  • First- and last name
  • Address
  • Phone number

  • Other personal data that you actively provide e.g. by creating a profile on this website if you wish to book a lecture, or if you indicate that you wish to receive the newsletter or order a book.

Special and/or sensitive personal data we process

Our website and/or service does not intend to collect data on website visitors who are under 16 years of age. Unless they have parental or guardian consent. However, we cannot verify whether a visitor is older than 16. We therefore advise parents to be involved in their children's online activities to avoid collecting data on children without parental consent. If you are convinced that we have collected personal data about a minor without such consent, please contact us at info[@] (remove brackets) and we will delete this information

For what purpose and on what basis we process personal data

De Loef processes your personal data for the following purposes:

  • Handling your payment
  • To allow you to create an account to book a lecture
  • To deliver goods and services to you, such as a newsletter or a book

Automated decision-making

De Loef does not use automated decision-making (algorithms) to offer its services. The website may, however, start using advertisements by Google, for example. Then we - secondarily - use Google's network. We will carefully set that algorithm so that our website never features ads that are politically charged, that advertise things like alcohol, nicotine products or other addictive substances, or that are otherwise harmful.

How long do we keep your data

De Loef does not keep your personal data longer than strictly necessary to realise the purposes for which your data are collected.

Sharing personal data with third parties

De Loef does not sell your data to third parties and only provides them if this is necessary for the execution of our agreement with you or to comply with a legal obligation. For example, we may leave your address details to PostNL so that they can deliver a book to you. We conclude a processor's agreement with companies that process your data on our behalf to ensure the same level of security and confidentiality of your data. De Loef remains responsible for this processing.

How we secure personal data

How we secure personal data De Loef takes the protection of your data seriously and takes appropriate measures to counter abuse, loss, unauthorised access, unwanted disclosure and unauthorised modification. If you have the impression that your data is not properly secured or there are indications of abuse, please contact our customer service or via info[@] (remove brackets). De Loef has taken the following measures to secure your personal data:

  • Security software, such a firewall.
  • TLS (formerly SSL) We send your data over a secure internet connection. You can tell this by the ‘https’ address bar and the padlock in the address bar.
  • DKIM, SPF and DMARC are three internet standards we use to prevent you from receiving emails on our behalf that contain viruses, are spam or are intended to obtain personal (login) data.
  • DNSSEC is an additional security (complementary to DNS) for converting a domain name to its associated IP address; it is provided with a digital signature. You can have that signature checked automatically. This prevents you from being redirected to a false IP address.
