We use Vimeo to embed videos on our site. When a video is loaded, Vimeo sets cookies that are necessary for secure playback and to prevent abuse (like bot traffic). These are considered essential for the video to work properly. We also use a setting (dnt=1) that disables Vimeo’s own analytics and tracking features.
If you visit a page containing a Vimeo video and you are logged in to your Vimeo account or if you’ve visited the Vimeo website before ourwebsite, Vimeo may use cookies to keep you logged in, for analytics and advertising purposes, and collect data linked to your Vimeo account which we cannot control.
For more details, please see Vimeo’s cookie policy.
