Consent

Needed in the EU and the UK

lu is in the Marketing category. In the EU and the UK, it needs the visitor's consent before it is set. Under California's CCPA, visitors can opt out of the sale or sharing of their personal information, including for cross-context behavioural advertising.

GDPR and ePrivacy (EU): Prior consent is needed before setting lu. Advertising and tracking cookies are never covered by the strictly necessary exemption.
UK GDPR and PECR: Consent is needed before setting lu.
CCPA and CPRA (California): Setting lu for cross-context behavioural advertising counts as sharing personal information: offer a "Do Not Sell or Share My Personal Information" opt-out and honour the Global Privacy Control signal.

Managing lu with a consent banner

A consent banner can keep the script that sets lu waiting until the visitor accepts marketing cookies. Kukie.io's cookie scanner finds lu 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.
