We are pleased about your visit to our website and your interest in our company. The protection of your data is of the utmost importance to us. With the following notes on data protection, we would like to inform you about the purposes for which and the extent to which we collect or process your personal data when you use our websites and how we protect your privacy when you provide us with your data.



PierraaGroup GmbH is the operator of these websites and as the responsible body in the sense of Art. 4 Para. 7 DS-GVO in charge of compliance with the applicable data protection regulations.

The personal data of our users will be stored and processed by us in accordance with the relevant regulations, in particular the Basic Data Protection Regulation (DS-GVO), the Federal Data Protection Act (BDSG) and the Telecommunications Telemedia Data Protection Act (TTDSG) in their current versions. All personal data will only be collected for specified, clear and legitimate purposes and will not be kept longer than necessary.


Personal data are individual details about personal or factual circumstances of a identified or identifiable natural person (e.g. name, date of birth and contact details).



In principle, our websites can be used by you without providing your personal data. However, providing your data may be necessary for certain applications of our websites. Therefore, the use of our web pages may be restricted if you do not provide us with your data.

As soon as you visit our web pages, our web servers temporarily store each access in a log file. The following data can be recorded and stored until automatic deletion: inter alia IP address, date and time of access, transferred data volumes, messages on the success of the access to the web pages, identification data of the browser and operating system used, the website from which the access takes place and the IP address of your Internet access provider. This data is processed for the purpose of enabling the use of the websites, system security, technical administration of the network infrastructure and optimization of the Internet services. This is to be considered a legitimate interest in accordance with Art. 6 Para. 1 S. 1 lit. f DS-GVO.



We collect, store and process your personal data (e. g. first name, surname, address, e-mail address, telephone number), if a business relationship exists or is to be established, e. g. in the context of an order, as well as in the case of the contentual extension of the business relationship. In addition, we use your personal data for registration on our website as far as you have transmitted them to us and have consented to the processing of your personal data. Furthermore, we collect, store and process your personal data when you contact us by sending an e-mail, as far as this is necessary for the handling of your inquiries and correspondence. The personal data collected by us will be deleted immediately as soon as they are no longer required for this purpose, unless there are legal retention periods. The provision of your personal data is voluntary.



We use your personal data within PierraaGroup GmbH. Our external service providers, who carry out data processing on our behalf, are contractually obliged to treat personal data in accordance with the applicable regulations as defined in Art. 28 DS-GVO. As far as these companies come into contact with your personal data, we have ensured through legal, technical and organizational measures as well as through regular controls that they comply with the regulations of the data protection laws.

If you find links from other responsible organizations on our website (e. g. Google Maps, Facebook, Xing, LinkedIn, YouTube) and click on the link, you use the website directly with the respective responsible organization, so that our data protection regulations do not apply to this website.

We reserve the right to transfer your personal data to authorities entitled to receive information, if we are obliged to do so by law or by court order.
A transfer of your personal data to other third parties does not take place in principle.


On our webpages, various information is stored in so called cookies, which serve a user-friendly handling of the application and make the internet offer entirely more effective. In addition, the data stored in a cookie eliminates the need of filling out forms twice. The cookies we use are temporary and deleted regularly.

You can manage the acceptance of cookies from our websites independently in your browser and block them, if necessary. You can also delete cookies already set, at any time. Furthermore, you can inform yourself about the possibility of deactivating cookies in the settings of your selected browser. If you do not accept cookies, this may in individual cases lead to restrictions in the use of our websites. We would like to point out that after deleting your cookies you may have to reactivate any opt-out cookies that have been set.

We recommend that you regularly delete the cookies and the browser history manually.

We differ between technically necessary cookies and static and marketing cookies. Technically necessary cookies are those, which make the use of the site technically possible. Cookies, which are not technically necessary are all those, that are used for marketing and statistical purposes. PierraaGroup GmbH uses Google Analytics for this purpose.

Consent to data processing by means of cookies is voluntary and can be cancelled or adjusted at any time by clicking on the following link: Call up settings

Your consent applies to the following domains:

Flash-Cookies and HTML5 storage objects

On our website we use HTML5 storage objects, which are stored on your device. The required data is stored independently of the browser used. There is no expiry date. Processing of the HTML5 storage objects can be prevented by using the private mode in the browser used.

Flash cookies used by us are not recorded by your browser, but are processed by your Flash plug-in. When using Mozilla Firefox, the activation of Flash cookies is automatically blocked. To activate the setting of Flash cookies, your explicit consent is required when using this browser. If you do not give your consent to enable Flash cookies, they will not be activated and the website content may not be displayed correctly. When using Google Chrome and Microsoft Edge, please note that these browsers do not support the use of Flash cookies by default, as the corresponding Flash plug-in is not installed by default. Thus, if you use Google Chrome and Microsoft Edge, Flash cookies will not be set unless you manually install the Flash plug-in.

As already mentioned, it is recommended that you manually clear cookies and browser history on a regular basis.


In order to optimize the contents and offers of our websites and to collect statistical evaluations, various technical programs are used, which record data on the behavior of the user of the websites, also in anonymous form. For this purpose, for example, data on click behavior, duration of visits, system settings and origin of the users are collected in the form of text files by using analysis software cookies. Cookies are stored on your computer for these analyses. This collected data can be stored on the servers of the operators of the analysis tools. The collected data will not be used to personally identify the user and will not be merged with other personal data of the user.

You can prevent the installation of cookies by appropriately adjusting your browser settings. However, we would like to point out that in this case you may not be able to use all functions of this website to their full extent. In the following section, we present the analysis tools we use in detail.

The following analysis tools are used on our website for this purpose:

Google Analytics

If you have given your consent in the cookie notice, Google Analytics is used on our website. This is a web analysis service of Google Inc. The legal basis for the use of Google Analytics is therefore your consent in accordance with Art. 6 para. 1 sentence 1 lit. a DS-GVO.

Google Analytics uses cookies which are stored on your computer and which enable an analysis of your use of our website. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there.

Our website uses Google Analytics with the extension "_anonymizeIp". This allows IP addresses to be processed in a shortened form, thus excluding the possibility of personal references. If the data collected about you contains a personal reference, this is immediately excluded and the personal data is thereby deleted instantly. Only in exceptional cases, the full IP address is transferred to a Google server in the USA and shortened there. The IP address transmitted by your browser within the framework of Google Analytics is not merged with other Google data.  

On our behalf, Google will use this information to evaluate your use of the website, to compile reports on the website activities and to provide us with further services related to the use of the website and the internet. 

The recipient of the collected data may be Google. For the exceptional cases in which personal data is transferred to the USA, Google has subjected itself to the EU-US Privacy Shield:

The described data is automatically deleted after 14 months. Data, whose retention period has been reached is automatically deleted once a month.

You can prevent the collection of your data by Google Analytics by clicking on the following link. An opt-out cookie will be set to prevent the collection of your data during future visits to our website: Disable Google Analytics.

You can find more information about this web analytics tool at: and in the Google Privacy Policy"


Our websites use the social plug-ins of various social network providers. As soon as you visit one of our websites that contains such a plug-in, the content of the plug-in is transmitted directly to your browser. By using social plug-ins, we offer you the possibility to interact directly with our contributions via the comment function.

By clicking on the respective social media plug-in, you will be directly forwarded to our website at the corresponding social network and your data will be transmitted to the servers of the respective social network provider. These data include IP address, date and time of access, identification data of the browser and operating system used, the website from which the access takes place, etc.

We would like to point out that we have no influence on the scope of data processing by the respective provider of the social network. For the purpose, type and scope of data collection as well as the further processing and use of the data, please refer to the privacy policy of the respective provider.Please note that the servers of social network providers may be located to a large extent in countries outside the European Union. Companies that process data in countries outside the European Union are subject to data protection laws, which do not regularly guarantee the protection of personal data to the same extent as it is the case under the data protection laws of the European Union.

The following social plug-ins are offered on our websites:


We use a plug-in from Kununu on our website to visualize our Kununu rating. The provider of this plug-in is New Work SE, Dammtorstraße 30, 20354 Hamburg, Germany and is provided by them. When you call up our website, the Kununu plug-in establishes a connection to Kununu servers, which can be used to display our current Kununu rating. Kununu does not store any personal data about you when you access this website. In particular, Kununu does not store any IP address. The Kununu plug-in does not evaluate your use of our website.

Further information on data processing by the provider of the Kununu plug-in can be found at and


Google Maps

We use Google Maps API, a service of Google Inc. for the visual presentation of geographical information. The information generated by Google Maps API is usually transferred to a Google server in the USA and stored there. Google may transfer the data obtained through the use of Google Maps to third parties, if third parties process this data on behalf of Google or if this is legally permissible or prescribed. The IP address transmitted by your browser when using Google Maps will not be merged with other data from Google. Nevertheless, it would be technically potentially possible for Google to process the data received for other purposes or to identify individual users without PierraaGroup GmbH having or being able to influence this. For these reasons, the use of Google Maps is problematic in terms of data protection.

However, you have the option of preventing the transfer of data to Google by deactivating the Google Maps service by disabling the JavaScript function in your browser. In this case, however, you cannot use the map display.

By using these web pages with the JavaScript function activated, you expressly declare your consent to the processing of the data collected from you by Google Inc. in the manner and for the purposes described above, with full knowledge of the data protection issues.

Company: GOOGLE INC.,1600 Amphitheatre Parkway, Mountain View, CA 94043, USA
