The purposes are in accordance with Article 13, Section 1 c GDPR and our legitimate interests within the meaning of Article 13, Section 1 d) in conjunction with Art. 6 Section 1  f GDPR). In collecting, processing, using and storing personal data, we comply with the principles of legality, good faith, transparency, restriction to purpose, data minimisation, accuracy, storage limitation, integrity and confidentiality (principles as defined by Art. 5 Section 1 GDPR).

Legal basis for the collection, processing, use and/or storage of your personal data:

the legal basis for any collection, processing, use and/or storage of your personal data is in particular Art. 6 Section 1 a), b), c), d) and/or f) GDPR.

Personal entries:

in addition, your personal data (e.g. name, address, email address, telephone number, message etc.) will only be collected, processed, used and/or stored if you provide it to us of your own accord, e.g. by entering it in contact forms. Your data will only be used for the purpose stated on the respective page, e.g. within the scope of your contact enquiry or application.
If you access pages, files or other information via our public website and are asked to enter personal data, please note that the related data transfer via the Internet is unencrypted. The data can thus be accessed or falsified by unauthorised persons.

Handling email addresses:

if you send us an email, we will only use your email address for correspondence with you. Your email address will not be passed on without your prior consent.


we use technical and organisational security measures to protect the data we administer from manipulation, loss, destruction and access by unauthorised persons. Our security measures are continuously improved in line with technological developments.


cookies are small amounts of data that are stored on your computer by the operator of a website.
We use temporary and permanent cookies on our website. Temporary cookies contain data such as an identification number (so-called ‘session ID’). They allow the server to assign successive browser requests to the same user. They are automatically deleted as soon as the user closes the browser.
Permanent cookies, however, are retained even after the user has closed the browser. They are automatically deleted after a specified period, which may vary depending on the cookie. You can delete cookies at any time in the security settings of your browser.
You can configure your browser settings according to your wishes and refuse the acceptance of third party cookies or all cookies, for example. So-called "third-party cookies" are cookies set by a third party, therefore not by the actual website you are currently visiting. Please note that you may not be able to use all functions of this website by deactivating cookies.

Links to other websites:

if you call up an external website from our website (external link), the external provider may receive information from your browser about the page from which you accessed it. The external provider is responsible for this data. Like any other website operator, we are not in a position to influence this process.

Data transmission:

information transmitted via the Internet (e.g. also when communicating by email) is usually unencrypted. Since the path of the data between the server and the local PC can never be predicted exactly, transmitted information can be viewed in many places. We therefore draw your attention to these security vulnerabilities. The complete protection of data against access by third parties is not possible.

Recipients of personal data:

The employees and external service providers entrusted with the administration of our website and our internal IT structure are recipients / categories of recipients of personal data within the meaning of Article 13, Section 1 e GDPR.
We use external service providers (contractors), e.g. DATEV eG, Nuremberg, to fulfil the client agreement. A separate order data processing agreement has been concluded with the respective service provider in order to guarantee the protection of your personal data.

Information according to Art. 13 Section 2 GDPR:

the General Data Protection Regulation (GDPR) and the Federal Data Protection Act (BDSG), to whose content full reference is made, apply.

If we have stored personal data about you, you can obtain information about your personal data stored on request free of charge. Please inform us if we have stored incorrect data about you so that we can correct, block or delete it.

Integration of Google Maps

On this website we use the Google Maps service. This allows us to display interactive maps directly on the website and enables you to conveniently use the map function.
When you visit the website, Google receives the information that you have called up the corresponding subpage of our website. In addition, the data collected when you visit our website is transmitted. This is regardless of whether Google provides a user account that you are logged in with, or whether no user account exists. If you are logged in to Google, your information will be directly associated with your account. If you do not wish to be associated with your profile on Google, you must log out before activating the button. Google stores your data as usage profiles and uses it for purposes of advertising, market research and/or demand-oriented design of its website.
