In the following, we provide information about the collection of personal data when using our website. Personal data is all data that can be related to you personally, e.g. name, address, e-mail addresses, user behaviour, IP address.

The controller pursuant to Art. 4 para. 7 EU General Data Protection Regulation (GDPR) and other national data protection laws of the member states as well as other data protection regulations is the:

The data protection officer of the controller is

We collect and use our users' personal data only to the extent necessary to provide a functional website and our content and services. The collection and use of our users' personal data only takes place regularly with the user's consent. An exception applies in cases where it is not possible to obtain prior consent for factual reasons and the processing of the data is permitted by law.

Insofar as we obtain the consent of the data subject for the processing of personal data, Art. 6 para. 1 lit. a EU General Data Protection Regulation (GDPR) serves as the legal basis for the processing of personal data.

When processing personal data that is necessary for the fulfilment of a contract to which the data subject is a party, Art. 6 para. 1 lit. b GDPR serves as the legal basis. This also applies to processing operations that are necessary for the performance of pre-contractual measures. Insofar as the processing of personal data is necessary to fulfil a legal obligation to which our company is subject, Art. 6 para. 1 lit. c GDPR serves as the legal basis.

In the event that vital interests of the data subject or another natural person require the processing of personal data, Art. 6 para. 1 lit. d GDPR serves as the legal basis.

If the processing is necessary to safeguard a legitimate interest of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not outweigh the former interest, Art. 6 para. 1 lit. f GDPR serves as the legal basis for the processing.

The personal data of the data subject will be deleted or blocked as soon as the purpose of storage no longer applies. Data may also be stored if this has been provided for by the European or national legislator in EU regulations, laws or other provisions to which the controller is subject. The data will also be blocked or erased if a storage period prescribed by the aforementioned standards expires, unless there is a need for further storage of the data for the conclusion or fulfilment of a contract.

In some cases, we use external service providers to process your data on our website. These have been carefully selected and commissioned by us. They are bound by our instructions and are regularly monitored. Data is not transferred to countries outside the EU or the EEA (so-called third countries).

Each time our website is accessed, our system automatically collects data and information from the computer system of the accessing computer. When using the website for information purposes only, we only collect the personal data that your browser transmits to our server. The following data is collected:

• Browser type and browser version

• Operating system used

• Referrer URL

• About URL

• Host name of the accessing computer

• Time of the server request

• IP-address

• Distinction between desktop computer and mobile device

• Clicks on the website and related categorisation

The data is also stored in the log files of our system. This does not affect the user's IP addresses or other data that allows the data to be assigned to a user. This data is not stored together with other personal data of the user.

The legal basis for the temporary storage of data is Article 6(1)(f) GDPR.

The temporary storage of the IP address by the system is necessary to enable the website to be delivered to the user's computer. For this purpose, the user's IP address must remain stored for the duration of the session.

These purposes also constitute our legitimate interest in data processing in accordance with Article 6(1)(f) GDPR.

The data is deleted as soon as it is no longer required to fulfil the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.

The collection of data for the provision of the website and the storage of data in log files is absolutely necessary for the operation of the website. Consequently, there is no possibility for the user to object to this

Our website uses cookies. Cookies are text files that are stored in the Internet browser or by the Internet browser on the user's computer system. When a user accesses a website, a cookie may be stored on the user's operating system. This cookie contains a characteristic string of characters that enables the browser to be uniquely identified when the website is called up again.

We use cookies to make our website more user-friendly. Some elements of our website require that the accessing browser can be identified even after a page change.

The legal basis for the temporary storage of data is Article 6(1)(f) GDPR.

The purpose of using technically necessary cookies is to simplify the use of websites for users. Some functions of our website cannot be offered without the use of cookies. For these, it is necessary for the browser to be recognised even after a page change.

The user data collected by technically necessary cookies is not used to create user profiles.

These purposes also constitute our legitimate interest in the processing of personal data in accordance with Article 6(1)(f) GDPR.

Cookies are stored on the user's computer and transmitted by it to our website. As a user, you therefore have full control over the use of cookies. You can deactivate or restrict the transmission of cookies by changing the settings in your Internet browser. Cookies that have already been saved 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.

There is a contact form on our website that can be used to contact us electronically. If a user makes use of this option, the data entered in the input mask will be transmitted to us and stored.

Your consent is obtained for the processing of the data as part of the sending process and reference is made to this privacy policy.

Alternatively, it is possible to contact us via the e-mail address provided. In this case, the user's personal data transmitted with the e-mail will be stored.

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

The legal basis for the processing of the data is Art. 6 para. 1 lit. a GDPR if the user has given consent.

The legal basis for the processing of data transmitted in the course of sending an email is Article 6(1)(f) GDPR. If the e-mail contact is aimed at the conclusion of a contract, the additional legal basis for the processing is Art. 6 para. 1 lit. b GDPR.

The processing of the personal data from the input mask serves us solely to process the contact. If you contact us by email, this also constitutes the necessary legitimate interest in processing the data.

The other personal data 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 is deleted as soon as it is no longer required to fulfil the purpose for which it was collected. For the personal data from the input screen of the contact form and those sent by email, this is the case when the respective conversation with the user has ended. The conversation is ended when it can be inferred from the circumstances that the matter in question has been conclusively clarified.

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

The user has the option to withdraw their consent to the processing of personal data at any time. If the user contacts us by e-mail, they can object to the storage of their personal data at any time. In such a case, the conversation cannot be continued. The cancellation can be made informally and should be addressed to the controller.

All personal data stored in the course of making contact will be deleted in this case. Mandatory statutory provisions - in particular retention periods - remain unaffected.

This website uses Google Analytics, a web analytics service provided by Google Inc ("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyse how users use the site. 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. However, if IP anonymisation is activated on this website, your IP address will be shortened by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area beforehand. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and truncated there. Google will use this information on behalf of the operator of this website to analyse your use of the website, to compile reports on website activity and to provide the website operator with other services relating to website activity and internet usage.

The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

This website uses Google Analytics with the extension "_anonymiseIp()". This means that IP addresses are further processed in abbreviated form, so that they cannot be linked to a specific person. If the data collected about you is personally identifiable, it is immediately excluded and the personal data is deleted immediately.

The legal basis for the processing of personal data using cookies for analysis purposes is Art. 6 para. 1 lit. a GDPR if the user has given consent to this.

We use Google Analytics to analyse and regularly improve the use of our website. We can use the statistics obtained to improve our offer and make it more interesting for you as a user. By clicking on "Confirm selection" for analytical cookies or "Select all & confirm" in our cookie consent banner, you also consent in accordance with Art. 49 para. 1 sentence 1 lit. a GDPR,  for the exceptional cases in which personal data is transferred to the USA. The USA is considered by the European Court of Justice to be a country with an inadequate level of data protection according to EU standards. In particular, there is a risk that your data may be processed by US authorities for control and monitoring purposes, possibly without the possibility of legal recourse. If you click on "Accept only necessary cookies", the transmission described above will not take place.

You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. 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 Google by downloading and installing the browser plug-in available at the following link: https://tools.google.com/dlpage/gaoptout?hl=de.

We have concluded an order processing contract with Google and fully implement the strict requirements of the German data protection authorities when using Google Analytics.

Google Dublin, Google Ireland Ltd, Gordon House, Barrow Street, Dublin 4, Ireland, Fax: +353 (1) 436 1001. Terms of use: https://marketingplatform.google.com/about/analytics/terms/de/, overview of data protection: https://policies.google.com/privacy?hl=de, as well as the privacy policy: https://policies.google.com/privacy?hl=de&gl=en.

Our websites use the functions of Google Analytics Remarketing in conjunction with the cross-device functions of Google AdWords and Google DoubleClick. The provider is Google Ireland Ltd, Gordon House, Barrow Street, Dublin 4, Ireland.

This function makes it possible to link the advertising target groups created with Google Analytics Remarketing with the cross-device functions of Google AdWords and Google DoubleClick. In this way, interest-based, personalised advertising messages that have been adapted to you depending on your previous usage and surfing behaviour on one end device (e.g. mobile phone) can also be displayed on another of your end devices (e.g. tablet or PC).

If you have given your consent, Google will link your web and app browsing history to your Google account for this purpose. In this way, the same personalised advertising messages can be displayed on every device on which you sign in with your Google account.

To support this function, Google Analytics collects Google-authenticated user IDs that are temporarily linked to our Google Analytics data in order to define and create target groups for cross-device advertising.

You can permanently object to cross-device remarketing/targeting by deactivating personalised advertising in your Google account by following this link: https://adssettings.google.com.

The aggregation of the data collected in your Google Account is based solely on your consent, which you can give or withdraw from Google (Art. 6 para. 1 lit. a GDPR). For data collection processes that are not merged in your Google account (e.g. because you do not have a Google account or have objected to the merging), the collection of data is also based on your consent  in accordance with Art. 6 para. 1 lit. a GDPR.

Further information and the data protection provisions can be found in Google's privacy policy at https://policies.google.com/technologies/ads.

This website uses Google AdWords. AdWords is an online advertising programme of Google Ireland Ltd, Gordon House, Barrow Street, Dublin 4, Ireland ("Google").

As part of Google AdWords, we use what is known as conversion tracking. When you click on an advert placed by Google, a cookie is set for conversion tracking. Cookies are small text files that the Internet browser stores on the user's computer. These cookies lose their validity after 30 days and are not used to personally identify the user. If the user visits certain pages of this website and the cookie has not yet expired, Google and we can recognise that the user clicked on the ad and was redirected to this page.

Each Google AdWords customer receives a different cookie. The cookies cannot be tracked via the websites of AdWords customers. The information collected using the conversion cookie is used to generate conversion statistics for AdWords customers who have opted for conversion tracking. Customers are told the total number of users who clicked on their advert and were redirected to a page with a conversion tracking tag. However, they do not receive any information that can be used to personally identify users. If you do not wish to participate in tracking, you can object to this use by easily deactivating the Google Conversion Tracking cookie via your Internet browser under user settings. You will then not be included in the conversion tracking statistics.

The storage of "conversion cookies" is based on your consent in accordance with Art. 6 para. 1 lit. a GDPR.

You can find more information about Google AdWords and Google Conversion Tracking in Google's privacy policy: https://policies.google.com/privacy.

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 closing the browser. If cookies are deactivated, the functionality of this website may be restricted.

You can subscribe to a free newsletter on our website. When you register for the newsletter, the data from the input screen is transmitted to us.

The only mandatory information for sending the newsletter is your e-mail address. The provision of further, separately marked data is voluntary and is used to address you personally. After your confirmation, we will save your e-mail address for the purpose of sending you the newsletter.

As part of the registration process, your consent is obtained for the processing of the data and reference is made to this privacy policy. We use the so-called double opt-in procedure to subscribe to our newsletter. This means that after you have registered, we will send you an email to the email address you have provided in which we ask you to confirm that you wish to receive the newsletter. If you do not confirm your registration within 24 hours, your information will be blocked and automatically deleted after one month. We also store the IP addresses you use and the times of registration and confirmation. The purpose of this procedure is to be able to prove your registration and, if necessary, to clarify any possible misuse of your personal data.

No data is passed on to third parties in connection with the data processing for sending newsletters. The data is used exclusively for sending the newsletter.

The newsletter is sent on the basis of the user's registration on the website.

The legal basis for the processing of data after registration for the newsletter by the user is Art. 6 para. 1 lit. a GDPR if the user has given consent.

The purpose of collecting the user's email address is to send the newsletter. The newsletter is sent on the basis of the user's registration on the website. The collection of other personal data as part of the registration process serves to prevent misuse of the services or the e-mail address used.

The data is deleted as soon as it is no longer required to fulfil the purpose for which it was collected. The user's e-mail address is therefore stored for as long as the subscription to the newsletter is active. The other personal data collected during the registration process is generally deleted after a period of seven days.

The subscription to the newsletter can be cancelled by the user concerned at any time. For this purpose, there is a corresponding link in every newsletter. This also makes it possible to revoke consent to the storage of personal data collected during the registration process.

We have integrated YouTube videos into our online offering, which are stored at https://www.youtube.com and can be played directly from our website. These are all integrated in "extended data protection mode" via YouTube noocokie, i.e. no data about you as a user is transferred to YouTube if you do not play the videos. Only when you play the videos will the data mentioned in paragraph 2 be transmitted. We have no influence on this data transfer.

When you visit the website, YouTube receives the information that you have accessed the corresponding subpage of our website. In addition, the data mentioned under IV of this declaration is transmitted. This occurs regardless of whether YouTube provides a user account through which you are logged in or whether no user account exists. If you are logged in to Google, your data will be assigned directly to your account. If you do not wish your data to be associated with your YouTube profile, you must log out before activating the button. YouTube stores your data as usage profiles and uses them for the purposes of advertising, market research and/or customising its website. Such an evaluation is carried out in particular (even for users who are not logged in) to provide customised 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 YouTube to exercise this right.

Further information on the purpose and scope of data collection and its processing by YouTube can be found in the privacy policy. There you will also find further information on your rights and setting options to protect your privacy: https://policies.google.com/privacy.

By playing the YouTube video, you also consent to Google processing your personal data in the USA in accordance with Art. 49 para. 1 sentence 1 lit. a GDPR. The USA is considered by the European Court of Justice to be a country with an inadequate level of data protection according to EU standards. In particular, there is a risk that your data may be processed by US authorities for monitoring and surveillance purposes, possibly without the possibility of legal recourse. If you do not play the YouTube videos, the transfer described above will not take place.

We maintain publicly accessible profiles on social networks. The individual social networks we use are listed below.

Social networks such as Facebook, Twitter etc. can generally analyse your user behaviour comprehensively when you visit their website or a website with integrated social media content (e.g. Like buttons or advertising banners). Visiting our social media presences triggers numerous data protection-relevant processing operations.

If you are logged into your social media account and visit our social media presence, the operator of the social media portal can assign this visit to your user account. However, your personal data may also be collected if you are not logged in or do not have an account with the respective social media portal. In this case, this data collection takes place, for example, via cookies that are stored on your end device or by recording your IP address.

With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, interest-based advertising can be displayed to you inside and outside the respective social media presence. If you have an account with the respective social network, the interest-based advertising can be displayed on all devices on which you are logged in or were logged in.

Please also note that we cannot track all processing operations on the social media portals. Depending on the provider, further processing operations may therefore be carried out by the operators of the social media portals. For details, please refer to the terms of use and data protection provisions of the respective social media portals.

Our social media presence is intended to ensure the widest possible presence on the Internet. This is a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR. The analysis processes initiated by the social networks may be based on different legal bases, which must be specified by the operators of the social networks (e.g. consent within the meaning of Art. 6 para. 1 lit. a GDPR).

The data collected directly by us via the social media presence will be deleted from our systems as soon as the purpose for its storage no longer applies, you request us to delete it, revoke your consent to storage or the purpose for data storage no longer applies. Stored cookies remain on your end device until you delete them. Mandatory statutory provisions - in particular retention periods - remain unaffected.

If you visit one of our social media sites (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. You can assert your rights (information, correction, deletion, restriction of processing, data portability and complaint) both against us and against the operator of the respective social media portal (e.g. against Facebook).

Please note that, despite our joint responsibility with the social media portal operators, we do not have full control over the data processing operations of the social media portals. Our options are largely determined by the company policy of the respective provider.
