Web analysis Matomo (formerly Piwik)

This website uses the open source web analysis service Matomo. Matomo uses technologies that enable cross-site recognition of the user to analyze user behavior (e.g. cookies or device fingerprinting). The information collected by Matomo about the use of this website is stored on our server. The IP address is anonymized before it is saved.

With the help of Matomo we are able to collect and analyze data about the use of our website by website visitors. This enables us to find out, among other things, when which page views were made and from which region they come. We also record various log files (e.g. IP address, referrer, browser and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks).

This analysis tool is used on the basis of Art. 6 Para. 1 lit. f GDPR. The website operator has a legitimate interest in the anonymized analysis of user behavior in order to optimize both its website and its advertising. If a corresponding consent has been requested (e.g. consent to the storage of cookies), the processing takes place exclusively on the basis of Art. 6 Para. 1 lit. a GDPR; the consent can be revoked at any time.

Deployment and use of Google AdWords

The person responsible for processing has integrated Google AdWords on this website. Google AdWords is an internet advertising service that allows advertisers to place advertisements in Google's search engine results as well as in the Google advertising network. Google AdWords enables an advertiser to define certain keywords in advance by means of which an advertisement is only displayed in Google's search engine results if the user calls up a keyword-relevant search result with the search engine. In the Google advertising network, the ads are distributed to topic-related websites using an automatic algorithm and taking into account the previously defined keywords.

The operating company for the services of Google AdWords is Google Inc., 1600 Amphitheater Pkwy, Mountain View, CA 94043-1351, USA.

The purpose of Google AdWords is to advertise our website by displaying interest-relevant advertising on the websites of third-party companies and in the search engine results of the Google search engine and by displaying third-party advertising on our website.

If a person concerned reaches our website via a Google ad, a so-called conversion cookie is stored on the information technology system of the person concerned by Google. What cookies are has already been explained above. A conversion cookie loses its validity after thirty days and is not used to identify the person concerned. If the cookie has not yet expired, the conversion cookie is used to determine whether certain sub-pages, for example the shopping cart from an online shop system, have been accessed on our website. The conversion cookie enables both we and Google to understand whether a person concerned who came to our website via an AdWords ad generated sales, i.e. completed or canceled a purchase.

The data and information collected through the use of the conversion cookie are used by Google to create visit statistics for our website. These visit statistics are in turn used by us to determine the total number of users who were referred to us via AdWords advertisements, i.e. to determine the success or failure of the respective AdWords advertisement and to optimize our AdWords advertisements for the future . Neither our company nor other Google AdWords advertisers receive information from Google that could identify the person concerned.

The conversion cookie is used to store personal information, such as the websites visited by the person concerned. Each time you visit our website, personal data, including the IP address of the Internet connection used by the person concerned, is transmitted to Google in the United States of America. These personal data are stored by Google in the United States of America. Google may pass this personal data collected through the technical process on to third parties.

The person concerned can prevent the setting of cookies by our website, as already shown above, at any time by means of a corresponding setting of the Internet browser used and thus permanently object to the setting of cookies. Such a setting of the internet browser used would also prevent Google from setting a conversion cookie on the information technology system of the person concerned. In addition, a cookie already set by Google AdWords can be deleted at any time via the Internet browser or other software programs.

Furthermore, the data subject has the opportunity to object to Google's interest-based advertising. To do this, the person concerned must access the link from each of the Internet browsers they use and make the desired settings there.

Social plugins:

Our website contains references (links) to external social networks such as Facebook, Google+, Instagram and YouTube. The functions assigned to the links, in particular the transmission of information and user data, are not already activated by visiting our websites, but only by clicking on the links. After clicking on these links, the plugins of the corresponding networks are activated and your browser establishes a direct connection to their servers.

If you click on the links while visiting our website, your user data may be transmitted to the relevant network and processed by the network. If you click on the links while visiting our website and are logged into the network at the same time via your personal user account (account), the information that you have visited our website can be forwarded to the network and stored there in connection with your account. In order to prevent an assignment to your account with the corresponding network, you must log out of your account before clicking on the link.

The purpose and scope of the data collection by the social networks and the further processing and use of your data there as well as your rights in this regard and setting options for protecting your privacy can be found in the data protection information of the relevant network. The respective social network is solely responsible for the data processing that starts when the link is clicked.

WhatsApp Business

We use the WhatsApp instant messaging service to communicate with our customers and other third parties. The provider is WhatsApp Ireland Limited, 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland.
We use WhatsApp in the “WhatsApp Business” variant.
If you contact us via the WhatsApp messenger service, you will automatically transmit your mobile number to us. This will not be assigned to your customer data and will not be used for further contact by N&H Technology GmbH. Furthermore, we do not store this data longer than necessary.

Legal declarations (such as offers, contracts or contract changes) are not made via WhatsApp and cannot be accepted.
For such inquiries, please use our official contact channels:

Customer Service:


We use the WhatsApp Business App on a dedicated mobile device. We have set up our WhatsApp accounts so that there is no automatic data synchronization with the address book. We also do not store your mobile number in the address book. Also, no cloud backups of the conversations are created.

Communication takes place via end-to-end encryption (peer-to-peer), which prevents WhatsApp or other third parties from gaining access to the communication content. However, WhatsApp receives access to metadata that is created in the course of the communication process (e.g. sender, recipient and time). We would also like to point out that WhatsApp, according to its own statements, shares personal data of its users with its US-based parent company Facebook. For more details on data processing, see WhatsApp's privacy policy at:
WhatsApp is used on the basis of our legitimate interest in communicating with customers, prospects and other business and contractual partners as quickly and effectively as possible (Art. 6 Para. 1 lit. f GDPR). If a corresponding consent was requested, the data processing takes place exclusively on the basis of the consent; this can be revoked at any time with effect for the future.
Your data will always be used only to answer your request via WhatsApp. A disclosure to third parties does not occur.

The communication content exchanged between and on WhatsApp remains with us until you ask us to delete it, revoke your consent to storage or the purpose for data storage no longer applies (e.g. after your request has been processed). After the end of the communication, the chat histories will be deleted on our part. If the communication takes place due to a communication breakdown on your part and we hear nothing from you 14 days after our last message, the message history with all data will also be deleted. Mandatory legal provisions - in particular retention periods - remain unaffected.

Data transmission to the US is based on the Standard Contractual Clauses (SCC) of the European Commission. Details can be found here:
