Data protection and the protection of your personal data in particular are matters of great importance to us, and we would therefore like to provide you with the following information on the subject.

What must be observed in connection with the links to other websites on our website?

Reference is made on to other websites (e.g. The respective operators and their data protection officers are solely responsible for the data protection principles or the content of the linked sites.

What security does our website offer?

The technical and organizational security measures we use serve the purpose of protecting the data that you voluntarily provide us against unconscious or intentional manipulation, loss, destruction or access by unauthorized persons. Trei Real Estate GmbH (Trei) is constantly developing and improving security measures in line with technological developments.

How is your personal data processed (cookies)?

When you visit our website, no personal data is collected from you. Specific data is evaluated and stored on our web server each time you visit our website, but only for statistical surveys and to guarantee the security and stability of the system.

For technical reasons, your Internet browser automatically transmits data to our web server when you access our website. This includes the date and time of access, the URL of the referring website, accessed files, amount of data sent, browser type and version, operating system and your IP address. This data is stored separately from other data that you enter when using our website. It is not possible for us to assign this data to a specific person.

So-called 'cookies' are used for this purpose. A cookie is information that a web server sends to a browser, which the browser in turn sends back to the same web server when it later accesses it (so-called "browser or session cookie"). Cookies make it possible to store information between website visits and they allow a web server to recognize the visitor's browser and thus the visitor himself, or to remain recognised throughout a session. The cookies we use are so-called "session cookies". They are automatically deleted at the end of your visit.

A cookie can only contain information that the website provider itself sends to the user; the user's private data cannot be read. Please also note that cookies can only be retrieved by the creator of the cookies. This means that no other online providers can read these cookies. You can prevent or administer the use of cookies using the appropriate settings in your browser (depending on the manufacturer).

Trei will neither sell your personal data to third parties nor market it in any other way. All personal data is collected, processed and used in accordance with the applicable data protection regulations.

Use of Google Analytics

This website uses Google Analytics, an advertising analysis service of Google Inc. ("Google"). Google Analytics uses so-called "cookies", i.e. text files that are stored on your computer and enable the analysis of your use of the website. The information generated by the cookie about the use of this website is usually transferred to a Google server in the USA and stored there. However, if IP anonymization is activated on this website, Google will beforehand abbreviate your IP address within member states of the European Union or in other states party to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and abbreviated there. On behalf of the operator of this website, Google will use this information to evaluate the use of the website, compile reports on the website activities and to provide the website operator with further services associated with the use of the website and the Internet. The IP address transmitted by your browser in the context of Google Analytics is not merged with other Google data. You may reject the use of cookies by selecting the appropriate settings on your browser. However, please note that if you do this you may not be able to use the full functionality of this website.

For more information, please visit or We would like to point out that the code "anonymizeIp" has been added to Google Analytics on this website to ensure anonymous collection of IP addresses.

Use of Google AdWords

For our online offering we use the Google service "Google AdWords", and in this context the so-called "Google Conversion Tracking". "Google Conversion Tracking" sets a cookie for conversion tracking when you click on an AdWords ad; the relevant cookies for "Google Conversion Tracking" are only valid for a limited time. If you select certain pages of our online offering, Google and we can recognise on the basis of the abovementioned cookie that you have clicked on an appropriate advertisement and have been forwarded to our online offering. The information collected using cookies is used to generate so-called conversion statistics; in particular, it is used to track the total number of users who have clicked on a particular ad and have been redirected to a page with a conversion tracking tag. The conversion statistics do not contain any information that personally identifies website users.

If you do not wish to participate in Google Conversion Tracking, you have the option to object to this use. To do this, you can simply deactivate the corresponding the Google Conversion Tracking cookie in your Internet browser. If you do this the conversion tracking statistics will not be recorded. The following website provides additional information about the Google data protection regulations: (see also "Visiting the websites & cookies").

Use of Google Maps

This website uses the Google Maps service. It is provided by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. The service enables us to display interactive maps directly on our website and lets you use the map function at your convenience. It is integrated into our website via a Java Script API.

Use of Google Maps, and thus the processing of personal data by Google Maps, is not possible unless you have consented to it through the cookie settings on this page (“Marketing” category). The lawful basis for this processing of personal data is your consent pursuant to Art. 6, Sec. 1, Sent. 1, Lit. a, GDPR, or (in case the data are transmitted to the United States) pursuant to Art. 49, Sec. 1, Lit. a, GDPR. You may revoke your consent with effect to the future via the same cookie settings at any time.

As a result of using Google Maps, Google will receive information that the corresponding (sub)page of our website was called up while also receiving the associated IP address. This will happen regardless of whether Google provides a user account through which you are logged in or whether no such user account exists. If you are signed into a Google service, your data will (probably) be directly associated with your account. If you do not wish to be associated with your profile on Google, you should log out of your Google account before clicking the button. Google stores the data collected about you in the form of a user profile and uses it for advertising purposes, market research and/or the need-based design of its websites. The purpose of such an analysis is specifically to generate customised advertising (even for users not logged in). You have a right to object to the creation of such a user profile, but you will have to contact Google directly to exercise that right.

The aforesaid personal data will be transferred to the United States during the use of Google Maps. Please note that the United States are classified as a so-called third country under current data protection legislation, and are subject to different statutory data protection regulations, so that the legally required level of data protection may be lower than that in the European Union. In addition to Google, government agencies may also gain access to this data under US law if certain legal conditions are met. This is regrettably not subject to our influence.

For more information on the purpose and scope of the collection of data and their processing by the provider of Google Maps, please see the provider’s data protection statements. If you do, Google will also provide more details about your rights and privacy settings (third-party link):
