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.
• Performance of a contract and prior requests (Article 6 (1) (b) GDPR) - 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 (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.

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.

Data Transfer within the Organization: We may transfer personal data to other departments or units within our organisation or grant them access to it. If the data is shared for administrative purposes, it is based on our legitimate business and economic interests or occurs if it is necessary to fulfil our contractual obligations or if the data subjects have given their consent or a legal permission exists.

International data transfers

Data Processing in Third Countries: If we transfer data to a third country (i.e., outside the European Union (EU) or the European Economic Area (EEA)), or if this occurs in the context of using third-party services or the disclosure or transfer of data to other individuals, entities, or companies (which becomes apparent either from the postal address of the respective provider or when explicitly mentioned in the privacy policy regarding data transfer to third countries), this is always done in accordance with legal requirements.

For data transfers to the USA, we primarily rely on the Data Privacy Framework (DPF), which has been recognized as a secure legal framework by the EU Commission's adequacy decision of July 10, 2023. Additionally, we have concluded Standard Contractual Clauses with the respective providers, which comply with the EU Commission's requirements and establish contractual obligations to protect your data.

This dual safeguard ensures comprehensive protection of your data: The DPF serves as the primary level of protection, while the Standard Contractual Clauses act as an additional security measure. Should any changes occur within the DPF framework, the Standard Contractual Clauses will serve as a reliable fallback option. This ensures that your data remains adequately protected even in the event of political or legal changes.

For individual service providers, we will inform you whether they are certified under the DPF and if Standard Contractual Clauses are in place. The list of certified companies and further information about the DPF can be found on the U.S. Department of Commerce's website at https://www.dataprivacyframework.gov/.

For data transfers to other third countries, appropriate safeguards apply, particularly Standard Contractual Clauses, explicit consent, or legally required transfers. Information on third-country transfers and applicable adequacy decisions can be found in the information provided by the EU Commission: https://commission.europa.eu/law/law-topic/data-protection/international-dimension-data-protection_en.

We will inform you which of our service providers are certified under the Data Privacy Framework as part of our data protection notices.

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.

Start of the period at the end of the year: If a period does not expressly start on a specific date and lasts at least one year, it automatically begins at the end of the calendar year in which the event triggering the period occurred. In the case of ongoing contractual relationships in the context of which data is stored, the event triggering the deadline is the time at which the termination or other termination of the legal relationship takes effect.

Rights of Data Subjects

Rights of the Data Subjects under the GDPR: As data subject, you are entitled to various rights under the GDPR, which arise in particular from Articles 15 to 21 of the GDPR:

• Right to Object: You have the right, on grounds arising from your particular situation, to object at any time to the processing of your personal data which is based on letter (e) or (f) of Article 6(1) GDPR, including profiling based on those provisions. Where personal data are processed for direct marketing purposes, you have the right to object at any time to the processing of the personal data concerning you for the purpose of such marketing, which includes profiling to the extent that it is related to such direct marketing.
• Right of withdrawal for consents: You have the right to revoke consents at any time.
• Right of access: You have the right to request confirmation as to whether the data in question will be processed and to be informed of this data and to receive further information and a copy of the data in accordance with the provisions of the law.
• Right to rectification: You have the right, in accordance with the law, to request the completion of the data concerning you or the rectification of the incorrect data concerning you.
• Right to Erasure and Right to Restriction of Processing: In accordance with the statutory provisions, you have the right to demand that the relevant data be erased immediately or, alternatively, to demand that the processing of the data be restricted in accordance with the statutory provisions.
• Right to data portability: You have the right to receive data concerning you which you have provided to us in a structured, common and machine-readable format in accordance with the legal requirements, or to request its transmission to another controller.
• Complaint to the supervisory authority: In accordance with the law and without prejudice to any other administrative or judicial remedy, you also have the right to lodge a complaint with a data protection supervisory authority, in particular a supervisory authority in the Member State where you habitually reside, the supervisory authority of your place of work or the place of the alleged infringement, if you consider that the processing of personal data concerning you infringes the GDPR.

Business processes and operations

Personal data of service recipients and clients - including customers, clients, or in specific cases, mandates, patients, or business partners as well as other third parties - are processed within the framework of contractual and comparable legal relationships and pre-contractual measures such as the initiation of business relations.

The collected data is used to fulfil contractual obligations and make business processes efficient. This includes the execution of business transactions, the management of customer relationships, the optimisation of sales strategies, and ensuring internal invoicing and financial processes. Additionally, the data supports the protection of the rights of the controller and promotes administrative tasks as well as the organisation of the company.

Personal data may be transferred to third parties if necessary for fulfilling the mentioned purposes or legal obligations. After legal retention periods expire or when the purpose of processing no longer applies, the data will be deleted.

Storage duration: The following types of cookies are distinguished based on their storage duration:

• Temporary cookies (also: session cookies): Temporary cookies are deleted at the latest after a user leaves an online service and closes their device (e.g., browser or mobile application).
• Permanent cookies: Permanent cookies remain stored even after the device is closed. For example, the login status can be saved, and preferred content can be displayed directly when the user revisits a website. Additionally, the user data collected with cookies may be used for audience measurement.

If the contents of the newsletter are specified during registration for the newsletter, these contents are decisive for the users' consent. Normally, providing your email address is sufficient to sign up for our newsletter. However, to offer you a personalised service, we may ask for your name for personal salutation in the newsletter or for additional information if necessary for the purpose of the newsletter.

Deletion and restriction of processing: We may store unsubscribed email addresses for up to three years based on our legitimate interests before deleting them to be able to demonstrate previously given consent. The processing of these data is limited to the purpose of potentially defending against claims. An individual request for deletion is possible at any time, provided that at the same time the former existence of consent is confirmed. In case of obligations to permanently observe objections, we reserve the right to store the email address solely for this purpose in a blocklist.

The logging of the registration process is based on our legitimate interests for the purpose of proving its proper execution. If we commission a service provider to send emails, this is done based on our legitimate interests in an efficient and secure mailing system.

Further information on processing methods, procedures and services used:

• Measurement of opening rates and click rates: The newsletters contain what is known as a "web beacon", i.e. a one-pixel file that is retrieved from our server, or the server of our Service Provider if we use a mailing service, when the newsletter is opened. During this retrieval, technical information such as details about the browser and your system, as well as your IP address and the time of retrieval are collected. This information is used to improve our newsletters technically based on the technical data or to analyse target groups and their reading behaviour according to their access locations (which can be determined using the IP address) or access times. This analysis also includes determining whether and when newsletters are opened and which links are clicked. The collected information is assigned to individual newsletter recipients and stored in their profiles until deletion. On this basis, user profiles are created in which usage behaviour and user characteristics are stored. The measurement of open and click rates, as well as the storage of measurement results in users' profiles and further processing thereof, takes place on the basis of users' consent. It is unfortunately not possible to separately withdraw consent for performance measurement; in this case, the entire newsletter subscription must be cancelled or objected to. In such cases, the stored profile information will be deleted; Legal Basis: Consent (Article 6 (1) (a) GDPR).

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). Targeting (e.g. profiling based on interests and behaviour, use of cookies).
• 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).

Profiles in Social Networks (Social Media)

We maintain online presences within social networks and process user data in this context in order to communicate with the users active there or to offer information about us.

We would like to point out that user data may be processed outside the European Union. This may entail risks for users, e.g. by making it more difficult to enforce users' rights.

In addition, user data is usually processed within social networks for market research and advertising purposes. For example, user profiles can be created on the basis of user behaviour and the associated interests of users. The user profiles can then be used, for example, to place advertisements within and outside the networks which are presumed to correspond to the interests of the users. For these purposes, cookies are usually stored on the user's computer, in which the user's usage behaviour and interests are stored. Furthermore, data can be stored in the user profiles independently of the devices used by the users (especially if the users are members of the respective networks or will become members later on).

For a detailed description of the respective processing operations and the opt-out options, please refer to the respective data protection declarations and information provided by the providers of the respective networks.

Also in the case of requests for information and the exercise of rights of data subjects, we point out that these can be most effectively pursued with the providers. Only the providers have access to the data of the users and can directly take appropriate measures and provide information. If you still need help, please do not hesitate to contact us.

Plugins and embedded functions and content

Within our online services, we integrate functional and content elements that are obtained from the servers of their respective providers (hereinafter referred to as "third-party providers"). These may, for example, be graphics, videos or city maps (hereinafter uniformly referred to as "Content").

The integration always presupposes that the third-party providers of this content process the IP address of the user, since they could not send the content to their browser without the IP address. The IP address is therefore required for the presentation of these contents or functions. We strive to use only those contents, whose respective offerers use the IP address only for the distribution of the contents. Third parties may also use so-called pixel tags (invisible graphics, also known as "web beacons") for statistical or marketing purposes. The "pixel tags" can be used to evaluate information such as visitor traffic on the pages of this website. The pseudonymous information may also be stored in cookies on the user's device and may include technical information about the browser and operating system, referring websites, visit times and other information about the use of our website, as well as may be linked to such information from other sources.

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.

• Contact data: Contact details are essential information that enables communication with individuals or organizations. They include, among others, phone numbers, postal addresses, and email addresses, as well as means of communication like social media handles and instant messaging identifiers.
• Content Delivery Network (CDN): A "Content Delivery Network" (CDN) is a service with whose help contents of our online services, in particular large media files, such as graphics or scripts, can be delivered faster and more securely with the help of regionally distributed servers connected via the Internet.
• Content data: Content data comprise information generated in the process of creating, editing, and publishing content of all types. This category of data may include texts, images, videos, audio files, and other multimedia content published across various platforms and media. Content data are not limited to the content itself but also include metadata providing information about the content, such as tags, descriptions, authorship details, and publication dates.
• Contract data: Contract data are specific details pertaining to the formalisation of an agreement between two or more parties. They document the terms under which services or products are provided, exchanged, or sold. This category of data is essential for managing and fulfilling contractual obligations and includes both the identification of the contracting parties and the specific terms and conditions of the agreement. Contract data may encompass the start and end dates of the contract, the nature of the agreed-upon services or products, pricing arrangements, payment terms, termination rights, extension options, and special conditions or clauses. They serve as the legal foundation for the relationship between the parties and are crucial for clarifying rights and duties, enforcing claims, and resolving disputes.
• 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.
• Employees: As employees, individuals are those who are engaged in an employment relationship, whether as staff, employees, or in similar positions. Employment refers to a legal relationship between an employer and an employee, established through an employment contract or agreement. It entails the obligation of the employer to pay the employee remuneration while the employee performs their work. The employment relationship encompasses various stages, including establishment, where the employment contract is concluded, execution, where the employee carries out their work activities, and termination, when the employment relationship ends, whether through termination, mutual agreement, or otherwise. Employee data encompasses all information pertaining to these individuals within the context of their employment. This includes aspects such as personal identification details, identification numbers, salary and banking information, working hours, holiday entitlements, health data, and performance assessments.
• Inventory data: Inventory data encompass essential information required for the identification and management of contractual partners, user accounts, profiles, and similar assignments. These data may include, among others, personal and demographic details such as names, contact information (addresses, phone numbers, email addresses), birth dates, and specific identifiers (user IDs). Inventory data form the foundation for any formal interaction between individuals and services, facilities, or systems, by enabling unique assignment and communication.
• 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.
• Payment Data: Payment data comprise all information necessary for processing payment transactions between buyers and sellers. This data is crucial for e-commerce, online banking, and any other form of financial transaction. It includes details such as credit card numbers, bank account information, payment amounts, transaction dates, verification numbers, and billing information. Payment data may also contain information on payment status, chargebacks, authorizations, and fees.
• 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.
• Targeting: "Tracking" is the term used when the behaviour of users can be traced across several websites. As a rule, behavior and interest information with regard to the websites used is stored in cookies or on the servers of the tracking technology providers (so-called profiling). This information can then be used, for example, to display advertisements to users presumably corresponding to their interests.
• 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. For the purposes of web analytics , pseudonymous cookies and web beacons are often used to recognize returning visitors and thus obtain more precise analyses of the use of an online service.
