How secure is our website?

The technical and organisational security measures used by us serve the purpose of protecting the data you make available to us at your discretion against inadvertent or wilful manipulation, loss, destruction or access by unauthorised persons. Trei Real Estate GmbH (Trei) continuously develops and upgrades its security measures in sync with the latest technological advances.

How are your personal data processed (“cookies”)?

Personal data about you will principally not be collected when you visit our website. However, certain data are evaluated and stored on our web server each time you visit our website, if only for statistical purposes and to guarantee the security and stability of our system.

For technical reasons, your internet browser automatically transmits data to our web server when you access our website. Such data includes the date and time of your access, the URL of the referring website, the file accessed, the quantity of data sent, your browser type and version, your operating system and your IP address. These data are stored separately from other data that you enter while using our website. There is no way for us to associate this data with any specific person.

To this end, we use so-called “cookies.” A cookie is information that a web server sends to a browser, which the browser in turn sends back when it accesses the same web server later on (this is known as a “browser cookie” or “session cookie”). Cookies make it possible to save information between web page requests, and allow a web server to recognise a given visitor’s browser and thus the visitor him- or herself or to remain recognised through the end of a session, as the case may be. The cookies used by our website are so-called “session cookies.” They are automatically deleted at the end of your visit.

A cookie can only contain information that the web site provider itself sends to the user; it cannot be used to read the user’s private data. Please also note that the cookie contents can only be retrieved by the entity that created the cookie. In other words, no other online provider is capable of reading such cookies. You can disable or manage the use of cookies via the appropriate settings in your browser (depending on the vendor).

Trei will neither sell your personal data to any third party nor market them in any other way. The collection, processing and use of all personal data submitted to us is carried out in accordance with applicable data protection regulations.

Google Analytics uses “cookies,” i.e. text files placed on your computer, to help the website analyse how users use the site. The information generated by the cookie about your use of the website will generally be transmitted to and stored by Google on servers in the United States. In the event that IP anonymisation is enabled, Google will truncate your IP address in advance within any member state of the European Union or within any other member state of the Treaty on the European Economic Area. Only in exceptional situations will your full IP address be transmitted to a Google server in the US and truncated there. On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for the website operator and providing other services relating to website activity and internet usage.

Use of Google Ad Words 

Our online offer uses the Google service “Google AdWords” as well as the so-called “Google Conversion Tracking” in the same context. “Google Conversion Tracking” installs a conversion tracking cookie when you click on an AdWords ad; these “Google Conversion Tracking” cookies expire after a limited period of time. If you select certain pages from our online service, Google and we may recognise, based on the aforementioned cookie, that you clicked on a corresponding advertisement and were redirected to our online service. The purpose of the information collected through the use of cookies is to compile so-called conversion statistics; in particular, it makes it possible to track the total number of users who clicked on a given advertisement and were redirected to a page via a conversion tracking tag. The conversion statistics contain no information that would make it possible to personally identify website users. 

If you do not wish to participate in Google Conversion Tracking, you have the possibility to opt out of this use. To do so, you can simply disable the relevant Google Conversion Tracking cookie in your Internet browser. After that, you will no longer be included in the conversion tracking statistics.
