2.4 Cookies

Our website uses cookies. Cookies do not damage your computer and do not contain viruses. Cookies are used to make our services more user friendly, effective and secure. Cookies are small text files that are stored on your computer and saved by your browser.
Most of the cookies we use are session cookies. They are deleted automatically at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognise your browser the next time you visit us.
You can set your browser to inform you about the placement of cookies and to only allow cookies on a case-by-case basis, to exclude the acceptance of cookies in certain cases or in general, and to automatically delete cookies when the browser is closed. Disabling cookies may restrict the functionality of this website.


The page provider automatically collects and stores information in server log files, which your browser automatically transmits to us to enable us to optimise the website and display it without technical issues. This information is as follows:
– Browser type and version
– Operating system used
– Referrer URL
– Time of the server request
– IP address
The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected (e.g. once the session has ended if the data is required to provide the website).


If you contact us directly by e-mail, we shall exclusively process the data that you provide (e-mail address, surname, first name and any other personal data) for the purpose of dealing with your enquiry and your contact with us.

Please note that data transmission over the internet (e.g. e-mail communication) may be subject to security vulnerabilities. It is not possible to completely protect data against third-party access.

Your data will be deleted as soon as it is no longer required to respond to the enquiry unless legal retention obligations exist.


If you are interested in a specific property listing, you can submit an enquiry to us by means of a form. The input screen shows which personal data is transmitted to us during the enquiry. Your data may be manually recorded in the software of a third-party provider or imported via an interface. Based on the stored data, we can contact you in relation to other properties that meet the criteria established in your enquiry. Relevant property listings can be identified manually or automatically using software. We can inform you about such property listings by e-mail, letter or telephone. You are entitled to unsubscribe from this service at any time.


Our website offers users the opportunity to complete a form in order to store a property search profile. A property search profile tells us your preferences with regard to your property search. The input screen used shows which personal data is transmitted to us when storing a form.

The personal data collected in order to create a property search profile shall only be used to send you information about suitable property listings. The data transmitted may be manually recorded in the software of a third-party provider or imported via an interface. If properties are found that match the search criteria, we can notify you of these by e-mail, letter or telephone. We can also contact you at regular intervals to ask you to update your personal data in the property search profile. You can temporarily deactivate or completely delete the property search profile at any time.

You have the right to object to the processing at any time. In such an event, the conversation cannot be continued.


KLOTZ Immobilien | Bau GmbH processes personal data for marketing activities such as sending e-mails with general information about new properties if you have requested this. You can object to this at any time by sending us an e-mail or other form of written correspondence.


3.1 Google Maps

Our website uses Google Maps (API) from Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; Google Limited Ireland, ‘Google’, is responsible for Europe). Google Maps is a web service for displaying interactive maps in order to visually present geographical information. By using this service, you will be shown our location to make it easier to get to us. When you call up subpages that Google Maps is integrated into, information about your use of our website (e.g. your IP address) is transmitted to Google servers in the USA, where it is saved. This occurs regardless of whether Google provides a user account that you are logged into or there is no user account. If you are logged into Google, your data will be directly assigned to your account. If you do not wish your data to be assigned to your Google profile, you must log out of this before activating the button. Google stores your data (including for users who are not logged in) in the form of usage profiles and analyses it.

4 Social Media

Our website uses links to various social networks. These are listed below. The links are indicated by a corresponding icon. A connection to the provider is only established if you click the provider’s icon. This means that data is not automatically transmitted to social media services when you visit our website.

We do not have any influence over how the social media service providers process your data. Further information about this can be found in the applicable privacy policies, which can be accessed using the links below.
– The privacy policy outlining which information Facebook collects and how it uses this can be found at https://de-de.facebook.com/privacy/policy/
– Information about Instagram’s privacy policy is available at: https://instagram.com/about/legal/privacy/
– Further information can be found in LinkedIn’s privacy policy at: https://www.linkedin.com/legal/privacy-policy


Data shall only be stored for as long as is necessary to fulfil the relevant purpose. Unless legal retention obligations or our own overriding interests prevent us from doing so, we delete data that is no longer required.


KLOTZ Immobilien | Bau GmbH uses suitable technical and organisational security measures to protect the personal data stored against manipulation, partial or complete loss and unauthorised access by third parties. The security measures are continually improved in line with technological developments.


We may share your data with third parties if we offer a service in cooperation with a third party.

In order to combat fraud and abuse or in the event of any other suspected criminal activities, we may disclosure information to domestic and foreign law enforcement authorities and courts.

If we make any advance payments, for example in the case of a purchase on account, we reserve the right to obtain credit information from a credit agency in order to safeguard our legitimate interests in concluding a contract with solvent customers. To this end, we shall send the personal data required for a credit check to a credit agency and use the information obtained about the statistical probability of a default in payment to decide whether to establish, execute or terminate the contractual relationship. Your data shall not be transmitted to third parties for any other reason unless this is necessary to process a contract that you have concluded with us or you have expressly consented to such transmission.

We work with external service providers within the scope of fulfilling our contractual obligations and the specified purposes (in particular the publication of advertisements, the management of communities of condominium owners, data hosting or for land register documents).

We select our service providers carefully and ensure that these only process data in the manner in which we ourselves would be authorised to do so. They are also obliged not to process the data for their own purposes or to share it with unauthorised third parties.

Please note that our service providers may process your data both in the EU/EEA and in other countries that do not have an appropriate level of data protection. If we use providers in countries with a low level of security, the transmission is particularly based on Art. 17, para. 1, letter a DSG (consent) and Art. 16, para. 2, letter d DSG, with us contractually ensuring (e.g. through standard contractual clauses) that the protection of your personal data corresponds to that in Switzerland.


Within the scope of the applicable legal provisions, you have the right, at any time, to free information about the personal data stored about you, its origin and the purpose of the data processing. Where applicable, you also have the right to the rectification, restriction or erasure of this data and, if applicable, to the issuance or transmission of the data. You are furthermore entitled to object to the use of the data for marketing purposes and to revoke any previously granted consent to data processing. These rights apply providing the fulfilment of your request is not prevented by legal retention obligations or other overriding interests. You can submit your requests using the contact details listed under point 1.
