What is the _wixCIDX cookie?
_wixCIDX is an HTTP cookie automatically created by the Wix platform on any website built and hosted using the Wix site builder. It appears on the very first page load, regardless of visitor actions, because it is part of the technical infrastructure Wix provides to site owners.
It is not set directly by the website administrator but by Wix's own scripts and backend platform running behind the scenes. Site owners generally cannot remove this cookie without affecting how the Wix-hosted site functions, since it relates to how Wix delivers and manages site content.
What data it stores
The cookie typically stores a unique technical identifier (correlation- or session/visitor-type), without directly containing personal identifiers such as a name or email address. The exact value format is not publicly documented by Wix and may vary; no further confirmed technical details are publicly available.
The value is read by Wix's scripts loaded on the site and sent to Wix's servers/infrastructure to support correct page and platform operation.
What it is used for
_wixCIDX helps Wix's infrastructure recognize and correlate requests coming from the same visitor or session while browsing the site. This supports the site's technical stability, correct request routing, and the basic functioning of Wix components embedded in the page.
For the website administrator, this cookie does not provide directly usable statistics or marketing data; its role is purely technical, helping ensure a Wix-built site loads and works properly.
Does it require consent?
In CookieFix's classification, _wixCIDX is categorized as strictly necessary (required for the website to function). Under the ePrivacy Directive (transposed in Romania via Law 506/2004) and ANSPDCP's guidance, strictly necessary cookies do not require prior visitor consent, unlike statistics, marketing, or preference cookies.
Even though consent is not required, under GDPR the site administrator must still list this cookie in the site's cookie policy, along with its purpose and duration, for transparency toward visitors.
How to block or delete _wixCIDX
A visitor can delete or block this cookie at any time from browser settings (Chrome, Firefox, Edge, Safari) by clearing browsing data for that domain or configuring the browser to block cookies from that site. Blocking it, however, may affect how the Wix-built site functions.
- Since it is classified as strictly necessary, this cookie should not be auto-blocked before consent by a CMP banner.
- A platform like CookieFix can still scan and correctly document it in the site's cookie policy, alongside the other cookies detected on the site.
