Private Policy

The website is hosted by the Internet service provider IONOS. According to the provider, the servers are located in Europe and the USA.

The use of the website is generally possible without providing personal data. The personal data that is technically collected when using this website – as well as any other website – e.g. on the hoster’s servers, is shown in the paragraph “Server log files”.

Transmission of personal data

Personal data that users voluntarily transmit to the operator – e.g. as part of contacting the operator via the e-mail form – is forwarded to the operator in SSL-encrypted form (e-mail). Your personal data transmitted in this way will be stored for the purpose of processing the inquiry and in the event that follow-up questions arise. Your personal data will be stored and processed in accordance with the applicable data protection regulations. Your personal data will only be used to the extent and for the purpose for which you have given your consent to the operator. They will not be passed on to third parties.

Information about which of your personal data is stored by the operator and for which use you have given your consent to the operator, you will receive on request by mail or e-mail.

You can change or completely revoke your consent to the use of your personal data at any time by mail or e-mail for the future. If you revoke the use of your personal data, it will be completely deleted. A later reactivation is then no longer possible.


To make data transfer as secure as possible, this website uses SSL encryption. You can recognize it by the prefix https://…). Nevertheless, electronic communication can never be completely secure. All data and information that you access and/or transmit online can be obtained by third parties by unlawful means. We cannot accept any responsibility or liability for the disclosure of information due to errors and/or unlawful access during data transmission by third parties. You can therefore always send your messages and personal data to us by alternative means, for example by telephone or by mail.


Server log files

Each time a user accesses a page from the offer and each time a file is retrieved, the Internet service provider stores data about this process in server log files. The following data may be recorded:

the page from which the file was requested

the file name of the retrieved file

the date and time of the request

the amount of data transferred

the access status (file transferred, file not found, etc.)

the name of the web browser used

the IP address of the requesting device

the requesting provide

the operating system of the requesting device

as well as other similar information that serves to avert danger in the event of attacks on the provider’s systems.

This information is required in order to correctly deliver the contents of this website to you, to ensure the security of the information technology system and the provider’s technology, as well as to fulfill the obligation to provide law enforcement authorities with the information necessary for prosecution in the event of a cyber attack.

This data is stored on the provider’s server and is only used anonymously for statistical purposes regarding the use of the website. Conclusions about individual persons and their usage behavior are not possible. The data will not be passed on to third parties, not even in extracts. The legal obligation to check this data or to have it checked by the responsible authorities remains reserved if concrete indications of illegal use become known.

E-mail newsletter 

In order to receive the newsletter offered on our website, you can register via our form. We use the so-called double opt-in procedure. Here, a confirmation email is first sent to your specified email address, with a request for confirmation. The registration only becomes effective when you click on the activation link contained in the confirmation email. We use your data transmitted to us exclusively for sending the newsletter, which may contain information or offer.

We use mailchimp to send our newsletter. Your data will therefore be transmitted to mailchimp. In doing so, mailchimp is prohibited from using your data for purposes other than sending the newsletter. The mailchimp is not permitted to pass on or sell your data. MailchimpĀ® is a registered trademark of The Rocket Science Group.

You can revoke your consent to the storage of data and its use for newsletter dispatch at any time, e.g. via the unsubscribe link in the newsletter.


Newsletter tracking

The NADAN newsletters sent in HTML format contain so-called tracking pixels. A tracking pixel is an embedded miniature graphic that enables a log file record to be created in order to conduct statistical evaluations of the success or failure of the e-mail newsletter dispatch. For example, it is possible to check whether the e-mail newsletter was delivered, whether the e-mail address still exists actively, whether and when the e-mail newsletter was opened and which links contained in the e-mail newsletter were called up.

These personal data are also not passed on to third parties. Consent to the storage and use of personal data can be revoked at any time via a corresponding link contained in each newsletter.



To manage the cookies and similar technologies used (tracking pixels, web beacons, etc.) and related consents, we use the consent tool “Real Cookie Banner”. Details on how “Real Cookie Banner” works can be found at <a href=”” rel=”noreferrer” target=”_blank”></a>.

The legal basis for the processing of personal data in this context are Art. 6 (1) lit. c GDPR and Art. 6 (1) lit. f GDPR. Our legitimate interest is the management of the cookies and similar technologies used and the related consents.

The provision of personal data is neither contractually required nor necessary for the conclusion of a contract. You are not obliged to provide the personal data. If you do not provide the personal data, we will not be able to manage your consents.


Profiling and automated decision making
NADAN does not use any procedures for automated decision-making and/or profiling.


Independent deletion of personal data

Personal data is only stored for the period of time required to achieve the purpose of storage. If the purpose of storage no longer applies or if a legally required storage period expires, the personal data will be deleted independently.


Your rights

German and European data protection law gives you a variety of rights with regard to your personal data. In particular, you have the right to request confirmation at any time as to whether personal data relating to you is being processed, to receive information about which personal data is being stored and processed, the purposes for which the data is being used and, if possible, the planned duration for which the personal data is being stored or, if this is not possible, the criteria for determining this duration. You also have the right to request correction or deletion of the personal data concerning you, as well as to restrict its use or to object to its use altogether. You may request information about the origin of the personal data, as well as request that the personal data concerning you be handed over in a structured, common and machine-readable format. You are free to subsequently transfer this data to another responsible party. You may even request that we – insofar as this is technically feasible and insofar as this does not affect the rights and freedoms of other persons – transfer your personal data directly to another controller.

And of course you can complain to the competent supervisory authority. Berlin Commissioner for Data Protection and Freedom of Information.
