muxData Cookie

What does the muxData cookie do?

Vimeo uses a specific type of cookie called muxData to support various video player functionalities on the website. This cookie stores the playback state of videos displayed on our website. If playback is interrupted due to an unstable network connection or other unexpected issues, this cookie helps ensure that viewers can resume playing from where they last left off.

Why this cookie matters

This cookie is commonly used by wistia , vimeo for preferences purposes – such as tracking usage behaviour, optimising experience, or enabling marketing functionality.

Because it's categorised as preferences, many jurisdictions require that users give explicit consent before it can be activated. If blocked or denied by the visitor, preference-related features (like remembering language or layout choices) may not function properly.
