If you want to stay informed if something happens to your data, you can turn on 'Notifications' in the settings of your Personal Portal.
You will receive a notification by e-mail if something happens to your data. The email will also feature the last three digits of the your Civic Service Number ('BSN-nummer'). This way you can see who the message is about. This is especially useful if several people in a household use the same email address.
You can set notifications by logging in to the Personal Environment.
