Our company as responsible party for processing has implemented numerous technical and organizational measures to ensure the most complete protection of the personal data processed via this website. Nevertheless, Internet-based data transmissions can generally have security holes, so that an absolute protection cannot be guaranteed. For this reason, every person concerned is free to transmit personal data to us in alternative ways, for example by telephone.
Our company is part of the InfraServ Wiesbaden group, consisting of the following companies that are legally independent of each other:
InfraServ GmbH & Co. Wiesbaden KG, Wiesbaden, Germany
InfraServ Wiesbaden Technik GmbH & Co. KG, Wiesbaden, Germany
GES Systemhaus GmbH & Co. KG, Wiesbaden, Germany
In order to process your inquiry, it may be necessary for us to pass on data and, possibly, personal data within the group of companies and process them for specific purposes.
We would also like to inform you that our company regularly reviews the creditworthiness for the conclusions of contracts and, in certain cases, even for existing customers, where there is a legitimate interest. For this purpose, we cooperate with Creditreform Boniversum GmbH, Hellersbergstraße 11, 41460 Neuss, from which we receive the necessary data. Please pay attention to the following information of Boniversum GmbH regarding data protection according to the EU GDPR against this background:
a) Personal data
Personal data is any information relating to an identified or identifiable natural person (hereinafter the "person concerned"). A natural person is considered to be identifiable, when they can be identified directly or indirectly, in particular by association with an identifier such as a name, an identification number, location data, an online identifier or one or more special features, expressing the physical, physiological, genetic, mental, economic, cultural or social identity of this natural person.
b) Person concerned
A person concerned is any identified or identifiable natural person whose personal data is processed by the person responsible for processing.
Processing means any process or any such series of operations in connection with personal data with or without the aid of automated procedures, such as collecting, entering, organizing, arranging, storing, adapting or modifying, reading out, querying, using, disclosing by transmission, distribution or any other form of provision, matching or linking, restriction, deletion or destruction.
d) Restriction of processing
Restriction of processing is the marking of stored personal data with the aim of limiting their future processing.
Profiling is any kind of automated processing of personal data that consists of using this personal information to assess, analyze or predict certain personal aspects relating to a natural person, in particular aspects relating to job performance, economic situation, health, personal preferences, interests, reliability, behavior, whereabouts or relocation of that natural person.
Pseudonymization is the processing of personal data in such a way that personal data can no longer be attributed to a person concerned without the enlistment of additional information, provided that such additional information is kept separately and is subject to technical and organizational measures to ensure that the personal data are not assigned to an identified or identifiable natural person.
g) Party responsible or person responsible for processing
The party responsible or person responsible for processing is the natural or legal person, public authority, institution or other body that, alone or together with others, decides on the purposes and means of processing of personal data. If the purposes and means of such processing are provided under European Union law or under the law of the member states, the party responsible or the specific criteria for their designation may be provided for under European Union or national law.
h) Data processor
The data processor is a natural or legal person, public authority, institution or other body that processes personal data on behalf of the party responsible.
The recipient is a natural or legal person, public authority, institution or other body to whom personal data are disclosed, whether or not it is a third party. Public authorities that may receive personal data under a particular investigation mission under European Union or under national law, however, are not considered recipients.
j) Third party
A third party is a natural or legal person, public authority, institution or body other than the person concerned, the party responsible, the data processor, and the persons authorized under the direct responsibility of the party responsible or the data processor to process the personal data.
Consent is any voluntarily given and unambiguously expressed confirmatory act in the form of a well-informed statement or any other unambiguously confirming action by the person concerned, by which the person concerned indicates that they consent to the processing of the personal data concerning them.
The party responsible within the meaning of the General Data Protection Regulation, other data protection laws in the member states of the European Union, and other regulations of data protection character is:InfraServ GmbH & Co. Wiesbaden KG
Kasteler Straße 45
The data protection commissioner of the responsible party for processing is:Mr. Michael Suess
InfraServ GmbH & Co. Wiesbaden KG
Kasteler Straße 45
Tel.: 0049 611 9626130
Any person concerned can at any time contact our data protection commissioner directly regarding any questions and suggestions for data protection.
Our website records a number of general data and information each time the website is accessed by a person concerned or an automated system. These general data and information are stored in the log files of the server. The following data can be recorded: (1) browser types and versions used, (2) the operating system used by the accessing system, (3) the internet page from which an accessing system accesses our website (so-called referrers), (4) the subpages which are accessed via an accessing system on our website, (5) the date and time of an access to the website, (6) an Internet Protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) other similar data and information serving to avert danger in the event of attacks on our information technology systems. When using these general data and information, we draw no conclusions about the person concerned. Rather, this information is required to (1) correctly deliver the contents of our website, (2) to optimize the content of our website and to advertise it, (3) to ensure the continued functioning of our information technology systems and the technology of our website, and (4) to provide law enforcement authorities with the information necessary for law enforcement in the event of a cyberattack. These anonymously collected data and information are therefore statistically assessed by us on the one hand, and furthermore with the aim of increasing data protection and data security in our company in order to ultimately ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a person concerned.

The website operator has a legitimate interest in the storage of cookies for the technically error-free and optimized provision of their services.
The person responsible for processing processes and stores the personal data of the person concerned only for the period necessary to achieve the purpose of the storage, or if so required by the European issuer of directives and regulations or by another issuer of directives and regulations the person responsible for processing is subject to. If the purpose of the storage ceases to exist or if a storage period prescribed by the European issuer of directives and regulations or any other relevant legislative authority expires, the personal data will be routinely blocked or deleted in accordance with the statutory provisions.
a) Right to confirmation
Each person concerned has the right, as conceded by the European issuer of directives and regulations, to demand from the party/person responsible for processing to confirm whether personal data relating to them are being processed.

- Furthermore, the person concerned has a right to information as to whether personal data have been transmitted to a third country or to an international organization. If that is the case, the person concerned incidentally has the right to obtain information about the appropriate guarantees in connection with the transmission.

c) Right to correction
Any person concerned by the processing of personal data has the right, conceded by the European issuer of directives and regulations, to demand the immediate correction of inaccurate personal data concerning them. Furthermore, the person concerned has the right to demand the completion of incomplete personal data – including by means of a supplementary declaration – considering the purposes of processing. If a person concerned wishes to exercise this right to correction, they may contact an employee of the person responsible for processing at any time.
d) Right to deletion (right to be forgotten)
Any person concerned by the processing of personal data shall have the right, conceded by the European issuer of directives and regulations, to demand from the party responsible to immediately delete the personal data concerning them, provided that one of the following reasons applies and as far as the processing thereof is not required:
- The personal data have been collected for such purposes or processed in any way for which they are no longer necessary.
- The person concerned revokes their consent, on which the processing was based pursuant to Art. 6 para. 1 lit. a GDPR or Art. 9 para. 2 lit. a GDPR, and there is a lack of any other legal basis for the processing.
- The person concerned submits an objection to the processing pursuant to Art. 21 para. 1 GDPR, and there are no paramount legitimate reasons for the processing, or the person concerned submits an objection pursuant to Art. 21 para. 2 GDPR against the processing.
The personal data were processed unlawfully.
- The deletion of personal data is required to fulfill a legal obligation under European Union law or under the law of the member states to which the party responsible is subject.
- The personal data were collected in relation to information company services offered pursuant to Art. 8 para. 1 GDPR.
If any of the above reasons apply and a person concerned wishes to arrange for the deletion of personal data stored by us, they may, for this reason, contact an employee of the person responsible for processing at any time. The employee will arrange for the deletion request to be fulfilled immediately. If the personal data have been made public by us and if our company is obligated to delete the personal data as the body responsible pursuant to Art. 17 para. 1 GDPR, we shall take appropriate measures, including technical ones, considering the available technology and the implementation costs, to inform other persons responsible for data processing who are processing the published personal data that the person concerned has requested that these other persons responsible for data processing delete all links to such personal data or delete copies or replications of such personal data, as far as the processing thereof is not required. Our employee will arrange for the necessary actions in individual cases.
e) Right to restriction of processing
Any person concerned by the processing of personal data has the right, conceded by the European issuer of directives and regulations, to demand from the person responsible to restrict the processing if one of the following conditions applies:
- The accuracy of the personal data is contested by the person concerned, namely for a period of time that enables the person responsible to verify the accuracy of the personal data.
- The processing is unlawful; the person concerned refuses the deletion of the personal data and instead demands the restriction of the use of personal data.
- The person responsible no longer needs the personal data for the purposes of processing, but the person concerned requires them to enforce, exercise or defend their rights.
- The person concerned has submitted an objection to the processing pursuant to Art. 21 para. 1 GDPR, and it is not yet clear whether the legitimate reasons of the person responsible outweigh those of the person concerned.
If one of the above conditions is given and a person concerned wishes to request the restriction of personal data stored by us, they may contact an employee of the person responsible for processing at any time. Our employee will arrange for the restriction of processing.
f) Right to data transferability
Any person concerned by the processing of personal data shall have the right, conceded by the European issuer of directives and regulations, to obtain the personal data concerning them provided to a person responsible by the person concerned in a structured, common and machine-readable format. They also have the right to transmit these data to another person responsible without hindrance by the person responsible to whom the personal data had been provided, provided that the processing is based on the consent pursuant to Art. 6 para. 1 lit. a GDPR or Art. 9 para. 2 lit. a GDPR or is based on a contract pursuant to Art. 6 para. 1 lit. b GDPR and the processing is carried out by automated means, unless the processing is necessary for the performance of a task of public interest or the exertion of public authority which had been transferred to the person responsible. Furthermore, in exercising their right to data transferability under Art. 20 para. 1 GDPR, the person concerned has the right to demand the personal data transmission directly from one person responsible to another person responsible, provided that this is technically feasible and provided that this does not affect the rights and freedoms of other persons. To enforce the right to data transferability, the person concerned may contact one of our employees at any time.
g) Right to objection
Any person concerned by the processing of personal data shall have the right, conceded by the European issuer of directives and regulations, to submit an objection, for reasons arising from their particular situation, against the processing of personal data relating to them pursuant to Art. 6 para. 1 lit. e or lit. f GDPR at any time. This also applies to profiling based on these provisions. In the event of an objection, we will no longer process personal data unless we can establish compelling grounds requiring protection for processing that outweigh the interests, rights and freedoms of the person concerned or the processing serves the purpose of enforcing, exercising or defending legal claims. If we process the personal data in order to carry out direct mail, the person concerned has the right to object at any time to the processing of the personal data for the purpose of such advertising. This also applies to profiling, as far as it is associated with such direct mail. If the person concerned objects to our processing for direct marketing purposes, we will no longer process the personal data for these purposes. In addition, the person concerned has the right, for reasons that arise from their particular situation, to submit an objection against the processing of personal data concerning them, which in our case are scientific or historical research purposes or statistical purposes pursuant to Art. 89 para. 1 GDPR, unless such processing is necessary to fulfill a task of public interest. In order to exercise the right to objection, the person concerned can directly contact any employee . The person concerned is also free to exercise their right to objection by means of automated procedures using technical specifications in connection with the use of the information company services, regardless of the directive 2002/58/EG.
h) Automated decisions in individual cases including profiling
Any person concerned by the processing of personal data shall have the right, as conceded by the European issuer of directives and regulations, not to be subject to a decision based exclusively on automated processing – including profiling – which has a legal effect on them or, in a similar manner, significantly affects them; unless the decision (1) is necessary for the conclusion or fulfillment of a contract between the person concerned and the person responsible or (2) it is permitted by European Union or member state regulations to which the person responsible is subject and such regulations contain appropriate measures to safeguard the rights, freedoms, and legitimate interests of the person concerned or (3) takes place with the express consent of the person concerned. If the decision (1) is required for the conclusion or fulfillment of a contract between the person concerned and the person responsible or (2) it takes place with the express consent of the person concerned, we shall take appropriate measures to safeguard the rights, freedoms, and legitimate interests of the person concerned, including at least the right to obtain the intervention of a person on the part of the person responsible, to express their own position and to contest the decision. If the person concerned wishes to claim automated decision-making rights, they can contact an employee of the person responsible for processing at any time.
i)Right of revocation of a data protection consent
Any person concerned by the processing of personal data has the right, conceded by the European issuer of directives and regulations, to revoke a consent to the processing of personal data at any time. If the person concerned wishes to enforce their right to revoke a consent, they may contact an employee of the person responsible for processing at any time.
The person responsible for processing collects and processes the personal data of applicants for the purpose of carrying out the application process. The processing can also be done electronically. This is particularly the case when an applicant submits corresponding application documents to the person responsible for processing by electronic means, for example by e-mail or via a web form available on the website. If the person responsible for processing concludes a contract of employment with an applicant, the data transmitted will be stored for the purpose of execution of the employment relationship in accordance with the law. If no contract of employment with the candidate is concluded by the person responsible for processing, the application documents will be automatically deleted six months after the rejection decision has been announced, provided that the deletion does not conflict with any other legitimate interests of the person responsible for processing. Other legitimate interest in this sense is, for example, a burden of proof in a procedure under the General Equal Treatment Act (Allgemeines Gleichbehandlungsgesetz = AGG).
We expressly point out that, due to central functions within the framework in the application process, we may have to pass on your application documents to the following member companies of our group:InfraServ GmbH & Co. Wiesbaden KG, Germany

The person responsible for processing has integrated Twitter components on their website. Twitter is a multilingual, publicly available microblogging service, where users can post and distribute so-called tweets, i.e. short messages which are limited to 280 characters. These short messages are available to anyone, including non-Twitter subscribers. The tweets are, however, also displayed to the so-called followers of the respective user. Followers are other Twitter users who follow a user's tweets. Additionally, Twitter allows you to address a broad audience via hashtags, links, or retweets.
The operating company of Twitter is Twitter, Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, USA.
Each time one of the individual pages of this website, which is operated by the person responsible for processing and on which a Twitter component (Twitter button) has been integrated, is accessed, the Internet browser on the information technology system of the person concerned is automatically activated by the respective Twitter component and causes a download of a display of the corresponding Twitter component from Twitter. Further information on the Twitter buttons is available at about.twitter.com/en/resources/buttons. As part of this technical process, Twitter receives information on the specific sub-page of our website that is being visited by the person concerned. The purpose of the integration of the Twitter component is to allow our users to redistribute the contents of this website, to promote this website in the digital world and to increase our visitor numbers. If the person concerned is simultaneously logged in on Twitter, Twitter recognizes which specific sub-page of our website the person concerned is visiting with each visit to our website and during the entire duration of the respective stay on our website. This information is collected through the Twitter component and assigned through Twitter to the Twitter account of the person concerned. If the person concerned activates one of the Twitter buttons integrated on our website, the data and information transmitted with it are assigned to the personal Twitter user account of the person concerned and stored and processed by Twitter. Twitter always receives information via the Twitter component that the person concerned has visited our website if the person concerned is simultaneously logged in on Twitter at the time of the access to our website; this happens regardless of whether or not the person concerned clicks on the Twitter component. If such a transmission of this information to Twitter is not wanted by the person concerned, they can prevent the transmission by logging out of their Twitter account before accessing our website. The current privacy policies of Twitter are available at https://twitter.com/privacy?lang=en
The person responsible for processing has integrated YouTube components on their website. YouTube is an internet video portal that allows video publishers to place video clips for free, and it allows other users to view, evaluate and comment such videos. YouTube allows the publication of all types of videos, so that both complete film and television broadcasts, but also music videos, trailers or user-made videos are available via the Internet portal.
YouTube's operating company is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. YouTube, LLC is a subsidiary of Google Inc., 1600 Amphitheater Pkwy, Mountain View, CA 94043-1351, USA.
This site uses the mapping service Google Maps via an API. Provider is Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA.
It is necessary to store your IP address in order to use the features of Google Maps. This information is usually transmitted to and stored on a Google server in the United States. The provider of this site has no influence on this data transmission.
The use of Google Maps takes place in the interest of an attractive display of our online offers and an easy findability of the places we have indicated on the website. This constitutes a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR.
This site uses so-called web fonts, provided by Google, for the standardized display of fonts. When you access a page, your browser loads the required web fonts into your browser cache to display texts and fonts correctly.
To do this, the browser you use has to connect to Google's servers. As a result, Google learns that our website has been accessed via your IP address.
The use of Google Web Fonts takes place in the interest of a standardized and attractive display of our online offers. This constitutes a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR. If your browser does not support web fonts, a default font will be used by your computer.
This site uses the service of the company eTermin GmbH for bookings of online appointments. Personal data are collected and processed only to the extent necessary in the context of this booking of online appointments. Only the information referring to data marked with an asterisk is obligatory; this information is indispensable for the use of the service (Art. 6 para. 1 s. 1 lit. b GDPR). The statement of further data may be helpful but is not mandatory (voluntary information, Art. 6 para. 1 s. 1 lit. a GDPR). We process and store your personal data, as long as it is necessary for the fulfilment of our contractual and legal obligations. If the storage of personal data for the fulfilment of these obligations is no longer required, they will be deleted, unless there are statutory storage requirements.
When you use our own app, no personal information (such as IP addresses, name of the end device, transaction data) is collected. Access to local data (e.g. contact details, files) other than image data is not carried out. If access to locally stored images or the built-in camera is desired or necessary, the access will be conducted by the user himself or his consent is obtained before the access. If it becomes necessary to store data within the scope of the use of the app on an end device, these data are always being encrypted.
By applying for the inclusion in the electronic telephone book in the KANET, you agree that the data you provide for the purpose of publication in a public telephone directory (for the participants in the Industrial Park Kalle-Albert) are recorded, transmitted and processed. InfraServ Wiesbaden does not pass on those data to third parties beyond that.
Art. 6 I lit. a GDPR serves our company as the legal basis for processing operations, where we obtain consent for a particular processing purpose. If the processing of personal data is necessary to fulfill a contract of which the person concerned is a contracting party, as is the case, for example, in the case of processing operations for a delivery of goods or the provision of any other service or service in return, the processing is based on Art. 6 I lit. b GDPR. The same applies to such processing operations that are necessary to carry out pre-contractual measures, for example in cases of inquiries regarding our products or services. If our company is subject to a legal obligation by which a processing of personal data is required, such as for the fulfillment of tax obligations, the processing is based on Art. 6 I lit. c GDPR. In rare cases, the processing of personal data may be required to protect the vitally important interests of the person concerned or another natural person. This would be the case, for example, if a visitor to our premises were injured and their name, age, health insurance data, or other vitally important information would have to be passed on to a doctor, hospital or other third party. Then the processing would be based on Art. 6 I lit. d GDPR. In the end, processing operations could be based on Art. 6 I lit. f GDPR. Processing operations, which are not covered by any of the above-mentioned legal foundations, are based on this legal foundation if the processing is necessary to safeguard the legitimate interests of our company or a third party, provided the interests, fundamental rights and fundamental freedoms of the person concerned do not prevail. Such processing operations are allowed to us in particular, because they have been especially mentioned by the European issuer of directives and regulations. In that regard, the European issuer of directives and regulations considered that a legitimate interest could be assumed if the person concerned is a customer of the person responsible for processing (Recital 47, para. 2, GDPR).
If the processing of personal data is based on Article 6 I lit. f GDPR, our legitimate interest is in conducting our business activities for the welfare of all of our employees and our shareholders.
The criterion for the duration of the storage of personal data is the respective statutory retention period. After the end of the period, the corresponding data will be routinely deleted if they are no longer required to fulfill the contract or to initiate a contract.
21. Legal or contractual regulations for the provision of personal data; necessity for the conclusion of the contract; obligation of the person concerned to provide the personal data; possible consequences of non-provision
We clarify that the provision of personal information is in part required by law (such as tax regulations) or may result from contractual arrangements (such as details of the contractual party). Occasionally, it may be necessary for a contract to be concluded that a person concerned provides us with personal data that must subsequently be processed by us. For example, the person concerned is required to provide us with personal data when our company closes a contract with them. Failure to provide the personal data would result in the non-closure of the contract with the person concerned. Prior to any personal data being provided by the person concerned, the person concerned must contact one of our employees. Our employee will inform the person concerned on a case-by-case basis, whether the provision of the personal data is required by law or by contract or for the conclusion of the contract, whether there is any obligation to provide the personal data and which consequence failure to provide them would have.
