Why do websites ask permission to use cookies?

Websites ask for cookie permission because some cookies and similar technologies require user consent under applicable privacy rules.

In the EU and EEA, the ePrivacy framework generally requires consent before information is stored on or accessed from a user’s device unless an applicable exemption applies.

A cookie consent banner gives visitors information about optional technologies and allows them to choose whether categories such as advertising, analytics, or personalization can be used.

Not every cookie requires consent. Technologies that qualify for an applicable exemption may be used without prior consent.
