1. Scope and legal basis

(1) This privacy policy explains the nature, scope and purpose of the processing of personal data within the context of our online services (website) and the associated webpages, functions and content.

(2) With regard to the terminology used, such as “personal data” and “processing”, we refer to the definitions in Article 4 of the General Data Protection Regulation (GDPR).

(3) The term “user” covers all categories of people who are the subject of data processing. These include our business partners, clients, potential clients and any other visitors to our website.

(4) The personal data of users which is processed within the context of this website includes:

  • contractual data (e.g. names and addresses of clients or potential clients),
  • contact details (e.g. email address, telephone number),
  • usage data (e.g. the pages of our website which are visited, interest in our services and products),
  • content data (e.g. information given in emails) and
  • technical data (e.g. IP addresses, device information).

(5) Users’ personal data is processed in particular for the following purposes:

  • to provide the website, its content and its functions,
  • to provide contractually agreed services,
  • to provide customer service,
  • to answer enquiries and communicate with users,
  • to carry out marketing, and
  • to maintain the website’s security.

(6) We process personal data solely in compliance with the relevant data protection provisions. This means that users’ data will only be processed when it is legally permitted to do so. This is the case in particular when the data processing is required or prescribed by law for the performance of our contractual services (e.g. for the processing of commissions and orders) and of our online services, when the user has given their consent or on the grounds of our legitimate interests. Legitimate interests include the analysis, optimisation, security and cost-effective operation of our website.

(7) Please note that the legal basis for consent is Article 6(1) Sentence 1 (a) and Article 7 GDPR; the legal basis for processing for the performance of our services and the execution of contractual provisions is Article 6(1) Sentence 1 (b) GDPR; the legal basis for processing for the performance of our legal obligations is Article 6(1) Sentence 1 (c) GDPR; and the legal basis for processing on the grounds of our legitimate interests is Article 6(1) Sentence 1 (f) GDPR.

2. Security measures

(1) 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, in accordance with Article 32 GDPR. This serves to protect the data processed by us from, in particular, accidental or intentional manipulation, loss or erasure or unauthorised access by third parties. The security measures also include the encrypted transfer of data between your browser and our server.

(2) We have also established processes which guarantee the protection of data subjects’ rights, the erasure of data and a reaction to any threats to the data.

3. Transfer of data to third parties and third-party service providers

(1) Insofar as we disclose or transfer data or otherwise make data accessible to other persons and businesses (processors or third parties) in the context of our processing work, this is only done on the basis of legal permission. This is the case, for example, if the data is transferred to third parties when this is required for performance of a contract in accordance with Article 6(1) Sentence 1 (b) GDPR, when you have given your consent, when we are legally obliged to do so or on the grounds of our legitimate interests (e.g. for use by authorised representatives, web hosts etc.). Insofar as we commission third parties with the processing of data on the basis of a “processing agreement”, this is done on the basis of Article 28 GDPR.

(2) Insofar as we process data in a third country (i.e. outside of the European Union or European Economic Area), or such processing is performed in connection with the use of third-party services or the disclosure or transfer of data to third parties, this occurs only when the particular conditions set out in Articles 44 et seq. GDPR are also met. That is, such processing will take place on the basis of particular guarantees, such as official recognition of a level of data protection corresponding to that ensured within the EU (e.g. via the Privacy Shield Framework for the USA), for example, or in compliance with special, officially recognised contractual obligations (“standard contract provisions”).

4. Collection of access data and log files

(1) We collect data concerning every instance of access to the server on which this service is located (known as server log files), on the grounds of our legitimate interests within the meaning of Article 6(1)(f) GDPR. This data is required for technical purposes, in order to display the website to you and to guarantee its stability and security. The access data includes the date and time of access, the name and URL of the file retrieved, the website from which access takes place (referrer URL), the browser used and possibly the operating system of the user’s computer as well as the name of the access provider making the request. As IP anonymisation is activated, the user’s IP address is only collected in a shortened form.

(2) The log file information is stored for a maximum of seven days, in order to evaluate the security and stability of the system, and subsequently erased. Data which must be stored for a longer period for the purposes of evidence is exempted from erasure until the incident in question has been fully resolved.

(3) We also use cookies and analytics services when you visit our website. Further details on this can be found under Sections 6 and 7 of this privacy policy.

5. Contacting us

If users contact us via email, we will process the information which they provide (email address, name, message and any other voluntarily provided data such as telephone number or address) in order to handle their enquiry, in accordance with Article 6(1) Sentence 1 (b) GDPR.

6. Cookies

(1) We use cookies for our website. Cookies are small text files that are stored on your device, assigned to the browser you use, and provide certain pieces of information to the creator of the cookie (in this case, to us). Cookies cannot run any programs or transmit viruses to your computer. They serve to make the website more user-friendly and more effective overall.

(2) Cookies are divided into transient cookies and persistent cookies. Transient cookies are automatically deleted when you close the browser. They are also known as session cookies. Session cookies store a “session ID” which can be used to associate different requests from your browser with the same session. This means that your device can be recognised if you return to the same website during a browsing session. Session cookies are deleted when you close the browser. Persistent cookies are stored on your device between browser sessions so that your interests or actions across multiple websites can be stored. Persistent cookies are automatically erased after a predetermined period. We use persistent cookies as part of our use of Google Analytics. For more information on this, please see Section 7 of this privacy policy below.

(3) You can erase cookies at any time via the security settings of your browser. You can also change your browser settings as desired, for example to reject third-party provider cookies or reject all cookies. However, please note that if you do this, you may not be able to use the full functionality of this website.

(4) You can object to the use of cookies for performance measurement via the deactivation page of the Network Advertising Initiative ( as well as via the US website or the European website

7. Google Analytics

(1) On the basis of our legitimate interests (i.e. interest in the analysis, optimisation and cost-effective operation of our website within the meaning of Article 6(1)(f) GDPR), we use Google Analytics, a web analysis service provided by Google LLC (“Google”). Google uses cookies. The information generated by cookies concerning users’ interaction with this website is usually transmitted to and stored on a Google server in the USA. Google is certified under the Privacy Shield Framework, which means that it guarantees compliance with European data protection legislation (

(2) Google will use this information on our behalf  in order to evaluate users’ interactions with our website, compile reports on website activities and provide us with other services relating to the use of this website and internet usage. Pseudonymous use profiles may be created for users on the basis of the data which is processed.

(3) We only use Google Analytics with IP anonymisation activated. This means that Google will anonymise users’ IP addresses within member states of the European Union and in other states party to the Agreement on the European Economic Area. The full IP address will only be transmitted to a Google server in the USA and shortened there in exceptional cases.

(4) The IP address transmitted by the user’s browser will not be merged with other Google data. Users can prevent cookies from being stored by changing their browser settings; they can also prevent Google from collecting and processing the data generated by the cookie relating to their use of the website by downloading and installing the browser plug-in available here:

(5) Further information on the use of data by Google, as well as the different settings available and ways to make an objection, can be found on Google’s websites:  (“How Google uses information from sites or apps that use our services”), (“Advertising”), (“Ad personalisation”).

8. Newsletter

(1) This section explains the content of our newsletter, the subscription and delivery process, the statistical evaluation used and your right to object. By subscribing to our newsletter, you consent to receive it and to the processes described here.

(2) We send email newsletters with advertising information solely with the consent of the recipients or when legally permitted. Our newsletters contain information on our products and services and on our company.

(3) Subscription to our newsletter takes the form of a double opt-in process. This means that, after you sign up, you will receive an email asking you to confirm your subscription. This confirmation is needed to prevent people from signing up with email addresses which do not belong to them. Newsletter subscriptions are recorded in order to create proof of the subscription process as required by law. This involves storing the time of subscription and of confirmation as well as the IP address used. The purpose of the process is to create proof of your subscription and to be able to resolve any incidents of misuse of your personal data. This is done on the basis of Article 6(1)(f) GDPR.

(4) The newsletter is delivered by the service provider Campaign Monitor Pty Ltd., 631 Howard St., 5th Floor, San Francisco, CA 94105, USA . You can consult the newsletter service provider’s privacy policy here: The service provider is used on the basis of our legitimate interests in accordance with Article 6(1)(f) GDPR and of a processing agreement in accordance with Article 28(3) Sentence 1 GDPR . The service provider may use your data in pseudonymised form, i.e. without any personal reference to you, in order to optimise or improve its own services, e.g. to optimise technical aspects of the delivery and display of the newsletter or for statistical purposes. However, the service provider will not contact you itself, nor will it pass on your data to third parties.

(5) To subscribe  to the newsletter, you must give your email address and your name. We store this data for the purpose of sending the newsletter and addressing you personally.

(6) The newsletters contain a “web beacon” — a single-pixel file that is retrieved by the service provider’s server when the newsletter is opened. When the web beacon is retrieved, technical information such as information on your browser and system will be collected, as well as your IP address and the time of retrieval. This information is used to make technical improvements to our services, based on the technical data or target groups and their reading behaviour, on the location from which the beacon is retrieved (which can be determined from the IP address) or on the times of access. Other statistical information which is collected includes whether and, if so, when the newsletters are opened as well as which links are clicked on. It is technically possible to associate this information with individual users. However, neither we nor our service provider have any desire to monitor individual users. Rather, this information is evaluated in order to identify our users’ reading habits and adapt our content to these or send different content according to our users’ interests. If you would like to object to the analysis of your data for statistical evaluation purposes, you have to unsubscribe from the newsletter. It is unfortunately not possible to object to this analysis without ending your subscription.

(7) The newsletter is sent and its performance is measured on the basis of consent in accordance with Article 6(1)(a) and Article 7 GDPR in conjunction with Section 7(2)(3) of the German Act Against Unfair Competition (UWG).

(8) You can withdraw your consent to receive our newsletter at any time. At the end of every newsletter, you will find a link allowing you to exercise your right to withdraw consent. If users have only subscribed to the newsletter and subsequently unsubscribed, their personal data will be erased. However, we may store deregistered email addresses for up to three years before erasing them, on the basis of our legitimate interests in accordance with Article 6(1)(f) GDPR, in order to have proof of previously given consent. This data may only be processed for the purpose of defending against potential claims.

Information on data protection, evaluation of reading behaviour and your right to withdraw consent

9. Online presence on social networks

(1) We maintain an online presence within the social networks Facebook, Pinterest and Instagram in order to communicate with our clients and potential clients as well as to present our products and services.

(2) As the providers of these social networks are headquartered in the USA, users’ data may be processed outside of the European Union, which can create risks affecting, for example, the enforcement of users’ rights. However, the abovementioned social network providers are certified under the Privacy Shield Framework ( and are therefore obliged to uphold the European Union’s data protection standards.

(3) Users’ data may be processed for analysis and marketing purposes via our online presence on the social networks named. User behaviour and the interests that this reveals can be used to create anonymous user profiles, which are then used, for example, to display advertisements within and outside of the social networks that correspond to users’ probable interests. This is generally done using cookies, which are stored on users’ devices and contain information on users’ behaviour and interests. Device-independent data may also be stored in the user profiles. This applies in particular to users who are members of the social network in question and are logged into their account.

(5) We maintain an online presence on the social networks named, and process data in connection with this social media presence, on the basis of our legitimate interests (in providing interesting information outside of our website and in having additional channels for communication with our clients and potential clients) in accordance with Article 6(1) Sentence 1 (f) GDPR. If a provider asks you to consent to data processing, the legal basis for this processing is Article 6(1) Sentence 1 (a) in conjunction with Article 7 GDPR.

(5) For detailed information on the processing operations in question and users’ options for objecting (opting out), we refer to the information published by the relevant providers, which is linked below. Users can also follow these links in order to request information (right of access) and assert their data protection rights, as the providers have access to users’ data and can implement the necessary measures and provide information on this data. Should users nonetheless require our assistance, they can contact us using the contact information given at the beginning of this privacy policy.

(2) These fonts are integrated as a result of server access at Google (generally in the USA). This always requires Google to recognise the IP address of users, since the contents cannot be sent to the browser without the IP address. The IP address is therefore required for the presentation of these contents.

11. Use of Google Maps

(1) On our website, on the basis of our legitimate interest (i.e. interest in the optimisation and economic management of our website within the meaning of article 6(1)(f) GDPR), we employ Google Maps from Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA, (“Google”).

12. Your rights

(1) Users have the right to obtain information about how we process their personal data upon request and free of charge.

(2) Additionally, users have the right to rectification of inaccurate data, restriction of processing und erasure of their personal data, the right to data portability, if applicable, and, in the case of assumed unlawful data processing, the right to file a complaint with a supervisory authority.

(3) Likewise, users can revoke consent for future cases.

13. Erasure of data

Data stored by us will be erased if it is no longer required for its intended purpose and if its storage is no longer legally required. Provided that the users’ data is not erased because it is required for other legally admissible purposes, its processing will be limited. In this case, access to the data will be blocked and it will not be processed for other purposes. This applies, for instance, to user data that must be stored for reasons of commercial or fiscal law. The storage period for commercial and business letters, for instance, is 6 years according to section 257(1) of the German Commercial Code (HGB).

14. Right to object

Users can object to future processing of their personal data at any time in accordance with legal standards. Objection can be made in particular to data processing for the purposes of direct marketing.
