  • the right to be informed,
  • the right to rectification or erasure,
  • the right to restriction of processing,
  • the right to object to processing based on § 6 (1) S. 1 lit. f,
  • the right to data portability.

In addition, you have the right to lodge a complaint with a supervisory authority about our processing of your personal data.

Contact and contact forms

You can send us a request using the email addresses provided or our contact forms. We will save the personal data made available to us in this connection (e.g. first name, last name, email, street, zip code, city, phone number and subject matter) to process your request. We will forward your personal data to recipients where this is necessary to deal with your request. We will delete all data in this connection once their storage is no longer necessary, or restrict processing if data are subject to statutory retention requirements.

The legal basis for processing your personal data depends on your request and may result from a contract with you (§ 6 (1) S. 1 lit. b GDPR), your consent (§ 6 (1) S. 1 lit. a GDPR) or for the purposes of our legitimate interests (§ 6 (1) S. 1 lit. f GDPR) in offering you a good service.

We will process your data – if processing is based on your consent – until you revoke your consent or – if processing is based on the pursuit of legitimate interests – until you object to this, or for the purpose of your request until it has been dealt with. It is not possible to process your request unless you provide the data required for us to contact you and understand and process your request. All further data are provided on a voluntary basis. This service is only for people over the age of 18.

Collection of personal data when visiting our website

When using the website for information purposes only, i.e. without registering or providing any other information, we collect only the personal data that your browser transmits to our servers. If you would like to view our website, we will collect the following data, which are technically required to display our website to you and guarantee stability and security (legal basis is § 6 (1) S. 1 lit. b GDPR in conjunction with § 32. (1) GDPR and § 13 (7) Telemedia Act (Telemediengesetz – TMG)):

  • IP address
  • Date and time of your request
  • Time zone difference to Greenwich Mean Time (GMT)
  • Content of request (concrete page)
  • Access status/HTTP status code
  • Data volume transferred in each case
  • Website from which the request is received
  • Browser
  • Operating system and its user interface
  • Language and version of the browser software.

These data with full, possibly personal IP addresses, saved by us for reasons of technical security, in particular to defend against attempted attacks on our web server, will be anonymized/erased at the latest after 7 days.

Convenience functions

To ensure our website is displayed optimally (e.g. adjustment to different monitor screen sizes, drop-down menu, input control for contact form) we use languages such as JavaScript and CSS (cascading style sheets). You can use corresponding settings on your browser to deactivate the use of these languages. However this may render parts of our website unusable.

Social Media

At various points of our website we provide links to social media platforms such as Facebook and Instagram, marked with the logos of the social media providers for easy identification. Using our website does not send any personal data to the providers of these social media platforms. Only when you click on one of the links will you be taken to the respective social media website, at which point personal data will be transmitted to the provider. As a result, you leave our website and we have no influence over the data collected or the way they are processed, nor are we aware of the scope and purpose of data collection and the duration of their storage.

Clicking on one of these links informs the social media provider that you accessed the corresponding page of our website. In addition the data listed in the section “Collection of personal data when visiting our website” of this privacy statement will be transmitted. This will happen regardless of whether you have an account with this social media provider and are logged in. If you are logged in to the social media provider, these data are allocated directly to your account.

Social media providers store personal data as user profiles and use them for advertising, market research and/or the tailored design of their website. In particular, the data are analyzed (even for users who are not logged in) to display tailored advertising and to inform other users of the social network about your activities on our website. You have the right to object to the creation of these user profiles; to exercise this right you will need to contact the social media providers.

For more information on the scope and purpose of data collected and how they are processed by the social media provider, please find the privacy statements of these providers below. They also contain further information on your rights and the options available to you to protect your privacy.
