Liability for content

The content of our website has been produced with utmost care. We cannot, however, guarantee the accuracy, completeness and up-to-dateness of the content. As the service provider, we are responsible under § 7, para.1 TMG (German Telemedia Services Act) for our own content on these pages in accordance with general laws and provisions. Under §§ 8 to 10 TMG, however, as the service provider we are neither obliged to monitor information transmitted or saved from third parties nor to investigate circumstances which suggest illegal activity. This does not affect obligations under general law governing the removal or blocking the use of information. However, liability in this regard is only applicable from the time an actual violation of the law is established. Should such a violation of the law become apparent, we will immediately remove this content.

Liability for links

Our website contains links to external third-party websites over the content of which we have no control. Therefore, we are unable to assume any liability with respect to those third-party content. In any case the respective provider or operator of the websites concerned shall be responsible for the content of the linked pages. The linked pages were reviewed with regard to possible infringements at the time they were linked. No illegal content was evident at the time the link was created. However, without any specific indication of illegal activity, it is not reasonable for us to permanently monitor the content of the linked pages. However, should any such illegal activity become evident, the relevant links will be removed immediately.


The contents and works on these pages, compiled by the operators of the website, are subject to German copyright. Any duplication, editing, dissemination as well as any kind of utilisation beyond the limits of copyright must be approved in written form by the respective author or creator. Downloads and copies of this page are permitted exclusively for private, non-commercial use. Unless the content on this website was created by the operator himself, third-party copyrights shall be observed. In particular, third-party content shall be marked as such. Should you nonetheless become aware of any copyright infringement, we kindly ask you to notify us accordingly. We will immediately remove such content upon gaining knowledge of any violations of law.

Data privacy

In general our website can be used without stating any personal data. Insofar as personal data (e. g. name, address or e-mail addresses) are collected on our pages, this will always happen on a voluntary basis, wherever possible. These data will not be passed on to third parties without your explicit consent.

We would like to point out that the data transmission via internet (e. g. when communicating through e-mail) can have security flaws. A gapless data protection against third-party access is not possible.

We hereby explicitly object to the third-party use of contact data published in accordance with the editorial requirements for the mailing of not expressly solicited advertising and information materials. The website operators explicitly reserve the right to take legal action in case of unsolicited mailings of advertising information, e. g. by way of spam mails.

Field of application

This data privacy statement is to inform users about the kind, scope and purpose of the collection and utilisation of personal data by the responsible provider

Hoellstern GmbH
Gruenstrasse 13 (Gate 2)

The legal provisions of data privacy are laid down in the Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG) and the German Telemedia Services Act (Telemediengesetz, TMG).

Making contact

When making contact with the provider (for instance via contact form or e-mail), the personal user information will be stored for handling the request and also in case of follow-up questions arising.

Comments and posts

When leaving blog comments or other posts, the user IP addresses will be stored. This is done for the provider to be on the safe side, if someone should write illegal content in comments and posts (insults, forbidden political propaganda etc.). In this case the provider himself can be prosecuted for the comment or post and is therefore interested in the author’s identity.


With the newsletter we want to inform you about us and our offers.

If you wish to receive the newsletter, we need you to give us a valid e-mail address together with some information which enable us to verify that you are the owner of the stated e-mail address or that its owner agrees to the reception of the newsletter. Further data will not be collected. These data will be used only for the dispatch of the newsletter and not be disclosed to any third parties.

In the process of your newsletter registration we will store your IP address and the date of your registration. This storage shall only serve to provide evidence in case a third party should abuse an e-mail address and register for the newsletter reception unbeknown to the legitimate owner.

You can withdraw your consent to the storage of your data, the e-mail address and its utilisation for the dispatch of the newsletter at any time. The revocation can be done via a link in the actual newsletters, in your member area or by sending a note to the above contact options.

Embedding of third party services and contents

It can happen that within the frame of this online offer third party contents such as videos on YouTube, map material from Google Maps, RSS feeds or graphics from other websites are embedded. This always implies that the providers of such contents (hereinafter referred to as “third party providers“) pick up on the IP address of the users. For without the IP address they could not send the contents to the browser of the respective user. Hence the IP address is necessary for the representation of those contents. We are striving to use only such contents where the respective providers use the IP address only for the delivery of the contents. We have, however, no influence if the third party providers store the IP address e. g. for statistical purposes. Insofar as we gain knowledge about this, we will let the users know about it.

The users can influence the application of the cookies. The majority of browsers offer the possibility to restrict the storage of cookies or prevent it completely.
