General notes and mandatory information


The operators of these sites 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 data protection declaration.

When you use this website, various personal data are collected. Personal data is data that can be used to personally identify you. 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 via e-mail) may have security gaps. Complete protection of data against access by third parties is not possible.

Note on the responsible body

The data controller on this website is:

Torsten Katthöfer GmbH
Sandtorkai 75
c/o Montua Partner
20457 Hamburg

Phone: +49 (40) 36801931

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

Revocation of your consent to data processing

Many data processing operations are only possible with your explicit consent. You can revoke your consent at any time. An informal message by e-mail to us is sufficient for this purpose. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right to object to the collection of data in special cases as well as to direct marketing (Art. 21 GDPR)

If the data processing is based on Article 6 sec. 1 lit. e or f GDPR, you have the right at any time to object 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 privacy policy. If you object, we will no longer process your personal data concerned unless we can prove compelling legitimate grounds for processing that outweigh your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims (opposition under Art. 21 sec. 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 the purpose of such advertising; this also applies to profiling in so far as it is related to such direct marketing. If you object, your personal data will no longer be used for the purpose of direct marketing (opposition under Art. 21 sec. 2 GDPR).

Right to complain to the competent supervisory authority

In the event of breaches of the GDPR, the persons concerned shall have the right to complain to a supervisory authority, in particular in the Member State of their habitual residence, place of work or the place of the alleged infringement. The right to appeal is without prejudice to other administrative or judicial remedies.

Right to data portability

You have the right to have data that we process automatically processed on the basis of your consent or in fulfilment 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

For security reasons and to protect the transmission of confidential content, such as orders or requests that you send to us as a site operator, this site uses an SSL or/or TLS encryption. You can recognize an encrypted connection by changing the address line of the browser from “http://” to “https://” and by the lock icon in your browser line.

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

Information, blocking, deletion and rectification

Within the scope of the applicable statutory provisions, you have the right to free information about your stored personal data, its origin and recipient and the purpose of the data processing and, if necessary, a right to rectification, blocking or deletion of this data. You can contact us at any time at the address given in the imprint for further questions on the subject of personal data.

Right to restrict processing

You have the right to request the restriction of the processing of your personal data. You can contact us at any time at the address given in the imprint. The right to restrict processing exists 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 examination, you have the right to request the restriction of the processing of your personal data.
  • If the processing of your personal data has been/happens unlawfully, 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 deletion.
  • If you have an objection under Article 21(0) of the 1 GDPR, a balance must be made between your interests and our interests. 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 be processed, except for its storage, only with your consent or for the assertion, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of an important public interest of the European Union or a Member State.

Objection to promotional e-mails

The use of contact data published within the scope of the imprint obligation for sending unsolicited advertising and information materials is hereby objected to. The operators of the pages expressly reserve the right to take legal action in the event of unsolicited sending of advertising information, e.g. by spam e-mails.

Use of Google Analytics

This website uses the web analytics service, Google Analytics. Google Analytics uses cookies, which are stored on your computer and enable us to analyze how you use our website. The information that is generated by the cookies about your use of our website is usually sent to a Google server in the USA and stored there.

Due to the activation of IP anonymization on this website, your IP address will first be abbreviated by Google within member states of the European Union or in other states that are party to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transferred to a Google server in the USA and abbreviated there. As a rule, no data is forwarded to a third country, but if this is the case, this is done within the framework of appropriate guarantees within the meaning of Article 46 of the EU GDPR.

Google will use this information on behalf of the operator of the website to evaluate your use of the website, compile reports about website activities and to provide further services associated with website and Internet use to the website operator.

The IP address transferred by your browser within the scope of Google Analytics will not be merged with other Google data. You can prevent the storage of cookies by selecting the appropriate settings in your browser software. However, we must point out that in this case, you may not be able to use all the functions of the website to their full extent.

You can also prevent the collection of data generated by cookies about your usage of the website (incl. your IP address) by Google, as well as the processing of this data, by downloading and installing the browser plugin available at the following link:

This is also based on Article 6(3). 1 lit. f GDPR. If you have questions about your contract or wish to conclude a contract, the processing is based on Art. 1 lit. b GDPR.
