy Policy, which can be found at


To protect data input forms on our site, we use the service “reCAPTCHA” service of Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043 USA, (referred to here as “Google”). This service can distinguish whether input in a form is genuine input from a human user, or misuse by a bot. To implement the functionality, your referrer URL, IP address, website visitor behaviour, information about the operating system, browser and time spent on the site, cookies, presentation instructions, scripts, information about user input behaviour and mouse movements around the reCAPTCHA checkbox are transferred to Google. Google uses the information thus obtained for purposes such as digitizing and optimizing its own various services. Google will not associate the IP address submitted by reCAPTCHA with any other data unless you are logged into your Google account at the time you use the reCAPTCHA plug-in, in other words, the time you visit our website. If you want to prevent this transfer and storage by Google of data about you and what you do on our website, you must log out of Google before visiting our website. The terms of use of the reCAPTCHA service can be found at:

Use of YouTube components with advanced privacy mode

On our website, we use components (videos) from the company YouTube, LLC 901 Cherry Ave., 94066 San Bruno, CA, a subsidiary of Google Inc., Amphitheater Parkway, Mountain View, CA 94043, USA. The “extended privacy mode” option provided by YouTube is enabled. This means that only the information required for the presentation of the videos – in other words, the information about which of our web pages you visit – is transferred to the service provider. If you are logged into YouTube while visiting our website, the transferred information will be assigned to your YouTube member account. You can prevent this by logging out of your member account before visiting our website.

When you open a page with an embedded YouTube video, you are connected to the YouTube servers so that the content (i.e. the video) can be shown on our site via a message to your browser.

Google provides additional YouTube privacy information at the following link:

Use of the web shop

When you order from our web shop, we have to collect the personal data from you that is necessary to conclude the contract. The mandatory information required for the contract is clearly marked, and all other information is voluntary. The data you provide is used to process your order. To do this, we can pass on your payment data to our bank. The legal basis for this is Article 6(1)(b) of the GDPR.

Due to various obligations regarding storage and documentation, we have to keep your address, payment and order data for a period of ten years. These obligations arise from legislation such as the German Commercial Code (HGB) and the Fiscal Code of Germany (AO). The ordering process is encrypted using TLS technology. The encryption serves to prevent unauthorised access by third parties to your personal data.

Registration portal

To use our portal, you register by specifying your e-mail address, a password of your own choice and your user name. You are free to choose your user name. There is no obligation to use your real name. You can use a pseudonym if you want. Registration takes place using a double-opt-in procedure. An e-mail is sent to your specified address, containing a link to confirm your registration. If confirmation is not received within 7 days, the registration is automatically deleted from our database. The e-mail address, user-defined password and user name are mandatory; you can provide all the other information voluntarily by using the portal.

When you use the portal, we store the data that we need to fulfil the contract until you delete your access details. This also applies to any data that you voluntarily provide. You can manage and edit all information in the secure customer area. To let you know about important changes, such as changes to the scope of the offer or technical modifications, we use the e-mail address you provided when registering.

The legal basis for this is Article 6(1)(f) of the GDPR.

Data transfer to third countries outside the EU

When data is processed by Google Analytics, Google Maps, reCAPTCHA and YouTube, some of it may be transferred to countries outside the European Union (these are known as third countries). In this case it is the United States.

Commission Implementing Decision (EU) 2016/1250 of 12 July 2016 pursuant to Directive 95/46/EC of the European Parliament and of the Council on the adequacy of the protection provided by the EU-U.S. Privacy Shield (EU-U.S. Privacy Shield)”.
