Data protection

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

If you use this website, various pieces of personal data will be collected. Personal information includes any data with which you could be personally identified. This data protection statement explains what information we collect and what we use it for. It also explains how and for what purpose this is done.

Please note that data transmitted via the internet (e.g. via e-mail communication) may be subject to security breaches. Complete protection of data against access by third parties is not possible.



Notice concerning the Data Controller

The Data Controller for this website is:

 Prof. . Nikolai Hopf
 Specialist in Neurosurgery
Leibnizstrasse 40, 70193 Stuttgart

Tel.: 0711 860 555

The Data Controller is a physical or legal person who decides individually or with other persons about the goals and methods of the processing of personal data such as your name and e-mail address.



Revoking consent for the processing of your data

Many data processing operations are only possible with your express consent. You may withdraw your consent at any time. To do so, an informal message sent to us by email is sufficient. The legality of the data processing performed prior to your revocation of consent remains unaffected.




Right to object to data collection in special cases and to direct advertising

(Art. 21 GDPR)

If the data is processed on the basis of Art. 6 para. 1 (e) or (f) of the GDPR, you have the right to object at any time to the processing of your personal data 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 data protection declaration. If you lodge an objection, we will no longer process your personal data, unless we can prove compelling legitimate reasons for the processing that outweigh your interests, rights and freedoms, or where the processing serves to assert, exercise or defend a legal claim (objection on the basis of Art. 21 para. 1 of the GDPR).

Where your personal data is processed for direct marketing purposes, you have the right at any time to object to the processing of your personal data for the purpose of advertising, including profiling, to the extent it is related to such direct marketing. If you object, your personal data will no longer be used for the purposes of direct marketing (objection on the basis of Art. 21 para. 2 of the GDPR).



Right to file complaints with the regulatory authorities

In the event of infringements of the GDPR, the persons concerned shall have the right to appeal to a supervisory authority, particularly in the member state of their habitual residence, workplace or place of presumed infringement. Your right to appeal exists without prejudice to other administrative or judicial remedies.


Right to data portability

You have the right to have data which we process on the basis of your consent or in fulfilment of a contract automatically delivered to yourself or to a third party in a standard, machine-readable format. If you request the direct transfer of data to another data controller, this will only occur if it is technically feasible.



SSL and TLS encryption

This site uses SSL or TLS encryption for security reasons and for the protection of the transmission of confidential content, such as the enquiries you send to us as site operator. You can recognise an encrypted connection by the fact that the address line of the browser changes from “http://” to “https://”, and the lock symbol in your browser bar.

If SSL or TLS encryption is activated, the data you transfer to us cannot be read by third parties.



Disclosure, blocking, erasure and rectification

As permitted by law, you have the right to be provided with information free of charge at any time about any of your personal data that is stored as well as its origin, the recipient and the purpose for which it has been processed. You also have the right to have this data corrected, blocked or deleted. You can contact us for this purpose at any time, at the address given in the legal notice and for further questions regarding personal data.



Right to limitation of the data processing

You have the right to request that the processing of your personal data be restricted. You can contact us at any time at the address stated on our site notice page. The right to limit the data processing exists in the following cases:

If you dispute the accuracy of your personal data stored with us, we usually need time to verify this. During the verification period, you have the right to demand that the processing of your personal data be limited.

If the processing of your personal data has taken / is taking place unlawfully, you can demand that its processing be restricted or limited, instead of the erasure of the data.

If we no longer require your personal data, but you do need them in order to exercise, defend or assert a legal claim, you have the right to request that the processing of your personal data be restricted instead of the data being deleted.

If you have filed an objection pursuant to Article 21 Para. 1 of the GDPR, a balance must be made between your interests and ours. As long as it has not been ascertained whose interests prevail, you have the right to demand that the processing of your personal data be restricted.

Where the processing of your personal data has been restricted, such data – apart from being stored – may be processed only with your consent, or for the purpose of asserting, exercising or defending or protecting the rights of another natural or legal person, or on the grounds of an important public interest of the European Union or of a Member State.




Server log files

The website provider automatically collects and stores information in so-called “server log files”, which your browser automatically transmits to us. This includes:

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

These data will not be combined with data from other sources.

These data are collected on the basis of Art. 6 para. 1 (f) of the GDPR. The website operator has a legitimate interest in the technically correct display and optimisation of its website; for this purpose, the server log files must be stored.



Contact form

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you have provided there, will be stored by us for the purpose of processing the enquiry and in the event of follow-up enquiries. We do not pass on these data without your consent.

We will therefore process any data you enter onto the contact form only with your consent (Art. 6 para. 1 (a) of the GDPR). You may revoke your consent at any time. An informal message sent to us by email is sufficient to do this. The legality of the data processing performed prior to the revocation remains unaffected by the revocation.

We will retain the data you provide on the contact form until such time as you request its deletion, revoke your consent for its storage, or the purpose for its storage no longer applies (e.g. after fulfilling your request). The mandatory provisions of law, with particular regard to data conservation periods, remain unaffected.




Google Maps

This site uses the Google Maps map service via an API. This is operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

To use Google Maps, your IP address must be saved. This information is generally transmitted to a Google server in the US and stored there. The provider of this site has no influence on this data transfer.

The use of Google Maps is in the interest of an appealing presentation of our website and facilitates the location of the places we specify on the website. This constitutes a legitimate interest in accordance with article 6, para. (1) (f) of the GDPR.
