Privacy Policy


We, L-One Systems GmbH (hereinafter: "the company", "we" or "us") take the protection of your personal data seriously and would like to inform you at this point about data protection in our company.  

Within the scope of our responsibility under data protection law, additional obligations have been imposed on us by the entry into force of the EU General Data Protection Regulation (Regulation (EU) 2016/679; hereinafter: "DS-GVO") in order to ensure the protection of personal data of the person affected by a processing operation (we also address you as a data subject hereinafter with "customer", "user", "you", "you" or "data subject").  

Insofar as we decide either alone or jointly with others on the purposes and means of data processing, this includes above all the obligation to inform you transparently about the nature, scope, purpose, duration and legal basis of the processing (cf. Articles 13 and 14 DS-GVO). With this statement (hereinafter: "Privacy Notice"), we inform you about the manner in which your personal data is processed by us.  

Our data protection notices have a modular structure. They consist of a general part for any processing of personal data and processing situations that come into play each time a website is called up (A. General) and a special part, the content of which relates in each case only to the processing situation specified there with the designation of the respective offer or product, in particular the visit to websites as detailed here (B. Visit to websites).  

In order to be able to find the parts relevant to you, please note the following overview of the subdivision of the data protection information:  

Part A is called General and is always relevant for you. 

Part B is called Website and social media presences and it is relevant for you if you use our German website including social media presences.


 A. General  

(1) Definitions  

Following the model of Art. 4 DS-GVO, this data protection notice is based on the following definitions:  

  • "Personal data" ( Art. 4 No. 1 DS-GVO) means any information relating to an identified or identifiable natural person ("data subject"). A person is identifiable if he or she can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, an online identifier, location data or by means of information relating to his or her physical, physiological, genetic, mental, economic, cultural or social identity characteristics. The identifiability can also be given by means of a linkage of such information or other additional knowledge. The origin, form or embodiment of the information does not matter (photographs, video or sound recordings may also contain personal data).  
  • "Processing" ( Art. 4 No. 2 GDPR) means any operation which involves the handling of personal data, whether or not by automated (i.e. technology-based) means. This includes, in particular, the collection (i.e. acquisition), recording, organization, arrangement, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment, combination, restriction, erasure or destruction of personal data, as well as the change of an objective or purpose on which a data processing was originally based.  
  • "Controller" ( Art. 4 No. 7 DS-GVO) means the natural or legal person, public authority, agency or other body which alone or jointly with others determines the purposes and means of the processing of personal data.  
  • "Third Party" ( Art. 4 No. 10 DS-GVO) means any natural or legal person, public authority, agency or other body other than the Data Subject, the Controller, the Processor and the persons who, under the direct responsibility of the Controller or Processor, are authorized to process the Personal Data; this also includes other group-affiliated legal entities.  
  •  "Processor" ( Art. 4 No. 8 DS-GVO) is a natural or legal person, authority, institution or other body that processes personal data on behalf of the controller, in particular in accordance with the controller's instructions (e.g. IT service provider). In terms of data protection law, a processor is in particular not a third party.  
  •  "Consent" ( Art. 4 No. 11 DS-GVO) of the data subject means any expression of will given voluntarily for the specific case, in an informed manner and unambiguously in the form of a statement or other unambiguous confirmatory act by which the data subject indicates that he or she consents to the processing of personal data relating to him or her.

(4) Legal basis for data processing  

By law, any processing of personal data is in principle prohibited and only permitted if the data processing falls under one of the following justifications:  


  • Art. 6 (1) p. 1 lit. a DS-GVO ("consent"): If the data subject has voluntarily, in an informed manner and unambiguously indicated by a statement or other unambiguous confirmatory act that he or she consents to the processing of personal data relating to him or her for one or more specific purposes;  
  • Art. 6 (1) p. 1 lit. b DS-GVO: If the processing is necessary for the performance of a contract to which the data subject is a party or for the performance of pre-contractual measures taken at the data subject's request;  
  • Art. 6 (1) p. 1 lit. c DS-GVO: If the processing is necessary for compliance with a legal obligation to which the controller is subject (e.g., a legal obligation to keep records);  
  • Art. 6 para. 1 p. 1 lit. d DS-GVO: If the processing is necessary to protect vital interests of the data subject or another natural person;  
  • Art. 6 (1) p. 1 lit. e DS-GVO: If the processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller; or  
  • Art. 6 (1) p. 1 lit. f DS-GVO ("Legitimate Interests"): If the processing is necessary to protect legitimate (in particular legal or economic) interests of the controller or a third party, unless the conflicting interests or rights of the data subject override (in particular if the data subject is a minor).    

Storing information in the end user's terminal equipment or accessing information already stored in the terminal equipment is only permitted if it is covered by one of the following justifications:  

  • Section 25 (1) TTDSG: If the end user has consented on the basis of clear and comprehensive information. The consent has to be given according to Art. 6 para. 1 p. 1 lit. a DS-GVO;  
  • Section 25 (2) no. 1 TTDSG: If the sole purpose is to carry out the transmission of a message via a public telecommunications network; or  
  • Section 25 (2) no. 2 TTDSG: If the storage or access is absolutely necessary for the provider of a telemedia service to provide a telemedia service expressly requested by the user.  

For the processing operations carried out by us, we indicate below the applicable legal basis in each case. A processing operation may also be based on several legal bases.  


(5) Data deletion and storage period  

For the processing operations carried out by us, we indicate below in each case how long the data will be stored by us and when it will be deleted or blocked. If no explicit storage period is specified below, your personal data will be deleted or blocked as soon as the purpose or legal basis for the storage no longer applies. In principle, your data will only be stored on our servers in Germany, subject to any transfer that may take place in accordance with the regulations in A.(7) and A.(8).  

However, storage may take place beyond the specified time in the event of a (threatened) legal dispute with you or other legal proceedings, or if storage is required by legal regulations to which we are subject as the responsible party (e.g. § 257 HGB, § 147 AO). If the storage period prescribed by the legal regulations expires, the personal data will be blocked or deleted unless further storage by us is necessary and there is a legal basis for this.  



(6) Data security  


We use appropriate technical and organizational security measures to protect your data against accidental or intentional manipulation, partial or complete loss, destruction or against unauthorized access by third parties (e.g. TSL encryption for our website), taking into account the state of the art, implementation costs and the nature, scope, context and purpose of the processing, as well as the existing risks of a data breach (including its probability and impact) for the data subject. Our security measures are continuously improved in line with technological developments.  

We will be happy to provide you with more detailed information on request. Please contact our data protection officer (see under A.(3)). 


(7) Cooperation with Processors  

As with any larger company, we also use external domestic and foreign service providers (e.g. for IT, logistics, telecommunications, sales and marketing) to process our business transactions. These service providers only act on our instructions and are contractually obligated to comply with the provisions of data protection law in accordance with Art. 28 DS-GVO.  

If personal data from you is passed on by us to our subsidiaries or is passed on to us by our subsidiaries (e.g. for advertising purposes), this is done on the basis of existing order processing relationships.  


(8) Conditions for the transfer of personal data to third countries  

In the course of our business relationships, your personal data may be passed on or disclosed to third party companies. These may also be located outside the European Economic Area (EEA), i.e. in third countries. Such processing takes place exclusively for the fulfillment of contractual and business obligations and for the maintenance of your business relationship with us (legal basis is Art. 6 para. 1 lit b or lit f in each case in conjunction with Art. 44 et seq. DS-GVO). We will inform you about the respective details of the transfer in the relevant places below.  

The European Commission certifies data protection comparable to the EEA standard in some third countries by means of so-called adequacy decisions (a list of these countries and a copy of the adequacy decisions can be obtained here: https://ec.europa.eu/info/law/law-topic/data-protection/international-dimension-data-protection/adequacy-decisions_en). However, in other third countries to which personal data may be transferred, there may not be a consistently high level of data protection due to a lack of legal provisions. If this is the case, we ensure that data protection is adequately guaranteed. This is possible via binding company regulations, standard contractual clauses of the European Commission for the protection of personal data pursuant to Art. 46 para. 1 , 2 lit. c DS-GVO (the standard contractual clauses of 2021 are available at https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32021D0915&locale-en), certificates or recognized codes of conduct. Please contact our data protection officer (see under A.(3)) if you would like to receive more information on this.  


(9) No automated decision making (including profiling) 

We do not intend to use any personal data collected from you for any automated decision-making process (including profiling).  


(10) No obligation to provide personal data  

We do not make the conclusion of contracts with us dependent on you providing us with personal data in advance. For you as a customer, there is also basically no legal or contractual obligation to provide us with your personal data; however, it may be that we can only provide certain offers to a limited extent or not at all if you do not provide the data required for this. If this should exceptionally be the case in the context of the products we offer presented below, you will be informed of this separately.  


(11) Legal obligation to transfer certain data  

We may, under certain circumstances, be subject to a specific legal or statutory obligation to provide the lawfully processed personal data to third parties, in particular public bodies ( Art. 6 para. 1 p. 1 lit. c DS-GVO). 


(12) Your rights  

You may assert your rights as a data subject regarding your processed personal data at any time by contacting us using the contact details provided at the beginning of A.(2). As a data subject, you have the right  

  • to request information about your data processed by us in accordance with Art. 15 DS-GVO. In particular, you can request information about the processing purposes, the category of data, the categories of recipients to whom your data has been or will be disclosed, the planned storage period, the existence of a right to rectification, erasure, restriction of processing or objection, the existence of a right of complaint, the origin of your data if it has not been collected by us, as well as the existence of automated decision-making, including profiling, and, if applicable, meaningful information about its details;  
  • in accordance with Art. 16 DS-GVO, to demand the correction of incorrect data or the completion of your data stored by us without delay;  
  • pursuant to Art. 17 DS-GVO, to request the deletion of your data stored by us, unless the processing is necessary for the exercise of the right to freedom of expression and information, for compliance with a legal obligation, for reasons of public interest or for the assertion, exercise or defense of legal claims;  
  • pursuant to Art. 18 DS-GVO, to request the restriction of the processing of your data, insofar as the accuracy of the data is disputed by you or the processing is unlawful;  
  • pursuant to Art. 20 DS-GVO, to receive your data that you have provided to us in a structured, common and machine-readable format or to request the transfer to another controller ("data portability");  
  • object to the processing in accordance with Art. 21 DS-GVO, provided that the processing is based on Art. 6 (1) p. 1 lit. e or lit. f DS-GVO. This is particularly the case if the processing is not necessary for the performance of a contract with you. Unless it is an objection to direct marketing, when exercising such an objection, we ask you to explain the reasons why we should not process your data as we have done. In the event of your justified objection, we will review the merits of the case and either discontinue or adjust the data processing or show you our compelling legitimate grounds on the basis of which we will continue the processing;  
  • in accordance with Article 7 (3) of the GDPR, to revoke your consent given once (also before the GDPR came into force, i.e. before 25.5.2018) - i.e. your voluntary will, made understandable in an informed manner and unambiguously by means of a declaration or other unambiguous confirming act, that you agree to the processing of the personal data in question for one or more specific purposes - at any time vis-à-vis us, if you have given such consent. This has the consequence that we may no longer continue the data processing, which was based on this consent, for the future and  
  • to complain to a data protection supervisory authority about the processing of your personal data in our company in accordance with Art. 77 DS-GVO, such as the data protection supervisory authority responsible for us: The Hessian Commissioner for Data Protection and Freedom of Information, P.O. Box 3163, 65021 Wiesbaden, e-mail: poststelle@datenschutz.hessen.de   


(13) Changes to data protection information  

In the context of the further development of data protection law as well as technological or organizational changes, our data protection information is regularly reviewed to determine whether it needs to be adapted or supplemented. You will be informed of any changes, in particular on our German website at www.l-one.de. This data protection notice is current as of November 2022. 


B. Visiting web pages  


(1) Explanation of function  

You can obtain information about our company and the services we offer in particular at www.l-one.de together with the associated sub-pages (hereinafter collectively referred to as "websites"). When you visit our Web pages, personal data may be processed.  


 (2) Processed personal data  

During the informational use of the Websites, the following categories of personal data are collected, stored and processed by us:  


"log data": When you visit our websites, a so-called protocol data record (so-called server log files) is stored temporarily and anonymously on our web server. This consists of:  

  • the page from which the page was requested (so-called referrer URL)  
  • the name and URL of the requested page  
  • the date and time of the request  
  • the description of the type, language and version of the web browser used  
  • the IP address of the requesting computer, which is shortened in such a way that a personal reference can no longer be established  
  • the amount of data transferred  
  • the operating system  
  • the message whether the request was successful (access status/http status code)  
  • the GMT time zone difference  


"contact form data": When contact forms are used, the data transmitted as a result are processed (e.g. gender, surname and first name, address, company, e-mail address and the time of transmission).  


In addition to the purely informational use of our website, we offer the subscription to our newsletter, with which we inform you about current topics in software development, news about L-One Systems, events and more. If you subscribe to our newsletter, the following "newsletter data" will be collected, stored and processed by us:  


  • the page from which the page was requested (so-called referrer URL)  
  • the form type  
  • the date and time of the request  
  • the description of the type of web browser used  
  • the IP address of the requesting computer, which is shortened in such a way that a personal reference can no longer be established  
  • the approximate location of the requesting computer  
  • the e-mail address  
  • the first and last name, if these are given in the form  
  • the gender, if this is indicated in the form  
  • the date and time of registration, of opening the confirmation e-mail and of clicking the confirmation link.  

We would like to point out that we evaluate your user behavior when sending the newsletter. For this evaluation, the emails sent contain so-called web beacons or tracking pixels, which are single-pixel image files stored on our website. For the evaluations, we link the aforementioned data and the web beacons with your e-mail address and an individual ID. Links contained in the newsletter also contain this ID. The data is collected exclusively pseudonymously, i.e. the IDs are not linked to your other personal data, and direct personal reference is excluded. 


(3) Purpose and legal basis of data processing  

We process the personal data described in more detail above in accordance with the provisions of the DS-GVO, the other relevant data protection regulations and only to the extent necessary. Insofar as the processing of personal data is based on Art. 6 (1) p. 1 lit. f DS-GVO, the aforementioned purposes also represent our legitimate interests.  


The processing of log data serves statistical purposes and to improve the quality of our website, in particular the stability and security of the connection (legal basis is Art. 6 para. 1 p. 1 lit. a or lit. f DS-GVO).  


Contact form data is processed for the purpose of handling customer inquiries (legal basis is Art. 6 para. 1 p. 1 lit. b or lit. f DS-GVO).  


Newsletter data is processed for the purpose of sending the newsletter. In the course of registering for our newsletter, you consent to the processing of your personal data (legal basis is Art. 6 para. 1 lit. a DS-GVO). For the registration to our newsletter, we use the so-called double opt-in procedure. This means that after your registration, we will send you an e-mail to the e-mail address you provided, in which we ask you to confirm that you wish to receive the newsletter. The purpose of this procedure is to be able to prove your registration and, if necessary, to clarify a possible misuse of your personal data. You can revoke your consent to the sending of the newsletter at any time and unsubscribe from the newsletter. You can declare the revocation by clicking on the link provided in each newsletter e-mail, by e-mail to marketing@l-one.de or by sending a message to the contact details provided in the imprint.  


If the processing of the data requires the storage of information in your terminal equipment or access to information already stored in the terminal equipment, Section 25 (1), (2) TTDSG is the legal basis for this.  

(4) Duration of data processing  

Your data will only be processed for as long as is necessary to achieve the above-mentioned processing purposes; the legal bases specified in the context of the processing purposes apply accordingly. With regard to the use of cookies, please refer to point A.(5).  

Third parties used by us will store your data on their system for as long as it is necessary in connection with the provision of services for us in accordance with the respective order.  


(5) Transfer of personal data to third parties; basis for justification  

The following categories of recipients, which are usually order processors (see A.(7)), may receive access to your personal data:  


  • Service providers for the operation of our website and the processing of data stored or transmitted by the systems (e.g. for data center services, payment processing, IT security). The legal basis for the transfer is then Art. 6 para. 1 p. 1 lit. b or lit. f DS-GVO, insofar as these are not order processors;  
  • Government agencies/authorities, insofar as this is necessary for the fulfillment of a legal obligation. The legal basis for the transfer is then Art. 6 para. 1 p. 1 lit. c DS-GVO;  
  • Persons employed to carry out our business operations (e.g. auditors, banks, insurance companies, legal advisors, supervisory authorities, parties involved in company acquisitions or the establishment of joint ventures). The legal basis for the disclosure is then Art. 6 para. 1 sentence 1 lit. b or lit. f DS-GVO.  


For the guarantees of an adequate level of data protection in the event of a transfer of data to third countries, see A.(8).   

In addition, we will only share your personal data with third parties if you have given your express consent to do so in accordance with Art. 6 para. 1 p. 1 lit. a DS-GVO.

c) Plugins and tools  

YouTube with enhanced data protection  

This website embeds videos from YouTube. The operator of the pages is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.  

As soon as you start a YouTube video on this website, a connection to YouTube's servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, you enable YouTube to assign your surfing behavior directly to your personal profile. You can prevent this by logging out of your YouTube account.   

Furthermore, YouTube can save various cookies on your end device after starting a video or use comparable recognition technologies (e.g. device fingerprinting). In this way, YouTube can obtain information about visitors to this website. This information is used, among other things, to collect video statistics, improve the user experience, and prevent fraud attempts.  

If necessary, further data processing operations may be triggered after the start of a YouTube video, over which we have no control.  

YouTube is used in the interest of an appealing presentation of our online offers. This represents a legitimate interest within the meaning of Art. 6 para. 1 lit. f DSGVO. Insofar as a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG, insofar as the consent includes the storage of cookies or access to information in the user's terminal device (e.g. device fingerprinting) within the meaning of the TTDSG. The consent can be revoked at any time.

Once consent has been given, it will be read automatically for up to 12 months on subsequent visits and followed accordingly.  

You can find out more about data protection at Cookiebot here: https://www.cookiebot.com/de/privacy-policy/   


Google Plugins  

Google Ads  

We use the ad services of Google Ads as well as Google Ads Remarketing to reach users with our offer. Google Ads is an online advertising program of Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.  

Google Ads enables us to play advertisements in the Google search engine or on third-party websites when the user enters certain search terms on Google (keyword targeting). Furthermore, targeted advertisements can be played on the basis of user data available at Google (e.g. location data and interests) (target group targeting). As the website operator, we can evaluate this data quantitatively by analyzing, for example, which search terms have led to the display of our advertisements and how many ads have resulted in corresponding clicks.  

The use of Google Ads results in the user's IP address being stored. Furthermore, user interactions are tracked and stored to provide the website operator with information about how users arrived at the website.  

The use of Google Ads is based on Art. 6 para. 1 lit. f DSGVO. The website operator has a legitimate interest in marketing its service products as effectively as possible.  

The data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found here: https://policies.google.com/privacy/frameworks and https://privacy.google.com/businesses/controllerterms/mccs/.  

You can read all details on data protection regarding Google Ads here: https://ads.google.com/intl/de_de/home/faq/gdpr/ 


Google Tag Manager  

For our online presence, we use the Google Tag Manager with which we operate website tags within the framework of an interface management, in order to be able to use e.g. marketing/tracking services from Google or other third-party providers in our website.   

The Google Tag Manager itself does not process any personal data. Regarding the processing of personal data, please refer to the more detailed information on the respective marketing/tracking tools in this privacy policy.  


Google Analytics 4 (GA4) 

If you have given your consent, Google Analytics 4 (GA4) is used on this website, hereinafter referred to as "Google Analytics". It is a web analytics service provided by Google LLC. The responsible entity for users in the EU / EEA and Switzerland is Google Ireland Limited, Google Building Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland ("Google").  

Google Analytics uses cookies that enable an analysis of your use of our websites. The information collected by means of the cookies about your use of this website is generally transferred to a Google server in the USA and stored there.  

We use the User ID function. With the help of the User ID, we can assign a unique, permanent ID to one or more sessions (and the activities within these sessions) and analyze user behavior across devices.  

We use Google Signals. This allows Google Analytics to collect additional information about users who have enabled personalized ads (interests and demographics), and ads can be delivered to these users in cross-device remarketing campaigns.

The website operator uses the Mailchimp marketing platform to collect data from prospective customers and customers in a data-protection-compliant manner via "double opt-in" (which stands for twofold consent). In addition, the tool is used to send newsletters. For these purposes, information from prospects and customers that has been collected via the website is also stored at Mailchimp.  

Data is only collected when it is actively sent by users to the website operator via one of the forms available on the website. The data collection can be done through these three ways:  

  • Via the contact form  
  • Via the form to register for our newsletter  
  • Via the form for downloading premium resources  

In addition to the data users enter directly in the forms, we also collect the form type, the date and time the form was submitted, the opening of the confirmation email, as well as the date and time the confirmation link in the email was clicked, and the approximate location of the user. This data is stored in Mailchimp.  

The documentation of this data serves the purpose of being able to prove the double opt-in if necessary.  

More information on the handling of user data can be found in Mailchimp's privacy policy: https://www.intuit.com/privacy/statement/.  



The website operator uses the customer relationship management system (CRM) Pipedrive to store and manage information from interested parties and customers and to use it for the purpose of contacting them or sending newsletters. In Pipedrive, we also process data that has been collected via the website.  

Data is only collected if it is actively sent by users to the website operator via one of the existing forms. The data collection can be done through these three ways:  

  • Via the contact form  
  • Via the form to register for our newsletter  
  • Via the form for downloading premium resources.  

In addition to the data that users provide directly in the forms, we also forward information about the type of form and the date on which the confirmation link in the confirmation email was clicked to our CRM.  

In the case of the contact form, this serves the purpose of making the inquiries available internally to the correct contact person as quickly as possible, processing them and quickly establishing contact with the interested parties. Any subsequent communication of the prospects or customers with our account managers is also stored in Pipedrive.  

In the case of the form for registering for our newsletter, as well as the form for downloading premium resources, the purpose of the data processing is to manage the distribution list of our newsletter.

Use of Calendly

For online appointments, we use the tool Calendly. We redirect website users to a Calendly appointment booking page when they click on a corresponding link (e.g., "Make an appointment" or "Book an initial consultation").  

In order to book an appointment, you must provide us with your full name, email address and company name via the form. This is so that we can send you an appointment invitation. In addition, this information helps us to prepare for the appointment with you in advance so that we can make the best use of your time. Information about your telephone number and your request is voluntary.  

Data processing for the purpose of making an appointment is based on your voluntarily given consent in accordance with Art. 6 para. 1 p. 1 lit. a DSGVO. For the processing of your personal data, the conditions apply, which you can find in section B (2) in this privacy policy. 

You can find more information on the handling of user data in Calendly's privacy policy: https://calendly.com/en/privacy


d) Social media plugins  

We currently use the following social media plug-ins: Xing, LinkedIn, Facebook, which are only loaded if you have previously activated the function by giving your consent. Through the plug-ins, we offer you the opportunity to interact with the social networks and other users. The legal basis for the use of the plug-ins is Art. 6 para. 1 p. 1 lit. a DS-GVO, i.e. the integration only takes place after your consent.  

The plug-in provider stores the data collected about you as usage profiles and uses them for purposes of advertising, market research and/or demand-oriented design of its website. Such an evaluation is carried out in particular (also for users who are not logged in) for the display of needs-based advertising and to inform other users of the social network about your activities on our website. You have the right to object to the creation of these user profiles, whereby you must contact the respective plug-in provider to exercise this right. The data transfer takes place regardless of whether you have an account with the plug-in provider and are logged in there. If you are logged in to the plug-in provider, your data collected from us will be directly assigned to your account with the plug-in provider. If you click the activated button and, for example, link to the page, the plug-in provider also saves this information in your user account and shares it publicly with your contacts. We recommend that you log out regularly after using a social network, but especially before activating the button, as this allows you to avoid an assignment to your profile with the plug-in provider. 

The information collected is stored on servers of the providers, in the case of international providers also outside Europe. For these cases, the provider has, according to its own information, imposed a standard on itself that corresponds to the former EU-US Privacy Shield and has promised to comply with applicable data protection laws in the international transfer of data.   

The revocation of your consent is possible at any time without affecting the permissibility of the processing until the revocation. The easiest way to revoke is via our Consent Manager or via the functions of the social media providers.  

For more information on the purpose and scope of data collection and its processing by the plug-in provider, please refer to the data protection declarations of these providers communicated below. There you will also receive further information on your rights in this regard and setting options for protecting your privacy.
