Privacy policy

The following notes provide a simple overview of what happens to your personal data when you visit our website. Personal data is any data that can be used to identify you personally.

Data transmission on the Internet 

Already when you use this (or another) website, various personal data are 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 point out that data transmission over the internet (eg communication by e-mail) may have security gaps. A complete protection of the data against access by third parties is not possible.

Who is responsible for the data collection on this website?

Data processing on this website is carried out by the website operator.

The responsible party for data processing on this website is:

Dr. Vieweg Beratung

Tel 0172 2 918 918

The controller is the natural or legal person who alone or jointly with others determines the purposes and means of the processing of personal data (e.g. names, e-mail addresses or similar).

How do we collect your data?

You transmit your data to us when you send us an email. These data are stored by us only to answer your request. They will not be stored permanently or passed on.

Some data is collected automatically when visiting the website. This is mainly technical data (e.g. internet browser, operating system or time of page view). The collection of this data takes place automatically as soon as you enter our website.

What do we use your data for?

This data is collected to ensure error-free provision of the website.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.

On this site reCAPTCHA v3 is implemented and their use of reCAPTCHA v3 is subject to the Google Privacy Policy and Terms of Use.

You have the right to receive information about the origin, recipient and purpose of your stored personal data free of charge at any time.

For this purpose, as well as for further questions on the subject of data protection, you can contact us at any time at the address given in the imprint.

Furthermore, you have the right to lodge a complaint with the competent supervisory authority.

Revocation of your consent to data processing

Many data processing operations are only possible with your express consent. You can revoke an already given consent at any time. For this purpose, an informal communication by e-mail to us is sufficient. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right of appeal to the competent supervisory authority

In the event of violations of data protection law, the person concerned has the right to lodge a complaint with the competent supervisory authority. The competent supervisory authority for data protection issues is the state data protection commissioner of the federal state in which our company is based. A list of the data protection officers and their contact details can be found in the following link:

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 insofar as it is technically feasible.

Information, blocking, deletion

Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipient and the purpose of data processing and, if applicable, a right to correction, blocking or deletion of this data.

For this purpose, as well as for further questions on the subject of personal data, you can contact us at any time at the address given in the imprint.

Objection to advertising e-mails

The use of contact data published within the framework of the imprint obligation to send advertising and information materials not expressly requested is hereby prohibited. The operators of the pages expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, such as spam e-mails.
