When using public registration there is no way to display the privacy notice.

Adding it via {{ include('./subviews/privacy/privacy.twig') }} doesn't appear to have the desired effect:

• the notice is displayed, but the mandatory box can be ignored, data can still be transmitted.

(though probably I'm doing something wrong).

When adding this properly to LimeSurvey, it might be necessary to differentiate between consent given on public registration and entering the survey by being in the participant db, so the notice isn't either shown twice (to public registrants) or never to previously registered users.
