Social plug-ins from Facebook (Like-Button)

The information about your use of this website and online offers generated by the cookie is transmitted to a Google server in the USA and stored. The Zweibrüder Optoelectronics GmbH & Co.

Google uses this information to evaluate your use of the website, to compile reports on website activities for the website operators, and to render other services associated with the use of the website and the Internet. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf.

Please note that Google has its own privacy guidelines which are independent from ours. We assume no responsibility or liability for these guidelines and procedures. Please inform yourself of Google’s privacy policy before using our website. As an AdWords customer we also use Google Conversion Tracking, an analysis service from Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; "Google"). A cookie by Google AdWords will thereby be set on your computer (“Conversion Cookie”) if you arrive at our website via a Google advertisement. These cookies expire within 30 days and are not used for personal identification purposes. If you visit certain pages of ours and the cookie has not yet expired, we and Google can recognize that someone has clicked on the advertisement and was thus transferred to our website. Each AdWords customer receives a different cookie. Cookies can therefore not be traced back to the websites of AdWords customers. We use the information collected by the conversion cookie to provide aggregate conversion statistics to advertisers who have opted for conversion tracking. AdWords customers are informed of the total number of users who have clicked on their advertisement and were transferred to a site that has a conversion tracking tag. However, they do not receive any information, which allow users to be personally identified. If you do not want to be included in the tracking procedure, you can also reject the use of cookies which is necessary for this purpose – for example, by a browser setting which deactivates the automatic use of cookies in general.
