Consent with pre-ticked boxes

Privacy (GDPR)Severity: Medium

Finds already ticked checkboxes inside the consent interface.

Why this matters

In “Planet49” (C-673/17, judgment of 1 October 2019) the CJEU held that a pre-ticked box does not constitute valid consent: agreement requires an active choice. Relying on it means processing without a legal basis.

Deliberately narrow: only visible, non-disabled boxes within the consent interface. Disabled boxes are typically the strictly necessary categories that need not be deselectable — they do not trigger a finding. Neither does a checkbox in a checkout form.

If the interface cannot be assessed (banner inside an iframe), the scan says nothing rather than guessing.

How to fix it

Leave every box unticked except the strictly necessary ones.
