Privacy Policy: A custom audience pixel is a tiny piece of javascript code that we have incorporated into this webpage. This piece of code provides a series of functions for transmitting application-specific events and user-defined data to Facebook. We use Custom Audience pixels to record information about the way visitors use our webspite. For this reason, this webpage contains a custom audience pixel. This pixel records information about the user's browser session, which it sends to Facebook, along with a hashed version of the Facebook ID and the URL viewed. Every Facebook user has a unique, device-independent Facebook ID that allows us to address and recognize users across a range of devices using the Facebook social network, so that we can address our visitors for commercial purposes using Facebook ads. The user information will be deleted after 180 days, until the user visits our website again. "Custom Audience from your website" respects your privacy. Thus, no personal information about individual visitors to the website is disclosed to us, and we can only advertise website customer target groups in a targeted way once the customer target group has reached a critical mass. This makes it impossible for us to discover the identity of individual visitors.
