Personal data

Personal data is information about personal and factual circumstances, such as Name, address, telephone number and date of birth. Information that is not directly related to you does not constitute personally identifiable information.

In general, the use of our website does not require that you provide personal information. For individual services, such as However, it may be necessary to register for a seminar so that we can provide our services. For this we collect, use and process personal data of you. Of course, this is done only within the legal framework, as far as this is necessary and you have consented to it.

How long will my data be stored?

We process and store your personal information as long as it is necessary for the fulfillment of our contractual and legal obligations.
If the data are no longer required for the fulfillment of contractual or legal obligations, these are regularly deleted, unless their temporary processing is necessary for the following purposes:

Fulfillment of commercial and tax retention obligations: The Commercial Code (HGB) and the Tax Code (AO) must be mentioned. The deadlines for storage and documentation specified there are ten years.
Preservation of evidence in the context of the statutory statute of limitations. According to §§ 195ff. of the Civil Code (BGB) these limitation periods can be up to 30 years, with the regular limitation period is 2 years.


Which data protection rights do I have?

Each data subject has the right to information under Article 15 of the DS-GVO, the right of correction under Article 16 DS-GVO, the right to cancellation under Article 17 DS-GVO, the right to restriction of processing under Article 18 DS-GVO, the right to object under Article 21 DS-GVO and the right to data portability under Article 20 DS-GVO. With regard to the right to information and the right to erase, the restrictions under §§ 34 and 35 BDSG apply. In addition, there is a right of appeal to a competent data protection supervisory authority of the state of Baden-Württemberg (Article 77 DS-GVO i.V.m. § 19 BDSG).

You may revoke your consent to the processing of personal data at any time. This also applies to the revocation of declarations of consent that were given to us prior to the validity of the General Data Protection Regulation (DS-GVO), ie before 25 May 2018. Please note that the revocation only works for the future. Processing that took place before the revocation is not affected.

Where and how do we collect and process your data?

Apart from the automatically collected data, we also process data which you voluntarily provide to us. Currently we collect the following data with the listed tools:

General contact form: first and last name, e-mail address, telephone number, company, subject and your message, so that we can contact you in case of questions or information about your request

  •     Form for seminar registration: First and last name, e-mail address, company, telephone, billing information.
  •     Newsletter registration form: your e-mail address, first and last name and salutation

Form for downloading documents: Your e-mail address so that we can send you the requested documents


We process the personal data transmitted by you (for example by contact form or e-mail) for the purpose of answering your inquiries and for conducting individual communication, as far as you wish. Which data is collected in the case of a contact form can be seen from the contact form. The legal basis for processing the data is our legitimate interest in answering your request in accordance with Art. 6 para. 1 lit. f DS-GVO. If your contact is aimed at concluding a contract, then additional legal basis for the processing is Art. 6 para. 1 lit. b DS-GVO given. Your data will be deleted after final processing of your request, provided that the deletion does not conflict with any statutory storage requirements.

Newsletter Sign up

For the newsletter dispatch we use Mailchimp as part of our contract processing contract. Mailchimp is part of “The Rocket Science Group”, which is subject to the regulations of the EU-US Privacy Shield.

A data transmission to this newsletter provider in the USA is thus carried out in accordance with the legal admissibility provisions in accordance with § 4 b BDSG (from 25.05.2018: Article 45 DS-GVO i.V.m. Art. 46 (5) p. 2 DS-GVO). The DS-GVO provides for a continuation of the adequacy decisions already issued. For the EU-US Privacy Shield, the Commission has identified the adequacy of the level of data protection (C (2016) 4176 final). The e-mail address is only saved for the purpose of sending an e-mail to the owner of the e-mail address in which he can confirm the membership in the e-mail list (“Double-Opt-In”), If the e-mail address has been confirmed, it will be permanently stored with the list provider until the e-mail address is deleted by the owner of the e-mail address or by us as the list operator.

If you have expressly consented, we will use your e-mail address and personal information to send you regularly our newsletter. For the reception of our newsletter the indication of an e-mail address is sufficient. The additional voluntary information about you serves only to personalize the newsletter. For sending the newsletter, we use the so-called double opt-in procedure. This means that we will not send you a newsletter until you have confirmed to us that you agree to the sending of the newsletter and have also activated the link in the following confirmation e-mail. By activating the confirmation link, you give us your consent to the use of your personal data in accordance with Art. 6 para. 1 lit. a DS-GVO. The data collected by us when registering for the newsletter will be used exclusively for advertising purposes in the context of the newsletter. You can unsubscribe from the newsletter at any time via the provided link in the newsletter.

Automatically stored data

When you visit our website, certain information (= log files) are automatically stored for administrative and technical reasons. These are the following: type and version of browser used, date and time of access, amount of data sent, operating system and IP address in anonymous form. The processing is carried out in accordance with Art. 6 para. 1 lit. f DS-GVO based on our legitimate interest in improving the stability and functionality of our website.

To optimize our website, we use cookies. These are small text files that are stored on your device. Some of the cookies we use are deleted after the end of the browser session, ie after closing your browser (so-called session cookies). Other cookies remain on your device and allow us or our affiliate to recognize your browser the next time you visit (long-term cookies). If cookies are set, they collect and process individual user information such as browser and location data as well as IP addresses to an individual extent.

Insofar as personal cookies are also processed by individual cookies implemented by us, the processing is carried out in accordance with Art. 6 para. 1 lit. b DS-GVO either for the execution of the contract or in accordance with Art. 6 para. 1 lit. f DS-GVO for safeguarding our legitimate interests in the best possible functionality of the website as well as a customer-friendly and effective design of the page visit.
We work with advertising partners who help us to make our website more interesting for you. For this purpose, in this case, when you visit our website, cookies from partner companies are stored on your hard disk (third-party cookies). Below you will be informed about the use of such cookies and the scope of the information collected within the following paragraphs.

Please note that you can set your browser so that you are informed about the setting of cookies and individually decide on their acceptance or can exclude the acceptance of cookies for specific cases or in general. Each browser differs in the way it manages the cookie settings. This is described in the Help menu of each browser, which explains how to change your cookie settings.

Google Analytics

This website uses Google Analytics, a web analytics service of Google LLC, 1600 Amphitheater Parkway, Mountain View, CA 94043, USA (“Google”). Google Analytics uses so-called “cookies”, text files that are stored on your computer and that allow an analysis of the use of the website by you. The information generated by the cookie about your use of this website (including your IP address) is transmitted to and stored by Google on servers in the United States.

This website uses Google Analytics exclusively with the extension “_anonymizeIp ()”, which ensures anonymization of the IP address by curtailment and excludes a direct personal reference. The extension will truncate your IP address beforehand by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be sent to a Google server in the US and shortened there. In these exceptional cases, this processing is carried out in accordance with Art. 6 para. 1 lit. f DS-GVO based on our legitimate interest in the statistical analysis of user behavior for optimization and marketing purposes. Google will use the information on our behalf to evaluate your use of the website, to compile reports on website activity for website operators and to provide other services related to website usage and internet usage. Google may also transfer this information to third parties if required by law or as far as third parties process this data on behalf of Google. Google will never associate your IP address with other data.

You can prevent the installation of cookies by setting your browser software accordingly; however, we point out that in this case you may not be able to fully use all the functions of this website. You may also prevent the collection by Google of the data generated by the cookies and related to your use of the website and the processing of this data by Google by downloading and installing the plug-in available under the following link:


Google Analytics Remarketing

Our website uses the features of Google Analytics remarketing in conjunction with the cross-device capabilities of Google AdWords and DoubleClick. Provider is the Google LLC., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA.

This feature allows the Google Analytics remarketing ad groups to be linked to the cross-device features of Google AdWords and Google DoubleClick. In this way, interest-based personalized advertising messages that have been customized based on your past usage and browsing behavior on one end device (e.g., cell phone) may also be displayed on another of your end devices (e.g., tablet or PC).

Once you have given your consent, Google will associate your web and app browsing history with your Google Account for this purpose. That way, the same personalized advertising messages can appear on any device you sign in to with your Google Account.

To support this feature, Google Analytics collects Google-authenticated IDs of users who are temporarily linked to our Google Analytics data to define and create audiences for cross-device ad promotion.

You can permanently opt out of cross-device remarketing / targeting by turning off personalized advertising in your Google Account; follow this link:

The aggregation of the collected data in your Google Account is based solely on your consent, which you can submit or revoke on Google (Article 6 (1) (a) DS-GVO). For data collection operations that are not merged into your Google Account (for example, because you do not have a Google Account or have objected to the merge), the collection of data is based on Art. 6 (1) lit. f DS-GVO. The legitimate interest results from the fact that the website operator has an interest in the anonymous analysis of website visitors for advertising purposes.

Google AdWords and Google Conversion Tracking

Our website uses the Google AdWords program. Adwords is an online advertising tool from Google LLC., 1600 Amphitheater Parkway, Mountain View, CA 94043, United States (“Google”).

We use the offer of Google Adwords to draw attention to our attractive offers with the help of advertising materials (so-called Google Adwords) on external websites. In relation to the data of the advertising campaigns, we can determine how successful the individual advertising measures are. We are interested in showing you advertisements of interest to make our website more interesting to you.

As part of Google AdWords, we use the so-called conversion tracking. When you click on an ad served by Google, a conversion tracking cookie is set. Cookies are small text files that the Internet browser stores on the user’s computer. These cookies lose their validity after 30 days and are not used for the personal identification of the users. If the user visits certain pages of this website and the cookie has not expired yet, Google and we may recognize that the user has clicked on the ad and has been redirected to this page.

Each Google AdWords customer receives a different cookie. Cookies can not be tracked through the websites of advertisers. The information gathered using the conversion cookie is used to generate conversion statistics for AdWords advertisers who have opted for conversion tracking. Customers are told the total number of users who clicked on their ad and were redirected to a conversion tracking tag page. However, they do not receive information that personally identifies users. If you do not want to participate in tracking, you can block this usage by disabling the Google Conversion Tracking cookie through its Internet browser under User Preferences. You will not be included in the conversion tracking statistics.

The storage of “conversion cookies” is based on Art. 6 para. 1 lit. f DS-GVO. The website operator has a legitimate interest in analyzing user behavior in order to optimize both its website and its advertising.

US-based Google LLC is certified under the US Privacy Shield, which ensures compliance with the level of data protection in the EU.

Please note that certain functions of this website may not be used or can only be used to a limited extent if you have deactivated the use of cookies.

Google Maps

On our website we use Google Maps (API) from Google LLC, 1600 Amphitheater Parkway, Mountain View, CA 94043, USA (“Google”). Google Maps is a web service for displaying interactive (land) maps to visually display geographic information. The use of this service will show you our location and facilitate your arrival.

As soon as you visit the sub-pages in which the map of Google Maps is integrated, information about your use of our website (such as your IP address) is transmitted to Google’s servers in the USA and stored there. This is done regardless of whether Google provides a user account that you are logged in to, or if there is no user account. When you’re logged in to Google, your data will be assigned directly to your account. If you do not wish to be associated with your profile on Google, you must log out before activating the button. Google stores your data (even for non-logged-in users) as usage profiles and evaluates them. Such an evaluation is carried out in particular according to Art. 6 para. 1 lit.f DS-GVO on the basis of the legitimate interests of Google in the display of personalized advertising, market research and / or needs-based design of its website. You have a right to object to the creation of these User Profiles, and you must be directed to YouTube to use them.

US-based Google LLC is certified under the US Privacy Shield, which ensures compliance with the level of data protection in the EU.

If you disagree with the future transmission of your data to Google when using Google Maps, you can also disable the Google Maps web service completely by turning off the JavaScript application in your browser. Google Maps and the map display on this website can not be used.
