The SIGMA website may embed components (videos) from YouTube LLC, 901 Cherry Ave., San Bruno, CA 94066, USA, which is part of Google Inc., Amphitheatre Parkway, Mountain View, CA 94043, USA.

When you access a SIGMA web page with an embedded YouTube video, a connection to a server of YouTube will be established, and the corresponding content displayed in your web browser. SIGMA activates YouTube’s “privacy-enhanced mode” when embedding videos on its own website. According to YouTube, when using the “privacy-enhanced mode”, YouTube will only receive or store information about the SIGMA page you were using while watching the video when you start the video. If you are simultaneously signed in with your YouTube account, this information will also be registered in your YouTube account. You can avoid this by logging out from your YouTube account before visiting our website. Further details are provided by Google under the following link: YouTube
