Does the OSID cookie need consent?

In the EU and the UK, yes. OSID is a marketing cookie and needs consent before it is set under the GDPR, the ePrivacy rules and PECR. Under the CCPA and CPRA, visitors can opt out of its use for cross-context behavioural advertising.

How long does the OSID cookie last?

OSID usually lasts 6 months. The exact lifetime depends on the site's settings and the version of the script that sets it.

Who sets the OSID cookie?

OSID is set by Google. It is in the Marketing category.

How do I block or delete the OSID cookie?

Visitors can delete OSID 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 marketing 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

OSID 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 OSID. Advertising and tracking cookies are never covered by the strictly necessary exemption.
UK GDPR and PECR: Consent is needed before setting OSID.
CCPA and CPRA (California): Setting OSID 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 OSID with a consent banner

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