I. General terms
Data protection serves to protect your personal information. Personal information is all information concerning an identified or identifiable natural person, e.g. name, address or e-mail address.

That is why it is fundamentally possible to visit our website without you having to disclose your identity to us. If on our website you use the contact form or one of the stated e-mail addresses, for example, this requires you to disclose your identity. We are unable to respond to anonymous requests.
