Consent & visitor IDs

MetricRaven works without consent and connects visits across days once storage is allowed.

How visitor IDs work

Before consent: the tracker uses a server-derived visitor ID that changes daily. Nothing that identifies the visitor is stored in the browser.

With consent: it keeps a random first-party identifier for up to a year, so visits on different days are easier to connect.

Connect your cookie banner

1. Set stored consent before the tracker loads

   If your banner already has stored analytics consent, set it before the MetricRaven script tag:

   index.html

   Copy

   5

   <script>
     // Only set true when the visitor has already allowed analytics storage.
     window.analyticsConsent = true;
   </script>
   <!-- Your MetricRaven script tag goes after this. -->

2. Call setConsent from your banner

   Once the tracker is loaded, wire up the banner's accept and withdraw handlers:

   script.js

   Copy

   1

   // Call these from your cookie banner's accept / withdraw handlers.
   window.analytics?.setConsent(true);
   window.analytics?.setConsent(false);
