What is the svSession cookie?
svSession is an HTTP cookie automatically set by Wix on any site built and hosted through this platform. It appears as soon as a visitor loads a page, regardless of whether they are logged in or browsing anonymously.
The cookie is part of Wix's core technical infrastructure (Wix Data Services) and cannot be selectively disabled by the site owner without breaking basic functionality, since it is managed directly by the platform rather than by the site's own code.
What data it stores
- Stores a unique session identifier generated by Wix servers for each visitor
- The exact value format is internal to Wix's platform and not publicly documented in detail
- Data is sent to Wix servers, which handle the application logic (login, shopping cart, forms, site members)
- Typical lifespan is around 2 years, though this may vary depending on the site's configuration
What it is used for
For Wix, svSession maintains session continuity as a visitor moves between pages: it keeps members logged in, retains the contents of a Wix Stores shopping cart, and allows forms and other interactive components to work correctly.
For the site owner, this cookie is essential for Wix-built applications (online store, members area, bookings) to function properly, independent of any marketing or analytics goals the site may have.
Does it require consent?
svSession is classified as a strictly necessary cookie, since it supports core technical functions without which the site cannot operate correctly (session handling, cart, login). Under ePrivacy rules (implemented in Romania via Law 506/2004) and GDPR guidance, strictly necessary cookies do not require prior consent.
Even though visitor consent isn't required, the site owner must still list svSession in the cookie policy, describing its actual purpose and duration, to meet GDPR transparency obligations.
How to block or delete svSession
A visitor can delete or block svSession through browser settings (Chrome, Firefox, Safari, Edge) in the cookies and site data management section. Blocking it may break essential features, such as placing an order or staying logged into a member account.
Because it is strictly necessary, this cookie should not be held back pending consent by a CMP like CookieFix, which automatically blocks only cookies in the statistics, marketing, and preferences categories. svSession remains active from the first visit but must be accurately declared in the cookie policy shown via the banner.
