The process of removing stored website data (including session and persistent cookies) from a user’s browser, a core right under GDPR and CCPA.

The right to erasure, or the “right to be forgotten,” mandates that data subjects must have an accessible, non-discriminatory method to revoke consent and have their data deleted.

Technically, this is fulfilled either through browser API calls or a direct function within the website’s privacy center.

Failure to provide a functional ‘opt-out’ or deletion mechanism for cookies and stored data violates the right to erasure (GDPR Art. 17). This operational mechanism demonstrates accountability to regulators. A CMP like Seers.ai records this action for audit proof.
