Needed in the EU and the UK

UK GDPR and PECR: Consent is needed before setting datr.
CCPA and CPRA (California): Setting datr 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 datr with a consent banner
