Privacy Policy

Data protection

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with statutory data protection regulations and this Privacy Policy.

The use of our website is generally possible without providing personal data. If personal data (for example name, address, or email addresses) is collected on our web pages, this always takes place to the extent possible on a voluntary basis. This data is not shared with third parties without your express consent.

Please note that the transfer of data on the internet (for example via email communication) may have security gaps. Gap-free protection of the data from access by third parties is not possible.


We are using cookies on our website. Cookies are small amounts of data as textual information, that the webserver sends to your browser. Cookies are stored on your computer. Cookies can only be read by the server that has previously stored them. Cookies do not save any personal information like your name. The data stored in cookies are not being connected to your personal data (name, address etc.).

It is up to you whether you allow cookies. There are several ways to disallow cookies. For example you can change the settings of your browser (usually under “Settings” or “Options”) to accept all cookies, to be informed when cookies are stored or to reject all cookies. Additionally, you can always delete cookies that have been stored at any time. This can also be done automatically. If you reject technically necessary cookies on our website, our website might not work or appear as intended. Beyond that, you can use the cookie banner on our website to accept tracking and performance and marketing cookies.

We use so called cookies on our website. Generally, there are transistent and persistent cookies.

Transistent cookies are deleted automatically when you close your browser. Especially session cookies are part of this category. These store a so called session ID which allows to assign different browser requests to the same session. This allows your computer to be recognized when you return to our website. Session cookies are deleted when you log out or when you close your browser.

Currently, we are not using transistent cookies.

We are using persistent cookies that are used to provide features like a livechat and that can be used to store decisions the user made or to analyze the behavior of visitors on a website. Persistent cookies are deleted automatically after a set amount of time. This amount of time can vary between cookies. Persistent cookies can be used to transmit data like:

  1. IP address
  2. Search terms
  3. Utilization of Website functionality

We are using these persistent cookies on our website.

  • Strictly necessary cookies:
    • lhnAutoInviteShown to provide a livechat (validity: 1 hour)
    • lhnContact to provide a livechat (validity: 2 years)
    • lhnJWT to provide a livechat (validity: 1 day)
    • lhnRefresh to provide a livechat (validity: 1 week)
    • cookie_consent_level to save your cookie preferences (validity: 1 year)
    • cookie_consent_user_accepted to save whether you have saved cookie preferences (validity: 1 year)
  • Tracking cookies:
    • _gat_UA-XYZ to communicate with Google Analytics (validity: 1 minute)
    • _ga to identify visitors (validity: 2 years)
    • _gcl_au to communicate with GoogleAds (validity: 90 days)
    • _gid to track the behavior of visitors (validity: 24 hours)

The legal basis for processing personal data by using strictly necessary cookies is art. 6 section 1 sentence 1 lit. f GDPR. The reason and usage of cookies is to simplify the usage of the website. Some functions of our website cannot be provided without the usage of cookies. For those it is necessary that the browser can be recognized after changing the page. The acquisition of personal data through strictly necessary cookies is not used to create user profiles.

Data that is acquired through persistent tracking cookies gets pseudo-anonymized. Therefore, it is not possible to map the data with the visiting person. The data is not stored with other personal data.

You have to actively accept persistent tracking cookies through the cookie banner on our website. Legal basis for using such cookies on your device and the following processing of the information is, if consent was given according to article 6 section 1 sentence 1 lit. a GDPR, article 5 section 3 ePrivacy guideline.

You can revoke your previously given consent at any time by using the “Cookie Settings” link in the footer of this website.

Server log files

The provider of the web pages automatically collects and stores information in the server log files that your browser transfers to us automatically. These are:

  • Browser type and version
  • Operating system used
  • Referring URL
  • Hostname of the accessing computer
  • Time of the server request

This data cannot be assigned to specific persons. A combination of this data with other data sources is not performed. We reserve the right to review this data at a later time if we become aware of any concrete indications of unlawful use.

Live chat, contact form and e-mail contact

Our website allows you to receive live support. If no support staff are currently available, however, then you can also leave a message. If a user takes advantage of this option, the data entered in the contact form will be transmitted to us and stored. This data is:

  1. For live support: only the data that is required for your individual support request, such as your IP address, or data that you voluntarily provide in a note/comment,
  2. “Leave a Message”: Name, e-mail address and your message (if this contains personal information from you that you voluntarily provide).

On our website we also have provided contact forms for your convenience, which you can use to contact us electronically and send us your request. We only use the contact form to collect your name and either your e-mail address or telephone number. For general requests it is mandatory to provide an e-mail address while the telephone number is voluntarily. Requests concerning trainings require a telephone number, but not an e-mail address. Submission of your phone number is voluntary. Your IP address will also be stored at the time that you submit your message. The difference in mandatory information for the contact forms is based on our assumption that requests about trainings are more concrete than general requests. Therefore, a telephone number makes more sense.

Before the data is processed, you will be informed of the intended use of your data that is collected from the “Leave a message” feature and the contact form during the sending process, and you will be directed to review this privacy policy.

Alternatively, you can contact us via the e-mail address provided on our website. In this case, the user's personal data that is transmitted with the e-mail will be stored.

No data is disclosed to third parties in this context. The data is used exclusively for processing the conversation.

The legal basis for the processing of the data transmitted when you send an e-mail is Article 6 (1) (f) GDPR. If an e-mail is sent with the intent of concluding a contract, then the additional legal basis for the processing is Article 6 (1) (b) GDPR.

We only process data that is collected from the contact form for purposes of processing the contact request. This also constitutes our necessary legitimate interest for processing the data.

The other personal data that is processed during the sending process is used to prevent misuse of the contact form and to ensure the security of our information technology systems.

The data will be deleted as soon as it is no longer necessary to achieve the purpose for which it was collected. This is the case when the respective conversation with the user has ended for personal data that was collected from the contact form, the live chat and messages that are left via the “Leave a message” feature. The conversation ends when it can be inferred from the circumstances that the matter in question has been finally clarified.

The chat is only saved to so-called RAM (Random Access Memory), and it is usually immediately deleted as soon as we or you have finished the chat conversation, but in no case later than 2 hours after the last message in the chat history. Cookies are stored on your device in order to enable the chat function.

The additional personal data that is collected during the sending process will be deleted at the latest after a period of seven days.

Right to objection:

You have the opportunity to object to the processing of your personal data at any time. For this please use the contact options listed above. If you contact us by e-mail and object to the storage of your personal information, the conversation may not continue.

All personal data that has been stored in the course of establishing contact will be deleted in this case.

Data protection information for the application process

We process the data of applicants only for the purpose and within the scope of the application procedure in accordance with the legal requirements. The processing of applicant data is carried out to meet our (pre)contractual obligations within the framework of the application procedure as defined in Art. 6 Para. 1 (b) and (f) GDPR, if the data processing becomes necessary for us e.g. in the context of legal proceedings (in Germany Sec. 26 of the German Data Protection Act (BDSG) additionally applies).

The application procedure requires that applicants provide us with the applicant data. The necessary applicant data is indicated on the online form, otherwise it can be found in the job description and generally includes personal details, postal and contact addresses and documents that are part of the application package, such as cover letter, curriculum vitae and certificates. In addition, applicants may voluntarily provide us with additional information.

With the submission of the application to us, the applicants agree to the processing of their data for application purposes in accordance with the type and scope set out in this privacy policy.

If special categories of personal data within the meaning of Art. 9 Para. 1 GDPR are voluntarily disclosed in the application process, they will also be processed in accordance with Art. 9 Para. 2 (b) GDPR (e.g. health data, such as severely disabled status or ethnic origin). If special categories of personal data within the meaning of Art. 9 Para. 1 GDPR are requested from applicants as part of the application procedure, they will also be processed in accordance with Art. 9 Para. 2 (a) GDPR (e.g. health data if pertinent for the exercise of a profession).

If made available, applicants can submit their applications via an online form on our website. The data will be transmitted to us in encrypted form in accordance with the latest technology. Applicants can also send us their applications by e-mail. Please note, however, that e-mails are generally not sent in encrypted form and the applicants themselves must ensure that they are encrypted. Consequently, we are unable to accept any responsibility for the transmission of the application from the sender to the recipient on our server and therefore recommend that you use an online form or postal delivery. Instead of applying via the online form and e-mail, applicants also have the option of sending their application by post

Otherwise, if the application for a job offer is not successful, the applicant's data will be deleted. The data of the applicants will also be deleted if an application is withdrawn, which applicants are entitled to do at any time.

The deletion takes place, subject to a justified revocation by the applicant, after the expiry of a period of six months, in order for us to be able to answer any follow-up questions regarding the application and meet our obligation to provide evidence under the Equal Treatment Act. Invoices for any reimbursement of travel expenses are archived in accordance with tax regulations.

Usually, the information about your usage of our website, that are collected by cookies, are transmitted to and stored on a Google server in the United States of America.

Only in exceptional cases your full IP address is transmitted into the USA and shortened there. On our account Google uses this information, to analyze your usage of our website, to create reports about activities on our website and to provide additional services for us as the operator of the website that are related to the usage of the internet. The IP address that is transmitted within the context of Google Analytics through your browser is not brought together with other data from Google. You can prevent the storage of cookies by applicable settings in your browser or by declining tracking cookies in the cookie banner, which is available through the “Cookie Settings” link in the footer .

Contracted data processing

We have concluded a contract with Google for data processing and fully implement the strict requirements of the German data protection authorities with our use of Google Analytics.

Google Analytics demographics data

This website uses the “Demographics” function of Google Analytics. This allows reports to be generated that contain data on the age, gender, and interests of website visitors.

This data is derived from interest-driven advertisement by Google as well as visitor data from third party providers. This data cannot be assigned to a specific person.

Google AdWords and Conversion Measurement

We use the services of Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”) on the basis of our legitimate interests (i.e., interest in the analysis, optimization and economic operation of our online service within the meaning of Art. 6 para. 1 letter f GDPR).

Google is certified under the Privacy Shield Agreement, providing a guarantee to comply with European privacy legislation (

We use Google's online AdWords marketing tool to place ads on the Google advertising network (e.g., in search results, in videos, on websites, etc.) so that they are displayed to users who have an assumed interest in the ads. This allows us to more specifically display ads for and within our online service so that we only present ads to users that potentially match their interests. For example, if a user sees ads for products he's been looking for on other online services, that's called “remarketing.” For these purposes, upon access to our and other websites where the Google advertising network is active, Google will immediately execute a Google code and “(re)marketing tags” (invisible graphics or code, also known as “web beacons”) will be incorporated into the website. With their help, an individual cookie, i.e., a small file (comparable technologies can also be used instead of cookies) is stored on the user’s device. This file (the “cookie”) notes which websites the user has visited, in what content he is interested, and on what offers he has clicked, as well as technical information about the browser and operating system, referring websites, time of visit and other information on the use of the online service.

In addition, we receive an individual “conversion cookie.” The information obtained through this cookie is used by Google to generate conversion statistics for us. However, we only learn the anonymous total number of users who clicked on our ad and were redirected to a conversion tracking tag page. We do not receive any information that personally identifies users.

User data is processed pseudonymously within the Google advertising network. For example, Google does not store and process users’ names or e-mail addresses, but processes the relevant data in a cookie-related manner within pseudonymous user profiles. In other words, from Google’s perspective the ads are not managed and displayed to a specifically identified person, but to the cookie owner, regardless of who the cookie owner is. This does not apply if a user has expressly allowed Google to process the data without this pseudonymization. The information collected about the user is transmitted to Google and stored on Google's servers in the United States.

For more information about Google's data usage, settings and objection options, please refer to Google's Privacy Policy ( ) and the settings for the display of advertisements by Google (

Google reCAPTCHA

We include the reCaptcha service by Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”) on this website.

The legal basis for this transmission of the data is art. 6 section 1 sentence 1 lit. f GDPR. It is based on our legitimate interest in the individual autonomy in the internet and in the prevention of abusive usage and spam. The usage of Google reCAPTCHA can also result in a transmission of data to servers of Google LLC. in the USA.

In the case of transmission of personal data to Google LLC. in the USA, Google LLC. is certified under the Privacy Shield agreement, which provides an additional guarantee to comply with European privacy legislation when processing data in the US:
