Does the CLID cookie need consent?

In the EU and the UK, yes. CLID is an analytics cookie, so it may be set only after the visitor agrees. Under the CCPA, California residents can opt out if the data is sold or shared.

How long does the CLID cookie last?

CLID usually lasts 1 year. The exact lifetime depends on the site's settings and the version of the script that sets it.

Who sets the CLID cookie?

CLID is set by Microsoft Clarity. It is in the Analytics category.

How do I block or delete the CLID cookie?

Visitors can delete CLID in their browser's cookie settings. On your own website, a consent banner can keep the script that sets it waiting until the visitor accepts analytics cookies. Kukie.io's banner does this for known trackers by default, and for any other script you tag with its category.

Consent

Needed in the EU and the UK

CLID is in the Analytics category. In the EU and the UK, analytics cookies need the visitor's consent before they are set. California's CCPA works differently: it lets residents opt out of the sale or sharing of their personal information.

GDPR and ePrivacy (EU): Prior consent is needed before setting CLID. Analytics cookies are not covered by the strictly necessary exemption; only a few regulators (for example France's CNIL) allow a narrow exemption for first-party audience measurement under strict conditions.
UK GDPR and PECR: Consent is needed before setting CLID. The ICO treats analytics cookies as non-essential.
CCPA and CPRA (California): Disclose CLID in your privacy policy and honour opt-out requests, including the Global Privacy Control signal, if the analytics data is shared or sold.

Managing CLID with a consent banner

A consent banner can keep the script that sets CLID waiting until the visitor accepts analytics cookies. Kukie.io's cookie scanner finds CLID and sorts it into a category. The banner holds back known trackers by default, and any other script you tag with its category waits too.
