Consent RequiredYes — requires explicit opt-in

Category: Functional

Functional cookies enhance the website's functionality and personalisation. They may be set by us or by third-party providers. Consent is required under GDPR.

GDPR Requirements

Under GDPR and the ePrivacy Directive, the wcsid cookie requires explicit user consent before it can be set. This means:

  • The cookie must not be set when a user first visits your site — not even for a fraction of a second
  • A consent banner must be displayed, and the user must actively accept analytics/marketing cookies
  • If the user rejects or ignores the banner, this cookie must remain blocked
  • The cookie must be listed in your cookie policy with its name, purpose, and retention period
  • Users must be able to withdraw consent at any time, which must also remove or invalidate this cookie

How to Handle This Cookie

  1. Block it by default — configure your Consent Management Platform (CMP) or tag manager to prevent Olark from loading until the user accepts functional cookies.
  2. Include it in your consent categories — map it to the "Functional" category in your CMP configuration.
  3. List it in your cookie policy — document the cookie name, purpose, provider (Olark), and expiry (Session).
  4. Sign a DPA — ensure you have a Data Processing Agreement with Olark covering their use of data collected via this cookie.
  5. Verify it works — in an incognito browser, reject cookies and confirm wcsid is not set.
