How is your personal data processed (cookies)?

When you visit our website, no personal data is collected from you. Specific data is evaluated and stored on our web server each time you visit our website, but only for statistical surveys and to guarantee the security and stability of the system.

For technical reasons, your Internet browser automatically transmits data to our web server when you access our website.

Please also note that cookies can only be retrieved by the creator of the cookies. This means that no other online providers can read these cookies.
