The _pk_ses.* cookie

_pk_ses.* is a cookie set by Matomo, from InnoCraft Ltd. Short-lived cookie that groups page views into one visit.

The * in the name stands for a part that changes from site to site, such as an account or measurement ID.

Does the _pk_ses.* cookie require consent?

_pk_ses.* is used for analytics, so under the GDPR and the ePrivacy rules it may only be set after the visitor has agreed. Showing a banner is not enough on its own: the cookie must not be set before the visitor clicks accept.

Does your site set _pk_ses.* before consent?

A free scan loads your site the way a new visitor sees it and lists every cookie that is set before anyone has said yes, _pk_ses.* included.

How to put _pk_ses.* behind consent

Remove the Matomo snippet from your site and add your Matomo ID under Integrations in Consentify instead. Consentify then loads Matomo only after the visitor has accepted analytics, so _pk_ses.* is never set before consent.
