(1) This website uses Google Analytics, a web analysis service of Google Inc. ("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze 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, in the event that 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 signatory states to the Agreement on the European Economic Area before this happens. Only in exceptional cases will the full IP address be transferred to a Google server in the USA and shortened 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 the website activities and to provide further services to the website operator in connection with the use of the website and the internet.

(2) The IP address transmitted by your browser within the framework of Google Analytics is not merged with other data from Google.

(3) You can prevent the storage of cookies by adjusting your browser software accordingly; however, we would like to point out that in this case you may not be able to use all functions of this website to their full extent.

addresses to be further processed in a shortened form, thus excluding the possibility of personal references. If the data collected about you contains a personal reference, this is immediately excluded and the personal data is immediately deleted.

(5) 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. For the exceptional cases in which personal data is transferred to the USA, Google has subjected itself to the EU-US Privacy Shield,

(1) Wir nutzen das Angebot von Google Adwords, um mit Hilfe von Werbemitteln (sogenannten Google Adwords) auf externen Webseiten auf unsere attraktiven Angebote aufmerksam zu machen. Wir können in Relation zu den Daten der Werbekampagnen ermitteln, wie erfolgreich die einzelnen Werbemaßnahmen sind. Wir verfolgen damit das Interesse, Ihnen Werbung anzuzeigen, die für Sie von Interesse sein kann, unsere Website für Sie interessanter zu gestalten und eine faire Berechnung von Werbekosten zu erreichen.

(2) Diese Werbemittel werden durch Google über sogenannte „Ad Server“ ausgeliefert. Dazu nutzen wir Ad Server Cookies, durch die bestimmte Parameter zur Erfolgsmessung, wie Einblendung der Anzeigen oder Klicks durch die Nutzer, gemessen werden können. Sofern Sie über eine Google-Anzeige auf unsere Website gelangen, wird von Google Adwords ein Cookie in ihrem PC gespeichert. Diese Cookies verlieren in der Regel nach 30 Tagen ihre Gültigkeit und sollen nicht dazu dienen, Sie persönlich zu identifizieren. Zu diesem Cookie werden in der Regel als Analyse-Werte die Unique Cookie-ID, Anzahl Ad Impressions pro Platzierung (Frequency), letzte Impression (relevant für Post-View-Conversions) sowie Opt-out-Informationen (Markierung, dass der Nutzer nicht mehr angesprochen werden möchte) gespeichert.

(3) Diese Cookies ermöglichen Google, Ihren Internetbrowser wiederzuerkennen. Sofern ein Nutzer bestimmte Seiten der Webseite eines Adwords-Kunden besucht und das auf seinem Computer gespeicherte Cookie noch nicht abgelaufen ist, können Google und der Kunde erkennen, dass der Nutzer auf die Anzeige geklickt hat und zu dieser Seite weitergeleitet wurde. Jedem Adwords-Kunden wird ein anderes Cookie zugeordnet. Cookies können somit nicht über die Webseiten von Adwords-Kunden nachverfolgt werden. Wir selbst erheben und verarbeiten in den genannten Werbemaßnahmen keine personenbezogenen Daten. Wir erhalten von Google lediglich statistische Auswertungen zur Verfügung gestellt. Anhand dieser Auswertungen können wir erkennen, welche der eingesetzten Werbemaßnahmen besonders effektiv sind. Weitergehende Daten aus dem Einsatz der Werbemittel erhalten wir nicht, insbesondere können wir die Nutzer nicht anhand dieser Informationen identifizieren.

(4) Aufgrund der eingesetzten Marketing-Tools baut Ihr Browser automatisch eine direkte Verbindung mit dem Server von Google auf. Wir haben keinen Einfluss auf den Umfang und die weitere Verwendung der Daten, die durch den Einsatz dieses Tools durch Google erhoben werden und informieren Sie daher entsprechend unserem Kenntnisstand: Durch die Einbindung von AdWords Conversion erhält Google die Information, dass Sie den entsprechenden Teil unseres Internetauftritts aufgerufen oder eine Anzeige von uns angeklickt haben. Sofern Sie bei einem Dienst von Google registriert sind, kann Google den Besuch Ihrem Account zuordnen. Selbst wenn Sie nicht bei Google registriert sind bzw. sich nicht eingeloggt haben, besteht die Möglichkeit, dass der Anbieter Ihre IP-Adresse in Erfahrung bringt und speichert.

(5) Sie können die Teilnahme an diesem Tracking-Verfahren auf verschiedene Weise verhindern: a) durch eine entsprechende Einstellung Ihrer Browser-Software, insbesondere führt die Unterdrückung von Drittcookies dazu, dass Sie keine Anzeigen von Drittanbietern erhalten; b) durch Deaktivierung der Cookies für Conversion-Tracking, indem Sie Ihren Browser so einstellen, dass Cookies von der Domain „“ blockiert werden,, wobei diese Einstellung gelöscht werden, wenn Sie Ihre Cookies löschen; c) durch Deaktivierung der interessenbezogenen Anzeigen der Anbieter, die Teil der Selbstregulierungs-Kampagne „About Ads“ sind, über den Link, wobei diese Einstellung gelöscht wird, wenn Sie Ihre Cookies löschen; d) durch dauerhafte Deaktivierung in Ihren Browsern Firefox, Internetex-plorer oder Google Chrome unter dem Link Wir weisen Sie darauf hin, dass Sie in diesem Fall gegebenenfalls nicht alle Funktionen dieses Angebots vollumfänglich nutzen können.

In principle, your personal data will only be passed on without your express prior consent in the following cases:
If it is necessary for the clarification of an illegal use of our services or for the prosecution
, personal data will be forwarded to the prosecution authorities as well as to injured third parties if necessary. However, this only happens if there are concrete indications of illegal or abusive behaviour. A transfer can also take place if this serves the enforcement of terms of use or other agreements. We are also legally obliged to provide information to certain public bodies on request. These are criminal prosecution authorities, authorities that pursue administrative offences for which fines have been imposed and the tax authorities.
The disclosure of such data is based on our legitimate interest in combating abuse, prosecuting criminal offences and securing, asserting and enforcing claims and that your rights and interests in the protection of your personal data do not outweigh, Art. 6 para. 1 lit. f DSGVO or due to a legal obligation under Art. 6 para. 1 lit. c DSGVO.

Furthermore, we use Amazon Web Services (hosting) and Heroku as well as AirCall and external call centre services as contract processors.


We will delete or make anonymous your personal data as soon as it is no longer required for the purposes for which it was collected or used in accordance with the preceding paragraphs. As a rule, we store your personal data for the duration of the usage or contractual relationship via the website plus a period of 14 days during which we retain backup copies after
deletion, unless this data is required for longer for legal reasons or for criminal prosecution or to secure, assert or enforce legal claims. If data must be retained for legal reasons, it will be blocked. The data is then no longer available for further use.


Collected data: We collect and process the data provided by you, such as your contact details, your name and your application documents, if you apply to us via the application form. All data that you send us is transferred in encrypted form between your browser and our server.

Purposes of data processing: Data processing serves the purpose of transferring your application to us and thus ensuring an application procedure. In exceptional cases, the data will be used to defend against legal claims on your part.

Legal basis: We process your data in order to carry out pre-contractual and contractual measures in response to your application (Article 6(1)(b) of the DS-GVO) and, where appropriate, in the interests of defending against legal claims (Article 6(1)(f) of the DS-GVO)
