It is important that the data protection regulations on the second page of the account page given to you by your school is signed. Children of legal age are able to sign this by themselves, but for underaged children parents are required to sign this form and accept it.

Once the data protection regulations have been signed, they are collected or have to be sent in by email (if they have been signed virtually or scanned after) and then have to be kept. They are also sent to Sdui via email or by post.
