Relevant legal bases
The following provides an overview of the legal bases of the GDPR on which we process personal data. Please note that in addition to the provisions of the GDPR, national data protection regulations may apply in your or our country of residence or domicile. Furthermore, if more specific legal bases are applicable in individual cases, we will inform you about them in the privacy policy.

  • Consent (Art. 6(1)(a) GDPR) – The data subject has given consent to the processing of their personal data for one or more specific purposes.
  • Performance of a contract and pre-contractual inquiries (Art. 6(1)(b) GDPR) – Processing is necessary for the performance of a contract to which the data subject is party or in order to take steps at the request of the data subject prior to entering into a contract.
  • Legitimate interests (Art. 6(1)(f) GDPR) – Processing is necessary for the purposes of the legitimate interests pursued by the controller or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data.

National data protection regulations in Germany: In addition to the data protection regulations of the GDPR, national data protection regulations apply in Germany. This includes, in particular, the Federal Data Protection Act (Bundesdatenschutzgesetz – BDSG). The BDSG contains special provisions, in particular, on the right to access, the right to erase, the right to object, the processing of special categories of personal data, processing for other purposes, and transmission as well as automated decision-making in individual cases, including profiling. Furthermore, it regulates data processing for the purposes of employment (Section 26 BDSG), in particular with regard to the establishment, performance, or termination of employment relationships and the consent of employees. In addition, data protection laws of the individual German states may apply.
Security measures

We take appropriate technical and organizational measures, in accordance with legal requirements and taking into account the state of the art, implementation costs, the nature, scope, context, and purposes of processing as well as the varying likelihood and severity of the risk to the rights and freedoms of natural persons, to ensure a level of security appropriate to the risk.

These measures include, in particular, ensuring the confidentiality, integrity, and availability of data by controlling physical and electronic access to the data as well as access, input, disclosure, availability, and separation. We have also established procedures to ensure the exercise of data subject rights, deletion of data, and responses to data breaches. Furthermore, we take into account the protection of personal data in the development or selection of hardware, software, and procedures in accordance with the principle of data protection, by design and default.

SSL encryption (https): To protect your data transmitted via our online services, we use SSL encryption. You can recognize such encrypted connections by the prefix https:// in the address line of your browser.

Transfer of personal data

In the course of our processing of personal data, it may happen that the data is transferred to other places, companies, legally independent organizational units or persons or disclosed to them. Recipients of such data may include service providers or providers of services and content that are integrated into a website and perform IT tasks. In such cases, we comply with legal requirements and, in particular, conclude appropriate contracts or agreements with the recipients of your data that serve to protect your data.

Data transfer within the organization: We may transfer personal data to other parts of our organization or grant them access to such data. If this transfer is for administrative purposes, the transfer of the data is based on our legitimate business and economic interests, or if it is necessary for the fulfillment of our contractual obligations, or if there is consent from the data subjects or a legal permission.

Datenverarbeitung in Drittländern

Sofern wir Daten in einem Drittland (d.h., außerhalb der Europäischen Union (EU), des Europäischen Wirtschaftsraums (EWR)) verarbeiten oder die Verarbeitung im Rahmen der Inanspruchnahme von Diensten Dritter oder der Offenlegung bzw. Übermittlung von Daten an andere Personen, Stellen oder Unternehmen stattfindet, erfolgt dies nur im Einklang mit den gesetzlichen Vorgaben.

Vorbehaltlich ausdrücklicher Einwilligung oder vertraglich oder gesetzlich erforderlicher Übermittlung verarbeiten oder lassen wir die Daten nur in Drittländern mit einem anerkannten Datenschutzniveau, vertraglichen Verpflichtung durch sogenannte Standardschutzklauseln der EU-Kommission, beim Vorliegen von Zertifizierungen oder verbindlicher internen Datenschutzvorschriften verarbeiten (Art. 44 bis 49 DSGVO, Informationsseite der EU-Kommission:

Data Deletion

The data we process will be deleted in accordance with legal requirements as soon as their processing permissions are revoked or other permissions are no longer valid (e.g. if the purpose of processing such data no longer exists or they are not necessary for the purpose).

If the data is not deleted because it is required for other legally permissible purposes, its processing will be limited to those purposes. This means that the data will be blocked and not processed for other purposes. This applies, for example, to data that must be kept for commercial or tax reasons or whose storage is necessary for the assertion, exercise, or defense of legal claims or for the protection of the rights of another natural or legal person.

Our data protection information may also contain further information on the storage and deletion of data that applies primarily to the respective processing.

Use of Cookies

Cookies are text files that contain data from visited websites or domains and are stored by a browser on the user’s computer. A cookie primarily serves to store information about a user during or after their visit within an online offering. The stored information may include, for example, language settings on a webpage, login status, a shopping cart, or the position where a video was watched. We also include other technologies that fulfill the same functions as cookies (e.g. when user data is stored based on pseudonymous online identifiers, also referred to as “user IDs”).

The following types of cookies and functions are distinguished:

  • Temporary cookies (also known as session cookies): Temporary cookies are deleted at the latest after a user has left an online service and closed his browser.
  • Permanent cookies: Permanent cookies remain stored even after closing the browser. For example, the login status can be saved or preferred content can be displayed directly when the user visits a website again. Similarly, the interests of users that are used for measuring reach or marketing purposes can be stored in such a cookie.
  • First-party cookies: First-party cookies are set by ourselves.
  • Third-party cookies (also known as third-party cookies): Third-party cookies are mainly used by advertisers (so-called third parties) to process user information.
  • Necessary (also known as essential or absolutely necessary) cookies: Cookies can be absolutely necessary for the operation of a website (e.g. to save logins or other user inputs or for security reasons).
  • Statistics, marketing and personalization cookies: Cookies are usually also used as part of reach measurement and when a user’s interests or behavior (e.g. viewing certain content, using functions, etc.) are stored in a user profile on individual websites. Such profiles are used, for example, to display content to users that corresponds to their potential interests. This process is also referred to as “tracking,” i.e., tracking the potential interests of users. If we use cookies or tracking technologies, we will inform you separately in our privacy policy or as part of obtaining consent.

Notes on legal bases: The legal basis on which we process your personal data using cookies depends on whether we ask you for consent. If this is the case and you consent to the use of cookies, the legal basis for processing your data is the declared consent. Otherwise, the data processed using cookies will be processed on the basis of our legitimate interests (e.g. in the operation of a business-oriented online offering and its improvement) or, if the use of cookies is necessary, to fulfill our contractual obligations.
Storage duration: Unless we provide you with explicit information about the storage duration of permanent cookies (e.g. as part of a so-called cookie opt-in), please assume that the storage duration can be up to two years.

General information on revocation and objection (opt-out): Depending on whether the processing is based on consent or legal permission, you have the option to revoke your consent or object to the processing of your data through cookie technologies at any time (collectively referred to as “opt-out”). You can initially declare your objection by adjusting your browser settings, for example, by disabling the use of cookies (which may also restrict the functionality of our online offering). Objection to the use of cookies for online marketing purposes can also be declared through various services, especially in the case of tracking, via the websites and Additionally, you can obtain further information on objection within the scope of the information provided on the service providers and cookies used.

Processing of cookie data based on consent: We use a procedure for cookie consent management in which users’ consents to the use of cookies, as well as the processing and providers mentioned within the cookie consent management procedure, can be obtained, managed, and revoked by the users. The consent declaration is stored in order to avoid repeated queries and to provide evidence of consent in accordance with legal obligations. Storage can be done server-side and/or in a cookie (referred to as an opt-in cookie or similar technologies) to assign the consent to a user or their device. Subject to individual information provided by the providers of cookie management services, the following information applies: The duration of consent storage can be up to two years. In this context, a pseudonymous user identifier is generated and stored along with the time of consent, information on the scope of consent (e.g. which categories of cookies and/or service providers), as well as the browser, system, and device used.

  • Processed types of data: Usage data (e.g. visited web pages, interest in content, access times), meta/communication data (e.g. device information, IP addresses).
  • Affected individuals: Users (e.g. website visitors, users of online services).
  • Legal basis: Consent (Art. 6 para. 1 sentence 1 lit. a GDPR), Legitimate Interests (Art. 6 para. 1 sentence 1 lit. f. GDPR).

Provision of online services and web hosting
In order to provide our online services safely and efficiently, we use the services of one or more web hosting providers, from whose servers (or servers managed by them) our online services can be accessed. For these purposes, we may use infrastructure and platform services, computing capacity, storage space and database services, as well as security services and technical maintenance services.

The data processed in the context of the provision of the hosting service may include all information relating to the users of our online services that arises in the course of use and communication. This regularly includes the IP address, which is necessary to deliver the content of online services to browsers, and all inputs made within our online services or on websites.

Collection of access data and log files: We ourselves (or our web hosting provider) collect data on every access to the server (so-called server log files). The server log files may include the address and name of the web pages and files accessed, date and time of access, transferred data volumes, message about successful access, browser type and version, the user’s operating system, referrer URL (the previously visited page) and usually IP addresses and the requesting provider.

“The server log files can be used for security purposes, for example, to avoid server overload (especially in the case of abusive attacks, so-called DDoS attacks) and, on the other hand, to ensure the server’s utilization and stability.

  • Processed data types: Content data (e.g. entries in online forms), usage data (e.g. visited web pages, interest in content, access times), meta/communication data (e.g. device information, IP addresses).
  • Persons affected: Users (e.g. website visitors, users of online services).
  • Purposes of processing: Provision of our online offer and user-friendliness, provision of contractual services and customer service.
  • Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f. GDPR).
