Some of our web pages use cookies. Cookies do not harm your computer and do not contain viruses. Cookies serve to make our website more user-friendly, effective and secure. Cookies are small text files that are stored on your computer and saved by your browser.
Most of the cookies we use are so-called ‘session cookies’. They are automatically deleted at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognise your browser the next time you visit.
You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when you close your browser. If you deactivate cookies, the functionality of this website may be restricted.
Cookies that are necessary for the electronic communication process or to provide certain functions you have requested (e.g. shopping basket function) are stored on the basis of Art. 6 para. 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.
Analytical cookies enable us to collect data in aggregate form about our website visitors and their experiences on our website. We use this data to eliminate errors and improve the experience for all visitors. Insofar as other cookies (e.g. cookies for analysing your surfing behaviour) are stored, the processing of your personal data is based on consent in accordance with Art. 6 para. 1 lit. a GDPR. Insofar as other cookies (e.g. cookies for analysing your surfing behaviour) are stored, these are treated separately in this privacy policy.
The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:
This data is not merged with other data sources.
The basis for data processing is Art. 6 (1) lit. f GDPR, which permits the processing of data for the fulfilment of a contract or pre-contractual measures.
We reserve the right to subsequently check this data or have it checked if we become aware of specific indications of illegal use.
The temporary storage of the IP address by the system is necessary to enable the website to be accessed. For this purpose, the IP address of the user (visitor) must remain stored for the duration of the session. Storage in log files serves to optimise the website and to ensure the security of our information technology systems. The data is not evaluated for marketing purposes in this context.
The data is deleted as soon as it is no longer required for the purpose for which it was collected. In the case of data collection for the provision of the website, this is the case when the respective session has ended.
If the data is stored in log files, it will be deleted after seven days at the latest. Storage beyond this period is possible (e.g. for security reasons, such as to investigate misuse or fraud, or for storage for evidence purposes). In this case, the IP addresses of the users are deleted or alienated so that it is no longer possible to assign them to the calling client.
The collection of data for the provision of the website and the storage of data in log files is essential for the operation of the website. Consequently, there is no possibility for the user to object.
If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you provided there, will be stored by us for the purpose of processing the enquiry and in case of follow-up questions. We will not pass on this data without your consent.
When the message is sent, the following data is also stored:
Alternatively, you can contact us via the email address provided. In this case, the user's personal data transmitted with the email will be stored.
The processing of the data entered in the contact form is therefore based exclusively on your consent (Art. 6 para. 1 lit. a GDPR). The legal basis for the processing of data transmitted in the course of sending an email is also Art. 6 para. 1 lit. f GDPR. If the email contact is aimed at concluding a contract, the additional legal basis for processing is Art. 6 para. 1 lit. b GDPR.
The processing of personal data from the input mask serves us solely for the purpose of processing the contact request. In the case of contact by email, this also constitutes the necessary legitimate interest in the processing of the data.
The other personal data processed during the sending process serves to prevent misuse of the contact form and to ensure the security of our information technology systems.
You can revoke this consent at any time. To do so, simply send us an informal email. The legality of the data processing operations carried out until revocation remains unaffected by the revocation.
The data you enter in the contact form will remain with us until you request us to delete it, revoke your consent to its storage, or the purpose for data storage no longer applies (e.g. after your enquiry has been processed). Mandatory legal provisions – in particular retention periods – remain unaffected.
The additional personal data collected during the sending process will be deleted after a period of seven days at the latest.
You can register on our website to use additional features on the site. We only use the data you enter for the purpose of using the respective offer or service for which you have registered. The mandatory information requested during registration must be provided in full. Otherwise, we will reject the registration.
When the message is sent, the following data is also stored:
For important changes, such as changes to the scope of the offer or technically necessary changes, we will use the email address provided during registration to inform you.
The data entered during registration is processed on the basis of your consent (Art. 6 (1) (a) GDPR). You can revoke your consent at any time. To do so, simply send us an informal email. The legality of the data processing already carried out remains unaffected by the revocation.
The data collected during registration will be stored by us for as long as you are registered on our website and will then be deleted. Statutory retention periods remain unaffected.
The additional personal data collected during the sending process will be deleted after a period of seven days at the latest.
This website uses Google Tag Manager from Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; ‘Google’). We use this to manage our analysis services as described above. Google Tag Manager only implements tags. This means that no cookies are used and no personal data is collected. Google Tag Manager triggers other tags, which in turn may collect data. However, Google Tag Manager does not access this data. If deactivation has been carried out at domain or cookie level, it remains in place for all tracking tags, provided they are implemented with Google Tag Manager.
For more information about Google Tag Manager, please visit:

We integrate maps from the Google Maps service provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA, in order to visually display geographical information. The operator in the EU is Google Ireland Limited (Google), Gordon House, Barrow Street, Dublin 4, Ireland. When using Google Maps, Google also processes data about the use of the map functions by visitors to the website. Google may transfer the information obtained through Maps to third parties if required by law or if third parties process this data on behalf of Google. Google will never associate your IP address with other data from Google. Nevertheless, it would be technically possible for Google to identify at least individual users based on the data received. It is possible that personal data and personality profiles of website users could be processed by Google for other purposes over which we have no influence and cannot influence. Further information about data processing by Google can be found at https://www.google.com/policies/privacy/, opt-out: https://adssettings.google.com/authenticated. In Google's ‘Privacy Centre’, users can change their individual settings so that their own data can be managed and protected (https://support.google.com/accounts/answer/3024190).
By using this website, you consent to the collection, processing and use of automatically collected data by Google Inc, its representatives and third parties. Your data will be processed on the basis of your consent in accordance with Art. 6 (1) (a) GDPR.

This website uses functions of the web analysis service Google Analytics. The provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.
Google Analytics uses so-called ‘cookies’. These are text files that are stored on your computer and enable an analysis of your use of the website. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there.
The storage of Google Analytics cookies is based on Art. 6 para. 1 lit. a GDPR.
We have activated the IP anonymisation function on this website. This means that your IP address will be truncated by Google within member states of the European Union or in other states party to the Agreement on the European Economic Area before being transmitted to the United States. Only in exceptional cases will the full IP address be transmitted to a Google server in the United States and truncated there. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide other services relating to website activity and internet usage to the website operator. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.
You can prevent cookies from being stored by adjusting your browser software settings accordingly; however, we would like to point out that in this case you may not be able to use all the functions of this website to their full extent. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the website (including your IP address) and from processing this data by downloading and installing the browser plugin available at the following link: https://tools.google.com/dlpage/gaoptout?hl=de.
You can prevent Google Analytics from collecting your data by clicking on the following link. An opt-out cookie will be set to prevent your data from being collected on future visits to this website: Disable Google Analytics.

Scope of personal data processing
We use the open source software tool Matomo (formerly PIWIK) on our website to analyse the surfing behaviour of our users. The software places a cookie on the user's computer (see above for information on cookies). When individual pages of our website are accessed, the following data is stored.
Two bytes of the IP address of the user's accessing system
The software runs exclusively on our website's servers. Users' personal data is only stored there. The data is not passed on to third parties.
The software is set up so that IP addresses are not stored in full, but rather 2 bytes of the IP address are masked (e.g. 192.168.xxx.xxx). This means that it is no longer possible to assign the truncated IP address to the requesting computer.
The legal basis for the processing of users' personal data is consent in accordance with Art. 6 (1) (a) GDPR.
The processing of users' personal data enables us to analyse the surfing behaviour of our users. By evaluating the data obtained, we are able to compile information about the use of the individual components of our website. This helps us to continuously improve our website and its user-friendliness. These purposes also constitute our legitimate interest in processing the data in accordance with Art. 6(1)(f) GDPR. The anonymisation of the IP address takes sufficient account of the users' interest in the protection of their personal data.
The data will be deleted as soon as it is no longer required for our recording purposes, at the latest after 6 months.
Cookies are stored on the user's computer and transmitted by the user to our site. Therefore, as a user, you have full control over the use of cookies. By changing the settings in your internet browser, you can deactivate or restrict the transmission of cookies. Cookies that have already been stored can be deleted at any time. This can also be done automatically. If cookies are deactivated for our website, it may no longer be possible to use all the functions of the website to their full extent.
We offer you the option of opting out of the analysis process on our website. To do this, you must read the text of the following paragraph and tick the box. This will set another cookie on your system that signals to our system not to store the user's data. If the user deletes the corresponding cookie from their own system in the meantime, they must set the opt-out cookie again.
For more information on the privacy settings of the Matomo software, please visit the following link: https://matomo.org/docs/privacy.
On this website, we use the tool ‘FriendlyCaptcha’, which is provided by FriendlyCaptcha GmbH, Am Anger 3-5, 82237 Wörthsee, Germany. To protect the website from spam and misuse, this tool is used for all contact forms. The tool serves to distinguish whether the data entered in the contact form was entered by a natural person or whether it was misused by a machine and automated processing. By using FriendlyCaptcha, we can block automated software.
The data is used exclusively for the protection against spam and bots described above. Friendly Captcha does not set or read any cookies on the visitor's device. IP addresses are only stored in hashed (one-way encrypted) form and do not allow us or Friendly Captcha to identify an individual. If personal data is collected, it will be deleted after 30 days at the latest.
Further information on data protection when using Friendly Captcha can be found at: https://friendlycaptcha.com/de/legal/privacy-end-users/ Google reCAPTCHA
We use ‘Google reCAPTCHA’ (hereinafter “reCAPTCHA”) on our websites. The provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (‘Google’).
reCAPTCHA is used to check whether the data entered on our websites (e.g. in a contact form) is entered by a human or by an automated programme. To do this, reCAPTCHA analyses the behaviour of the website visitor based on various characteristics. This analysis starts automatically as soon as the website visitor enters the website. reCAPTCHA evaluates various information for the analysis (e.g. IP address, length of time spent on the website or mouse movements made by the user). The data collected during the analysis is forwarded to Google.
The reCAPTCHA analyses run entirely in the background. Website visitors are not notified that an analysis is taking place.
Data processing is carried out on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in protecting its web offerings from abusive automated spying and spam. If corresponding consent has been requested (e.g. consent to the storage of cookies), processing is carried out in accordance with Art. 6 para. 1 lit. a GDPR.
Further information on Google reCAPTCHA and Google's privacy policy can be found at the following links: https://www.google.com/intl/de/policies/privacy and https://www.google.com/recaptcha/intro/android.html.
The controller processes the personal data of job applicants solely for the purpose of handling the application process and in accordance with legal requirements. Processing may also be carried out electronically. This is particularly the case if an applicant submits the relevant application documents to the controller electronically, for example by email.
If the controller concludes an employment contract with an applicant, the data transmitted will be stored for the purpose of processing the employment relationship in compliance with the statutory provisions. If the controller does not conclude an employment contract with the applicant, the application documents will be automatically deleted six months after notification of the rejection decision, provided that no other legitimate interests of the controller prevent deletion or the applicant has given their consent to further processing. Other legitimate interests in this sense include, for example, the obligation to provide evidence in proceedings under the General Equal Treatment Act (AGG). Invoices for any travel expense reimbursements will be archived in accordance with tax law requirements.
By submitting their application to us, applicants consent to the processing of their data for the purposes of the application process in accordance with the manner and scope set out in this privacy policy.
The processing of applicant data is carried out to fulfil our (pre-)contractual obligations within the framework of the application process in accordance with Art. 6 (1) lit. b GDPR; the application addressed to the controller is made on a voluntary basis by the applicant in accordance with Art. 6 (1) lit. a GDPR.
1. Cooperation with processors and third parties
If, in the course of our processing, we disclose data to other persons and companies (processors or third parties), transfer it to them or otherwise grant them access to the data, this will only be done on the basis of a legal permission (e.g. if the transfer of data to third parties, such as payment service providers, is necessary for the performance of a contract in accordance with Art. 6 para. 1 lit. b GDPR), if you have given your consent, if a legal obligation provides for this or on the basis of our legitimate interests (e.g. when using agents, web hosts, etc.).
If we commission processors to process data, this is done on the basis of Art. 28 GDPR.
2. Transfers to third countries
If we process data in a third country (i.e. outside the European Union (EU) or the European Economic Area (EEA)) or if this occurs in the context of using third-party services or disclosing or transferring data to third parties, this will only take place if it is necessary for the fulfilment of our (pre)contractual obligations, on the basis of your consent, due to a legal obligation or on the basis of our legitimate interests. Subject to legal or contractual permissions, we only process or have the data processed in a third country if the special requirements of Art. 44 ff. GDPR are met. This means that processing is carried out, for example, on the basis of special guarantees, such as the officially recognised determination of a level of data protection equivalent to that of the EU or compliance with officially recognised special contractual obligations (so-called ‘standard contractual clauses’).
3. Integration of third-party services and content
We use content or services from third-party providers within our online offering in order to integrate their content and services, such as videos or fonts (hereinafter referred to collectively as ‘content’).
This always requires that the third-party providers of this content recognise the IP address of the users, as they would not be able to send the content to their browsers without the IP address. The IP address is therefore necessary for the display of this content. We endeavour to use only content whose respective providers use the IP address solely for the delivery of the content. Third-party providers may also use so-called pixel tags (invisible graphics, also known as ‘web beacons’) for statistical or marketing purposes. Pixel tags can be used to evaluate information such as visitor traffic on the pages of this website. The pseudonymous information may also be stored in cookies on the user's device and may include technical information about the browser and operating system, referring websites, visit time and other information about the use of our online offering, and may also be linked to such information from other sources.
4. Webhosting
The hosting services we use serve to provide the following services: infrastructure and platform services, computing capacity, storage space and database services, security services and technical maintenance services, which we use for the purpose of operating this online offering.
In doing so, we or our hosting provider process inventory data, contact data, content data, contract data, usage data, meta and communication data from customers, interested parties and visitors to this online service on the basis of our legitimate interests in the efficient and secure provision of this online service in accordance with Art. 6 (1) lit. f GDPR in conjunction with Art. 28 GDPR (conclusion of a contract for order processing).
5. Data protection on third-party websites
This website may contain hyperlinks to third-party websites. If you follow a hyperlink to one of these websites, please note that we cannot accept any responsibility or liability for third-party content or data protection conditions. Please check the applicable data protection conditions before submitting personal data to these websites. The operators of linked sites are solely responsible for their content. When the links were created, there was no indication that the content of the linked pages was illegal or immoral. Please notify us immediately if a third-party website to which we link does not or no longer complies with legal requirements or morality. The licence and terms of use of the respective operators of the website apply.
1. SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or enquiries that you send to us as the site operator. You can recognise an encrypted connection by the fact that the address line of the browser changes from ‘http://’ to ‘https://’ and by the lock symbol in your browser line.
If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.
2. Objection to advertising emails
We hereby object to the use of contact details published in accordance with the legal notice requirement for the purpose of sending unsolicited advertising and information material. The operators of these pages expressly reserve the right to take legal action in the event of unsolicited advertising information being sent, for example in the form of spam emails.
3. Changes to our data protection provisions
We change our security and data protection measures as required by technical and legal developments and adapt our data protection guidelines accordingly. Please therefore refer to the current version.
