A UUID is a sequence of 32 hexadecimal digits, used to identify your website visitors. VWO drops a cookie in the browser settings for all your website visitors, which contains the unique identification code, such as 3F2504E04F8911D39A0C-0305E82C3301. The VWO UUID is browser-specific and can differ for the user across multiple browsers.
With the help of VWO UUID, a VWO user can request to access or delete data for a particular UUID.
