Enrolment and the parent portal in Classter

You enrol your child in Classter, which is also where the parent portal is. There you give your name, email and phone number, your child’s details and the birth certificate. We need them to place your child in the right class, tell you about lessons and call you if we have to.

 

The Education Coordination Office in Brussels asks for the birth certificate to enrol your child, so we send it there. We keep our copy in Classter while your child attends and one year after.

 

The school’s teachers see the details, and the board members who need them. Classter stores them for us and doesn’t use them for its own purposes.

 

 

Membership fee

 

You pay the fee with a Tikkie or by bank transfer to the association’s account. We keep the name and IBAN the payment came from, because Dutch law asks us to keep our accounts for seven years.

 

 

Photos and videos of the children

 

When you enrol in Classter, we ask whether we may show photos or videos of your child from lessons and celebrations. We ask again every school year. Without your yes, we don’t show your child anywhere. We never add a surname. On the Tile Wall we show only the tile and the first name.

 

Changed your mind? Email privacy@gsdh.nl and we’ll take the photo or tile down as soon as we can, within a month at the latest. We can’t recall what’s already printed, or what someone else has published, such as a TV report.

 

 

Teachers and board

 

Teachers’ and board members’ names, photos and bios appear with their consent. We take them down when they leave or when they ask.

Who else sees your details

Only the companies that work for us, and only for that work:

 

Classter (Vertitech) · Enrolment, parent portal, messages to parents · Greece, EU

Wix.com · Hosts the website, the forms and the newsletter · Israel and the USA. Israel has an EU adequacy decision. For the USA, the EU standard contractual clauses apply

Tikkie (ABN AMRO) · Paying the membership fee · Netherlands, EU

Google (Maps, YouTube) · The map and the videos on our pages · USA, under the EU-US Data Privacy Framework

 

The Facebook and LinkedIn buttons take you to their own pages, on their own terms. Apart from them, we share details only with the Education Coordination Office in Brussels, which asks for the birth certificate to enrol your child, and with any other public authority only when the law requires it.

 

 

Cookies

 

The site only sets the cookies it needs to work, such as the one that remembers your cookie choice. Cookies that count visits are added only if you click “Accept”. The map and the videos are Google’s. When they load, Google sets its own cookies.

 

Change your choice any time with the “Cookie settings” button at the bottom left of every page.

 

 

Security

 

Only people who need your details can see them, each with their own account. If there’s a data breach, we report it to the Autoriteit Persoonsgegevens within 72 hours and tell you if it affects you.

Your rights

We follow the General Data Protection Regulation (GDPR). You can see your details, have them corrected, ask us to erase them or limit how we use them, object to how we use them, and get them in a file a computer can read. Where we rely on your consent, you can withdraw it any time. What happened before stays lawful. For children under 16, parents act for them.

 

Email privacy@gsdh.nl and we’ll reply within a month. We may ask you to confirm who you are.

 

Not satisfied? You can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
