If you use this website, various pieces of personal data will be collected. Personal information is any data with which you could be personally identified. This privacy policy explains what information we collect and what we use it for. It also explains how and for what purpose this happens.

By visiting our website, you are accepting the practices described in this privacy policy.

Please note that data transmitted via the internet (e.g. via email communication) may be subject to security breaches. Complete protection of your data from third-party access is not possible.


The person responsible for processing data on this website is:

KLANG:technologies GmbH
Wespienstr. 8–10
52062 Aachen

phone: +49 (0) 241 89 0301 20

The responsible party is the natural or legal person who alone or jointly with others decides on the purposes and means of processing personal data (names, email addresses, etc.).


Who is responsible for the data collection on this website?

The data collected on this website are processed by the website operator. The operator’s contact details can be found above and in the website’s required legal notice.

How do we collect your data?

Some data are collected when you provide it to us. This could be, for example, data you enter on a contact form or data you provide in communications sent to us by other means. The collection and processing of these data is necessary to provide the requested services, information etc.

Other data are collected automatically by our IT systems when you visit the website. These data are primarily technical data and usage details such as the browser and operating system you are using or information on when and from where you accessed the page, or your IP address, for example when you download software. These data are collected automatically as soon as you enter our website, regularly only with you prior consent. An exception applies in cases in which your prior consent can not be obtained for practical reasons and the data processing it permitted by law.

What is the legal basis for the collection of your data?

The processing of your data is either based on your consent – GDPR art. 6(1)(a) – or it is necessary for the performance of a contract to which you are a party or in order to take steps at your request to entering into a contract – GDPR art. 6(1)(b) -, or it is based on a legitimate interest – GDPR Art. 6(1)(f).

What do we use your data for?

Part of the data is collected to ensure the proper functioning of the website, to keep it safe and secure, to present it in the best way possible for you and your computer etc. Some data is necessary to provide services or information requested by you or to carry out obligations from a contract between you and us. Other data can be used to analyse how visitors use the site, to measure and understand the effectiveness of advertising, to administer the website and to carry out internal operations, such as data analysis, testing, research, statistical and survey purposes, etc.

Where do we store personal data and for how long?

The personal data that we collect from you or that you provide may be transferred to, and stored at, locations outside of the European Economic Area (EEA). It may also be processed by staff operating outside the EEA who work for us or one of our suppliers. These staff may be engaged in, among other things, the fulfilment of services requested by you or the provision of support services etc.

As described in this privacy policy, we may also share personal data relating to you with other company within our group or with third parties who are located overseas for business purposes and operation, support and continuity purposes, for example, when we use IT service providers or data storage services. Countries where personal data relating to you may be stored and/or processed, or where recipients of personal data relating to you may be located may have data protections laws which differ to the data protection in the your country of residence.

Some services process personal data relating to you i.e. in the USA. By consenting to the use of these services, you also consent to the processing of your data in the USA etc. in accordance with GDPR art. 49(1). The USA is considered by the European Court of Justice (ECJ) to be a country with an insufficient level of data protection according to EU standards. In particular, there is a risk that your data will be processed by US authorities for control and monitoring purposes, perhaps without the possibility of legal recourse.

By submitting your personal data, you accept that personal data relating to you may be transferred, stored or processed in this way. We will of course take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this policy.

We take all reasonably necessary steps to destroy or de-identify personal data when the information is no longer required for any purpose for which it may be used or disclosed by us and we are no longer required by law to retain the information.

How do we protect your personal data?

Unfortunately, the transmission of information via the internet is not completely secure. Although we will do our best to protect personal data relating to you, we cannot guarantee the security of such data transmitted to the Website; any transmission is at your own risk. Once we have received personal data relating to you, we use strict procedures and security features to try to prevent unauthorised access.

We take all reasonably necessary steps to destroy or de-identify personal data when the information is no longer required for any purpose for which it may be used or disclosed by us and we are no longer required by law to retain the information.

This website uses MailChimp services to distribute newsletters. This service is operated by Rocket Science Group LLC, 675 Ponce De Leon Ave NE, Suite 5000, Atlanta, GA 30308, USA.

MailChimp is a service to organize and analyze the distribution of newsletters. If you provide your data with the purpose of receiving the newsletter (such as your email address), these data will be stored by MailChimp in the USA.

Using MailChimp helps us to analyze our newsletter campaigns. When you open an email sent out via MailChimp, a file contained within the email (a so-called web beacon) will connect to the MailChimp servers located in the USA. This enables us to learn whether the newsletter mail was opened and which links were clicked. In addition, MailChimp will store technical information such as the time of receipt, IP address, type of browser and operation system. This information cannot be connected to the newsletter recipient. They are used exclusively for statistical analysis of the newsletter campaigns. The results of these analyses can be used to better adapt future newsletter to the recipients’ interests.

If you do not wish to be part of such an analysis by MailChimp, please unsubscribe from the newsletter. You can do so by following the “unsubscribe” link we provide in every newsletter. You can also unsubscribe from the newsletter directly on our website.

Your data will be processed only in accordance with your consent (GDPR art. 6(1)(a)). You may withdraw this consent at any time by unsubscribing from the newsletter. A withdrawal will not affect the lawfulness of all earlier data processing. We will store the data you disclosed in order to receive the newsletter until you unsubscribe from the newsletter and we will delete the data from our servers as well as from MailChimp servers after you unsubscribed. This does not affect data we store for other purposes (for example email address for member website). You will find more information on MailChimp’s privacy policy here:
