* Google Adwords Conversion Tracking

To statistically record the use of our website and to evaluate it for the purpose of optimizing our website, we also use Google conversion tracking. Google Adwords sets a cookie on your computer if you have reached our website via a Google ad.


These cookies lose their validity after 30 days and are not used for personal identification. If the user visits certain pages of the Adwords customer's website and the cookie has not yet expired, Google and the customer can recognize that the user clicked on the ad and was redirected to this page.

Each Adwords customer receives a different cookie. Cookies can not be tracked via the websites of Adwords customers. The information gathered using the conversion cookie is used to generate conversion statistics for Adwords customers who have opted for conversion tracking. Adwords customers hear the total number of users who clicked on their ad and were redirected to a conversion tracking tag page. However, they do not receive any information that personally identifies users.

If you do not agree with the tracking, you can prevent the installation of cookies by a corresponding browser setting (deactivation). They will not be tracked during conversion tracking. Google's privacy policy on conversion tracking can be found here ( or here (

Our newsletters can contain so-called pixel counts: these are embedded in HTML emails in the form of a miniature graphic to document whether and when an email has been opened and which email client type and which type of terminal has been used. It also shows if and when a link was clicked in an email. We collect this data anonymously - we do not know who opened an email or clicked on a link or who uses which email client or device. The data collected in a log file are only for the statistical evaluation of the success of an online marketing campaign and the optimization of shipping.
