Data storage

In connection with your access to this website, we store and process your data (e.g. IP address, date, time and pages viewed) only during the communication process. Once the communication process ends, your IP address will be anonymised. The anonymised data will be analysed for statistical purposes.

In addition, personal data (e.g. your name, e-mail address, etc.) will not be transferred unless you provide us with such information expressly and knowingly for certain purposes. Your data will only be processed, stored and transferred to the extent required for the relevant purpose or in accordance with your consent.

This means personal data will be collected if you provide them to us voluntarily within the framework of your activities, e.g. by sending a request via our contact form and/or by sending your registration for a user account.

Collection of general data and information

The DIENES Werke website collects some general data and information every time the website is accessed by a data subject or by an automated system. Such general data and information are stored in the server logfiles. The following data may be collected: (1) browser type and version, (2) operating system used for the access to our website, (3) the website from which a system accesses our website (so-called referrer), (4) the individual pages a system accesses on our website, (5) date and time of access to our website, (6) the internet protocol address (IP address), (7) the internet service provider of the accessing system and (8) other similar data and information for danger prevention in case of attacks on our IT systems.

Such information is required in order to (1) correctly deliver the contents of our website, (2) to optimise the contents of and the marketing activities for our website, (3) to guarantee the uninterrupted functionality of our IT systems and of our website technology and (4) to provide the required information to prosecuting authorities in case of a cyber-attack. Such data and information will be collected in a pseudonymised form and analysed by DIENES Werke for statistical purposes and in order to improve data protection and data security in our company to be able to guarantee an optimised level of protection for the personal data processed by us. The pseudonymised data contained in the server logfiles will be stored separately from all the personal data provided by a data subject.

If you send us an e-mail, we will store your data. If you provide your personal or business data (e-mail addresses, names, addresses), you shall be deemed to have provided such data on a strictly voluntary basis.

Links to third-party websites

This website contains links to third-party websites. The controller of this website has no influence on the contents and data collection policies of such third-party websites. Therefore, the controller does not assume any liability for the contents and services provided on such third-party websites.

IP addresses – additional information

On this website, we do not store full IP addresses of pure visitors and/or such IP addresses shall be deleted immediately after the visitor leaves the website (exceptions see below). On webserver level, instead of the user’s actual IP address, the IP address "" is stored in the logfile (access log and error log). Therefore, no personal reference can be established.

Cookies – additional information

This website uses cookies. Cookies are small text files which your browser stores on your end-device as a file.

DIENES Werke’s websites use cookies. Cookies are text files which are stored on a computer system via an internet browser.

Numerous websites and servers use cookies. Many cookies contain a so-called cookie-ID. A cookie-ID is a unique identification number of the cookie. It is comprised of a number of characters which allocate websites and servers to the internet browser in which the cookie is stored. This helps the visited websites and servers to distinguish the data subject's individual browser from other internet browsers that contain other cookies. A certain internet browser can be recognised and identified by a unique cookie-ID.

Cookies enable DIENES Werke to provide its website users with user-friendly services which would be impossible without the use of cookies.

Cookies help us to optimise the information and contents of our websites for the user. As already mentioned, cookies help us to recognise the users of our website. The purpose thereof is to facilitate the use of our website for the users. If a website uses cookies, the user does not have to enter his/her access data during each visit on the website because this is done by the cookie provided by the website and stored on the user’s computer system.

The data subject may prevent the storage of cookies at any time by changing the relevant settings in his/her internet browser and permanently object to the storage of cookies. In addition, already set cookies can be deleted at any time via the internet browser or other software programmes. All standard internet browsers have this feature. If the data subject deactivates cookies in the internet browser, he/she may not be able to fully use all functions of our website.

Integration of social networks & third-party links

In addition to this website, we operate sites on various social media platforms which you can access by clicking on the relevant icons on our website. During your visit to one of our social media sites, your personal data may be transmitted to the operator of the social network. The operator of such social network may store the data you enter in such social medium and may also process additional information.

In addition, the operator of the social network may process the essential data of the computer system you use to visit such network, including without limitation your IP address, type of processor and browser version and plug-ins.

If you are logged into your user account with the relevant network during your visit to such network, the network will be able to allocate your visit to your account.

We cannot control the processing of customer data by the relevant social networks. For information on the purpose and scope of collection and processing of your personal data by the relevant medium and your related rights, please read the terms and conditions of the relevant controller, e.g. at:





This website uses the web analysis tool “Matomo”, a self-hosted Open Source software. The analysis tool Matomo, in the version we use, anonymises IP addresses. This means IP addresses will be shortened by the last two bytes before they are used to analyse user behaviour. Thereafter, in accordance with the prevailing opinion, the data cannot be connected to you personally anymore. Your IP address will be used in shortened form (and thus without allocation to you personally) to effect a rough geolocalisation. This means your country of origin and your access provider (internet access provider) is established and stored. The anonymised data will be stored on DIENES’ own servers and not be disclosed to third parties.

You may decide whether a unique web analysis cookie is stored on your browser in order to allow the website operator to store and analyse various statistical data. If you decide against it, please click on the following link in order to store the Matomo deactivation cookie in your browser.

The analysis tool Matomo uses a cookie which will be stored as a small text file on your end-device as a so-called persistent cookie and which will remain on your computer after your visit on our website.


Our website uses plug-ins of YouTube, a website operated by Google. The operator of the website is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA.

If you visit one of our pages where a YouTube plug-in is included, a connection to the YouTube servers will be established and the YouTube server will be informed which of our pages you visited.

If you are logged in to your YouTube account you allow YouTube to directly allocate your browsing behaviour to your personal profile. You may prevent this by logging out from your YouTube account.

The use of YouTube is in the interest of an attractive presentation of our online contents and thus based on Article 6, para. 1, lit f of the GDPR. Clicks on YouTube videos will not be stored.

For more information on the handling of user data, please go to YouTube’s data privacy notice at:  

Google Maps

This website uses the contents of Google Maps, also operated by Google, Inc. This is to directly show you interactive maps on the website, to facilitate finding the locations we state on the website and to enable you to comfortably use the map function.

This application is directly retrieved from Google’s servers, therefore the company receives your current IP. Due to your visit on the website, Google will receive the information that you accessed the relevant page of our website. We do not know if and to what extent and/or for what period of time Google stores and internally uses your IP address. The legal basis for the integration of this service is Article 6, para. 1, clause 1, lit f of the GDPR.

If you are registered with one of Google’s services, Google will be able to allocate your visit on our website to your Google account. Even if you are not registered with Google or not logged in to Google, Google may store your IP address and use it for profiling purposes. Google stores your data as user profiles and uses them for marketing, market surveys and to tailor its website to your requirements. Such analysis is made – including without limitation and irrespective of whether you are logged in or not – to show you advertising tailored to your needs and in order to inform other users of the social network of your activities on our website. You are entitled to object to the creation of such user profiles by Google.

We would like to inform you that Google may process your data outside the EU / EEA. Google also processes your personal data in the USA and is subject to the provisions of the EU-US Privacy Shield: For more information on Google’s data protection regulations, please go to

For as long as you do not delete these cookies in the browser, your user behaviour will not be analysed. You will be informed in a message if you already stored the opt-out cookie. In addition, you can re-activate web-analysis for this website if you wish.
