Hello,
I don't speak German (only French and English), but the changes are related to new EU regulations, as stated in just published information on top of this site.
So, check the new Privacy Consent options documentation here:
icagenda.joomlic.com/docs/documentation/...ools/privacy-consent
Now, iCagenda is set as Privacy by default, and give webmaster tools to be GDPR compliant.
The big change with GDPR is that explicit consent should be stored as a proof of user consent, and no data should be public without the explicit content (that's big changes, as even the already existing Terms checkbox was not enough...)
So, the default result you get is just the privacy by default behavior.
So, read the documentation about the new privacy consent options, to manage it as you need it
Best regards,
Cyril
