3.1 Visiting our website (service and IT security)

When you visit our websites, we store certain information about the browser and operating system you are using, the date and time of your visit, the access status (e.g. whether you were able to access a website or received an error message), the use of website functions, the search terms you may have entered, the frequency with which you access individual websites, the name of files accessed, the amount of data transferred, the website from which you accessed our websites and the website you visit from our websites, whether by clicking on links on our websites or by entering a domain directly in the input field of the same tab (or window) of your browser in which you opened our websites. We also store your IP address and the name of your Internet service provider for a period of seven days for security reasons, in particular to prevent and detect attacks on our websites or attempts at fraud.

We process the aforementioned personal data based on Art. 6 (1) f) GDPR due to our legitimate interest in providing you with information about our services on our websites and ensuring IT security for you when you visit our websites.

Our cooperation partners have no influence on the type and scope of data processing on this website and no data is passed on to our cooperation partners.


3.2 Requests and service

If you have any questions about methane, you can contact us by e-mail or telephone. You will find our contact details at the bottom of the homepage. We will process your personal data depending on the subject of your inquiry. We may also use personal data that has been stored in our systems as part of other data processing (e.g. data relating to previous inquiries).

Depending on the request, the data is processed for the purpose of initiating, executing or, if applicable, processing the contract with you on the basis of Art. 6 (1) b) GDPR, to fulfill our legal obligations towards you on the basis of Art. 6 (1) c) GDPR and/or due to our legitimate interest in answering your request on the basis of Art. 6 (1) f) GDPR.

If you contact one of these contact persons, the respective organization you contact will process your data independently as the controller within the meaning of Art. 4 No. 7 GDPR.


3.3 Use of cookies and tracking technology

Cookies are stored on your computer when you use our website. Cookies are small text files that are assigned to the browser you are using and stored on your hard disk and through which certain information flows to the site that sets the cookie. They also contain personal data. Cookies cannot execute programs or transfer viruses to your computer. They are used to make the website more user-friendly and effective overall.

By default, this website only uses necessary cookies and no tracking technologies. We therefore do not use active consent management.

Cookies may only be set and data sent to third-party providers when external content is accessed. Such external content is blocked by a content blocker and the content can only be accessed with prior consent.

You can make the basic settings for the categories of cookies that are absolutely necessary for the operation of the website (Essential) and for the categories of cookies for which your consent is required (Statistics, External media) in the Consent Manager. You can also make changes in your browser settings.

You can withdraw your consent at any time by clicking on “Privacy Settings” in the bottom right-hand corner of the website and calling up the Consent Manager.

Legal basis for our use of cookies

The legal basis on which we process your personal data with the help of cookies depends on whether we ask for your consent. If we ask for your consent and you give it, the legal basis for processing your data is the consent given in accordance with Art. 6 (1) a) GDPR. In the case of technically necessary cookies, the legal basis for storing information on end devices and retrieving information from end devices is Section 25 (2) no. 2 of the GDPR. Consent is not required in these cases.

Use of cookies on the basis of your consent

As this website only sets necessary cookies by default, we do not use active consent management. To load content (e.g. YouTube videos) for which cookies requiring consent are stored, you must first give your consent. The selection you make is stored in your browser via a cookie for a maximum period of 24 months or until it is deleted. You can use your browser settings to refuse the acceptance of cookies in principle or for individual cookies. If you do not want us to recognize your end device, please set your Internet browser so that it deletes cookies from your device, blocks them or warns you before a cookie is stored. Please refer to the instructions for the browser you are using. Please note that certain functions of our website may no longer work or may no longer work properly without cookies.

You can revoke your consent at any time by clicking on the “Privacy Settings” link at the bottom right of the website to open the consent manager and adjust the settings there accordingly.

Below you will find an overview of the cookies that we use on the basis of your consent given via the cookie settings. You will also find an opt-out option for each explanation of the use. These are cookies for recording the usage behavior of our website, i.e. for web analysis (also: range measurement) and cookies that are used for advertising purposes/online marketing. The use of tracking cookies enables us to recognize users when they access our website again and thus assign usage processes to an internally assigned code number (pseudonym). This allows us to record and analyze repeated visits to our website.

Unless otherwise stated, we ask you to assume that cookies used are stored for a maximum period of 24 months.

3.3.2 Statistics / Analysis


This website uses the open-source web analysis service Matomo. Through Matomo, we are able to collect and analyze data on the use of our website-by-website visitors. This enables us to find out, for instance, when which page views occurred and from which region they came. In addition, we collect various log files (e.g. IP address, referrer, browser, and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).

The use of this analysis tool is based on Art. 6(1)(f) GDPR. The website operator has a legitimate interest in the analysis of user patterns, in order to optimize the operator’s web offerings and advertising. If appropriate consent has been obtained, the processing is carried out exclusively on the basis of Art. 6(1)(a) GDPR and §25 (1) TTDSG, insofar the consent includes the storage of cookies or the access to information in the user’s end device (e.g., device fingerprinting) within the meaning of the TTDSG. This consent can be revoked at any time.

You may choose to prevent this website from aggregating and analyzing the actions you take here. Doing so will protect your privacy, but will also prevent the owner from learning from your actions and creating a better experience for you and other users.

IP anonymization

For analysis with Matomo we use IP anonymization. Your IP address is shortened before the analysis, so that it is no longer clearly assignable to you.

Analysis without cookies

We have configured Matomo in such a way that Matomo will not store cookies in your browser.


We host Matomo exclusively on our own servers so that all analysis data remains with us and is not passed on.
