Data Protection Declaration / Notes on Data Protection

With the following notes we inform you about the purpose, type and extent of the collection, processing and use of personal data on our website. The following information relates primarily to the collection, processing, and storage of personal data by our web server. Please note that there may be additional notes that apply for registered users in our Terms of Use. Personal data is individual information about personal and factual circumstances of a certain or identifiable natural person.


Hosting services by jweiland

Within the scope of data processing on our behalf jweiland provide for us services for the hosting and presentation of the website. All data collected in the course of using this website or in forms provided for this purpose are processed on their servers within Germany. Processing on other servers only takes place within the scope explained here.



When visiting our internet pages, data is collected, processed, and used, for which a personal reference cannot always be excluded. In order for the pages to be displayed in your browser, the IP address must be identified and stored. Usually, an IP address is assigned dynamically by your provider. This address usually changes regularly, so that we cannot establish a personal reference from the IP address. With static IP addresses, however, the creation of a personal reference would be theoretically possible in individual cases.

In detail, the following data record is stored for each retrieval:

    IP address of the calling computer
    Operating system of the calling computer
    Browser version of the calling computer
    Name of the retrieved file
    Date and time of the retrieval
    Transmitted data volume
    Referring URL

The stored data is only evaluated for statistical purposes and not for the creation of a concrete personal reference. The data will also be used, if necessary, to enable the correction of errors. IP addresses are deleted after 72 hours at the latest.

Web analysis by Matomo (formerly PIWIK)

1. Scope of the processing of personal data: We use the Matomo (formerly PIWIK) open source software tool on our website to analyse the surfing behaviour of our users. The software sets a cookie on the user's computer (for cookies, see above). If individual pages of our website are called up, the following data is stored:

a. Two bytes of the IP address of the user's calling system

b. The accessed website

c. The website from which the user has reached the accessed website (referrer)

d. The subpages that are accessed from the accessed web page

e. The time spent on the website

f. The frequency of visiting the website

The software runs exclusively on the servers of our website. The personal data of the users are only stored there. The data will not be passed on to third parties.

2. Legal basis for the processing of personal data: The legal basis for the processing of users' personal data is Art. 6 para. 1 letter f of the General Data Protection Regulation (GDPR).

3. Purpose of data processing: The processing of users' personal data enables us to analyse the surfing behaviour of our users. By evaluating the data obtained, we are able to compile information on the use of the individual components of our website. This helps us to constantly improve our website and its user-friendliness (“usability”). These purposes also include our legitimate interest in processing the data in accordance with Art. 6 para. 1 lit. f of the GDPR. By rendering the IP address anonymous, the interest of the users in their protection of personal data is sufficiently taken into account.

4. Duration of storage: The data is deleted as soon as it is no longer required for our recording purposes. For our website this is the case after 12 months.

5. Possibility of objection and removal: Cookies are stored on the user's computer and transmitted by the user’s computer to our side. Therefore, you as a user also have full control over the use of cookies. By changing the settings in your internet browser, you can deactivate or restrict the transmission of cookies. Cookies that have already been stored can be deleted at any time. This can also be done automatically. If cookies are deactivated for our website, it is possible that not all functions of the website can be used to their full extent.
