All personal data that you transmit to us during the surfing process in general and in particular during the ordering process are transmitted in encrypted form and are thus protected against misuse. In particular, we set up a so-called SSL connection for every transaction. SSL (Secure Socket Layer) is a process in which your data is encrypted in such a way that it cannot be read by unauthorized persons while it is being transmitted over the Internet.

You can recognize the SSL connection by the fact that the Internet address has changed from http: // to https: //. In addition, the secure connection is usually indicated in the status bar of your web browser by a closed padlock.

Social plugins from the social networks Facebook and Instagram are integrated into our website. These are offers from the US company Facebook Inc. (1601 S. California Ave, Palo Alto, CA 94304, USA). You can recognize the plugins by the respective company logos.

Before clicking on the Facebook / Instagram button, with the help of the data protection-friendly alternative (Shariff button) used, only the server address is transmitted to Facebook instead of the visitor's IP address. As long as the user does not click on the link to share content, he remains invisible, at least for Facebook & Co.
