Applicable Legal Bases
Applicable legal bases under the GDPR: Below you will find 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. Should more specific legal bases be relevant in individual cases, we will inform you of these in this 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 enquiries (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.
- Legal obligation (Art. 6(1)(c) GDPR) – Processing is necessary for compliance with a legal obligation to which the controller is subject.
- 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 provisions of the GDPR, national data protection regulations apply in Germany (German law). These include, in particular, the German Federal Data Protection Act (Bundesdatenschutzgesetz – BDSG). The BDSG contains specific provisions on the right of access, the right to erasure, the right to object, the processing of special categories of personal data, processing for other purposes, and the transfer and automated individual decision-making, including profiling. Furthermore, the data protection laws of the individual German federal states (Landesdatenschutzgesetze) may also apply.
Security Measures
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, circumstances, and purposes of processing, as well as the different likelihood and severity of the risk to the rights and freedoms of natural persons, in order to ensure a level of protection appropriate to the risk.
These 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, input, disclosure, ensuring availability, and separation of data. Furthermore, we have established procedures that ensure the exercise of data subjects' rights, the deletion of data, and responses to data threats. We also take the protection of personal data into account from the outset in the development and selection of hardware, software, and processes, in accordance with the principle of data protection by design and by default.
Securing online connections through TLS/SSL encryption technology (HTTPS): To protect the data of users transmitted via our online services from unauthorised access, we rely on 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 transmitted between the website or application and the user's browser (or between two servers), thereby protecting the data from unauthorised access. TLS, as the more advanced and secure version of SSL, ensures that all data transmissions meet the highest security standards. When a website is secured by 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 transmitted securely and in encrypted form.
Transfer of Personal Data
In the course of our processing of personal data, it may occur that the data is transferred to, or disclosed to, other entities, companies, legally independent organisational units, or persons. The recipients of this data may include, for example, service providers entrusted with IT tasks, or providers of services and content integrated into a website. In such cases, we comply with the legal requirements and, in particular, conclude appropriate contracts or agreements with the recipients of your data that serve to protect your data.
International Data Transfers
Data processing in third countries: Where we transfer data to a third country (i.e. outside the European Union (EU) or the European Economic Area (EEA)), or where this occurs in the context of the use of third-party services or the disclosure or transfer of data to other persons, entities, or companies (which is apparent from the postal address of the respective provider or when this privacy policy explicitly refers to data transfers to third countries), this is always done in compliance with legal requirements.
For data transfers to the USA, we primarily rely on the Data Privacy Framework (DPF), which was recognised as a safe legal framework by an adequacy decision of the EU Commission dated 10 July 2023. In addition, we have concluded Standard Contractual Clauses with the respective providers that comply with the requirements of the EU Commission and establish contractual obligations to protect your data.
This dual safeguard ensures comprehensive protection of your data: The DPF forms the primary layer of protection, while the Standard Contractual Clauses serve as an additional safeguard. Should changes arise within the framework of the DPF, the Standard Contractual Clauses serve as a reliable fallback option. This way, we ensure that your data remains adequately protected at all times, even in the event of political or legal changes.
For the individual service providers, we inform you whether they are certified under the DPF and whether Standard Contractual Clauses are in place. Further information on the DPF and a list of certified companies can be found on the website of the US Department of Commerce at https://www.dataprivacyframework.gov/.
For data transfers to other third countries, corresponding safeguards apply, in particular 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.
General Information on Data Retention and Deletion
We delete personal data that we process in accordance with legal requirements as soon as the underlying consent is revoked or no further legal basis for processing exists. This applies to cases where the original purpose of processing no longer applies or the data is no longer needed. Exceptions to this rule exist where statutory obligations or special interests require 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 enforcement or for the 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 that specifically applies to certain processing activities.
Where multiple retention periods or deletion deadlines apply to a particular piece of data, the longest period shall always prevail. Data that is no longer retained for its originally intended purpose but due to legal requirements or other reasons shall only be processed for the reasons that justify its retention.
Data retention and deletion: The following general periods apply for retention and archiving under German law (applicable as the controller is based in Germany):
- 10 years – Retention period for books and records, annual financial statements, inventories, management reports, opening balance sheets, and the working instructions and other organisational documents necessary for their understanding (§ 147(1) No. 1 in conjunction with (3) AO, § 14b(1) UStG, § 257(1) No. 1 in conjunction with (4) HGB).
- 8 years – Accounting vouchers, such as invoices and cost receipts (§ 147(1) No. 4 and 4a in conjunction with (3) sentence 1 AO and § 257(1) No. 4 in conjunction with (4) HGB).
- 6 years – Other business documents: received commercial or business correspondence, copies of sent commercial or business correspondence, other documents insofar as they are relevant for taxation purposes, e.g. timesheets, cost accounting records, calculation documents, price labels, as well as payroll documents insofar as they are not already accounting vouchers, and till receipts (§ 147(1) No. 2, 3, 5 in conjunction with (3) AO, § 257(1) No. 2 and 3 in conjunction with (4) HGB).
- 3 years – Data required to consider potential warranty and compensation claims or similar contractual claims and rights, and to process related enquiries, based on past business experience and standard industry practices, shall be retained for the duration of the regular statutory limitation period of three years (§§ 195, 199 BGB).
Start of period at year-end: Where a period does not expressly commence on a specific date and is at least one year, it shall automatically begin at the end of the calendar year in which the event triggering the period occurred. In the case of ongoing contractual relationships in which data is stored, the event triggering the period is the date on which the termination or other ending of the legal relationship takes effect.
Rights of Data Subjects
Rights of data subjects under the GDPR: As a data subject, you are entitled to various rights under the GDPR, in particular those arising from Articles 15 to 21 GDPR:
- Right to object: You have the right to object, on grounds relating to your particular situation, at any time to the processing of personal data concerning you which is based on Art. 6(1)(e) or (f) GDPR; this also applies to profiling based on these provisions. Where personal data concerning you is processed for direct marketing purposes, you have the right to object at any time to the processing of personal data concerning you for such marketing; this also applies to profiling insofar as it is related to such direct marketing.
- Right to withdraw consent: You have the right to withdraw consent at any time.
- Right of access: You have the right to obtain confirmation as to whether data concerning you is being processed and to obtain information about such data, as well as further information and a copy of the data in accordance with the legal requirements.
- Right to rectification: You have the right, in accordance with the legal requirements, to request the completion of data concerning you or the rectification of inaccurate data concerning you.
- Right to erasure and restriction of processing: You have the right, in accordance with the legal requirements, to request that data concerning you be erased without undue delay, or alternatively to request restriction of processing of the data in accordance with the legal requirements.
- Right to data portability: You have the right to receive data concerning you, which you have provided to us, in a structured, commonly used and machine-readable format in accordance with the legal requirements, or to request its transmission to another controller.
- Complaint to a supervisory authority: Without prejudice to any other administrative or judicial remedy, you have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work, or place of the alleged infringement, if you consider that the processing of personal data concerning you infringes the GDPR. The competent supervisory authority for the controller is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW).
Provision of the Online Offering and Web Hosting
We process the data of users in order to provide them with our online services. For this purpose, we process the user's IP address, which is necessary to deliver the content and functions of our online services to the user's browser or device.
- Types of data processed: Usage data (e.g. page views and time spent on pages, click paths, usage intensity and frequency, device types and operating systems used, interactions with content and features); meta, communication and procedural data (e.g. IP addresses, timestamps, identification numbers, persons involved). Log data (e.g. log files concerning logins or data retrieval, or access times).
- Data subjects: Users (e.g. website visitors, users of online services).
- Purposes of processing and legitimate interests: Provision of our Online Offering and user experience; information technology infrastructure (operation and provision of information systems and technical devices (computers, servers, etc.)). Security measures.
- Retention and deletion: Deletion in accordance with the information provided in the section "General Information on Data Retention and Deletion".
- Legal bases: Legitimate interests (Art. 6(1)(f) GDPR).
Further notes on processing activities, procedures and services:
- Provision of Online Offering on rented server space: For the provision of our Online Offering, we use server space, computing capacity, and software that we rent or otherwise obtain from a corresponding server provider (also known as a "web host"); Legal bases: Legitimate interests (Art. 6(1)(f) GDPR).
- Collection of access data and log files: Access to our Online Offering is logged in the form of so-called "server log files". Server log files may include the address and name of the web pages and files accessed, date and time of access, data volume transferred, notification of successful access, browser type and version, the user's operating system, referrer URL (the previously visited page), and, as a rule, IP addresses and the requesting provider. The server log files may be used, on the one hand, for security purposes, e.g. to prevent server overload (particularly in the case of abusive attacks, so-called DDoS attacks), and, on the other hand, to ensure server utilisation and stability; Legal bases: Legitimate interests (Art. 6(1)(f) GDPR). Deletion of data: Log file information is stored for a maximum of 30 days and then deleted or anonymised. Data whose further retention is required for evidentiary purposes is exempt from deletion until the respective incident has been finally resolved.
Use of Cookies
The term "cookies" refers to functions that store information on users' devices and read information from them. Cookies may also be used for various purposes, such as ensuring the functionality, security, and convenience of online offerings, as well as for analysing visitor traffic. We use cookies in accordance with legal requirements. To this end, we obtain the prior consent of users where required. Where consent is not necessary, we rely on our legitimate interests. This applies when the storage and reading of information is essential in order to provide expressly requested content and functions. This includes, for example, the storage of settings and ensuring the functionality and security of our Online Offering. Consent may be revoked at any time. We clearly inform about the scope and which cookies are used.
Notes on data protection legal bases: Whether we process personal data using cookies depends on consent. Where consent has been given, it serves as the legal basis. Without consent, we rely on our legitimate interests, which are explained above in this section and in the context of the respective services and procedures.
Retention period: With regard to the retention period, the following types of cookies are distinguished:
- Temporary cookies (also: session cookies): Temporary cookies are deleted at the latest after a user has left an online offering and closed their device (e.g. browser or mobile application).
- Persistent cookies: Persistent cookies remain stored even after the device has been closed. For example, the login status can be stored and preferred content displayed directly when the user revisits a website. Likewise, user data collected with the help of cookies can be used for audience measurement. Unless we provide users with explicit information about the type and retention period of cookies (e.g. when obtaining consent), they should assume that cookies are persistent and that the retention period can be up to two years.
General information on revocation and objection (opt-out): Users may revoke the consent they have given at any time and also file an objection to processing in accordance with the legal requirements, including via the privacy settings of their browser.
- Types of data processed: Meta, communication and procedural data (e.g. IP addresses, timestamps, identification numbers, persons involved).
- Data subjects: Users (e.g. website visitors, users of online services).
- Legal bases: Legitimate interests (Art. 6(1)(f) GDPR). Consent (Art. 6(1)(a) GDPR).
Further notes on processing activities, procedures and services:
- Processing of cookie data based on consent: We use a consent management solution through which the consent of users to the use of cookies or to the procedures and providers mentioned in the consent management solution is obtained. This procedure serves to obtain, log, manage, and revoke consent, in particular with regard to the use of cookies and comparable technologies used to store, read, and process information on users' devices. Within this procedure, users' consent to the use of cookies and the associated processing of information, including the specific processing activities and providers named in the consent management procedure, is obtained. Users also have the option of managing and revoking their consent. Consent declarations are stored in order to avoid repeated queries and to be able to provide proof of consent in accordance with legal requirements. Storage takes place on the server side and/or in a cookie (so-called opt-in cookie) or by means of comparable technologies, in order to be able to assign consent to a specific user or their device. Unless specific information on the providers of consent management services is available, the following general information applies: The duration of storage of consent is up to two years. A pseudonymous user identifier is created and stored together with the time of consent, information about the scope of consent (e.g. relevant categories of cookies and/or service providers) and information about the browser, system, and device used; Legal bases: Consent (Art. 6(1)(a) GDPR).
- Cookies by Cal.com: This website integrates an appointment booking widget by Cal.com Inc. The widget is only loaded after active user interaction (clicking on the appointment booking). When loading the Cal.com embed, Cal.com may set its own cookies that are required for the functionality of the appointment booking. In this process, your IP address is transmitted to Cal.com. Legal bases: Consent (Art. 6(1)(a) GDPR) through active interaction. For further information, please refer to Cal.com's privacy policy.
Contact and Enquiry Management
When contacting us (e.g. by post, contact form, email, telephone, or via social media) as well as in the context of existing user and business relationships, the information provided by the enquiring persons is processed insofar as this is necessary to respond to the contact enquiries and any requested measures.
- Types of data processed: Contact data (e.g. postal and email addresses or telephone numbers); content data (e.g. textual or visual messages and contributions, as well as information relating to them, such as authorship details or time of creation). Meta, communication and procedural data (e.g. IP addresses, timestamps, identification numbers, persons involved).
- Data subjects: Communication partners.
- Purposes of processing and legitimate interests: Communication; organisational and administrative processes; feedback (e.g. collecting feedback via online forms). Provision of our Online Offering and user experience.
- Retention and deletion: Deletion in accordance with the information provided in the section "General Information on Data Retention and Deletion".
- Legal bases: Legitimate interests (Art. 6(1)(f) GDPR). Performance of a contract and pre-contractual enquiries (Art. 6(1)(b) GDPR).
Further notes on processing activities, procedures and services:
- Contact form: When contacting us via our contact form, email, or other means of communication, we process the personal data transmitted to us in order to respond to and handle the respective enquiry. This typically includes information such as name, contact details, and, where applicable, further information communicated to us that is necessary for appropriate processing. We use this data exclusively for the stated purpose of contact and communication; Legal bases: Performance of a contract and pre-contractual enquiries (Art. 6(1)(b) GDPR), legitimate interests (Art. 6(1)(f) GDPR).
- Storage of contact data in Supabase: The data submitted via the contact form (name, company, role, reason for contact, message) is stored in a database hosted by Supabase Inc. The database server is located in Ireland (EU, eu-west-1). Processing is based on Art. 6(1)(b) GDPR (pre-contractual measures) and Art. 6(1)(f) GDPR (legitimate interest in processing enquiries). Data will be deleted once it is no longer necessary for the purpose for which it was collected, at the latest after 12 months.
Web Analytics, Monitoring and Optimisation
Web analytics (also referred to as "audience measurement") is used to evaluate the visitor traffic of our Online Offering and may include behavioural data, interests, or demographic information about visitors, such as age or gender, as pseudonymous values. With the help of audience analysis, we can, for example, recognise at what time our Online Offering or its functions or content are most frequently used, or invite re-use. Likewise, we are able to identify which areas require optimisation.
In addition to web analytics, we may also use testing procedures to test and optimise, for example, different versions of our Online Offering or its components.
Unless otherwise stated below, profiles — i.e. data consolidated relating to a usage process — may be created for these purposes, and information may be stored in a browser or device and then read. The information collected includes, in particular, websites visited and elements used on those websites, as well as technical information such as the browser used, the computer system used, and information on usage times. Where users have consented to the collection of their location data, either to us or to the providers of the services we use, location data may also be processed.
Furthermore, the IP addresses of users are stored. However, we use an IP masking procedure (i.e. pseudonymisation by truncating the IP address) to protect users. In general, no clear-text data of users (such as email addresses or names) is stored in the context of web analytics, A/B testing, and optimisation, but rather pseudonyms. This means that neither we nor the providers of the software used know the actual identity of the users, but only the data stored in their profiles for the purposes of the respective procedures.
Notes on legal bases: Where we ask users for their consent to the use of third-party providers, the legal basis for data processing is consent. Otherwise, user data is processed on the basis of our legitimate interests (i.e. interest in efficient, cost-effective and user-friendly services). In this context, we would also like to draw your attention to the information on the use of cookies in this privacy policy.
- Types of data processed: Usage data (e.g. page views and time spent on pages, click paths, usage intensity and frequency, device types and operating systems used, interactions with content and features). Meta, communication and procedural data (e.g. IP addresses, timestamps, identification numbers, persons involved).
- Data subjects: Users (e.g. website visitors, users of online services).
- Purposes of processing and legitimate interests: Audience measurement (e.g. access statistics, recognition of returning visitors). Provision of our Online Offering and user experience.
- Retention and deletion: Deletion in accordance with the information provided in the section "General Information on Data Retention and Deletion".
- Security measures: IP masking (pseudonymisation of the IP address).
- Legal bases: Legitimate interests (Art. 6(1)(f) GDPR).

- Vercel Web Analytics: This website uses Vercel Web Analytics, a privacy-friendly, cookie-free analytics service provided by Vercel Inc. (440 N Barranca Ave #4133, Covina, CA 91723, USA). No cookies are set and no personal data is stored. The analysis is performed in a fully anonymised manner and only provides aggregated metrics (e.g. page views, country of origin, device type). It is not possible to identify individual users. Legal bases: Legitimate interests (Art. 6(1)(f) GDPR). Website: https://vercel.com/docs/analytics.
Changes and Updates
We kindly ask you to regularly inform yourself about the content of our privacy policy. We adapt the privacy policy as soon as changes to the data processing carried out by us make this necessary. We will inform you as soon as the changes require an act of participation on your part (e.g. consent) or other individual notification.
Where we provide addresses and contact information of companies and organisations in this privacy policy, please note that addresses may change over time and please verify the information before contacting them.
Definitions
This section provides you with an overview of the terms used in this privacy policy. Where terms are legally defined, their legal definitions apply. The following explanations are primarily intended to aid understanding.
- Content data: Content data encompasses information generated in the course of creating, editing, and publishing content of all kinds. This category of data may include texts, images, videos, audio files, and other multimedia content published on various platforms and media. Content data is not limited to the actual content but also includes metadata that provides information about the content itself, such as tags, descriptions, author information, and publication dates.
- Contact data: Contact data is essential information that enables communication with persons or organisations. It includes, among other things, telephone numbers, postal addresses, and email addresses, as well as communication means such as social media handles and instant messaging identifiers.
- Meta, communication and procedural data: Meta, communication and procedural data are categories that contain information about the manner in which data is processed, transmitted, and managed. Metadata, also known as data about data, includes information that describes the context, origin, and structure of other data. It may include information about file size, creation date, author of a document, and change histories. Communication data captures the exchange of information between users via various channels, such as email traffic, call logs, messages in social networks, and chat histories, including the persons involved, timestamps, and transmission paths. Procedural data describes the processes and workflows within systems or organisations, including workflow documentation, transaction and activity logs, and audit logs used for tracking and reviewing operations.
- Usage data: Usage data refers to information that captures how users interact with digital products, services, or platforms. This data encompasses a wide range of information that shows how users use applications, which features they prefer, how long they spend on certain pages, and the paths they navigate through an application. Usage data may also include frequency of use, timestamps of activities, IP addresses, device information, and location data. It is particularly valuable for analysing user behaviour, optimising user experiences, personalising content, and improving products or services. Furthermore, usage data plays a crucial role in identifying trends, preferences, and potential problem areas within digital offerings.
- Personal data: "Personal data" means any information relating to an identified or identifiable natural person (hereinafter "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 (e.g. cookie), or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural, or social identity of that natural person.
- Profiles with user-related information: The processing of "profiles with user-related information", or "profiles" for short, encompasses any form of automated processing of personal data that consists of using such personal data to analyse, evaluate, or predict certain personal aspects relating to a natural person (depending on the type of profiling, this may include various information concerning demographics, behaviour, and interests, such as interaction with websites and their content, etc.). Cookies and web beacons are frequently used for profiling purposes.
- Log data: Log data is information about events or activities that have been logged in a system or network. This data typically contains information such as timestamps, IP addresses, user actions, error messages, and other details about the use or operation of a system. Log data is often used for analysing system problems, security monitoring, or producing performance reports.
- Audience measurement: Audience measurement (also referred to as web analytics) is used to evaluate the visitor traffic of an online offering and may include the behaviour or interests of visitors in certain information, such as website content. With the help of audience analysis, operators of online offerings can, for example, recognise at what time users visit their websites and what content they are interested in. This enables them, for example, to better adapt the content of the websites to the needs of their visitors. Pseudonymous cookies and web beacons are frequently used for audience analysis purposes in order to recognise returning visitors and thus obtain more precise analyses of the use of an online offering.
- Controller: The "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.
- Processing: "Processing" means any operation or set of operations which is performed on personal data, whether or not by automated means. The term is broad and encompasses virtually any handling of data, be it collection, evaluation, storage, transmission, or deletion.
