Personal data

Personal data within the meaning of the General Data Protection Regulation (GDPR) is any information relating to an identified or identifiable natural person, for example, your civil name, address, telephone number and date of birth.

The processing of personal data can be based on various legal bases. If we need your data to fulfill a contract with you or to respond to inquiries from you regarding a contract, the legal basis for this data processing is Art. 6 para. 1 p. 1 lit. b GDPR. If we obtain your consent for certain data processing, the legal basis is Art. 6 para. 1. p. 1 lit. a GDPR. We carry out some data processing on the basis of our legitimate interest, always weighing your interests worthy of protection against our legitimate interests. The legal basis here is Art. 6 para. p. 1 lit. f GDPR. Insofar as processing is necessary to fulfill a legal obligation to which we are subject, the legal basis is Art. 6 para. 1 p. 1 lit. c GDPR.


Collection of personal data when visiting our website

In the case of merely informational use of the website, i.e. if you do not transmit information to us in any other way, we only collect the personal data that your browser transmits to our server. If you wish to view our website, we collect the following data, which is technically necessary for us to display our website to you and to ensure its stability and security: IP address, date and time of the request, time zone difference to Greenwich Mean Time (GMT), content of the request (specific page), access status/HTTP status code, amount of data transferred in each case, website from which the request comes, browser, operating system, and its interface, language and version of the browser software.

The last four digits of the IP address are replaced by a zero and are therefore no longer clearly traceable to the source.

We regularly do not know who is behind an IP address. We do not combine the data listed above with other data.

The legal basis is Art. 6 para. 1 p. 1 lit. f GDPR. Since the collection of data for the provision of the website and the storage in log files are absolutely necessary for the operation of the website and to protect against misuse, our legitimate interest in data processing prevails at this point.



You can apply to our company electronically, e.g. via e-mail or web forms. Please note that unencrypted e-mails will not be transmitted with access protection.

Your details will be used for processing your application and deciding whether to establish an employment relationship. The legal basis is § 26 para. 1 in conjunction with. Abs. 8 S.2 BDSG. Furthermore, your personal data may be processed insofar as this should be necessary for the defense of asserted legal claims against us arising from the application process. The legal basis for this is Art. 6 para. 1 p.1 lit. f GDPR. The stated purposes also constitute the legitimate interest in the processing.

We would be happy to forward your application within the group of companies should you be rejected. Forwarding will only take place if you consent to it. The legal basis is Art. 6 para. 1 p. 1 lit. a GDPR. Your consent is voluntary, you can revoke it at any time with effect for the future.

If an employment relationship is established between you and us, we may process the personal data already received from you for the purposes of the employment relationship in accordance with section 26 (1) of the BDSG if this is necessary for the implementation or termination of the employment relationship or for the exercise or fulfilment of the rights and obligations of the employee representation resulting from a law or a collective agreement, a works agreement or a service agreement (collective agreement).

Your application data will not be processed beyond the described use.

Your personal data will be deleted after completion of the application procedure after 6 months at the latest, provided that no other legitimate interests on our part oppose deletion or you have not given us consent for longer storage. Other legitimate interests in this sense include, for example, a duty to provide evidence in proceedings under the General Equal Treatment Act (AGG).


Data collection and processing contact form

When you contact us by e-mail or via a contact form, the data you provide (your e-mail address, name and telephone number, if applicable) will be stored by us in order to answer your questions and process your requests. The legal basis in this respect is Art. 6 para. 1 p. 1 lit. f GDPR.

Insofar as we request information via our contact form that is not necessary for contacting you, we have always marked this as optional. We use this information to specify your request and to improve the processing of your request. Any communication of this information is expressly on a voluntary basis and with your consent, Art. 6 para. 1 p. 1 lit. a GDPR. Insofar as this involves information on communication channels (e.g. e-mail address, telephone number), you also consent to us contacting you via this communication channel, if necessary, in order to respond to your request. You can, of course, revoke this consent at any time for the future.

Your data that we have received in the course of contacting you will be deleted as soon as it is no longer required to achieve the purpose for which it was collected, your request has been fully processed and no further communication with you is necessary or desired by you.

As the controller, our company has implemented numerous technical and organisational measures to ensure the most complete protection of personal data processed through this website. Nevertheless, internet-based data transmissions can always have security gaps. Absolute protection cannot be guaranteed; in any case, sending unencrypted e-mails is not secure. We therefore ask you not to send sensitive data by unencrypted e-mail, but to use either encrypted communication channels (e.g. our contact form) or the postal service.


Cookies and analysis services

Our website uses cookies. Cookies are data that are stored on your computer by a website you visit and enable your browser to be reassigned. Cookies transmit information to the entity that sets the cookie. Cookies can store various information, such as your language setting, the duration of your visit to our website or the entries you have made there. This prevents you, for example, from having to re-enter required form data each time you use the site. The information stored in cookies can also be used to recognise preferences and to target content according to areas of interest.

There are different types of cookies:

Session cookies are sets of data that are only temporarily held in memory and deleted when you close your browser.

Permanent or persistent cookies are automatically deleted after a set period of time, which may vary depending on the cookie. With this type of cookie, the information can also be stored in text files on your computer. However, you can also delete these cookies at any time via your browser settings.

First-party cookies are set by the website you are currently visiting. Only this website is allowed to read information from these cookies.

Third-party cookies are set by organisations that do not operate the website you are visiting. These cookies are used by marketing companies, for example.

The legal basis for possible processing of personal data by means of cookies and their storage period may vary. If you have given us your consent, the legal basis is Art. 6 (1) sentence 1 lit. a GDPR. Insofar as the data processing is based on our overriding legitimate interests, the legal basis is Art. 6 para. 1 p. 1 lit. f GDPR. The stated purpose then corresponds to our legitimate interest.

We use cookies to ensure the proper operation of the website, to provide basic functionalities, for range measurement and – with your consent – to tailor our services to preferred areas of interest.

You can delete cookies already stored on your terminal device at any time. If you wish to prevent cookies from being stored, you can do so via the settings in your internet browser. Alternatively, you can also install so-called ad blockers. Please note that individual functions of our website may not work if you have deactivated the use of cookies.

When accessing our website, all users of our website are also informed by an information banner about our use of cookies and referred to this data protection notice. As a user, you will also be asked for your consent to the use of certain cookies, particularly those relevant to the personalisation of services and for marketing measures. Once you have given your consent, you can revoke it at any time with future effect by clicking on the “Cookie settings” button at the bottom of our website and unchecking the box next to the processing to which you have consented.

This website uses the following types of cookies, the scope and functionality of which are explained below:

a. Technically necessary cookies:

Technically necessary cookies that are required to carry out the electronic communication process or to provide certain functions you have requested are stored on the basis of Art. 6 para. 1 p. 1 lit f GDPR. The website operator has a legitimate interest in storing cookies for the technically error-free and optimised provision of its services. Technically necessary cookies on this website are:


To obtain consent for cookie use via our website, we use the service Borlabs, a software of Borlabs – Benjamin A. Bornschein, Rübenkamp 32, 22305 Hamburg.

Borlabs checks whether a user has already consented to the use of cookies via the consent tool during a previous visit to our website. For this purpose, a cookie is set and a log file is created as proof of consent. The following information is stored in the “borlabs-cookie” cookie:

  • Cookie runtime
  • Cookie version
  • Domain and path of the WordPress website
  • Consents
  • UID

The UID is a randomly generated ID and is not personal information.

The purpose of the data processing is to comply with legal obligations and to store the consent. The legal basis is Art. 6 para. 1 p. 1 lit. f GDPR. Our legitimate interest lies in the compliance with legal requirements and the storage of consent. The storage period of the information listed above is based on the storage period of the cookie – if this is deleted, the information listed above is also deleted.

b. Technically unnecessary cookies

There are also cookies that primarily serve marketing purposes. These include Google Analytics. These cookies are dealt with in the following sections.

aa. Google Analytics

So far as you have given your consent, Google Analytics, a web analytics service provided by Google LLC, is used on this website. 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”).


Scope of processing

Google Analytics uses cookies that enable an analysis of your use of our website. 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 analyse user behaviour across devices.

We have activated the anonymisation of IP addresses for Google Analytics. Due to IP anonymisation, your IP address will be truncated by Google within member states of the European Union or in other contracting states to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

During your website visit, your user behaviour is recorded in the form of “events”. Events can be:

– Page views
– First visit to the website
– Start of session
– Your “click path”, interaction with the website
– Scrolls (whenever a user scrolls to the bottom of the page (90%))
– Clicks on external links
– Internal search queries
– interaction with videos
– ads seen / clicked on

Also recorded:

– your approximate location (region)
– your IP address (in shortened form)
– technical information about your browser and the end devices you use (e.g. language setting, screen resolution)
– your internet service provider
– the referrer URL (via which website/advertising medium you came to this website)


Purposes of the processing

On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services relating to website activity. The reports provided by Google Analytics are used to analyse the performance of our website [OPTIONAL] and the success of our marketing campaigns.



Recipients of the data are/may be

Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (as processor under Art. 28 GDPR).

Google LLC, 1600 Amphitheatre Parkway Mountain View, CA 94043, USA

Alphabet Inc, 1600 Amphitheatre Parkway Mountain View, CA 94043, USA

It cannot be ruled out that US authorities may access the data stored by Google.


Third country transfer

Insofar as data is processed outside the EU/EEA and there is no level of data protection corresponding to the European standard, we have concluded EU standard contractual clauses with the service provider to establish an appropriate level of data protection. The parent company of Google Ireland, Google LLC, is based in California, USA. A transfer of data to the USA and access by US authorities to the data stored by Google cannot be ruled out. The USA is currently considered a third country from a data protection perspective. You do not have the same rights there as within the EU/EEA. You may not have any legal remedies against access by authorities.


Storage period

The data sent by us and linked to cookies are automatically deleted after two years. Data whose retention period has been reached is automatically deleted once a month.


Legal basis

The legal basis for this data processing is your consent in accordance with Art.6 Para.1 S.1 lit.a GDPR.



You can revoke your consent at any time with effect for the future by calling up the “Cookie settings” button at the bottom of our website and changing your selection there. The lawfulness of the processing carried out on the basis of the consent until the revocation remains unaffected.

Alternatively, you can prevent the storage of cookies from the outset by setting your browser software accordingly. However, if you configure your browser to reject all cookies, functionalities on this and other websites may be restricted. You can also prevent the collection of data generated by the cookie and relating to your use of the website (including your IP address) by Google, and the processing of this data by Google, by

  1. not giving your consent to the setting of the cookie or
  2. downloading and installing the browser add-on to deactivate Google Analytics HERE.

Embedded content

We have embedded third-party content on our website.

a. Google Maps

This site uses the mapping service Google Maps. Google Maps is a mapping service provided by Google LLC, 1600 Amphitheatre Parkway Mountain View, CA 94043, USA. The responsible body for users in the EU/EEA and Switzerland is Google Ireland Limited, Google Building Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland.

In order to use the Google Maps functions, information, including the IP address and the address entered as part of the route function, may be transmitted to the provider’s servers. This information is usually transferred to a Google server in the USA and stored there. When you visit our website that contains Google Maps, your browser, after you have consented to this via our cookie banner, establishes a direct connection with Google’s servers, whereby the map content is sent to your browser and integrated by it. The provider of this site has no influence on this data transmission. According to current knowledge, this includes the following data:

– Date and time of the visit to the website in question,

– Internet address or URL of the website called up,

– IP address, (start) address entered as part of route planning.


Google Maps is used in the interest of an attractive presentation of our online offers and to make it easy to find the places we indicate on the website. If you do not wish Google to process your data via this service, you can deactivate the use of JavaScript in your browser settings. Please note that in this case the interactive map function of Google Maps cannot be used.

Insofar as data is processed outside the European Economic Area / the EU, where there is no level of data protection corresponding to the European standard, Google states that it uses standard contractual clauses.

More information on the handling of user data can be found in Google’s privacy policy:

The collection and storage of data only takes place after explicit consent according to Art. 6 para. 1 p. 1 lit. a) GDPR. This is voluntary and can be revoked at any time with future effect by clicking the “Cookie Settings” button at the bottom of the website and changing your decision.


b. YouTube

We use services from YouTube, LLC, 901 Cherry Ave, 94066 San Bruno, CA, USA, a subsidiary of Google Inc, Amphitheatre Parkway, Mountain View, CA 94043, USA, on our website. For users who are habitually resident in the European Economic Area or Switzerland, Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland is the data controller for your data.

We obtain the consent required for use in accordance with Art. 6 para. 1 p. 1 lit. a GDPR via cookie banner. Your consent is voluntary and can be revoked at any time by returning to the cookie banner via the “Cookie Settings” button at the bottom of the website and changing your decision.

If you have consented, YouTube will set cookies and use your visit data for its own purposes. If you are logged in to YouTube at this time, the information about the videos you have viewed will be assigned to your member account with YouTube. You can prevent this by logging out of your member account before visiting our website. Insofar as data is processed outside the European Economic Area / the EU, where there is no level of data protection corresponding to the European standard, Google states that it uses standard contractual clauses.

Further information on YouTube’s data protection is provided by Google at the following link:


Social Bookmarks

This website uses social bookmarks from the providers:

– LinkedIn (Operator: LinkedIn Ireland Unlimited Company, Wilton Place, Dublin 2, Ireland).
– XING (Operator: New Work SE, Dammtorstraße 30, 20354 Hamburg, Germany)

Social bookmarks are Internet bookmarks with which users of such a service can collect links and news reports. We set these in accordance with Art. 6 para. 1 p. 1 lit. f GDPR. Our legitimate interest lies in the timely communication with our website visitors. The social bookmarks are only integrated on our website as a link to the corresponding services. After clicking on the embedded graphic, you will be redirected to the page of the respective provider, i.e. only then will user information be transmitted to the respective provider. For information on how your personal data is handled when using these websites, please refer to the respective provider’s privacy policy.


Data transfer

As a matter of principle, your data will not be transferred to third parties unless we are legally obliged to do so, or the transfer of data is necessary for the performance of the contractual relationship, or you have previously expressly consented to the transfer of your data.

External service providers and partner companies, such as online payment providers or the shipping company commissioned with the delivery, only receive your data insofar as this is necessary to process your order. In these cases, however, the scope of the transmitted data is limited to the necessary minimum. Insofar as our service providers come into contact with your personal data, we ensure within the framework of order processing pursuant to Art. 28 GDPR that they comply with the provisions of the data protection laws in the same manner. Please also note the respective data protection notices of the providers. The respective service provider is responsible for the content of third-party services, whereby we check the services for compliance with the legal requirements within the scope of reasonableness.

We attach importance to processing your data within the EU / EEA. However, it may happen that we use service providers who process data outside the EU / EEA. In these cases, we ensure that an adequate level of data protection comparable to the standards within the EU is established at the recipient prior to the transfer of your personal data. This can be achieved, for example, via EU standard contracts or Binding Corporate Rules or special agreements to whose regulations the company may be subject.


Data security

LTG AG has taken extensive technical and operational security precautions to protect your data from unauthorised access or misuse. Our security procedures are regularly reviewed and adapted to technological progress. Our employees are regularly trained and committed to confidentiality.


Facebook Fanpage

a. General information

Social media have become an integral part of the internet and modern communication. In order to stay in contact with our customers and interested parties, we have also set up our own fan page on Facebook. Facebook is a service of Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA.

We expressly draw your attention to the fact that Facebook stores the data (e.g. IP address, preferences and personal interests, behaviour on Facebook pages, any personal information stored on Facebook, etc.) of users and uses it for business purposes.

We have no influence on the processing and further use of this data, as Facebook alone determines the processing. To what extent, where and for how long the data is stored, to what extent the data is linked and evaluated and to whom the data is passed on is currently not comprehensible to us. We also have no insight or influence with regard to deletion periods, i.e. whether and to what extent deletion periods are adhered to.

Information from Facebook itself about what information is collected can be found in Facebook’s data protection guidelines, which can be viewed here:

If you are a Facebook member and logged into your Facebook user account, Facebook can associate your visit to our site with your user account. If you would like to prevent Facebook from linking data about your visit to our fan page with your membership data stored on Facebook, you must

– log out of Facebook before each visit to our fan page
– delete the cookies stored on your device
– and close and restart your browser.

In this way, according to Facebook, all information by which you can be identified by Facebook will be deleted.

b. Scope of data collection and storage

You do not need to be a Facebook member to view the content on our Facebook fan page. However, data is collected, stored and used by Facebook every time you visit our page. ln the moment you call up our fan page, your browser establishes a connection with a Facebook server. In doing so, data may be transferred to countries outside the European Union. In any case, regardless of whether you are registered with Facebook or not, your IP address will be transmitted and cookies will be set. If you are a Facebook member and logged into your Facebook user account, Facebook can associate your visit to our site with your user account.

The cookies used include session cookies, which are deleted when the browser is closed, and persistent cookies, which remain on the end device until they expire or are deleted by the user. A cookie is a tiny text file that enables a website to recognise a browser. Cookies are stored on the computer when a website is called up and are retrieved and read the next time the web server is called up.  You can decide yourself via your browser settings whether and which cookies you want to allow, block or delete. Alternatively, you can also install so-called ad blockers, such as Ghostery.

According to Facebook, the cookies used by Facebook are for authentication, security, website and product integrity, advertising and measurement, website features and services, performance, and analytics and research. Details of the cookies used by Facebook (e.g. cookie names, duration of operation, content collected and purpose) can be found here: by following the links there. You can make settings regarding which advertisements are to be displayed or no longer displayed to you by Facebook at and at

Under the aforementioned link, you can manage your preferences regarding usage-based online advertising. If you object to usage-based online advertising with a particular provider using the preference manager, this only applies to the particular business data collection via the web browser you are currently using. The preference management is cookie-based. Deleting all browser cookies will also remove the preferences you have set with the preference manager.

Demographic data (e.g. based on age, place of residence, language or gender)

Art. 6 para. 1 p. 1 lit. f GDPR

Art. 6 para. 1 p. 1 lit. f GDPR

Automated decision-making including profiling pursuant to Art. 22 GDPR does not take place.

As a matter of principle, we only store personal data until the respective purpose for which the data was collected has been achieved. In the context of a business relationship with you, we store your personal data for as long as the business relationship lasts; this also includes the initiation and processing of a contract as well as the regular limitation period. In addition, we store the data if and insofar as we are subject to statutory retention obligations. Such obligations may arise, for example, from the German Commercial Code (HGB) or the German Fiscal Code (AO).

If you have given us consent for a processing operation, the data related to the granting of consent will be stored until revoked or for a long time for the duration of the processing operation and after its termination within the scope of the statute of limitations.

c. Facebook Insights

For statistical evaluation purposes, we use the Facebook Insights function. In this context, we receive anonymised data on the users of our Facebook fan page. It is not possible for us to draw any conclusions about your person. For further information, please refer to Facebook’s cookie policy.

d. Disclosure and use of personal data

If you interact with Facebook, Facebook naturally also has access to your data. In this case, Facebook is located in an insecure third country where the level of data protection is lower. The data transfer is based on the so-called standard data protection clauses. You can find more information on this HERE.

e. Legal basis

If the processing is necessary to protect a legitimate interest of our company or a third party and the interests, fundamental rights and freedoms of the data subject do not outweigh the first-mentioned interest, Art. 6 (1) lit. f GDPR is the legal basis for the processing. We see our legitimate interest for data processing in the presentation of our company and our products as well as services for your information and in particular in the provision of up-to-date communication options for and with you.
