IV. Purpose of Data Processing

1. In connection solely with use of the website, we only ever process the personal data of our users where this is necessary in order to provide a functional website and our content and services. 

2. Where contractual services are provided, we process personal data (e.g. name and address, along with users' contact details) and contract data (e.g. services used, name of contact person, payment information) for the purpose of fulfilling our contractual obligations and providing our services pursuant to Art. 6(1)(b) GDPR. The input fields marked as mandatory in online forms are required for conclusion of the contract.

As part of the provision of our online services, we store IP addresses and the time of the respective user action. This is done on the basis of our legitimate interests, as well as those of the user with regard to protection against misuse and other unauthorised use. As a general principle, this data is not passed on to third parties unless this is necessary for the pursuit of our claims or there is a legal obligation to do so in accordance with Art. 6(1)(c) GDPR.

Data shall be erased after the statutory obligations or similar have elapsed. The necessity of storing the data shall be examined every three years. Where legal archiving obligations exist, the data shall be erased after these have expired (usually after 10 years). Any information entered into a customer account shall remain until it is deleted.

Where processing is necessary for the performance of a contract to which the data subject is party, Art. 6(1)(b) GDPR is the legal basis. This also applies to data processing operations that are necessary in order to take steps prior to entering into a contract

Where the processing of personal data is necessary for compliance with a legal obligation to which our company is subject, Art. 6(1)(c) GDPR is the legal basis.

VI. Security, Order Processing, Transmission to Other Countries

1. Security Measures

In accordance with Art. 32 GDPR and taking into account the state of the art, the costs of implementation and the nature, scope, context and purposes of processing as well as the risk of varying likelihood and severity for the rights and freedoms of natural persons, we implement appropriate technical and organisational measures to ensure a level of security appropriate to the risk. These measures include, in particular, ensuring the confidentiality, integrity and availability of data by monitoring physical access to the data, as well as any access that affects it, the inputting and passing on of data, the ensuring of availability and the separation of data. Furthermore, we have established procedures that ensure the upholding of the rights of data subjects, the erasure of data and a response to threats and risks concerning data. We also take the protection of personal data into consideration right from the development stage and in the selection of hardware, software and methods in accordance with the principle of data protection by technical design and privacy-aware default settings (Art. 25 GDPR).

The security measures include, in particular, encrypted data transfer between your browser and our server.

2. Cooperation With Processors and Third Parties

Where we disclose data to other persons and companies (processors or third parties), transmit data to them or grant them access to the data in another manner as part of our processing activities, this is done only on the basis of legal permission (e.g. where transmission of data to a third party such as a payment processor pursuant to Art. 6(1)(b) GDPR is necessary for the performance of a contract), if you have given your consent, if there is a legal obligation to do so, or on the basis of our legitimate interests (e.g. the use of data protection officers, web hosts etc.).

Where we instruct third parties to process data on the basis of a 'processing agreement', this is done on the basis of Art. 28 GDPR.

3. Transmission to Third Countries

Where we process data in a third country (i.e. outside the European Union (EU) or the European Economic Area (EEA)), or where this is done in connection with the use of third-party services or the disclosure or transmission of data to third parties, this is done only if it is necessary in order to take steps prior to entering into a contract, on the basis of your consent, on the basis of a legal obligation or on the basis of our legitimate interests.

VII. Rights of the Data Subject

If your personal data is processed, you are a data subject within the meaning of the GDPR and you have the right to the following from the data controller:

1. Right of Access

You have the right to obtain from the controller confirmation as to whether or not personal data concerning you is being processed by us. Where that is the case, you may request the following information from the data controller:

a) the purposes of the processing;
b) the categories of personal data concerned

f) the right to lodge a complaint with a supervisory authority;
g) where the personal data is not collected from the data subject, any available information as to its source;
h) the existence of automated decision-making, including profiling, referred to in Article 22(1) and (4) GDPR and, at least in those cases, meaningful information about the logic involved, as well as the significance and the envisaged consequences of such processing for the data subject.

You have the right to request information on whether personal data concerning you is transmitted to a third country or an international organisation. In connection with this, you have the right to be informed of the appropriate safeguards pursuant to Article 46 GDPR relating to the transfer.

2. Right to Rectification

You have the right to obtain from the controller the rectification and/or completion of inaccurate or incomplete personal data concerning you. The data controller must carry out this rectification without undue delay.

3. Right to Restriction of Processing

You have the right to request restriction of processing of personal data concerning you where one of the following applies:

b) the processing is unlawful and you oppose the erasure of the personal data and request the restriction of its use instead;

d) you have objected to processing pursuant to Article 21(1) GDPR pending the verification whether the legitimate grounds of the controller override yours.

Where processing of personal data concerning you has been restricted, such personal data shall, with the exception of storage, only be processed with your consent or for the establishment, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or of a Member State. Where the processing of personal data has been restricted in accordance with the above-mentioned conditions, you shall be informed by the controller before the restriction of processing is lifted.

You have the right to obtain from the controller the erasure of personal data concerning you without undue delay, and the controller has the obligation to erase this data without undue delay where one of the following grounds applies:

a) the personal data is no longer necessary in relation to the purposes for which it was collected or otherwise processed;

c) for reasons of public interest in the area of public health in accordance with points (h) and (i) of Article 9(2) as well as Article 9(3) GDPR;
d) for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) GDPR in so far as the right referred to in section a) is likely to render impossible or seriously impair the achievement of the objectives of that processing; or

You have the right to object, on grounds relating to your particular situation, at any time to processing of personal data concerning you which is based on point (e) or (f) of Article 6(1) GDPR, including profiling based on those provisions.

The controller shall no longer process the personal data concerning you unless the controller demonstrates compelling legitimate grounds for the processing which override your interests, rights and freedoms or for the establishment, exercise or defence of legal claims.

Where personal data concerning you is processed for direct marketing purposes, you have the right to object at any time to processing of personal data concerning you for such marketing, which includes profiling to the extent that it is related to such direct marketing. If you object to processing for direct marketing purposes, the personal data concerning you shall no longer be processed for such purposes.

7. Right to Withdraw Consent Under Data Protection Law

You have the right to withdraw your declaration of consent under data protection law at any time. The withdrawal of consent shall not affect the lawfulness of processing based on consent before its withdrawal.

VIII. Cookies

'Cookies' are small files that are stored on users' computers. Various pieces of information can be stored within the cookies. A cookie primarily serves to save information about a user (or about the device on which the cookie is stored) during as well as after their visit within an online offering. Temporary cookies, also known as 'session cookies' or 'transient cookies', are deleted when a user leaves an online offering and closes their browser. Such a cookie may contain e.g. the contents of a shopping basket in an online shop, or a login status. 'Permanent' or 'persistent' cookies are saved even after the browser is closed. For instance, the login status may be saved if the user visits the online offering again after several days. Such a cookie may also contain the user's interests, which are used for measuring reach or for marketing purposes. 'Third-party cookies' are those that are offered by providers other than the data controller that manages the online offering (cookies belonging only to the latter are called 'first-party cookies').

We may use temporary and permanent cookies; where we do this, it is for the purpose of our legitimate interests (Art. 6(1)(f) GDPR).

If a user does not want cookies to be stored on their computer, they should disable the relevant option in their browser settings. Stored cookies can be deleted in the browser settings. Rejecting cookies may impair the correct functioning of this online content.

IX. Contact

When a user makes contact with us (via contact form or e-mail), their information will be processed for the purpose of processing and handling the contact request in accordance with Art. 6(1)(b) GDPR.

X. Erasure of Data

The data processed by us shall be erased or its processing restricted pursuant to Art. 17 and 18 GDPR. Unless explicitly specified otherwise in this Privacy Policy, the data stored with us shall be deleted as soon as it is no longer needed for its intended use and erasure of the data does not violate any statutory retention obligations. If the data is not erased because it is needed for other, legally permitted purposes, its processing shall be restricted. This means that the data shall be blocked and shall not be processed for other purposes. This applies, for instance, to data that must be retained under commercial or tax law. The retention period of the data is based on the legal requirements of the country in which the data are collected, processed, managed and stored.

Log file information shall be saved for a maximum of seven days for security reasons (e.g. for clarifying cases of misuse or fraud), after which it shall be erased. Data that must be retained for evidence purposes is excluded from erasure until final clarification of the incident in question has been obtained.

We erase e-mail enquiries and contact requests via our website within an appropriate period following which the conclusion of a contract or the like is no longer to be expected.

XI. YouTube

Our website uses the provider YouTube LLC, 901, Cherry Avenue, San Bruno, CA 94066, USA, represented by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA, for embedding videos. Normally, when you open a page containing embedded videos, your IP address is sent to YouTube and cookies are installed on your computer. However, we have embedded our YouTube videos in privacy-enhanced mode (in this case, YouTube still makes contact with the DoubleClick service from Google, but no personal data is evaluated according to Google's Privacy Policy). As a result, YouTube no longer stores any information on visitors unless they watch the video. If you click on the video, your IP address will be sent to YouTube and YouTube will know that you have watched the video. If you are logged in to YouTube, this information will also be linked to your user account (you can prevent this by logging out of YouTube before watching the video). We have no knowledge of or influence over the possible ensuing collection and use of your data by YouTube. You can find more information in YouTube's privacy policy at and can opt out at:

XII. Google Maps

We use maps from the service 'Google Maps' provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. The data processed may include, in particular, IP addresses and location data of users. However, this is not collected without their consent (which is usually obtained via the settings on users' mobile devices). The data may be processed in the USA.

XII. Google Analytics

This website uses the service 'Google Analytics', which is offered by Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA), for the purpose of analysing the use of the website by users. This service uses cookies (see VIII. Cookies). The information collected using these cookies is usually sent to a Google server in the USA and stored there.

This website uses IP anonymisation. User IP addresses are truncated within the Member States of the EU and the European Economic Area. This prevents you from being identified via your IP address. As part of the data processing agreement concluded by the website operators with Google Inc., the latter uses the information collected to prepare an evaluation of the website use and activity and provides services related to Internet use.

You can refuse to allow cookies to be stored on your device by configuring the relevant settings in your browser. If your browser does not permit any cookies, there is no guarantee that you will be able to use all functions of this website without restrictions.

You can also use a browser plugin to prevent information collected by cookies (including your IP address) from being sent to and used by Google Inc. You can find this plugin at the following link:
