Opt-out means that data processing is enabled by default and users must object afterwards . Unlike opt-in, consent is not given actively, but assumed until the user explicitly opts out.
In the EU, the opt-out model is no longer permitted for many forms of tracking or personalised advertising under current rulesbecause the GDPR generally requires active consent (Opt-in) ) .
Some uses remain possible, for example in the United States or for certain technical functions. In these cases, users can opt out through a “Disable cookies” link or consent-management settings.
Important: Opting out must be just as easy as opting in. It must not be hidden or made unnecessarily difficult.
