GDPR requirements

Analytics cookies help website owners understand how visitors interact with websites by collecting and reporting information anonymously. Consent is required under GDPR.

For _vis_opt_s to be compliant, it must be:

  • Not set on the first visit — not even for a fraction of a second
  • A consent banner is shown, and the visitor actively accepts analytics cookies
  • Stays blocked if the visitor rejects or ignores the banner
  • Listed in your cookie policy with its name, purpose and retention period
  • Removed or invalidated when the visitor withdraws consent

How to handle it

  1. 1
    Block it by default

    Configure your consent platform (CMP) or tag manager so VWO doesn't load until the visitor accepts analytics cookies.

  2. 2
    Map it to a consent category

    Put it under “Analytics” in your CMP configuration.

  3. 3
    List it in your cookie policy

    Name, purpose, provider (Wingify Software Pvt. Ltd.) and expiry (100 days).

  4. 4
    Sign a DPA

    Have a Data Processing Agreement with Wingify Software Pvt. Ltd. covering the data this cookie collects.

  5. 5
    Verify it works

    In a private window, reject cookies and confirm _vis_opt_s is not set.
