Notes on the use of your personal data

At CASA UNITED AG ("CASA UNITED"), we take the protection of your personal information very seriously. Our privacy and data protection policies inform you about the ways in which CASA UNITED AG processes your personal data and tell you how you can exchange this data with other members of the CASA UNITED Partner Network. You can access and print these notes at any time from any page of the CASA UNITED website by clicking the "Data Protection" link.

1. How CASA UNITED uses your data

CASA UNITED utilizes your personal data only to the extent necessary for making and structuring the contract, providing services to you or settling additional products for a fee. In so doing, we comply with the data protection and privacy laws of the Federal Republic of Germany, Switzerland and the European Union. The term, "personal data" refers to all particulars of your personal or material circumstances.

CASA UNITED does not sell your personal data, nor does it provide your data to third parties for marketing purposes without your permission. Personal data comprises the information you were required to provide to us when you registered, namely: your first and last name, your date of birth, your company name, your complete address, the industry in which you work, your picture, your email address, your telephone number, your VAT number, and your chosen password. It also includes any data provided voluntarily during registration (your cell and fax numbers, your Skype user name, your VAT number or your website address).

Usage data comprises the data that is generated when you use the CASA UNITED Partner Network. In particular, it includes information that allows us to identify you as a registered member; information on the start and end as well as the scope of your visits to the CASA UNITED website; and information on the services you used on the website. You can prevent the future use of any data voluntarily submitted at any time simply by deleting the respective details from your profile.

Your usage data is stored for payment purposes only if you select additional fee-based products and request itemized invoicing. You will be required to enter your credit card data (card holder name, credit card number and the verification code from the back of your card) on the form provided for that purpose on the CASA UNITED website only if you make use of additional fee-based products.

The data you provide is stored directly on the PCI DSS certified FinanceGate platform of PAYONE GmbH & Co. KG, Fraunhoferstrasse 2-4, 24118 Kiel, Germany. CASA UNITED itself does not store members' credit card data, nor does it have access to this data: PAYONE GmbH & Co. KG merely provides us with the credit card reference number that has been assigned to you. This enables us to process your order and identify you as a customer who has purchased additional fee-based products.

The invoices are stores in the CASA UNITED system. You can download and print them by going to “Your Payments” on the CASA UNITED homepage. The data contained in your stored itemized invoice will be deleted no later than 6 months after the itemized invoice has been made available, if you do not raise any objections and pay the outstanding during this period.

We may also utilize your data for marketing, consulting and market research purposes and for the newsletter, as well as for preparing user profiles that help us customize the services we offer. Such usage requires your approval of the declaration of consent, which is accessible from the Access Data menu on our website.

You may access your declaration of consent at any time under Access Data. You may withdraw this consent by sending a letter to CASA UNITED AG at the address provided in the Legal Notice section of our website or an appropriate email to

2. Visibility of data to other members

Your email address — which is also your user name — is only visible to those members of the CASA UNITED Partner Network that you have confirmed as desired contacts. Your password remains hidden from members of the CASA UNITED Partner Network at all times. Under no circumstances will CASA UNITED provide your password to third parties and/or make it known to them by other means.

All of your personal profile data — except your year of birth and the email address you provided (only displayed to confirmed contacts) — will be visible to members of the CASA UNITED Partner Network. Internet users who are not members of the CASA UNITED Partner Network cannot view your personal data on the CASA UNITED website.

The VAT or similar tax identification numbers you provided during registration are also displayed in your profile and visible to all members. Providing these numbers serves to further verify your status as a business person, attorney or tax consultant. As regards any other data voluntarily submitted, you may decide whether this data should be available to all members or only to your confirmed contacts. Contacts that you have confirmed will also be able to see all your other confirmed contacts.

If you refer a potential buyer to a member for a property that this member has listed, then this member will be provided with your first and last name, your complete address and your member profile. The same applies if you accept the potential buyer that another member has referred to you in your capacity as the seller of a property.

3. Establishing groups

Members of the CASA UNITED Partner Network may establish open or closed (user) groups. While open groups are available to all members, closed groups are available solely to members approved by the respective group's founder. CASA UNITED itself may also establish groups. The founder of a group can appoint any number of group members to serve as administrators. The group's founder decides whether the group will be a public group or accessible only to a certain group of people. This person also grants members read and/or write permissions within the respective group.

These details are displayed on the CASA UNITED website for the respective group but can be seen only by the group's members. All members who decide to join a particular group can read the messages that its members post if the group is marked as "public" on the CASA UNITED website.

4. Cookies

To make it as convenient as possible for our members to use the CASA UNITED Partner Network, we use a feature called “cookies”. Cookies are files that allow us to store specific data relating to you, our user, on your PC or other computing device while you are using services from CASA UNITED.

Used in this way, our cookies (specifically, “session cookies”) allow us to identify registered members while they are visiting the CASA UNITED website. Session cookies are automatically deleted at the end of your session. You will not need to log on each time using your member name and password if you selected the feature "Log me in automatically on this computer." In this case, a permanent cookie is stored on your computer until you delete it. Permanent cookies contain some of your registration data in an encoded form. However, you can log on automatically only on one computer at a time.

In general, you can block the storage of cookies, limit it to specific websites or configure your browser to notify you whenever a cookie is transmitted to your PC. You can also delete cookies from your computer's hard drive at any time. Please be advised, however, that you will be unable to use the CASA UNITED website's networking features if you disallow session cookies.

If you use additional fee-based products, which may be offered wholly or partly by third parties, then these third-party providers may also store cookies on your PC or other computing device as necessary. You can prevent such cookies from being stored on your computer by configuring your browser to block the cookies of third-party providers.

5. Log files

When you access a page on the CASA UNITED website, this access data is logged to a report file known as a server log. This access data set contains the following information:

  • the time; the status; the request that your browser sent to the server; the amount of data transmitted; the website that linked you to the requested page (“Referrer”);
  • and the product and browser version identifier (“User Agent”).

If and insofar as CASA UNITED is not subject to any statutory obligation to store certain items of data, all IP addresses you use during a visit are deleted or anonymized at the end of your session on the CASA UNITED website. Anonymizing an IP address means changing it so that particulars of personal or material circumstances can no longer be attributed to a specific or identifiable natural person. (Such attribution may be rendered entirely impossible or possible only by expending unreasonable amounts of money, labor and time.)

While CASA UNITED uses the log data recorded during your visits to the CASA UNITED website for statistical analyses, this data is anonymized first and cannot be attributed to you personally. Such analyses enable us to determine peak traffic days and times for the CASA UNITED website, as well as the extent of the data volume generated.

In addition, the logs also make it easier for us detect and fix service interruptions that can affect use of the CASA UNITED website. CASA UNITED only links data regarding page views and hits in the server log to a specific user if they have given prior permission for this kind of use. However, CASA UNITED reserves the right to utilize server log data if certain facts provide sufficient grounds to suspect that members are using the CASA UNITED Partner Network in ways that breach laws or the General Terms and Conditions of CASA UNITED. This serves to protect members and the security of member data while facilitating the smooth operation of the CASA UNITED website.

6. Google Analytics

Our websites use Google Analytics, a web analytics service provided by Google, Inc. (“Google”). Google Analytics uses “cookies”, which are text files stored on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of the website will usually be transmitted to a Google server in the United States, where it is stored. This information includes demographic data such as the age and gender of our website’s visitors and the pages visited. The reports prepared by Google Analytics for this purpose not only provide us with information about the number of visitors during a given period of time but also about who these visitors are and how their behavior varies based on attributes (e.g. male compared with female). This data is used by us to place personalized ads that is presented to our website’s users when they visit other Internet sites (“Remarketing”). For this purpose each visitor of our Internet site is compared with a specified set of criteria. If a visit meets the criteria, a cookie is generated and stored in the visitor’s browser. If a visitor whose browser contains such a cookie visits a website that is part of the Google display network, he may be shown a remarketing ad placed by us.

IP anonymization was activated on this website, so that the users’ IP address will be truncated by Google within Member States of the European Union or other parties to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be sent to a Google server in the USA and truncated there. Google will use this information on behalf of the operator of this website for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services to the website operator relating to website activity and Internet usage.

The IP address sent by your browser in connection with Google Analytics will not be merged with other data held by Google. You may prevent cookies from being stored on your computer by changing the relevant settings in your browser; however please note that if you do this you may not be able to use the full functionality of this website. Furthermore, you may prevent the data generated by the cookie and the data related to your use of the website (incl. your IP address) from being sent to and processed by Google by downloading and installing the browser plug-in available under the following link

You may prevent your date from being collected by Google Analytics by clicking on the following link. An opt-out cookie will be set, which prevents the future collection of your data when visiting this website: deactivate Google Analytics

7. Links to other social networks

Our websites also use social plug-ins (“plug-ins”) provided by the social network, operated by Facebook Inc., 1601 S. California Avenue, Palo Alto, CA 94304, USA (“Facebook”). The plug-ins are identifiable by the Facebook logo (white letter f on blue background or a thumb up icon) or the notice “Facebook Social Plugin”. You can view the design of the Facebook Social Plugins at the following URL:

In order to enable you to decide for yourself whether or not your personal data will be transmitted to Facebook when you visit our websites, we decided to implement the “2 clicks for more data protection” solution developed by heise Verlag. It ensures that the plug-ins are displayed only if you previously clicked an activation button. Your data will only be sent to Facebook if you clicked not just this button but the Facebook logo as well. Only then will your browser establish a direct connection to the Facebook servers. Facebook then directly transfers the plug-in content to your browser which embeds the latter into the website. We have no influence on the data Facebook gathers via this plug-in. You can find out here which data Facebook receives from you:

When you click Facebook’s “Like” button, Facebook is informed which pages on our website you visited. If you are logged into Facebook, your visit can be assigned to your Facebook account. If you interact with the plug-ins, for example by clicking “Like”, or entering a comment, the corresponding information is transmitted from your browser directly to Facebook and stored by it. Even if you are not logged into Facebook, there is possibility that Facebook obtains information about your ID address and stores it.

For information on the purpose and scope of data collection and processing by Facebook, as well as your rights in this respect and settings options for protecting your privacy, please visit Facebook’s privacy policy:

If you are a Facebook member and do not want Facebook to connect the data concerning your visit to our websites with your member data already stored by Facebook, please log off Facebook before entering our websites.

Alternatively, you may block Facebook Social Plugins by using add-ons for your browser, such as the “Facebook Blocker“, which you can download here:

Our websites also use the "+1 Button" provided by the social network Google Plus, operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States ("Google"). The button is identifiable by the sign "+1" on white or colored background.

If you click the Google+ button after you clicked the activation button, your browser will establish a direct connection to the Google servers. Google directly transfers the content of the ‘+1” button to your browser which embeds the latter into the website. As a result, we have no influence on the data gathered by Google via this button, but we cannot rule out that your IP address is also recorded. For information on the purpose and scope of data collection and processing by Google, as well as your rights in this respect and settings options for protecting your privacy, please visit Google’s privacy policy regarding the “+1” button:

If you are a Google Plus member and do not want Google to connect the data concerning your visit to our websites with your member data already stored by Google, please log off Google before entering our websites.

In the same way, we also use the Twitter plug-in provided by Twitter, Inc., 795 Folsom St., Suite 600, San Francisco, CA 94107, which also requires activation by clicking on a button before your personal data can be transmitted to Twitter. To obtain information about the data gathered by Twitter, on which we also have no influence, please go to

Please note that we cannot influence the use of your data by third parties to whom you have submitted your data while using the CASA UNITED website, nor the use to which this data is put.
