Overview of processing operations

The following table summarises the types of data processed, the purposes for which they are processed and the concerned data subjects.

Categories of Data Subjects

Purposes of Processing

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.

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 Law on Protection against Misuse of Personal Data in Data Processing (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: If you are located in Switzerland, we process your data based on the Federal Act on Data Protection (referred to as "Swiss DPA"). Unlike the GDPR, for instance, the Swiss DPA does not generally require that a legal basis for processing personal data be stated and that the processing of personal data is conducted in good faith, lawfully and proportionately (Art. 6 para. 1 and 2 of the Swiss DPA). Furthermore, we only collect personal data for a specific purpose recognizable to the data subject and process it only in a manner compatible with this purpose (Art. 6 para. 3 of the Swiss DPA).

Reference to the applicability of the GDPR and the Swiss DPA: These privacy policy serves both to provide information pursuant to the Swiss Federal Act on Data Protection (FADP) and the General Data Protection Regulation (GDPR). For this reason, we ask you to note that due to the broader spatial application and comprehensibility, the terms used in the GDPR are applied. In particular, instead of the terms used in the Swiss FADP such as "processing" of "personal data", "predominant interest", and "particularly sensitive personal data", the terms used in the GDPR, namely "processing" of "personal data", as well as "legitimate interest" and "special categories of data" are used. However, the legal meaning of these terms will continue to be determined according to the Swiss FADP within its scope of application.

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.

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.

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

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:

Business services

We process data of our contractual and business partners, e.g. customers and interested parties (collectively referred to as "contractual partners") within the context of contractual and comparable legal relationships as well as associated actions and communication with the contractual partners or pre-contractually, e.g. to answer inquiries.

We process this data in order to fulfill our contractual obligations. These include, in particular, the obligations to provide the agreed services, any update obligations and remedies in the event of warranty and other service disruptions. In addition, we process the data to protect our rights and for the purpose of administrative tasks associated with these obligations and company organization. Furthermore, we process the data on the basis of our legitimate interests in proper and economical business management as well as security measures to protect our contractual partners and our business operations from misuse, endangerment of their data, secrets, information and rights (e.g. for the involvement of telecommunications, transport and other auxiliary services as well as subcontractors, banks, tax and legal advisors, payment service providers or tax authorities). Within the framework of applicable law, we only disclose the data of contractual partners to third parties to the extent that this is necessary for the aforementioned purposes or to fulfill legal obligations. Contractual partners will be informed about further forms of processing, e.g. for marketing purposes, within the scope of this privacy policy.

Which data are necessary for the aforementioned purposes, we inform the contracting partners before or in the context of the data collection, e.g. in online forms by special marking (e.g. colors), and/or symbols (e.g. asterisks or the like), or personally.

We delete the data after expiry of statutory warranty and comparable obligations, i.e. in principle after expiry of 4 years, unless the data is stored in a customer account or must be kept for legal reasons of archiving. The statutory retention period for documents relevant under tax law as well as for commercial books, inventories, opening balance sheets, annual financial statements, the instructions required to understand these documents and other organizational documents and accounting records is ten years and for received commercial and business letters and reproductions of sent commercial and business letters six years. The period begins at the end of the calendar year in which the last entry was made in the book, the inventory, the opening balance sheet, the annual financial statements or the management report was prepared, the commercial or business letter was received or sent, or the accounting document was created, furthermore the record was made or the other documents were created.

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. This data processing supports and facilitates business processes in areas such as customer management, sales, payment transactions, accounting, and project management.

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. This also includes data that must be stored for longer periods due to tax law and legal obligations to provide evidence.

Use of online platforms for listing and sales purposes

We offer our services on online platforms operated by other service providers. In addition to our privacy policy, the privacy policies of the respective platforms apply. This is particularly true with regard to the payment process and the methods used on the platforms for performance measuring and behaviour-related marketing.

Further information on processing methods, procedures and services used:

Payment Procedure

Within the framework of contractual and other legal relationships, due to legal obligations or otherwise on the basis of our legitimate interests, we offer data subjects efficient and secure payment options and use other service providers for this purpose in addition to banks and credit institutions (collectively referred to as "payment service providers").

The data processed by the payment service providers includes inventory data, such as the name and address, bank data, such as account numbers or credit card numbers, passwords, TANs and checksums, as well as the contract, total and recipient-related information. The information is required to carry out the transactions. However, the data entered is only processed by the payment service providers and stored with them. I.e. we do not receive any account or credit card related information, but only information with confirmation or negative information of the payment. Under certain circumstances, the data may be transmitted by the payment service providers to credit agencies. The purpose of this transmission is to check identity and creditworthiness. Please refer to the terms and conditions and data protection information of the payment service providers.

The terms and conditions and data protection information of the respective payment service providers apply to the payment transactions and can be accessed within the respective websites or transaction applications. We also refer to these for further information and the assertion of revocation, information and other data subject rights.

Blogs and publication media

We use blogs or comparable means of online communication and publication (hereinafter "publication medium"). Readers' data will only be processed for the purposes of the publication medium to the extent necessary for its presentation and communication between authors and readers or for security reasons. For the rest, we refer to the information on the processing of visitors to our publication medium within the scope of this privacy policy.

Contact and Inquiry Management

When contacting us (e.g. via mail, contact form, e-mail, telephone or via social media) as well as in the context of existing user and business relationships, the information of the inquiring persons is processed to the extent necessary to respond to the contact requests and any requested measures.

Further information on processing methods, procedures and services used:

Cloud Services

We use Internet-accessible software services (so-called "cloud services", also referred to as "Software as a Service") provided on the servers of its providers for the storage and management of content (e.g. document storage and management, exchange of documents, content and information with certain recipients or publication of content and information).

Within this framework, personal data may be processed and stored on the provider's servers insofar as this data is part of communication processes with us or is otherwise processed by us in accordance with this privacy policy. This data may include in particular master data and contact data of data subjects, data on processes, contracts, other proceedings and their contents. Cloud service providers also process usage data and metadata that they use for security and service optimization purposes.

If we use cloud services to provide documents and content to other users or publicly accessible websites, forms, etc., providers may store cookies on users' devices for web analysis or to remember user settings (e.g. in the case of media control).

Further information on processing methods, procedures and services used:

Newsletter and Electronic Communications

We send newsletters, emails, and other electronic notifications (hereinafter "newsletters") exclusively with the consent of the recipients or based on a legal basis. 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.

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.

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.
