2. General information and mandatory information

Data protection

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.


When you use this website, various personal data is collected. Personal data is data with which you can be personally identified. This privacy policy explains what data we collect and what we use it for. It also explains how and for what purpose this is done.


We would like to point out that data transmission over the Internet (e.g., when communicating by email) can have security gaps. Complete protection of data against access by third parties is not possible.

Information about the responsible body

The responsible body for data processing on this website is:


DataGAP GmbH
Bessemerstr. 82, 10th floor south
12103 Berlin

Email: datenschutz@butterling-immobilien.de



The responsible body is the natural or legal person who, alone or jointly with others, decides on the purposes and means of processing personal data (e.g., names, email addresses, etc.).

Revocation of your consent to data processing

Many data processing operations are only possible with your express consent. You can revoke consent you have already given at any time. To do so, simply send us an informal email. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right to object to data collection in special cases and to direct marketing (Art. 21 GDPR)

If data processing is based on Art. 6 para. 1 lit. e or f GDPR, you have the right to object to the processing of your personal data at any time for reasons arising from your particular situation; this also applies to profiling based on these provisions. The respective legal basis on which processing is based can be found in this privacy policy. If you object, we will no longer process your personal data unless we can demonstrate compelling legitimate grounds for the processing that override your interests, rights, and freedoms, or the processing serves to assert, exercise, or defend legal claims (objection pursuant to Art. 21 (1) GDPR).

If your personal data is processed for direct marketing purposes, you have the right to object at any time to the processing of personal data concerning you for such marketing purposes; this also applies to profiling insofar as it is related to such direct marketing. If you object, your personal data will no longer be used for direct marketing purposes (objection pursuant to Art. 21 (2) GDPR).
Right to lodge a complaint with the competent supervisory authority

In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the Member State of their habitual residence, their place of work, or the place of the alleged violation. The right to lodge a complaint exists without prejudice to other administrative or judicial remedies.

Right to data portability

You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done if it is technically feasible.
SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the site operator. You can recognize an encrypted connection by the fact that the address line of the browser changes from "http://" to "https://" and by the lock symbol in your browser line. If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Information, blocking, deletion, and correction

Within the framework of the applicable legal provisions, you have the right to receive information free of charge at any time about your stored personal data, its origin and recipients, and the purpose of data processing, and, if applicable, a right to correction, blocking, or deletion of this data. You can contact us at any time at the address given in the legal notice if you have any further questions on the subject of personal data.

Right to restriction of processing

You have the right to request the restriction of the processing of your personal data. To do so, you can contact us at any time at the address given in the legal notice.

The right to restriction of processing applies in the following cases:

• If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.
  
  
• If the processing of your personal data was/is unlawful, you can request the restriction of data processing instead of deletion.
  
  
• If we no longer need your personal data, but you need it to exercise, defend, or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of its deletion.
  
  
• If you have lodged an objection pursuant to Art. 21 (1) GDPR, a balance must be struck between your interests and ours. As long as it is not yet clear whose interests prevail, you have the right to request the restriction of the processing of your personal data.
  
  
• If you have restricted the processing of your personal data, this data may—apart from its storage—only be processed with your consent or for the assertion, exercise, or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the European Union or a Member State.

Objection to advertising emails

We hereby object to the use of contact data published within the scope of the imprint obligation for sending unsolicited advertising and information materials. The operators of the pages expressly reserve the right to take legal action in the event of unsolicited sending of advertising information, for example through spam emails.
3. Data collection on our website

Cookies

Some of the Internet pages use so-called cookies. Cookies do not harm your computer and do not contain viruses. Cookies serve to make our offer 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 so-called "session cookies." They are automatically deleted at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognize your browser the next time you visit.

You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when you close your browser. If you deactivate cookies, the functionality of this website may be restricted.

Cookies that are necessary for the electronic communication process or for the provision of certain functions you have requested (e.g., shopping cart function) are stored on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in storing cookies for the technically error-free and optimized provision of its services. If other cookies (e.g., cookies for analyzing your surfing behavior) are stored, these are treated separately in this privacy policy.

Server log files

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

• Browser type and browser version
• Operating system used
• Referrer URL
• Host name of the accessing computer
• Time of the server request
• IP address

This data is not merged with other data sources.

This data is collected on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimization of its website—for this purpose, the server log files must be collected.

Contact form

If you send us inquiries via the contact form, your details from the inquiry form, including the contact details you provided there, will be stored by us for the purpose of processing the inquiry and in case of follow-up questions. We will not pass on this data without your consent.

The data entered in the contact form is therefore processed exclusively on the basis of your consent (Art. 6 para. 1 lit. a GDPR). You can revoke this consent at any time. To do so, simply send us an informal email. The legality of the data processing operations carried out until the revocation remains unaffected by the revocation.

The data you enter in the contact form will remain with us until you request us to delete it, revoke your consent to its storage, or the purpose for data storage no longer applies (e.g., after your request has been processed). Mandatory legal provisions—in particular retention periods—remain unaffected.

Processing of data (customer and contract data)

We collect, process, and use personal data only to the extent necessary for the establishment, content, or modification of the legal relationship (inventory data). This is done on the basis of Art. 6 (1) lit. b GDPR, which permits the processing of data for the fulfillment of a contract or pre-contractual measures. We collect, process, and use personal data relating to the use of our website (usage data) only to the extent necessary to enable the user to use the service or to bill for it.

The customer data collected will be deleted after completion of the order or termination of the business relationship. Statutory retention periods remain unaffected.

Data transfer upon conclusion of a contract for services and digital content

We only transfer personal data to third parties if this is necessary for the execution of the contract, for example to the credit institution responsible for payment processing.

No further transfer of data takes place, or only if you have expressly consented to the transfer. Your data will not be passed on to third parties without your express consent, for example for advertising purposes.
The basis for data processing is Art. 6 (1) (b) GDPR, which permits the processing of data for the performance of a contract or pre-contractual measures.

YouTube with enhanced data protection

Our website uses plugins from the YouTube website. The operator of the pages is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA.

We use YouTube in extended data protection mode. According to YouTube, this mode means that YouTube does not store any information about visitors to this website before they watch the video. However, the extended data protection mode does not necessarily exclude the transfer of data to YouTube partners. YouTube establishes a connection to the Google DoubleClick network regardless of whether you watch a video. As soon as you start a YouTube video on our website, a connection to the YouTube servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, you enable YouTube to assign your surfing behavior directly to your personal profile. You can prevent this by logging out of your YouTube account. Furthermore, YouTube may store various cookies on your device after you start a video. With the help of these cookies, YouTube can obtain information about visitors to our website. This information is used, among other things, to collect video statistics, improve user-friendliness, and prevent fraud attempts. The cookies remain on your device until you delete them. After starting a YouTube video, further data processing operations may be triggered over which we have no control.

The use of YouTube is in the interest of an appealing presentation of our online offerings. This constitutes a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR.

Further information about data protection at YouTube can be found in their privacy policy at: https://policies.google.com/privacy?hl=de.

Vimeo also obtains your IP address. This also applies if you are not logged in to Vimeo or do not have an account with Vimeo. The information collected by Vimeo is transmitted to the Vimeo server in the USA.

If you are logged into your Vimeo account, you enable Vimeo to assign your surfing behavior directly to your personal profile. You can prevent this by logging out of your Vimeo account.

The use of Google Web Fonts is in the interest of a uniform and appealing presentation of our online offerings. This constitutes a legitimate interest within the meaning of Art. 6 (1) lit. f GDPR.

If your browser does not support web fonts, a standard font from your computer will be used.
