Relevant legal bases

Relevant legal bases according to the GDPR: Below you will find an overview of the legal bases of the GDPR on the basis of 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 also apply in individual cases, we will inform you of these in the privacy policy.

  • Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR) - The data subject has given their consent to the processing of their personal data for one or more specific purposes.
  • Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR) - processing is necessary for the purposes of the legitimate interests pursued by the controller or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data.

National data protection regulations in Germany: In addition to the data protection regulations of the GDPR, national data protection regulations apply in Germany. These include, in particular, the Act on the Protection against Misuse of Personal Data in Data Processing (Federal Data Protection Act - BDSG). In particular, the BDSG contains special regulations on the right to information, the right to erasure, the right to object, the processing of special categories of personal data, processing for other purposes and transmission as well as automated decision-making in individual cases, including profiling. The data protection laws of the individual federal states may also apply.

Note on the applicability of the GDPR and Swiss FADP: This data protection notice serves to provide information in accordance with both the Swiss FADP and the General Data Protection Regulation (GDPR). For this reason, we ask you to note that the terms of the GDPR are used due to the broader geographical application and comprehensibility. In particular, instead of the terms "processing" of "personal data", "overriding interest" and "sensitive personal data" used in the Swiss DPA, the terms "processing" of "personal data", "legitimate interest" and "special categories of data" used in the GDPR are used. However, the legal meaning of the terms will continue to be determined in accordance with the Swiss DPA within the scope of application of the Swiss DPA.

Security measures

We take appropriate technical and organizational measures in accordance with the legal requirements, taking into account the state of the art, the implementation costs and the nature, scope, circumstances and purposes of the processing as well as the different probabilities of occurrence and the extent of the threat to the rights and freedoms of natural persons, in order to ensure a level of protection 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 the access, input, disclosure, safeguarding of availability and its separation. Furthermore, we have established procedures that ensure the exercise of data subject rights, the deletion of data and responses to data threats. Furthermore, we already take the protection of personal data into account during the development and selection of hardware, software and processes in accordance with the principle of data protection, through technology design and through data protection-friendly default settings.

Securing online connections using TLS/SSL encryption technology (HTTPS): To protect user data transmitted via our online services from unauthorized access, we use 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 app and the user's browser (or between two servers), protecting the data from unauthorized access. TLS, as the more advanced and secure version of SSL, ensures that all data transmissions meet the highest security standards. If a website is secured by an SSL/TLS certificate, this is signaled by the display of HTTPS in the URL. This serves as an indicator to users that their data is being transmitted securely and encrypted.

Transmission of personal data

As part of our processing of personal data, it may be transmitted to other bodies, companies, legally independent organizational units or persons or disclosed to them. The recipients of this data may include, for example, service providers commissioned with IT tasks or providers of services and content that are integrated into a website. In such cases, we observe the legal requirements and, in particular, conclude corresponding contracts or agreements with the recipients of your data that serve to protect 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 the use of third-party services or the disclosure or transfer of data to other persons, bodies or companies (which can be recognized by the postal address of the respective provider or if the data protection declaration expressly refers to the transfer of data to third countries), this is always done in accordance with the legal requirements.

For data transfers to the USA, we rely primarily on the Data Privacy Framework (DPF), which was recognized as a secure legal framework by an adequacy decision of the EU Commission on 10.07.2023. In addition, we have concluded standard contractual clauses with the respective providers that comply with the requirements of the EU Commission and define contractual obligations to protect your data.

This dual protection ensures comprehensive protection of your data: The DPF forms the primary layer of protection, while the Standard Contractual Clauses serve as additional security. Should there be any changes to the DPF, the standard contractual clauses act as a reliable fall-back option. In this way, we ensure that your data always remains adequately protected, even in the event of any political or legal changes.

For the individual service providers, we will inform you whether they are certified in accordance with 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, appropriate security measures 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?prefLang=de.

General information on data storage and deletion

We delete personal data that we process in accordance with the statutory provisions as soon as the underlying consents are revoked or there is no further legal basis for the processing. This applies to cases in which the original purpose of processing no longer applies or the data is no longer required. Exceptions to this rule exist if legal obligations or special interests require longer storage or archiving of the data.

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

Our data protection information contains additional information on the retention and deletion of data that applies specifically to certain processing operations.

If there is more than one indication of the retention period or deletion period for a date, the longest period is always decisive. We only process data that is no longer stored for the originally intended purpose, but due to legal requirements or other reasons, for the reasons that justify its storage.

Retention and deletion of data: The following general time limits apply to retention and archiving under German law:

  • 10 years - Retention period for books and records, annual financial statements, inventories, management reports, opening balance sheet as well as the work instructions and other organizational documents required for their understanding (§ 147 para. 1 no. 1 in conjunction with para. 3 AO, § 14b para. Para. 3 AO, § 14b Para. 1 UStG, § 257 Para. 1 No. 1 i.V.m. para. 4 HGB).
  • 8 years - Accounting documents, such as invoices and expense receipts (§ 147 para. 1 no. 4 and 4a in conjunction with para. para. 3 sentence 1 AO and § 257 para. 1 no. 4 in conjunction with para. para. 4 HGB).
  • 6 years - Other business documents: commercial or business letters received, reproductions of commercial or business letters sent, other documents, insofar as they are relevant for taxation, e.g. time sheets, company accounting sheets, calculation documents, price labels, but also payroll accounting documents, insofar as they are not already accounting documents and cash register slips (Section 147 (1) nos. 2, 3, 5 in conjunction with (3) AO). Para. 3 AO, § 257 Para. 1 No. 2 and 3 in conjunction with Para. para. 4 HGB).
  • 3 years - Data required to consider potential warranty and compensation claims or similar contractual claims and rights and to process related inquiries based on past business experience and standard industry practices will be stored for the duration of the regular statutory limitation period of three years (§§ 195, 199 BGB).

Period begins at the end of the year: If a period does not expressly begin on a specific date and is 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 date on which the termination or other termination of the legal relationship takes effect.

Rights of the data subjects

Rights of data subjects under the GDPR: As a data subject, you are entitled to various rights under the GDPR, which arise in particular from Art. 15 to 21 GDPR:

  • Right to object: You have the right to object, on grounds relating to your particular situation, at any time to processing of personal data concerning you which is based on point (e) or (f) of Article 6(1) GDPR, including profiling based on those provisions. If the personal data concerning you are 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, which includes profiling to the extent that it is related to such direct marketing.
  • Right to withdraw consent: You have the right to withdraw your consent at any time.
  • Right of access: You have the right to obtain confirmation as to whether or not personal data concerning you is being processed and to obtain information about this data as well as further information and a copy of the data in accordance with the legal requirements.
  • Right to rectification: In accordance with the statutory provisions, you have the right to request the completion of data concerning you or the rectification of inaccurate data concerning you.
  • Right to erasure and restriction of processing: In accordance with the statutory provisions, you have the right to demand that data concerning you 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 the 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: In accordance with the statutory provisions 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 in which you are habitually resident, the supervisory authority of your place of work or the place of the alleged infringement, if you consider that the processing of personal data relating to you infringes the GDPR.

Provision of the online offer and web hosting

We process users' data in order to provide them with our online services. For this purpose, we process the user's IP address, which is necessary to transmit the content and functions of our online services to the user's browser or end device.

  • Processed data types: Usage data (e.g. page views and length of stay, click paths, intensity and frequency of use, device types and operating systems used, interactions with content and functions); metadata, communication data and process data (e.g. IP addresses, time data, identification numbers, persons involved); log data (e.g. log files relating to logins or the retrieval of data or access times). Content data (e.g. text or image messages and contributions as well as the information relating to them, such as information on authorship or time of creation).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Purposes of processing: Provision of our online offer and user-friendliness; information technology infrastructure (operation and provision of information systems and technical devices (computers, servers, etc.)). Security measures.
  • Storage and deletion: Deletion in accordance with the information in the section "General information on data storage and deletion".
  • Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).

Further information on processing operations, procedures and services:

  • Provision of online offer on rented storage space: For the provision of our online offer, we use storage space, computing capacity and software that we rent or otherwise obtain from a corresponding server provider (also called "web host"); legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).
  • Provision of online offer on own/ dedicated server hardware: For the provision of our online offer, we use server hardware operated by us as well as the associated storage space, computing capacity and software; legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. 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". The server log files may include the address and name of the web pages and files accessed, date and time of access, data volumes 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 can be used for security purposes, e.g. to avoid overloading the servers (especially in the event of abusive attacks, so-called DDoS attacks), and to ensure the utilization of the servers and their stability; legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR). Deletion of data: Log file information is stored for a maximum of 30 days and then deleted or anonymized. Data whose further storage is required for evidentiary purposes is excluded from deletion until the respective incident has been finally clarified.
  • E-mail dispatch and hosting: The web hosting services we use also include the dispatch, receipt and storage of e-mails. For these purposes, the addresses of the recipients and senders as well as other information relating to the sending of e-mails (e.g. the providers involved) and the content of the respective e-mails are processed. The aforementioned data may also be processed for the purpose of detecting SPAM. Please note that e-mails on the Internet are generally not sent in encrypted form. As a rule, emails are encrypted in transit, but not on the servers from which they are sent and received (unless an end-to-end encryption method is used). We can therefore assume no responsibility for the transmission path of the emails between the sender and receipt on our server; legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).

Use of cookies

The term "cookies" refers to functions that store information on users' end devices and read it from them. Cookies can also be used for various purposes, for example to ensure the functionality, security and convenience of online services and to analyze visitor flows. We use cookies in accordance with the statutory provisions. If necessary, we obtain the user's consent in advance. If consent is not required, we rely on our legitimate interests. This applies if the storage and reading of information is essential in order to be able to provide expressly requested content and functions. This includes, for example, saving settings and ensuring the functionality and security of our online offering. Consent can be revoked at any time. We provide clear information about the scope and which cookies are used.

Information on legal bases under data protection law: Whether we process personal data using cookies depends on consent. If 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.

Storage period: With regard to the storage period, a distinction is made between the following types of cookies:

  • Temporary cookies (also: session cookies): Temporary cookies are deleted at the latest after a user has left an online service and closed their end device (e.g. browser or mobile application).
  • Permanent cookies: Permanent cookies remain stored even after the end device is closed. For example, the log-in status can be saved and preferred content can be displayed directly when the user visits a website again. The user data collected with the help of cookies can also be used to measure reach. If we do not provide users with explicit information on the type and storage duration of cookies (e.g. when obtaining consent), they should assume that they are permanent and that they may be stored for up to two years.

General information on revocation and objection (opt-out): Users can revoke the consents they have given at any time and also declare an objection to the processing in accordance with the legal requirements, also by means of the privacy settings of their browser.

  • Processed data types: Meta, communication and process data (e.g. IP addresses, time data, identification numbers, persons involved).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Legal bases: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR). Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR).

Further information on processing operations, procedures and services:

  • Processing of cookie data on the basis of consent: We use a consent management solution in which user consent is obtained for the use of cookies or for the procedures and providers mentioned in the consent management solution. This procedure is used to obtain, log, manage and revoke consent, in particular with regard to the use of cookies and comparable technologies that are used to store, read and process information on users' end devices. As part of this procedure, user consent is obtained for the use of cookies and the associated processing of information, including the specific processing and providers mentioned in the consent management procedure. Users also have the option of managing and revoking their consent. The declarations of consent are stored in order to avoid repeated queries and to be able to provide proof of consent in accordance with legal requirements. The 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 the consent to a specific user or their device. If no specific information on the providers of consent management services is available, the following general information applies: Consent is stored for up to two years. A pseudonymous user identifier is created, which is stored together with the time of consent, information on the scope of consent (e.g. relevant categories of cookies and/or service providers) and information on the browser, the system and the end device used; legal basis: consent (Art. 6 para. 1 sentence 1 lit. a) GDPR).
  • BorlabsCookie: Consent management: Process for obtaining, logging, managing and revoking consent, in particular for the use of cookies and similar technologies for storing, reading and processing information on users' end devices and their processing; Service provider: Execution on servers and/or computers under its own responsibility under data protection law; Website: https://de.borlabs.io/borlabs-cookie/. Further information: An individual user ID, language and types of consent and the time of their submission are stored on the server and in the cookie on the user's device.

Blogs and publication media

We use blogs or comparable means of online communication and publication (hereinafter "publication medium"). Readers' data is only 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. In addition, we refer to the information on the processing of visitors to our publication medium in the context of this data protection notice.

  • Processed data types: Inventory data (e.g. full name, residential address, contact information, customer number, etc.); Contact data (e.g. postal and email addresses or telephone numbers); Content data (e.g. text or image messages and contributions as well as the information relating to them, such as information on authorship or time of creation); Usage data (e.g. page views and length of stay, click paths, intensity and frequency of use, device types and operating systems used, interactions with content and functions). Meta, communication and process data (e.g. IP addresses, time data, identification numbers, persons involved).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Purposes of Processing: Feedback (e.g. collecting feedback via online form); Provision of our online services and usability; Security measures; Communication. Organizational and administrative procedures.
  • Storage and deletion: Deletion in accordance with the information in the section "General information on data storage and deletion".
  • Legal bases: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR). Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR).

Further information on processing operations, procedures and services:

  • Comments and contributions: When users leave comments or other contributions, their IP addresses may be stored on the basis of our legitimate interests. This is done for our security in case someone leaves illegal content in comments and posts (insults, prohibited political propaganda, etc.). In this case, we ourselves may be prosecuted for the comment or post and are therefore interested in the identity of the author.

    Furthermore, we reserve the right to process user data for the purpose of spam detection on the basis of our legitimate interests.

    On the same legal basis, we reserve the right to store the IP addresses of users for the duration of surveys and to use cookies in order to avoid multiple votes.

    The personal information provided in the comments and contributions, any contact and website information as well as the content information will be permanently stored by us until the user objects; legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).
  • Comment subscriptions: Users can subscribe to the follow-up comments with their consent. Users will receive a confirmation email to verify that they are the owner of the email address entered. Users can unsubscribe from ongoing comment subscriptions at any time. The confirmation email will contain information on how to unsubscribe. For the purposes of proving the user's consent, we store the time of registration together with the user's IP address and delete this information when users unsubscribe from the subscription.

    You can cancel your subscription at any time, i.e. revoke your consent. We may store the unsubscribed e-mail addresses for up to three years on the basis of our legitimate interests before deleting them in order to be able to prove that consent was previously given. The processing of this data is limited to the purpose of a possible defense against claims. An individual request for deletion is possible at any time, provided that the former existence of consent is confirmed at the same time; legal basis: Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR).
  • Retrieval of WordPress emojis and smilies: Retrieval of WordPress emojis and smilies - Graphic emojis (or smilies), i.e. small graphic files that express feelings, are used within our WordPress blog for the purpose of efficient integration of content elements, obtained from external servers. The providers of the servers collect the IP addresses of the users. This is necessary so that the emoji files can be transmitted to the users' browsers; service provider: Aut O'Mattic A8C Ireland Ltd, Grand Canal Dock, 25 Herbert Pl, Dublin, D02 AY86, Ireland; Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR); Website: https://automattic.com; Privacy Policy: https://automattic.com/privacy; Data processing agreement: Provided by the service provider. Basis for third country transfers: Data Privacy Framework (DPF), standard contractual clauses (provided by the service provider).
  • Akismet anti-spam check: Akismet anti-spam check - We use the "Akismet" service on the basis of our legitimate interests. With the help of Akismet, comments from real people are distinguished from spam comments. For this purpose, all comments are sent to a server in the USA, where they are analyzed and stored for four days for comparison purposes. If a comment has been classified as spam, the data is stored beyond this period. This data includes the name entered, the e-mail address, the IP address, the comment content, the referrer, details of the browser used and the computer system and the time of the entry.

    Users are welcome to use pseudonyms or refrain from entering their name or email address. You can completely prevent the transfer of data by not using our comment system. That would be a shame, but unfortunately we do not see any alternatives that work just as effectively; Service provider: Aut O'Mattic A8C Ireland Ltd, Grand Canal Dock, 25 Herbert Pl, Dublin, D02 AY86, Ireland; Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR); Website: https://automattic.com; Privacy Policy: https://automattic.com/privacy/; Data processing agreement: Provided by the service provider. Basis for third country transfers: Data Privacy Framework (DPF), standard contractual clauses (provided by the service provider).
  • Profile pictures from Gravatar: Profile pictures - We use the Gravatar service within our online offering and in particular in the blog.

    Gravatar is a service where users can register and store profile pictures and their email addresses. If users leave posts or comments on other online presences (especially in blogs) with the respective e-mail address, their profile pictures can be displayed next to the posts or comments. For this purpose, the e-mail address provided by the users is transmitted to Gravatar in encrypted form for the purpose of checking whether a profile is stored for it. This is the sole purpose of transmitting the e-mail address. It will not be used for any other purpose and will be deleted afterwards.

    The use of Gravatar is based on our legitimate interests, as we use Gravatar to offer post and comment authors the opportunity to personalize their posts with a profile picture.

    By displaying the images, Gravatar learns the IP address of the user, as this is necessary for communication between a browser and an online service.

    If users do not want a user picture linked to their email address at Gravatar to appear in the comments, they should use an email address that is not stored at Gravatar to comment. We would also like to point out that it is also possible to use an anonymous e-mail address or no e-mail address at all if users do not wish their own e-mail address to be sent to Gravatar. Users can completely prevent the transmission of data by not using our commenting system; service provider: Aut O'Mattic A8C Ireland Ltd, Grand Canal Dock, 25 Herbert Pl, Dublin, D02 AY86, Ireland; Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR); Website: https://automattic.com; Privacy Policy: https://automattic.com/privacy; Data processing agreement: Provided by the service provider. Basis for third country transfers: Data Privacy Framework (DPF), standard contractual clauses (provided by the service provider).

Web analysis, monitoring and optimization

Web analysis (also referred to as "reach measurement") is used to evaluate the flow of visitors to our online offering and may include behavior, interests or demographic information about visitors, such as age or gender, as pseudonymous values. With the help of reach analysis, we can, for example, recognize at what time our online offer or its functions or content are most frequently used, or invite visitors to reuse them. It also enables us to understand which areas require optimization.

In addition to web analysis, we may also use test procedures, for example to test and optimize different versions of our online offering or its components.

Unless otherwise stated below, profiles, i.e. data summarized for a usage process, can be created for these purposes and information can be stored in a browser or end device and then read out. The information collected includes, in particular, websites visited and the elements used there as well as technical information such as the browser used, the computer system used and information on usage times. If users have consented to the collection of their location data from us or from the providers of the services we use, it is also possible to process location data.

In addition, the IP addresses of users are stored. However, we use an IP masking procedure (i.e. pseudonymization by shortening the IP address) to protect users. In general, no clear user data (such as e-mail addresses or names) is stored in the context of web analysis, A/B testing and optimization, but pseudonyms. This means that neither we nor the providers of the software used know the actual identity of the users, but only the information stored in their profiles for the purpose of the respective process.

Notes on legal bases: If 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, economical and recipient-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.

  • Processed data types: Usage data (e.g. page views and dwell time, click paths, intensity and frequency of use, device types and operating systems used, interactions with content and functions). Meta, communication and process data (e.g. IP addresses, time data, identification numbers, persons involved).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Purposes of processing: Reach measurement (e.g. access statistics, recognition of returning visitors); profiles with user-related information (creation of user profiles). Provision of our online services and user-friendliness.
  • Storage and deletion: Deletion in accordance with the information in the section "General information on data storage 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 (Art. 6 para. 1 sentence 1 lit. a) GDPR). Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).

Further information on processing operations, procedures and services:

  • Google Tag Manager: We use Google Tag Manager, a tool from Google, to manage so-called website tags centrally via a user interface. Tags are small code elements on our website that are used, among other things, to measure and analyze visitor activity. This technology helps us to improve our website and the services offered on it. The Google Tag Manager itself does not create any user profiles, does not store any cookies and does not carry out any independent analyses. It merely serves to integrate the tools and services that we use for our website more easily and efficiently. Nevertheless, when Google Tag Manager is used, the user's IP address is transmitted to Google, which is technically necessary in order to perform the various services we use. It is important to know that this data processing only takes place if services are integrated via the Tag Manager that require this. For details on these services and how they process data, please refer to the further sections in this privacy policy; Service provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland; Legal basis: Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR); Website: https://marketingplatform.google.com; Privacy Policy: https://policies.google.com/privacy; Data processing agreement: https://business.safety.google/adsprocessorterms/; Basis for third country transfers: Data Privacy Framework (DPF), Standard Contractual Clauses(https://business.safety.google/adsprocessorterms).

  • Google Tag Manager (server-side use): Google Tag Manager is an application with which we can manage so-called website tags via an interface and thus integrate other services into our online offering (see also the further information in this privacy policy). The Tag Manager itself (which implements the tags) does not store any user profiles or cookies. The other services are integrated on the server side. This means that user data is not transmitted directly from their end device to the respective service or Google. In particular, the user's IP address is not transmitted to the other service. Instead, the data is first transmitted to our server, where the user's data records are assigned to our internal user identification number. The subsequent transmission of the data from our server to the servers of the respective service providers only takes place in this pseudonymized form. The user identification number does not contain any unique data, such as names or email addresses; service provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland; Legal basis: Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR); Website: https://marketingplatform.google.com/intl/de/about/analytics/; Privacy Policy: https://policies.google.com/privacy; Data processing agreement: https://business.safety.google/adsprocessorterms/; Basis for third country transfers: Data Privacy Framework (DPF), Standard Contractual Clauses(https://business.safety.google/adsprocessorterms//).

Presence 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 result in risks for users because, for example, it could make it more difficult to enforce user rights.

Furthermore, user data within social networks is generally processed for market research and advertising purposes. For example, user profiles can be created based on user behavior and the resulting interests of users. The latter may in turn be used, for example, to place advertisements within and outside the networks that presumably correspond to the interests of the users. Cookies are therefore generally stored on the user's computer, in which the user's usage behavior and interests are stored. In addition, data can also be stored in the user profiles independently of the devices used by the users (especially if they are members of the respective platforms and are logged in there).

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

In the case of requests for information and the assertion of data subject rights, we would also like to point out that these can be asserted most effectively with the providers. Only the latter have access to the user data and can take appropriate measures and provide information directly. If you still need help, you can contact us.

  • Processed data types: Contact data (e.g. postal and email addresses or telephone numbers); Content data (e.g. text or image messages and contributions as well as the information relating to them, such as information on authorship or time of creation). Usage data (e.g. page views and length of stay, click paths, intensity and frequency of use, device types and operating systems used, interactions with content and functions).
  • Data subjects: Users (e.g. website visitors, users of online services).
  • Purposes of processing: Communication; feedback (e.g. collecting feedback via online form). Public relations.
  • Storage and deletion: Deletion in accordance with the information in the section "General information on data storage and deletion".
  • Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR).

Plug-ins and embedded functions and content

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

The integration always requires that the third-party providers of this content process the IP address of the user, as they would not be able to send the content to their browser without the IP address. The IP address is therefore required to display this content or function. We endeavor to only use content whose respective providers only use the IP address to deliver the content. Third-party providers may also use so-called pixel tags (invisible graphics, also known as "web beacons") for statistical or marketing purposes. Pixel tags can be used to analyze 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 contain, among other things, technical information about the browser and operating system, referring websites, time of visit and other information about the use of our online offer, but may also be linked to such information from other sources.

Notes on legal bases: If we ask users for their consent to the use of third-party providers, the legal basis for data processing is permission. Otherwise, user data is processed on the basis of our legitimate interests (i.e. interest in efficient, economical and recipient-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.

  • Processed data types: Usage data (e.g. page views and dwell time, click paths, intensity and frequency of use, device types and operating systems used, interactions with content and functions); meta, communication and process data (e.g. IP addresses, time data, identification numbers, persons involved).

Definitions of terms

This section provides you with an overview of the terms used in this privacy policy. Insofar as the terms are defined by law, their legal definitions apply. The following explanations, on the other hand, are primarily intended to aid understanding.

  • Inventory data: Inventory data includes essential information that is necessary for the identification and management of contractual partners, user accounts, profiles and similar assignments. This data may include personal and demographic information such as names, contact information (addresses, telephone numbers, e-mail addresses), dates of birth and specific identifiers (user IDs). Inventory data forms the basis for any formal interaction between people and services, facilities or systems by enabling clear assignment and communication.
  • Content data: Content data includes information generated in the course of creating, editing and publishing content of all kinds. This category of data can include text, 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 details: Contact data is essential information that enables communication with individuals or organizations. It includes telephone numbers, postal addresses and email addresses, as well as communication tools 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 way in which data is processed, transmitted and managed. Meta data, also known as data about data, includes information that describes the context, origin and structure of other data. It can include information on file size, creation date, the author of a document and change histories. Communication data records the exchange of information between users via various channels, such as e-mail traffic, call logs, messages in social networks and chat histories, including the persons involved, time stamps and transmission paths. Procedural data describes the processes and procedures within systems or organizations, including workflow documentation, logs of transactions and activities, and audit logs used to track and review operations.
  • Usage data: Usage data refers to information that captures how users interact with digital products, services or platforms. This data includes a wide range of information that shows how users use applications, which functions they prefer, how long they stay on certain pages and which paths they navigate through an application. Usage data can also include frequency of use, timestamps of activities, IP addresses, device information and location data. It is particularly valuable for analysing user behaviour, optimizing user experiences, personalizing content and improving products or services. In addition, 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 referred to as "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. a 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, includes any type of automated processing of personal data that consists of using this personal data to analyze, evaluate or predict certain personal aspects relating to a natural person (depending on the type of profiling, this may include various information relating to demographics, behavior and interests, such as interaction with websites and their content, etc.) (e.g. interests in certain content or products, click behavior on a website or location). Cookies and web beacons are often used for profiling purposes.
  • Log data: Log data is information about events or activities that have been logged on 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 to analyze system problems, for security monitoring or to create performance reports.
  • Reach measurement: Reach measurement (also known as web analytics) is used to evaluate the flow of visitors to an online offering and can include the behavior or interests of visitors in certain information, such as website content. With the help of reach analysis, operators of online offers can, for example, recognize at what time users visit their websites and what content they are interested in. This allows them to better adapt the content of their websites to the needs of their visitors, for example. Pseudonymous cookies and web beacons are often used for reach analysis purposes in order to recognize returning visitors and thus obtain more precise analyses of the use of an online offering.
  • Location data: Location data is generated when a mobile device (or another device with the technical requirements for location determination) connects to a radio cell, a WLAN or similar technical means and functions of location determination. Location data is used to indicate the geographically determinable position on earth at which the respective device is located. Location data can be used, for example, to display map functions or other location-dependent information.
  • Controller: The "controller" is 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 covers practically every handling of data, be it collection, analysis, storage, transmission or deletion.
