Our website and/or service does not intend to collect data about website visitors who are under 16 years of age, unless they have obtained permission from a parent or legal guardian. However, we cannot check whether a visitor is at least 16 years old. Consequently, we encourage parents to be involved in the online activities of their children in order to prevent data about children being collected without parental consent. If you are convinced that we have collected personal information about a minor without this consent, please use the contact form to get in touch with us and we will delete this information.
