As a user of our website, you will find all the information you need about how, to what extent, and for what purpose we and third-party service-providers collect and use your data in this data protection declaration. We collect and use your data in strict compliance with statutory requirements, in particular those of the EU General Data Protection Regulation (GDPR) and the revised version of the Federal Data Protection Act. We are only too aware of our obligation to observe the confidentiality of your personal data, and are therefore scrupulous about working within the limits set down by law. Where possible, we will collect this personal data on a voluntary basis. In addition, we will only divulge this data to a third party with your express consent. We ensure that especially confidential data, e.g. with respect to payments and any enquiries you make to us, is protected by a high level of security through the use of SSL encryption. However, please be aware of the general risks of internet use which are beyond our control. Data contained in email correspondence in particular are not secure unless you take additional precautions and could, under certain circumstances, be collected by a third party.

Purpose of data processing

When you use our website, the following data are stored for organisational and technical reasons: the names of the pages you have called up, of the browser you have used and of your operating system, the date and time of access, the search engines you have used, the names of downloaded files, and your IP address.

We analyse this technical data anonymously and purely for statistical purposes, so that we can continue to optimise our online presence and design our internet features to be even more user-friendly. These data are stored on secure systems in isolation from other personal information. They are not traced back to an individual user.

Processing of personal data

In accordance with the principles of data avoidance and minimisation, we process personal data only to the extent and for as long as necessary for use of our website and/or as prescribed by law. We take the protection of your personal data seriously, and will ensure that we comply strictly with the relevant legislation and with this data protection declaration when collecting and processing personal data. If the purpose for collecting the data no longer applies and/or at the end of the statutory retention period, the data which has been collected will be blocked or erased. Our website can be used routinely without personal data having to be divulged. If we collect personal data – such as your name or email address – then we will do so on a voluntary basis. Unless you give us your express consent, third parties will not be made privy to this data. Please note that as a general rule, data cannot always be transmitted securely online. In email correspondence in particular, no guarantee of security can be given when data are exchanged.

The data we collect will not be used for automated decision-making in individual cases, or for profiling or scoring purposes.

Your rights as a data subject

At any time you can receive, free of charge, information about the personal data we hold on you, as well as about the origin, the recipient and the purpose of data processing. You are also entitled to require rectification, blocking or erasure of your data. This excludes data which we are required under law to retain or which we need to enable us to transact our normal business. To ensure that data can be blocked at any time, it is kept in a lock file for control purposes. If your data are not subject to a statutory archiving obligation, we will erase them upon request. If the archiving obligation applies, we will block your data. If you have any questions or concerns about the rectification, blocking or erasure of personal data, please contact our data protection officer, using the contact details shown in our data protection declaration and/or at the address given in the imprint.

If you do not believe that your rights concerning the handling of your personal data are being fully respected, you are entitled to lodge a complaint with the relevant supervisory body.

A contact form is available on our website which you can use to get in touch with us electronically. If you decide to take this opportunity, the data entered in the form will be transmitted to us for processing. These data comprise:

Your email address and possibly your name

When you send the message, the following data will be stored in addition:

Your IP address, and the date and time when you sent the form

Before sending your request, your attention will be drawn to this data protection declaration and you will be required to click a box indicating that you have received the information. Alternatively, you can contact us via the email address provided. In this case, the user’s personal data transmitted with the email will be processed.

No data will be divulged to third parties in association with this. The data will be used exclusively for processing the contact request. Once your enquiry has been dealt with, the personal data from the form will be deleted immediately. Other personal data collected during the sending process will be deleted within a maximum of seven days. We will delete your personal data immediately if you so request.

We use cookies on our website. These small text files are stored on your PC by our server. They help us to display our website and you to navigate your way around it. Cookies collect data about your IP address, your browser, your operating system and your internet connection. We do not link this information with personal data, and do not divulge it to third parties. We never use cookies to install malware or spyware on your computer. You can also use our website without cookies, although some of its displays and functions may only work to a limited extent. If you wish to deactivate the cookies, you can do so by making special adjustments to your browser. Please use the browser’s ‘Help’ function to make the appropriate changes. You can manage online advertising cookies via the following links: for the USA and for Europe.

Collection of access data

For technical reasons, certain data must be collected in order to deliver and display content on our website. When you access our website, these so-called server log files are recorded by us or by the web space provider. These log files cannot be traced back to you or your personal details. The corresponding information comprises solely the name of the website, the file, the current date, the quantity of data, the web browser and its version, the operating system used, the domain name of your internet provider, the referrer URL (the web page from which you accessed our site) and the corresponding IP address. We use this data to display and deliver our content and for statistical purposes. This information helps us to provide and constantly improve our features. We also reserve the right to verify the above data retrospectively if there are grounds for suspecting improper use of our site.

Third-party content and services

Under certain circumstances, our website may include content and services provided by other parties which complement our own features. Examples include maps from Google Maps, YouTube videos and graphic material from other websites. Use of these third-party services tends to require the transmission of your IP address. It is therefore possible for these providers to become privy to and also store your user IP address. We make every effort to involve such third parties only inasmuch as the respective provider uses the IP address for the sole purpose of delivering content. However, if a third-party provider stores the IP address, for instance for statistical reasons, then this is beyond our control. We will notify the user immediately if we become aware that third-party providers are storing data in this way. In this respect, you should please also read the specific data protection declarations of individual third-party content and service providers whose services we use on our website.

You will also find such information in this data protection declaration.

SSL encryption

Our website uses SSL encryption if our users’ confidential or personal content is to be transmitted. This encryption is activated, for instance, when you make payments or send us enquiries via our website. Please note that SSL encryption is activated by corresponding actions on your part. The use of encryption is easy to detect: the text in the browser line changes from ‘http://’ to ‘https://’. Data with SSL encryption cannot be read by third parties. You should only transfer confidential information if SSL encryption is activated; if in doubt, please contact us.

Google AdWords

We use Google AdWords on our website, an online advertising programme from Google Inc. Conversion tracking is also used in association with this. Google AdWords uses this tool to set a cookie on your PC if you reach our website via a Google advertisement. The cookie expires after thirty days. It cannot be traced back to you personally. If you visit our website as a user and the cookie is still in operation, both we and Google will be aware that you clicked on the corresponding advertisement and were referred to our website. Each Google AdWords customer is allotted a different cookie. This means that cookies cannot be tracked via the websites of AdWords customers. The data collected by conversion cookies are used to prepare conversion statistics for AdWords customers. This allows us as customers to determine the total number of users responding to our advertisement and then being referred to a website provided with a conversion-tracking tag. This process does not supply us with any information which would allow us to identify you personally as a user. If you reject the tracking process, the cookie for Google conversion tracking will be deactivated via your internet browser. If you want to find out more, use the ‘Help’ function of your browser for further information. More details about Google’s data protection policy are available at

Use of Google Analytics

This website uses Google Analytics, a web analysis service of Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; ‘Google’). Its use includes the ‘Universal Analytics’ operating mode. This makes it possible to allocate data, sessions and interactions across several devices to a pseudonymous user ID, and thereby analyse a user’s activities across devices.

Google Analytics uses so-called ‘cookies’, text files which are stored on your computer and which allow your use of the website to be analysed. Cookie-generated information relating to your use of this website is generally transferred to a Google server in the USA and stored there. However, if you have activated the IP anonymisation function on this website, Google will first abbreviate your IP address in member states of the European Union and in other states which are signatories to the Agreement on the European Economic Area. The full IP address will only be sent to a Google server in the USA and abbreviated there in exceptional cases. The IP address communicated by your browser as part of Google Analytics will not be merged with other Google data. Google uses this information on behalf of the website operator to analyse the user’s use of the website, compile reports on website activities, and provide the website operator with additional services associated with website and internet use. Our justified interest in data processing also serves these purposes. The legal basis for the use of Google Analytics is Art. 15 Para. 3 Telemedia Act (TMG) and/or Art. 6 Para. 1 Letter f GDPR. Data transmitted by us and linked to cookies, user names (e.g. user IDs) or advertising IDs will be deleted automatically after fourteen months. Data whose retention period has elapsed is deleted automatically once a month. For additional information on terms of use and data protection, visit and/or

By adjusting your browser software appropriately, you can prevent the cookies from being stored: however, we would like to point out that doing so may prevent you from making full use of all of the functions of this website. You can also prevent Google from collecting and processing cookie-generated data which is related to your use of the website (including your IP address) by downloading and installing the browser add-on at Opt-out cookies will prevent your data from being collected on future visits to this website. To prevent data from being collected by Universal Analytics across various devices, you must complete the opt-out procedures on all of the systems you use. You can set the opt-out cookie by clicking here: <a href="javascript:gaOptout()"><strong>Google Analytics deaktivieren</strong></a>

Google Analytics Remarketing

We use the remarketing function of Google Inc. on our website to display to our visitors relevant advertisements which might be of interest to them in conjunction with Google. As part of this process, cookies are set on your computer. These are text files which recognise users when they access pages and are thus able to display advertisements which match their interests across the entire Google network. Google states that it does not collect any personal data in relation to this, and also that it establishes no links with other Google services. You can prevent the use of Google’s remarketing function by making the necessary adjustments at The use of cookies can also be deactivated at or by adjusting the settings in your browser. If necessary, you can use the ‘Help’ function. For further information about Google Remarketing and the general data protection declaration of Google, visit:

Google Maps plugin

We use a plugin of the online service Google Maps on our website. The operator of Google Maps is Google Inc., whose headquarters are at 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. When you use Google Maps on our website, information about the use of this website and your IP address are sent to a Google server in the USA and stored there. We have no knowledge of the precise content of the data which is transferred, or of how it is used by Google. In this context, the company denies merging the data with information from other Google services or collecting personal data. However, Google may divulge the information to third parties. If you deactivate Javascript in your browser, you will prevent the execution of Google Maps. However, you will not then be able to use the map display function on our website. By using our website, you consent to the collection and processing of information by Google Inc. in the manner described. Additional information about the data protection policy and terms of use for Google Maps are available here:

Data Protection Declaration for the use of YouTube

Our website uses plugins from YouTube, which is operated by Google. The operator of the site is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. If you visit one of our pages featuring a YouTube plugin, a connection will be established to the YouTube servers and the latter will be notified about which of our pages you have visited.

If you are logged in to your YouTube account, you are allowing YouTube to associate your surfing behaviour directly with your personal profile. You can prevent this by logging out of your YouTube account.
