The contents of our pages were created with utmost care. However, we can not take any responsibility for accuracy, completeness and topicality of the contents.

  3. General information and mandatory information

    Data protection

    The operators of this website and its pages take the protection of your personal data very seriously. Hence, we handle your personal data as confidential information and in compliance with the statutory data protection regulations and this Data Protection Declaration.

    Whenever you use this website, a variety of personal information will be collected. Personal data comprises data that can be used to personally identify you. This Data Protection Declaration explains which data we collect as well as the purposes we use this data for. It also explains how, and for which purpose the information is collected.

    We herewith advise you that the transmission of data via the Internet (i.e. through e-mail communications) may be prone to security gaps. It is not possible to completely protect data against third-party access.

    Information about the responsible party (referred to as the “controller” in the GDPR)

    The data processing controller on this website is:

    Lethe Exterior Doors GmbH Marschgehren 14 D-28779 Bremen
    Phone: +49 421 6990690 E-Mail:

    The controller is the natural person or legal entity that single-handedly or jointly with others makes decisions as to the purposes of and resources for the processing of personal data (e.g. names, e-mail addresses, etc.).

    Storage duration

    Unless a more specific storage period has been specified in this privacy policy, your personal data will remain with us until the purpose for which it was collected no longer applies. If you assert a justified request for deletion or revoke your consent to data processing, your data will be deleted, unless we have other legally permissible reasons for storing your personal data (e.g. tax or commercial law retention periods); in the latter case, the deletion will take place after these reasons cease to apply.

    Information on data transfer to the USA

    Our website uses, in particular, tools from companies based in the USA. When these tools are active, your personal information may be transferred to the US servers of these companies. We must point out that the USA is not a safe third country within the meaning of EU data protection law. US companies are required to release personal data to security authorities without you as the data subject being able to take legal action against this. The possibility cannot therefore be excluded that US authorities (e.g. secret services) may process, evaluate and permanently store your data on US servers for monitoring purposes. We have no influence over these processing activities.

    Revocation of your consent to the processing of data

    A wide range of data processing transactions are possible only subject to your express consent. You can also revoke at any time any consent you have already given us. This shall be without prejudice to the lawfulness of any data collection that occurred prior to your revocation.

    Right to object to the collection of data in special cases; right to object to direct advertising (Art. 21 GDPR)



    Right to log a complaint with the competent supervisory agency

    In the event of violations of the GDPR, data subjects are entitled to log a complaint with a supervisory agency, in particular in the member state where they usually maintain their domicile, place of work or at the place where the alleged violation occurred. The right to log a complaint is in effect regardless of any other administrative or court proceedings available as legal recourses.

    Right to data portability

    You have the right to demand that we hand over any data we automatically process on the basis of your consent or in order to fulfil a contract be handed over to you or a third party in a commonly used, machine readable format. If you should demand the direct transfer of the data to another controller, this will be done only if it is technically feasible.

    SSL and/or TLS encryption

    For security reasons and to protect the transmission of confidential content, such as purchase orders or inquiries you submit to us as the website operator, this website uses either an SSL or a TLS encryption program. You can recognize an encrypted connection by checking whether the address line of the browser switches from “http://” to “https://” and also by the appearance of the lock icon in the browser line.

    If the SSL or TLS encryption is activated, data you transmit to us cannot be read by third parties.

    Information about, rectification and eradication of data

    Within the scope of the applicable statutory provisions, you have the right to at any time demand information about your archived personal data, their source and recipients as well as the purpose of the processing of your data. You may also have a right to have your data rectified or eradicated. If you have questions about this subject matter or any other questions about personal data, please do not hesitate to contact us at any time at the address provided in section “Information Required by Law.”

    Right to demand processing restrictions

    You have the right to demand the imposition of restrictions as far as the processing of your personal data is concerned. To do so, you may contact us at any time at the address provided in section “Information Required by Law.” The right to demand restriction of processing applies in the following cases:

    In the event that you should dispute the correctness of your data archived by us, we will usually need some time to verify this claim. During the time that this investigation is ongoing, you have the right to demand that we restrict the processing of your personal data. If the processing of your personal data was/is conducted in an unlawful manner, you have the option to demand the restriction of the processing of your data in lieu of demanding the eradication of this data. If we do not need your personal data any longer and you need it to exercise, defend or claim legal entitlements, you have the right to demand the restriction of the processing of your personal data instead of its eradication. If you have raised an objection pursuant to Art. 21 Sect. 1 GDPR, your rights and our rights will have to be weighed against each other. As long as it has not been determined whose interests prevail, you have the right to demand a restriction of the processing of your personal data.

    If you have restricted the processing of your personal data, these data – with the exception of their archiving – may be processed only subject to your consent or to claim, exercise or defend legal entitlements or to protect the rights of other natural persons or legal entities or for important public interest reasons cited by the European Union or a member state of the EU.

  4. Recording of data on this website


    Our websites and pages use what the industry refers to as “cookies.” Cookies are small text files that do not cause any damage to your device. They are either stored temporarily for the duration of a session (session cookies) or they are permanently archived on your device (permanent cookies). Session cookies are automatically deleted once you terminate your visit. Permanent cookies remain archived on your device until you actively delete them or they are automatically eradicated by your web browser.

    In some cases, it is possible that third-party cookies are stored on your device once you enter our site (thirdparty cookies). These cookies enable you or us to take advantage of certain services offered by the third party (e.g. cookies for the processing of payment services).

    Cookies have a variety of functions. Many cookies are technically essential since certain website functions would not work in the absence of the cookies (e.g. the shopping cart function or the display of videos). The purpose of other cookies may be the analysis of user patterns or the display of promotional messages.

    Cookies, which are required for the performance of electronic communication transactions (required cookies) or for the provision of certain functions you want to use (functional cookies, e.g. for the shopping cart function) or those that are necessary for the optimization of the website (e.g. cookies that provide measurable insights into the web audience), shall be stored on the basis of Art. 6 Sect. 1 lit. f GDPR, unless a different legal basis is cited. The operator of the website has a legitimate interest in the storage of cookies to ensure the technically error free and optimized provision of the operator’s services. If your consent to the storage of the cookies has been requested, the respective cookies are stored exclusively on the basis of the consent obtained (Art. 6 Sect. 1 lit. a GDPR); this consent may be revoked at any time.

    You have the option to set up your browser in such a manner that you will be notified any time cookies are placed and to permit the acceptance of cookies only in specific cases. You may also exclude the acceptance of cookies in certain cases or in general or activate the delete function for the automatic eradication of cookies when the browser closes. If cookies are deactivated, the functions of this website may be limited.

    In the event that third-party cookies are used or if cookies are used for analytical purposes, we will separately notify you in conjunction with this Data Protection Policy and, if applicable, ask for your consent.

    Server log files

    The provider of this website and its pages automatically collects and stores information in so-called server log files, which your browser communicates to us automatically. The information comprises:

    The type and version of browser used, the used operating system, Referrer URL, the hostname of the accessing computer, the time of the server inquiry, the IP address.

    This data is not merged with other data sources.

    This data is recorded on the basis of Art. 6 Sect. 1 lit. f GDPR. The operator of the website has a legitimate interest in the technically error free depiction and the optimization of the operator’s website. In order to achieve this, server log files must be recorded.

    Contact form

    If you submit inquiries to us via our contact form, the information provided in the contact form as well as any contact information provided therein will be stored by us in order to handle your inquiry and in the event that we have further questions. We will not share this information without your consent.

    The processing of these data is based on Art. 6 para. 1 lit. b GDPR, if your request is related to the execution of a contract or if it is necessary to carry out pre-contractual measures. In all other cases the processing is based on our legitimate interest in the effective processing of the requests addressed to us (Art. 6 Para. 1 lit. f GDPR) or on your agreement (Art. 6 Para. 1 lit. a GDPR) if this has been requested.

    The information you have entered into the contact form shall remain with us until you ask us to eradicate the data, revoke your consent to the archiving of data or if the purpose for which the information is being archived no longer exists (e.g. after we have concluded our response to your inquiry). This shall be without prejudice to any mandatory legal provisions – in particular retention periods.

  5. Plug-ins and Tools

    YouTube with expanded data protection integration

    Our website embeds videos of the website YouTube. The website operator is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

    We use YouTube in the expanded data protection mode. According to YouTube, this mode ensures that YouTube does not store any information about visitors to this website before they watch the video. Nevertheless, this does not necessarily mean that the sharing of data with YouTube partners can be ruled out as a result of the expanded data protection mode. For instance, regardless of whether you are watching a video, YouTube will always establish a connection with the Google DoubleClick network.

    As soon as you start to play a YouTube video on this website, a connection to YouTube’s servers will be established. As a result, the YouTube server will be notified, which of our pages you have visited. If you are logged into your YouTube account while you visit our site, you enable YouTube to directly allocate your browsing patterns to your personal profile. You have the option to prevent this by logging out of your YouTube account.

    Furthermore, after you have started to play a video, YouTube will be able to place various cookies on your device or comparable technologies for recognition (e.g. device fingerprinting). In this way YouTube will be able to obtain information about this website’s visitors. Among other things, this information will be used to generate video statistics with the aim of improving the user friendliness of the site and to prevent attempts to commit fraud.

    Under certain circumstances, additional data processing transactions may be triggered after you have started to play a YouTube video, which are beyond our control.

    The use of YouTube is based on our interest in presenting our online content in an appealing manner. Pursuant to Art. 6 Sect. 1 lit. f GDPR, this is a legitimate interest. If a corresponding agreement has been requested, the processing takes place exclusively on the basis of Art. 6 para. 1 lit. a GDPR; the agreement can be revoked at any time.

    For more information on how YouTube handles user data, please consult the YouTube Data Privacy Policy under:

    Google Web Fonts

    To ensure that fonts used on this website are uniform, this website uses so-called Web Fonts provided by Google. When you access a page on our website, your browser will load the required web fonts into your browser cache to correctly display text and fonts.

    To do this, the browser you use will have to establish a connection with Google’s servers. As a result, Google will learn that your IP address was used to access this website. The use of Google Web Fonts is based on Art. 6 Sect. 1 lit. f GDPR.

    The website operator has a legitimate interest in a uniform presentation of the font on the operator’s website. If a respective declaration of consent has been obtained (e.g. consent to the archiving of cookies), the data will be processed exclusively on the basis of Art. 6 Sect. 1 lit. a GDPR. Any such consent may be revoked at any time.

    If your browser should not support Web Fonts, a standard font installed on your computer will be used.

    For more information on Google Web Fonts, please follow this link: and consult Google’s Data Privacy Declaration under:

Zugriffsprotokolle („Server-Logs“)

Mit jedem Zugriff auf die Funnel werden automatisch allgemeine Protokolldaten, sogenannte Server-Logs, erfasst. Diese Daten sind in der Regel Pseudonyme und erlauben daher keine Rückschlüsse auf eine natürliche Person. Ohne diese Daten wäre es technisch teilweise nicht möglich, die Inhalte der Software auszuliefern und darzustellen. Zudem ist die Verarbeitung dieser Daten aus Sicherheitsaspekten, insbesondere zur Zugriffs-, Eingabe- und Weitergabe- und Speicherkontrolle, zwingend notwendig. Darüber hinaus können die anonymen Informationen für statistische Zwecke sowie für die Optimierung des Angebots und der Technik verwendet werden. Zudem können die Log-Files bei Verdacht auf eine rechtswidrige Nutzung der Software nachträglich kontrolliert und ausgewertet werden. Die Rechtsgrundlage hierfür findet sich in § 15 Abs. 1 Telemediengesetz (TMG) sowie Art. 6. (1) f DS-GVO. Erfasst werden allgemein Daten wie der Domainname der Website, der Webbrowser und Webbrowser-Version, das Betriebssystem sowie der Zeitstempel des Zugriffs auf die Software. Die IP-Adresse des Nutzers wird nicht gespeichert. Dem Nutzer wird jedoch eine sog. Session ID zugewiesen. Der Umfang dieser Protokollierung geht nicht über den gängigen Umfang jeder anderen Webseite im Internet hinaus. Die Speicherdauer dieser Zugriffsprotokolle beträgt bis zu 7 Tage. Ein Widerspruchsrecht besteht nicht.

Erhebung von User Behavior Daten

Erfasst werden allgemein Daten wie der Domainname der Website, der Webbrowser und Webbrowser-Version, das Betriebssystem, die Session ID des Nutzers sowie der Zeitstempel des Zugriffs auf die Software.

In den Funnel werden sogenannte Cookies eingesetzt. Dies sind kleine Textdateien, welche auf dem Gerät, mit welchem Sie auf diese Funnel zugreifen, gespeichert werden. Die eingesetzten Cookies dienen dazu, die Sicherheit beim Besuch einer Website zu gewährleisten („unbedingt erforderlich“), gewisse Funktionalitäten wie Standard-Spracheinstellungen umzusetzen („funktional“) und das Nutzungserlebnis oder die Performance auf der Webseite zu verbessern („Performance“). Innerhalb der Funnel kommen unbedingt erforderliche, funktionale und Performance Cookies zum Einsatz, insbesondere zur Umsetzung gewisser Voreinstellungen wie bspw. die Sprache, zur Speicherung von gegebenen Antworten auch bei schlechter Internetverbindung oder zur Analyse der Performance eines Funnel und des genutzten Kanal, über den ein Nutzer auf diese Funnel gelangt ist. Die Nutzung von Cookies ist für die Erbringung unserer Dienstleistungen und damit für die Erfüllung des Vertrags (Art. 6 (1) b) DS-GVO) zwingend erforderlich. Speicherdauer: Bis zu 1 Monat bzw. bis zur Beendigung der Browser-Session Widerspruchsrecht: Sie können über Ihre Browser-Einstellungen selbst bestimmen, ob Sie Cookies erlauben oder der Nutzung von Cookies widersprechen möchten. Bitte beachten Sie, dass eine Deaktivierung der Cookies zu einer eingeschränkten oder komplett unterbundenen Funktionalität der Funnel führen kann. Der Betreiber dieser Website hat die Möglichkeit individuell für jeden eingesetzten Funnel zu entscheiden, welche Entscheidungsmöglichkeiten zur Nutzung von Cookies dem Nutzer gegeben wird. Es ist im Rahmen der Verantwortung des Betreibers der Website, Cookies im Einklang mit den geltenden rechtlichen Beschränkungen zu nutzen. Werden von dem Betreiber der Website Erweiterungen externer Firmen innerhalb der Funnel eingesetzt, obliegt es der Verantwortung des Betreibers der Website, den Nutzer darüber aufzuklären.
