1. General Information

The protection of personal data is important for us. For this reason, the Anton Große-Wentrup GmbH processes personal data only in accordance with the current General Data Protection Regulation (GDPR). This privacy policy informs you about which personal data is collected by visiting this website, for what purpose it is used, to whom it may be made available and what rights you as the data subject possess (in particular Art. 12-14 GDPR).

Usually, the use of our website is possible without providing personal data. Certain data (pages retrieved, names of retrieved files, date, time) are stored on the server for statistical purposes. Information in the server log files (IP address, time of server request, browser type, browser version and operating system of the requesting computer), which are transmitted by the browser, are not subject to personal data analysis. These data can not be assigned to specific persons at any time. Like many other websites, we also use so-called "cookies". Cookies are small text files that are transferred from a website server to your hard drive. This automatically gives us certain data, such as the IP address, used internet browser, operating system, and your connection to the Internet. Cookies can not be used to launch programs or to transfer viruses to a computer. Based on the information contained in cookies, we can facilitate navigation and enable an appropriate and proper presentation of our websites. No collected data will be passed on to third parties, and no link with personal data will be established without your consent. In general, you can deactivate the use of cookies at any time in your browser settings. Please use the help functions of your internet browser to find out how to change these settings. Please note that some features of our website may not work if you have disabled the use of cookies.

As far as personal data (for example name, address, email) are collected on this website, we do this (if possible) only with the consent of the user. These data will not be disclosed to third parties without your explicit consent. Please note that data transmission (for example, when communicating by e-mail) may have security vulnerabilities. A complete protection of the data from access by third parties is not possible.

This Privacy Policy explains the nature, scope and purpose of the processing of personal data. "Personal data" means any information relating to an identified or identifiable natural person (hereinafter the "data subject"). A natural person is considered as being identifiable, if he or she is relatable and referable (directly or indirectly) on basis of an identifier such as a name, an identification number, location data, an online identifier, or one or more special characteristics expressing the physical, physiological, genetic, mental, economic, cultural or social identity of this natural person. With regard to further basic terminology, such as "processing" or"controller" we refer to the definitions in Article 4 of the General Data Protection Regulation (GDPR). The processing of personal data is based on our legitimate interest to fulfill our contractually agreed services and to optimize our online services.
