These files include:

  • the IP address of the requesting system
  • information about the type of browser and the version used
  • the operating system used

We do not merge this data with other sources of data. The temporary storage of the IP address in log files is necessary for technical reasons and for ensuring the system security, particularly for detecting misuse. Our justified interest in data processing according to Art. 6 Para 1 S. 1 lit. f DSGVO also lies in this purpose.

We delete the data as soon as they are no longer necessary for achieving the purpose for which they were collected. The IP addresses of the users are truncated or deleted by no later than after 14 days.

3.2 Other data, which we collect actively

Moreover, we also actively collect further information about the use of the website and the offers.

  • Shortened IP address (the last three digits are deleted)
  • Referrer URL (the page visited earlier)
  • Operating system
  • Date and time of visit
  • Information about page interaction (such as scroll height, clicks and mouse movements)
  • Time and duration of the page interactions
  • Sub-pages visited and the respective length of stay
  • Search queries made
  • Clicks on banners and links

We collect this information automatically by means of cookies and similar technologies, whereby selected third party technologies are also used (see here also Clause 6). To some extent, unique identifiers are stored in the cookies, so that your browser can be recognised again the next time you visit. In doing so, the identifiers do not lead to any direct inference about your identity. Detailed information about the cookies and similar technologies used by us is given in our [ Cookie Policy ].

We process the mentioned information for the following purposes:

  • for providing and improving our services
    This contains the use of information for managing and improving the technical and functional aspects of this website. We also use the information for improving our service, to design the website as more user-friendly as well as to optimise the selection of contents and functionalities.
  • for providing personalised offers
    We also use this information to customise our contents and offers to your requirements. For this purpose, we create pseudonymous usage profiles with the help of cookies. These usage profiles help us in understanding the needs and preferences of our users in a better way so that we can show you more personalised and usage-based contents and offers on this website. The pseudonymous usage profiles do not contain any information, which can lead us directly to your identity. We also do not merge the usage profiles with data, which directly identify the carriers of the pseudonyms (e.g., e-mail address), unless you explicitly give us your consent to do this (for instance, in the scope of subscribing to the newsletter according to Clause 4.2 of this data privacy policy).

We process the data only for so long as is necessary to fulfil the purposes mentioned above. Thereafter, the data is deleted.

In doing so, the pseudonymous user profiles are stored for maximum 24 months.

4 Use of special functions of the website
4.1 E-mail contact

On our website, we offer you to get in touch with us via e-mail.

The respective data from the e-mail are sent automatically to our employee responsible for processing the customer requests.

The processing of the personal data from the e-mail is meant solely for processing your request.

The personal data, which is transmitted by you when you take up contact with us, are stored for the duration of the respective conversation with you, at the most for 6 months after the end of the conversation, unless there are legally prescribed longer periods of preservation in the individual case. The conversation is considered as ended when it can be inferred from the circumstances that the respective matter has been finally clarified.

The additional personal data collected during the sending process are deleted latest by after 14 days. At all times, you have the possibility of cancelling your consent for processing the personal data. To do this, simply send a mail to: . All personal data stored while making the contact are deleted immediately in this case.

4.2 Data collection at the time of logging in and double-opt in the newsletter

When signing up for the newsletter, the personal data entered are sent from the input screen to us. In the normal case, you have to enter only your e-mail address. Sometimes, more information like surname, first name and gender are also asked. In addition, your IP address and the date and time of your request are collected automatically and saved in our server.

When you sign-up for our newsletter for the first time, you get a confirmation mail sent to the specified e-mail address. This confirmation mail contains a link, which you have to click for confirming your registration. This so-called double-opt-in method helps in verifying that the owner of the e-mail address has actually authorised the receiving of the newsletter and has agreed to the contents of the newsletter.

All sign-up processes are logged, in order to be able to demonstrate the registration process as complying with the legal requirements. This includes saving the time of registration and confirmation as well as the IP address.

When you take up contact with us, get offers or order our products or services, we process your data as defined in Article 6 (1b) DSGVO for execution of purchase orders or services based on a contract or during contract initiation exclusively for fulfilling the purposes connected with it. This mainly includes information about the address, contact persons and their contact details as well as information about your company or order-related information, for instance, about construction projects.

We do not forward your data to an uninvolved third party, unless this becomes necessary during the execution of the purchase order or the offer or else the third party is a service provider assigned by us pursuant to Article 28 DSGVO (for instance, for operating the ITK systems or for customer service). In case the data is forwarded, you will be informed about this in advance.

5 Explanation for cookies

When you visit the website for the first time, we inform you about the use of cookies and the selection options related to this. If you continue your visit of this website without changing your cookie settings, you agree to the use of cookies on this website. You can change your settings at any time. You can see the text of the cookie consent declaration at the end of the data privacy policy.

Given below is an explanation of the functioning of cookies and similar technologies as well as their use on our website.

5.1 General explanation for cookies

Cookies: Cookies are small data files, which are sent to your browser and are stored by it on the device being used, when you visit a website. Cookies can contain unique identifiers made up of a character string, using which the web pages and the servers can be assigned to the actual Internet browser, in which the cookie was saved. This enables the visited web pages to recognise the respective browser, when a website is opened again.

Cookies can store different information, such as type of browser, operating system used, language settings or other personal page settings, your use of the website, purchase order information or registration information. As a rule, cookies are not used to collect data, which identifies a person directly. However, information collected with cookies can be assigned to a natural person, if it is combined with the personal data of this person, such as an e-mail address.

This website basically uses two different types of cookies.

Session cookies are used for storing the information about your activities on our website for the duration of your visit. Session cookies are deleted as soon as you close your browser.

Permanent cookies are stored on your device for a specific period of time so that we can recognise your browser when you visit our site again during this period. Thanks to these cookies, it becomes possible to create pseudonymous usage profiles and to show you the offers particularly tailor-made for your interests.

When you open this website, cookies are set not only by this website (“First party cookies”), but also by the third party websites (“Third party cookies”). Third party cookies enable the provision of features and functions of a third party on or through our website (e.g., advertisements, interactive contents and analytics). In doing so, some third party providers also collect information via our website about the pages you have visited earlier or about the products, for which you have shown interest, in order thus to show you advertisements, which best match your interests.

Apart from this, sometimes other technologies are used, which work in the same way as cookies and store data in your browser or on your device. Although, it is not possible for you to specifically decline or deactivate these tracking technologies through your browser settings, but they normally work only together with cookies. Accordingly, deactivating the cookies in your browser also leads to a deactivation of these technologies in most of the cases.

All these technologies are hereinafter collectively referred to as “cookies”.

5.2 Types of cookies that we use on our website

First party and third party cookies are used in this website for various reasons. Given below is a comprehensive overview of the different categories of cookies used in this website and the reasons for their use:

Absolutely necessary cookies: These cookies are necessary, so that the fundamental functions of our website work properly, you can navigate on the website, move around on the website and make use of specific functions. It is mandatory for us to use necessary cookies, for instance, in order to identify uniquely registered users so that they can be recognised by the website when they visit again, or in order to make available the contact forms. These cookies are used neither for advertising purposes nor for creating a user or usage profile. They are stored for the duration of your Internet session.

Tracking cookies: We use tracking cookies, in order to settle the commissions on offers made by our business partners, with whom we cooperate. To do this, the tracking cookies document, whether and when a specific offer was clicked. If you subsequently buy something from the participating business partner, the cookie identifies you as coming from our website and we earn our commission. These cookies serve solely the purpose of a correct assignment of sales to the respective offers on our website.

Functional cookies: With the help of these cookies, the settings made by you (e.g., cookie settings) are saved for your next visit.

Performance and web analysis cookies: These cookies collect information about how you use the website e.g., which categories and sub-pages you call frequently, at what time most of the accesses are made or whether you get error messages. All information collected by these cookies is made available to us only in an aggregated form. They are meant exclusively for enhancing and improving the functioning and performance of the website. Web analysis cookies can be assigned by us or by a third party on our behalf and are saved for the duration of your Internet session.

Advertising and targeting cookies: These cookies help us in registering your surfing habits and to provide offers customised and personalised offers on this website for your interests as well as to show you the third party advertisements related to our offers according to your interest. These cookies collect, for instance, information about the offers on this website, for which you show interest. The collection and evaluation is done only pseudonymously and does not allow us to identify you. We also use these cookies for controlling the frequency, with which offers are shown to you so that you do not see the same offer again and again. Moreover, we can collect and evaluate the effectiveness of our advertisements, which we show on third party websites, for statistical and market research purposes. These cookies are mostly used by third party providers on our behalf e.g., by advertising networks or by providers of social networking sites.

5.3 Your selection options

Most of the browsers accept cookies automatically. However, you can configure your browser in such a way that no cookies are stored on your computer or a message is always shown before a new cookie is created. Each browser is a little different, therefore, please read in the Help settings of your browser, how you can manage the browser settings.

If you use different devices (e.g., Smartphone, tablet, computer, etc.), please make sure that every browser on your device conforms to the cookie settings.

Moreover, it is also possible for you to disable the receipt of all cookies via this website, which are not absolutely necessary for the function of the website, click here. In this case, we save a so-called “opt-out” cookie on your device. If you delete the “opt-out cookie” set by us, use a different browser or change the device, you must activate the opt-cookie again. Please also note that the “opt-out cookies” work only when the browser is set in such a way that use of cookies is allowed.

Some Internet browsers offer the possibility of sending “Do Not Track” or “DNT” signals. Uniform standards for “DNT” signals have not yet been developed, therefore, this website currently does not use or respond to the “DNT” signals.

Please note that completely disabling the cookies can cause that you cannot use all the functions of this website.

These third party providers can collect data about your use of this website and your interaction with its contents and functions, including the total number of visitors to this website, the referrer URL, the pages you visit, date, time and duration of your visit, frequency, banners/links clicked as well as information about the device type, browser version, language settings and geographical location (including country, city, region). The third part providers can also use cookies and register your device identification and IP address.

All information collected is transmitted directly to the server of the third party provider and is stored there. The information is made available to us only anonymously and in statistical form. We do not have any access to the data, which enables us to identify you.

Sometimes, we work together with third party providers, who are established in USA. The data transmission to the service providers in USA is done according to the principles of the so-called EU-US Privacy Shield or based on the so-called standard contractual clauses of the EU Commission. More information about this is given in the clause 7.2.

Given below is an overview and a description of the third party technologies, which can be used in this website.

6.1 Performance or web analysis tools

We use all the performance or web analysis tools only with activated IP anonymisation so that the last three digits of the IP address are deleted immediately after the data is collected and only the shortened IP address is stored on the servers of the respective third party providers.

6.1.1 Google Analytics

Google Analytics is a web analysis service of Google Inc., Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”). With the help of cookies, Google collects information about the use of this website by the users. Google uses the collected data on our behalf, in order to evaluate the use of this website, in order to generate reports about the activities on our website and to provide further services to us connected with the use of our website.

The information collected by Google about the use of this website (including the shortened IP address) are saved on servers of Google in the US. Only in exceptional cases, the complete IP address is sent directly to the Google server in the US and is shortened there. As stated by Google, the shortened IP address is not combined with other data by Google. Google deletes the user identifiers stored by Google Analytics (e.g., cookie IDs) automatically after 14 months.

More information about the conditions of use and data privacy of Google Analytics is given at: https://support.google.com/analytics/answer/6004245?hl=de .

More information about how Google handles your data is given in the data privacy regulations of Google: https://www.google.de/policies/privacy/ .

7 Forwarding of information to third parties

We forward your personal data to a third party only when this is necessary for the purpose of presenting this website or our services, because we are committed or authorised to do this contractually or legally, or you have given us your explicit consent to do this.

7.1 Forwarding to service providers

We also work together with technical service providers, who are authorised based on Art. 28 DS-GVO to provide services on our behalf and according to our instructions. These companies can be given access to your data, but only the extent that is necessary for the fulfillment of their respective tasks. Thus, for instance, we assign service providers with the task of sending our newsletter or other marketing services, with web analysis or with infrastructure and IT services.

7.2 Transmission of your data to companies outside of the EU

It can happen the service providers assigned by us are established in a third country i.e., in countries outside of the European Union (EU)/the European Economic Community (EEC). However, we work exclusively with those companies that offer an appropriate level of data privacy according to the specifications of DSGVO.

At present, we are working together with third party providers, who are established in USA. The data transmission to the service providers in USA is done according to the principles of the so-called EU-US Privacy Shield as well as based on the so-called standard contractual clauses of the EU Commission. The EU-US “Privacy Shield” is an agreement made between the European Union and the US, which is meant to ensure the adherence to European data privacy standards in the US. The standard contractual clauses of the EU Commission are a contract, in which the service providers are committed to protect the data of the users, process them conforming to the regulations given in our contract and, in particular, not to pass these on to third parties. We will be happy to provide you with a copy of these standard contractual clauses. To do this, please send us a letter as well as a stamped return envelope to the address given under Clause 9.
