Relevant legal bases

Relevant legal bases according to the GDPR: In the following, you will find an overview of the legal basis of the GDPR on which we base the processing of personal data. Please note that in addition to the provisions of the GDPR, national data protection provisions of your or our country of residence or domicile may apply. If, in addition, more specific legal bases are applicable in individual cases, we will inform you of these in the data protection declaration.

  • Consent (Article 6 (1) (a) GDPR) - The data subject has given consent to the processing of his or her personal data for one or more specific purposes.
  • Legitimate Interests (Article 6 (1) (f) GDPR) - the processing is necessary for the protection of the legitimate interests of the controller or a third party, provided that the interests, fundamental rights, and freedoms of the data subject, which require the protection of personal data, do not prevail.

National data protection regulations in Germany: In addition to the data protection regulations of the GDPR, national regulations apply to data protection in Germany. This includes in particular the Federal Data Protection Act (BDSG). In particular, the BDSG contains special provisions 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 individual decision-making, including profiling. Furthermore, data protection laws of the individual federal states may apply.

Relevant legal basis according to the Swiss Data Protection Act: We process your personal data in accordance with the Swiss Federal Act on Data Protection (“Swiss DPA”). Personal data must be processed lawfully, in good faith and proportionately (Art. 6 para. 1 and 2 Swiss DPA). It may only be collected for a specific purpose that is recognisable to the data subject and may only be processed in a manner compatible with that purpose (Art. 6 para. 3 FADP). Unlike the GDPR, the Swiss DPA does not generally require private controllers to base processing on a specific legal basis from a statutory list. Therefore, there is generally no obligation to state such a legal basis for each processing activity in the privacy policy.

Reference to the applicability of the GDPR and the Swiss DPA: This privacy policy is intended to provide information in accordance with both the Swiss Federal Act on Data Protection (FADP) and the General Data Protection Regulation (GDPR). Where references are made to concepts such as the processing of personal data, legitimate interests, or special categories of data, these references are to be understood in accordance with the applicable data protection laws. Within the scope of application of the Swiss FADP, the legal interpretation of these terms is determined exclusively by Swiss law.

Security Precautions

We take appropriate technical and organisational measures in accordance with the legal requirements, 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, in order to ensure a level of security appropriate to the risk.

The measures include, in particular, safeguarding the confidentiality, integrity and availability of data by controlling physical and electronic access to the data as well as access to, input, transmission, securing and separation of the data. In addition, we have established procedures to ensure that data subjects' rights are respected, that data is erased, and that we are prepared to respond to data threats rapidly. Furthermore, we take the protection of personal data into account as early as the development or selection of hardware, software and service providers, in accordance with the principle of privacy by design and privacy by default.

Securing online connections through TLS/SSL encryption technology (HTTPS): To protect the data of users transmitted via our online services from unauthorized access, we employ TLS/SSL encryption technology. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are the cornerstones of secure data transmission on the internet. These technologies encrypt the information that is transferred between the website or app and the user's browser (or between two servers), thereby safeguarding the data from unauthorized access. TLS, as the more advanced and secure version of SSL, ensures that all data transmissions conform to the highest security standards. When a website is secured with an SSL/TLS certificate, this is indicated by the display of HTTPS in the URL. This serves as an indicator to users that their data is being securely and encryptedly transmitted.

Transmission of Personal Data

In the course of processing personal data, it may happen that this data is transmitted to or disclosed to other entities, companies, legally independent organizational units, or individuals. Recipients of this data may include service providers tasked with IT duties or providers of services and content that are integrated into a website. In such cases, we observe the legal requirements and particularly conclude relevant contracts or agreements that serve to protect your data with the recipients of your data.

General Information on Data Retention and Deletion

We delete personal data that we process in accordance with legal regulations as soon as the underlying consents are revoked or no further legal bases for processing exist. This applies to cases where the original purpose of processing is no longer applicable or the data is no longer needed. Exceptions to this rule exist if statutory obligations or special interests require a longer retention or archiving of the data.

In particular, data that must be retained for commercial or tax law reasons, or whose storage is necessary for legal prosecution or protection of the rights of other natural or legal persons, must be archived accordingly.

Our privacy notices contain additional information on the retention and deletion of data specifically applicable to certain processing processes.

In cases where multiple retention periods or deletion deadlines for a date are specified, the longest period always prevails.

Data that is no longer stored for its originally intended purpose but due to legal requirements or other reasons are processed exclusively for the reasons justifying their retention.

Data Retention and Deletion: The following general deadlines apply for the retention and archiving according to German law:

  • 10 Years - Fiscal Code/Commercial Code - Retention period for books and records, annual financial statements, inventories, management reports, opening balance sheet as well as the necessary work instructions and other organisational documents (Section 147 Paragraph 1 No. 1 in conjunction with Paragraph 3 of the German General Tax Code (AO), Section 257 Paragraph 1 No. 1 in conjunction with Paragraph 4 of the German Commercial Code (HGB)).

  • 3 Years - Data required to consider potential warranty and compensation claims or similar contractual claims and rights, as well as to process related inquiries, based on previous business experiences and common industry practices, will be stored for the duration of the regular statutory limitation period of three years. This period begins at the end of the year in which the relevant contractual transaction took place or the contractual relationship ended in the case of ongoing contracts (Sections 195, 199 of the German Civil Code).

Data Retention and Deletion: The following general retention and archiving periods apply under Swiss law:

  • 10 years - Retention period for books and records, annual financial statements, inventories, management reports, opening balances, accounting vouchers and invoices, as well as all necessary working instructions and other organizational documents (Article 958f of the Swiss Code of Obligations (OR)).
  • 10 years - Data necessary to consider potential claims for damages or similar contractual claims and rights, as well as for the processing of related inquiries based on previous business experiences and usual industry practices, will be stored for the statutory limitation period of ten years, unless a shorter period of five years is applicable, which is relevant in certain cases (Articles 127, 130 OR). Claims for rent, lease, and interest on capital, as well as other periodic services, for the delivery of food, for board and lodging, for innkeeper debts, as well as for craftsmanship, small-scale sales of goods, medical care, professional services by lawyers, legal agents, procurators, and notaries, and from the employment relationship of employees, expire after five years (Article 128 OR).

Web Analysis, Monitoring and Optimization

Web analytics (also referred to as "reach measurement") is used to evaluate the visitor flows of our online services and may include pseudonymous values related to visitor behavior, interests, or demographic information such as age or gender. Through reach analysis, we can, for example, identify when our online services or their functions and content are most frequently used or likely to encourage repeat visits. It also enables us to determine which areas need optimization.

In addition to web analytics, we may also use testing procedures to test and optimize different versions of our online services or their components.

Unless otherwise specified below, profiles (i.e., data combined from a usage process) may be created for these purposes, and information can be stored in and later retrieved from a browser or device. The data collected includes, in particular, visited websites and elements used on them, as well as technical information such as the browser used, the computer system, and information about usage times. If users have given consent to the collection of their location data to us or to the providers of the services we use, the processing of location data is also possible.

Additionally, users' IP addresses are stored. However, we use an IP masking process (i.e., pseudonymization by shortening the IP address) to protect users. In general, no clear user data (such as email addresses or names) is stored as part of web analytics, A/B testing, or optimization. Instead, pseudonyms are used. This means that neither we nor the providers of the software used know the actual identity of the users, only the information stored in their profiles for the respective procedures.

Legal basis information: If we ask users for their consent to use third-party providers, the legal basis for data processing is consent. Otherwise, user data is processed based on our legitimate interests (i.e., our interest in efficient, economic, and user-friendly services). In this context, we would also like to point out the information on the use of cookies in this privacy policy.

  • Processed data types: Usage data (e.g. page views and duration of visit, click paths, intensity and frequency of use, types of devices and operating systems used, interactions with content and features). Meta, communication and process data (e.g. IP addresses, timestamps, identification numbers, involved parties).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Purposes of processing and legitimate interests: Web Analytics (e.g. access statistics, recognition of returning visitors). Profiles with user-related information (Creating user profiles).
  • Retention and deletion: Deletion in accordance with the information provided in the section "General Information on Data Retention and Deletion". Storage of cookies for up to 2 years (Unless otherwise stated, cookies and similar storage methods may be stored on users' devices for a period of two years.).
  • Security measures: IP Masking (Pseudonymization of the IP address).
  • Legal Basis: Consent (Article 6 (1) (a) GDPR). Legitimate Interests (Article 6 (1) (f) GDPR).

Further information on processing methods, procedures and services used:

  • Matomo (without cookies): Matomo is a data protection friendly web analysis software, which is used without cookies and in which the recognition of returning users is carried out with the help of a so-called "digital fingerprint", which is stored anonymously and changed every 24 hours; in the case of the "digital fingerprint", user movements within our online services are recorded with the help of pseudonymised IP addresses in combination with user-side browser settings in such a way that conclusions about the identity of individual users are not possible. User data collected through the use of Matomo is processed only by us and is not shared with third parties; Legal Basis: Legitimate Interests (Article 6 (1) (f) GDPR); Website: https://matomo.org/. Security measures: IP Masking (Pseudonymization of the IP address).

Changes and Updates

We kindly ask you to inform yourself regularly about the contents of our data protection declaration. We will adjust the privacy policy as changes in our data processing practices make this necessary. We will inform you as soon as the changes require your cooperation (e.g. consent) or other individual notification.

If we provide addresses and contact information of companies and organizations in this privacy policy, we ask you to note that addresses may change over time and to verify the information before contacting us.

Terminology and Definitions

In this section, you will find an overview of the terminology used in this privacy policy. Where the terminology is legally defined, their legal definitions apply. The following explanations, however, are primarily intended to aid understanding.

  • Controller: "Controller" means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data.
  • Log data: Protocol data, or log data, refer to information regarding events or activities that have been logged within a system or network. These data typically include details such as timestamps, IP addresses, user actions, error messages, and other specifics about the usage or operation of a system. Protocol data is often used for analyzing system issues, monitoring security, or generating performance reports.
  • Meta, communication and process data: Meta-, communication, and procedural data are categories that contain information about how data is processed, transmitted, and managed. Meta-data, also known as data about data, include information that describes the context, origin, and structure of other data. They can include details about file size, creation date, the author of a document, and modification histories. Communication data capture the exchange of information between users across various channels, such as email traffic, call logs, messages in social networks, and chat histories, including the involved parties, timestamps, and transmission paths. Procedural data describe the processes and operations within systems or organisations, including workflow documentations, logs of transactions and activities, and audit logs used for tracking and verifying procedures.
  • Personal Data: "personal data" means any information relating to an identified or identifiable natural person ("data subject"); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
  • Processing: The term "processing" covers a wide range and practically every handling of data, be it collection, evaluation, storage, transmission or erasure.
  • Profiles with user-related information: The processing of "profiles with user-related information", or "profiles" for short, includes any kind of automated processing of personal data that consists of using these personal data to analyse, evaluate or predict certain personal aspects relating to a natural person (depending on the type of profiling, this may include different information concerning demographics, behaviour and interests, such as interaction with websites and their content, etc.) (e.g. interests in certain content or products, click behaviour on a website or location). Cookies and web beacons are often used for profiling purposes.
  • Usage data: Usage data refer to information that captures how users interact with digital products, services, or platforms. These data encompass a wide range of information that demonstrates how users utilise applications, which features they prefer, how long they spend on specific pages, and through what paths they navigate an application. Usage data can also include the frequency of use, timestamps of activities, IP addresses, device information, and location data. They are particularly valuable for analysing user behaviour, optimising user experiences, personalising content, and improving products or services. Furthermore, usage data play a crucial role in identifying trends, preferences, and potential problem areas within digital offerings
  • Web Analytics: Web Analytics serves the evaluation of visitor traffic of online services and can determine their behavior or interests in certain information, such as content of websites. With the help of web analytics, website owners, for example, can recognize at what time visitors visit their website and what content they are interested in. This enables them, for example, to better adapt the content of their websites to the needs of their visitors.
