2. General information on data processing

2.1 Personal Data

Personal data is individual information about personal or factual circumstances of an identified or identifiable natural person.

Individual details about personal or factual circumstances are, for example:

  • Name, age, marital status, date of birth
  • Address, telephone number, e-mail address
  • Account number, credit card number
  • IP address & location data

2.2 This is the way we process personal data

We process personal data within the legally permissible limits. This means that data processing operations are based on a legal basis. These are standardized in Art. 6 para. 1 GDPR. Most data processing is based on a legitimate interest on our part (Art. 6 para. 1 lit. f GDPR), on processing operations necessary for the performance of the contract (Art. 6 para. 1 (lit. b GDPR) or on the basis of consent given by you (Art. 6 para. 1 lit. a GDPR). In the latter case, you will be informed separately (e.g. via a cookie banner) about the consent process.

Personal data is processed by us only for clear purposes (Art. 5 para. 1 lit. b GDPR). As soon as the purpose of the processing ceases to apply, your personal data will be deleted or protected by technical as well as organizational measures (e.g. by pseudonymization).

The same applies to the expiry of a prescribed storage period, subject to cases in which further storage is necessary for the conclusion or fulfillment of a contract. In addition, there may be a legal obligation to store data for a longer period or to pass it on to third parties (esp. to law enforcement agencies). In other cases, the storage period and type of data collected as well as the type of data processing depends on which functions you use in the individual case. We will be happy to provide you with information about this in individual cases, in accordance with Art. 15 GDPR.

2.3 We process these categories

Data categories are in particular the following data:

  • Master data (e.g. names, addresses, dates of birth),
  • Contact data (e.g. e-mail addresses, telephone numbers, messenger Services),
  • Content data (e.g. text entries, photographs, videos, contents of documents/files),
  • Contract data (e.g., subject matter of contract, terms, customer category),
  • Payment data (e.g. bank details, payment history, use of other payment Service providers),
  • Usage data (e.g. history in our Services, use of certain content, access times),
  • Connection data (e.g. device information, IP addresses, URL referrers).

2.4 These are the security measures we meet

In accordance with legal requirements and 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 your rights and freedoms, we take appropriate technical and organizational measures to ensure a level of protection appropriate to the risk.

In particular, the measures include ensuring that your data is stored and processed confidentially, with integrity and available at all times. Furthermore, the security measures we implement include controls on access to your data as well as access, input, disclosure, ensuring availability and their separation from data of other natural persons. Furthermore, we have established procedures to ensure the exercise of data subject rights (see under Section 5), the deletion of data and responses in the event of a risk to your data. Furthermore, we already consider the protection of personal data during the development of our software as well as through procedures that comply with the principle of data protection through technology design and through data protection-friendly default settings.

2.5 This is how we transfer personal data

In the course of our processing activities of your personal data, it may happen that this data is transferred or disclosed to other bodies, companies, legally independent organizational units or persons. These third parties may include, for example, payment institutions in the context of payment transactions, Service providers entrusted with IT tasks or providers of Services and content that we have integrated into our website. If we transfer or disclose your personal data to third parties, we comply with the legal requirements and, in particular, conclude appropriate contracts or agreements that serve to protect your data with the recipients of your data.

2.6 This is how a third country transfer takes place

If this privacy policy indicates that we transfer your personal data to a third country, i.e. a country outside the EU or outside the EEA, the following applies.

If we process your data in a third country or if the processing takes place in a third country as part of the use of third-party Services, this will only take place in accordance with the legal requirements.

Furthermore, a third country transfer usually only takes place with your express consent. Whether or not such consent is given, we ensure that we have contractual or legal authorization to transfer and process your data in the third country in question. Furthermore, we only allow your data to be processed by Service providers in third countries that, in our view, have a recognized level of data protection. This means that a corresponding adequacy decision exists between the EU and the country in which we transfer your personal data, for example. An “adequacy decision” is a decision adopted by the European Commission under Article 45 of the GDPR that determines that a third country (i.e., a country that is not bound by the GDPR) or an international organization provides an adequate level of protection for personal data. Alternatively, e.g. if there is no adequacy decision, a third country transfer will only take place if, for example, contractual obligations exist between us and the Service provider in the third country through so-called standard contractual clauses of the EU Commission and further technical security precautions have been taken that ensure an adequately equivalent level of protection to that in the EU or the Service provider in the third country can provide data protection certifications and your data is only processed in accordance with internal data protection regulations (Articles 44 to 49 GDPR. Information page of the EU Commission:

As part of the so-called “Data Privacy Framework” (“DPF”), the EU Commission has recognized the level of data protection for certain companies from the USA as secure within the framework of the adequacy decision of 10.07.2023. A list of certified companies and further information on the DPF can be found on the website of the US Department of Commerce at As part of this privacy policy, we will inform you which services we use are certified under the Data Privacy Framework.

2.7 Information about the cookies used (Cookies are here synonymous with other tracking mechanisms such as tokens, beacons, etc.).

Cookies are small text files that contain data from visited websites or domains and are stored on your device (computer, tablet or smartphone). If you access a service, the cookie stored on your device sends information to the party that placed the cookie.

2.7.1 First-party cookies and third-party cookies.

Our Services may set third-party cookies and allow third parties to place cookies on your device. The difference between a first party cookie and a third party cookie is the control over the placement of the cookie. First party cookies are cookies that are specific to the Services that created them. Their use allows us to provide an efficient Service and to evaluate your user behavior in our Services. Third-party cookies are placed on your device by third parties (i.e., not by us). Although we may allow third parties to access our Services to place cookies on your devices, we do not control the information provided by the cookies nor do we have access to this data. This information is processed entirely by the third parties in accordance with their respective privacy policies and, where applicable, any processing contracts entered into between us and the third parties under Article 28 GDPR or shared responsibility contracts under Article 26 GDPR.

We distinguish between

  • Functionality Cookies

These cookies are essential to provide you with Services available through our Services and to enable you to use certain features of our Services. Without these cookies, we cannot provide you certain Services on our Services.

  • Statistic cookies

These cookies are used to collect information to analyze the traffic to our Services and how visitors are using our Services. For example, these cookies may track things such as how long you spend on the Services or the pages you visit which helps us to understand how we can improve our Services site for you. The information collected through these tracking and performance cookies do not identify any individual visitor.

  • Marketing cookies

These cookies are used to show advertising that is likely to be of interest to you based on your browsing habits. These cookies, as served by our content and/or advertising providers, may combine information they collected from our Services with other information they have independently collected relating to your web browser’s activities across their network of websites. If you choose to remove or disable these targeting or advertising cookies, you will still see adverts but they may not be relevant to you.

2.7.2 How we use cookies

We want you to be able to make an informed decision for or against the use of cookies that are not strictly necessary for the technical features of the Services. Therefore, we allow you to choose which cookies you allow in a cookie consent banner when you visit our Services for the first time and permanently thereafter in appropriate settings. Here, strictly necessary cookies are mandatory for visiting our Services and are therefore already permitted via our default settings. Any other cookies are optional. You can allow them by consenting to the setting of these cookies accordingly in the cookie banner. Alternatively, you can reject them. Please note that you may be shown advertisements even if you reject.

2.7.3 Storage period of cookies

Unless we provide you with explicit information about the storage period of cookies (e.g., within the cookie banner), you can assume that the storage period can be up to two years. If cookies were set on the basis of your consent, you have the option at any time to revoke any consent you have given or to object to the processing of your data by cookie technologies (collectively referred to as “opt-out”).

2.8 Consent Management

We use Cookiebot as a consent management tool as part of the tracking and analysis activities in our services. Cookiebot is a service provided by Usercentrics A/S, Havnegade 39, 1058 Copenhagen, Denmark, phone: + 45 50 333 777, e-mail: (“Cookiebot”). Cookiebot collects log file and consent data using JavaScript. This JavaScript makes it possible to inform you about your consent to certain tags in our services and to obtain, manage and document this consent.

We process the following data: (1) Consent data (anonymized logbook data (Consent ID, Processor ID, Controller ID), Consent Status, Timestamp), (2) Device data (including shortened IP addresses (IP v4, IP v6), device information, timestamp), (3) User data (including email, ID, browser information, SettingIDs, changelog). The ConsentID (contains the above-mentioned data) and the Consent status including timestamp are stored in the local memory of your browser and at the same time on the cloud servers used by us. Further processing will only take place if you submit a request for information or revoke your consent. We also store personal data that we process using Cookiebot on our servers. The legal basis for the processing of personal data by means of Cookiebot in accordance with the provisions mentioned here results from our legitimate interest as well as for the fulfillment of legal requirements and thus from Art. 6 para. 1 lit. f and c GDPR. By means of Cookiebot, we want to comply with legal requirements for data protection and tracking and thus set up the functioning of our information technology systems in a legally compliant and user-centered manner.

3. data processing in connection with the use of our Services.

The use of our Services with all their functions involves the processing of personal data. We explain exactly how this is done here.

3.1 Informational use of our Services

The purely informational use of our Services requires the processing of the following personal data and information: Browser type and browser version, operating system used, address of previously visited websites, address of the terminal device with which you access our Services (IP address), and the time of the call to our Services. All this information is automatically transmitted by your browser if you have not configured it in such a way that transmission of the information is suppressed.

This personal data is processed for the purpose of the functionality and optimization of our Services, as well as to ensure the security of our information technology systems. These purposes are at the same time legitimate interests according to Art. 6 para. 1 lit. f GDPR, the processing is thus carried out with legal grounds.

3.2 Contact form / contacting us by e-mail

We process your personal data that you provide to us when contacting us for the purpose of answering your inquiry, your e-mail or your callback request. Processed data categories are master data, contact data, content data, possibly usage data, connection data and possibly contract data. In individual cases, we forward this data to companies affiliated with us or to third parties that we commission to process orders. The legal basis of the processing depends on the purpose of the contact. Basically, it is based on our legitimate interest and thus on Art. 6 para. 1 lit. f GDPR;  If a conclusion of a contract is to be targeted, the authorization is based on Art. 6 para. 1 lit. b GDPR.

3.3 Webhosting

3.3.1 Provision of our Services

In order to provide you with our Services, we use the Services of a web hosting provider. This hosting provider is Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Deutschland. Our Services are accessed from the servers of these web hosting providers. For these purposes, we use the web hosting provider’s infrastructure and platform Services, computing capacity, storage space and database services, as well as security services and technical maintenance services.

The processed data includes all such data that you enter or that is collected by you in the course of your use and communication in connection with your visit to our Services (e.g. your IP address). Our legal basis for using a web hosting provider to provide our Services results from Art. 6 para. 1 lit. f GDPR (legitimate interest).

3.3.2 Receiving and sending e-mails

The Services of the web host used by us may also include the sending, receiving as well as storing of e-mails. For these purposes, the addresses of the recipients of your e-mails as well as the senders as well as further information concerning the e-mail dispatch (e.g. the providers involved) as well as the contents of the respective e-mails are processed. The aforementioned data is processed, among other things, for the purpose of recognizing SPAM. E-mails are generally not sent encrypted on the Internet. As a rule, e-mails are encrypted in transit, but (unless end-to-end encryption is used) not on the servers from which they are sent and received. We can therefore not assume any responsibility for the transmission path of the e-mails between the sender and the reception on our server. Our legal basis for using a web hosting provider to receive and send e-mails results from Art. 6 para. 1 lit. f GDPR (legitimate interest).

3.3.3 Collection of access data and log files

We ourselves (or our web hosting provider) collect data on each access to the server (server log files). The server log files may include the address and name of the Services and files accessed, the date and time of access, the volume of data transferred, notification of successful access, browser type and version, your 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 (especially in the event of abusive attacks, so-called DDoS attacks) and on the other hand to ensure the utilization of the servers and their stability. Our legal basis for using a web hosting provider to collect access data and log files results from Art. 6 para. 1 lit. f GDPR (legitimate interest).

3.4 Application Management

We process your personal data that you provide to us as part of the application process (e.g. via the corresponding contact form in our services) for the purpose of processing your application and carrying out the application process. At your request, we will also consider your application in future application procedures with us or our subsidiaries. The processed data categories are master data, contact data, content data, usage data (not for postal applications), connection data (not for postal applications), contract data. The legal basis for the processing of your data in the context of applicant management is based on Art. 88 para. 1 GDPR i.V.m. § Section 26 para. 1 sentence 1 BDSG (German Federal Data Protection Act). The legal basis for applications to subsidiaries and for storage for future application procedures is Art. 6 para. 1 lit. a GDPR in conjunction with Art. 7 GDPR, § 26 para. 2 BDSG; Art. 6 para. 1 lit. f GDPR.

4. Processing on behalf

If we use external Service providers to process your data, they will be carefully selected and commissioned by us. If the Services provided by these Service providers are commissioned processing within the meaning of Art. 28 GDPR, the Service providers are bound by our instructions and are regularly monitored. In this context, our order processing contracts comply with the strict requirements of Art. 28 GDPR as well as the specifications of the German data protection authorities.

  • if you contest the accuracy of the personal data concerning you for a period enabling the controller to verify the accuracy of the personal data;
  • the processing is unlawful and you object to the erasure of the personal data and request instead the restriction of the use of the personal data;
  • the controller no longer needs the personal data for the purposes of processing, but you need them for the establishment, exercise or defense of legal claims; or

  • If the processing of personal data concerning you has been restricted, such data may – apart from being stored – only be processed with your consent or for the assertion, exercise or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or a Member State.

If the restriction of processing has been restricted in accordance with the above conditions, you will be informed by the controller before the restriction is lifted.

5.4 Right to erasure

5.4.1 You may request the controller to erase the personal data concerning you without undue delay, and the controller is obliged to erase this data without undue delay, if one of the following reasons applies:

  • The personal data concerning you are no longer necessary for the purposes for which they were collected or otherwise processed.

5.4.3 The right to erasure shall not apply to the extent that the processing is necessary

  • For the exercise of the right to freedom of expression and information;
  • for compliance with a legal obligation which requires processing under Union or Member State law to which the controller is subject, or for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;
  • for reasons of public interest in the area of public health pursuant to Art. 9 (2) lit. h and i and Art. 9 (3) GDPR;
  • for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes pursuant to Art. 89 (1) GDPR, insofar as the right referred to in (1) is likely to render impossible or seriously prejudice the achievement of the purposes of such processing; or
  • for the assertion, exercise or defense of legal claims.

5.5 Right to information

If you have asserted the right to rectification, erasure or restriction of processing against the controller, the controller is obliged to inform all recipients to whom the personal data concerning you have been disclosed of this rectification or erasure of the data or restriction of processing, unless this proves impossible or involves a disproportionate effort.

You have the right vis-à-vis the controller to be informed about these recipients.

5.6 Right to data portability

You have the right to receive the personal data concerning you that you have provided to the controller in a structured, common and machine-readable format. In addition, you have the right to transfer this data to another controller without hindrance from the controller to whom the personal data was provided, provided that

the processing is based on consent pursuant to Art. 6 (1) lit. a GDPR or Art. 9 (2) lit. a GDPR or on a contract pursuant to Art. 6 (1) lit. b GDPR and

the processing is carried out with the help of automated procedures.

In exercising this right, you also have the right to obtain that the personal data concerning you be transferred directly from one controller to another controller, insofar as this is technically feasible. Freedoms and rights of other persons must not be affected by this.

The right to data portability does not apply to processing of personal data necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

5.7 Right to object

You have the right to object at any time, on grounds relating to your particular situation, to the processing of personal data concerning you which is carried out on the basis of Article 6 (1) lit. e or f GDPR; this also applies to profiling based on these provisions.

The controller shall no longer process the personal data concerning you unless it can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or for the establishment, exercise or defense of legal claims.

If the personal data concerning you is processed for the purposes of direct marketing, you have the right to object at any time to processing of the personal data concerning you for the purposes of such marketing; this also applies to profiling, insofar as it is related to such direct marketing.

If you object to the processing for direct marketing purposes, the personal data concerning you will no longer be processed for these purposes.

You have the possibility, in connection with the use of information society Services – notwithstanding Directive 2002/58/EC – to exercise your right to object by means of automated procedures using technical specifications.

5.8 Right to revoke your declaration of consent under data protection law

You have the right to revoke your declaration of consent under data protection law at any time. The revocation of consent does not affect the lawfulness of the processing carried out on the basis of the consent until the revocation.

The processing is lawful until your revocation – the revocation thus only affects the processing after receipt of your revocation. You can declare the revocation informally by mail or e-mail. The processing of your personal data will then no longer take place, subject to permission by another legal basis. If this is not the case, your data must be deleted immediately after the revocation in accordance with Art. 17 (2) GDPR. Your right to revoke your consent subject to the above conditions is guaranteed.

Your revocation should be addressed to:

5.10 Right to complain 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 residence, place of work or the place of the alleged infringement, if you consider that the processing of personal data concerning you infringes the GDPR.

The supervisory authority to which the complaint has been lodged will inform the complainant of the status and outcome of the complaint, including the possibility of a judicial remedy under Article 78 GDPR.

6. Automated decisions in individual cases including profiling.

Automated decisions in individual cases including profiling do not take place.

7. Notification obligations of the responsible party

If your personal data have been disclosed to other recipients (third parties) with legal grounds, we will notify them of any rectification, erasure or restriction of the processing of your personal data (Art. 16, Art. 17 (1) and Art. 18 GDPR). The notification obligation does not apply if it involves disproportionate effort or is impossible. We will also inform you about the recipients upon request.
