You may ask us to give you access to your data, to correct, erase or transfer it, and to restrict or object to the processing. Consent you have given may always be withdrawn; that does not affect what happened before.
One email to klantenservice@cursus-group.nl is enough. We respond within 30 days. To avoid handing data to the wrong person, we may ask you to show that you are who you say you are.
If you disagree with what we do, you can complain to the Dutch Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl). We would rather hear it ourselves first, so we have a chance to fix it.
