DDI is not required to appoint a data protection officer and has not appointed one. Questions about this statement go to support@delftdrones.eu.

This statement covers the DDI website, registration for our activities, and our community subscription. Cookies are covered separately in our Cookie Statement.

2. Where we get your data

Most of the data we hold comes from you: when you create an account, register for an activity, pay, subscribe, or contact us.

Where a parent or guardian registers on behalf of a child, they conclude the agreement and provide the child’s details. The child has the same rights over that data as anyone else, and section 9 explains how to use them.

Where someone passes their place at an activity to you, we send them a transfer link and they pass it to you, so you register yourself and we receive your details from you directly. If they send us your name or email instead, we use it only to send you that link, and delete it if you do not register.

Where we rely on legitimate interest, we have weighed our interest against your privacy. You can object to that processing, and section 9 explains how.

What is required. Your name, email, age and payment details are needed to conclude the agreement. Without them we cannot register you. Everything else — telephone number, newsletter, photo consent — is optional, and refusing has no consequence other than the obvious one of us not being able to do that particular thing.

4. Your account

Your account holds your registration history, your subscription status, and your preferences for the newsletter and for photography. You can change your preferences there at any time. You can ask us to close your account, and we will, subject to the retention periods in section 3 — most importantly the seven years we must keep financial records.

5. Incidents and injuries

We do not ask for medical or health information when you register, and you should not send it to us.

One part of our activities can nevertheless involve health information, which the GDPR treats as a special category needing stricter handling. If someone is hurt at our facility, we record what happened. That record may describe an injury. We keep it because we have a duty of care, because we learn from incidents, and because a claim may follow. Health information may only be processed on one of the narrow grounds the GDPR allows. Where an incident record contains health information, we rely on the ground that permits such processing where it is necessary for establishing, exercising or defending legal claims.

We keep incident records for five years. Where the person involved was under 18, we keep the record until they turn 23, because the period in which a claim can be brought does not begin until they reach 18.

Where emergency treatment is needed, we may pass information to emergency services without asking first, because your vital interests come first.

6. Photography and video

Photographs and video are taken at our activities. Faces are blurred in anything we publish, unless you have separately consented to being shown unblurred. That consent is optional, is never a condition of taking part, and can be withdrawn at any time in your account or by emailing us.

Withdrawing consent applies to future use. We will remove or blur the material within a reasonable time, but we cannot undo sharing that has already happened, for example by someone who reposted it.

If you do not want to be photographed at all, tell the supervisor at the start of the activity.

Published material is kept for as long as it remains in use.

We also keep photographs and video as a record of our activities, so that we have an overview of what we have done. Original files are kept for five years after the activity and are then deleted. You can object at any time under section 9, and where you do, we remove or blur the material concerned before that period ends.

7. Children

Participants can take part from the age of 12. Where the participant is under 18, the parent or guardian concludes the agreement and provides the details.

For personal data, Dutch law sets the age of consent at 16. Where the participant is 16 or 17, they give their own consent for the newsletter and for photography. Where the participant is under 16, the parent or guardian gives that consent.

A parent or guardian may exercise the rights in section 9 on behalf of a child under 16.

8. Who else sees your data

We do not sell personal data and we do not share it for anyone else’s marketing.

We use the following service providers, who process data on our instructions under a processing agreement:

Provider What for Where
Contabo Website and database hosting Germany
Stripe Payment processing Ireland, with transfers to the United States
Google Website analytics, only with your consent United States

We do not currently send a newsletter. Any email we send you, including registration confirmations and account messages, is sent from our own servers in Germany. If we later use an external newsletter provider, we will name it here before we start.

Instagram and LinkedIn receive data when embedded content on our site is loaded, and only if you consented. Those platforms act for their own purposes, not on our instructions. See the Cookie Statement.

We also share data where the law requires it, for example with the tax authorities, and with our accountant, insurer or legal adviser where a specific matter makes that necessary.

9. Your rights

You can ask us to:

  • give you a copy of the data we hold about you
  • correct anything that is wrong or incomplete
  • delete your data, where we have no continuing reason to keep it
  • restrict what we do with it while a question about it is resolved
  • transfer it to you or another organisation in a machine-readable form
  • stop processing based on legitimate interest, by objecting
  • withdraw consent you gave for the newsletter, photography or cookies. Every newsletter also contains an unsubscribe link, and you can switch the newsletter off in your account at any time

Withdrawing consent is as easy as giving it, and does not affect processing that already took place.

Email support@delftdrones.eu. We reply within one month. If a request is complex we may take two months more, and we will tell you before that first month is up. It is free, unless a request is excessive, and we may ask you to confirm who you are before we send personal data.

If you are unhappy with how we handle your data, tell us first so we can put it right. You also have the right to complain to the Dutch Data Protection Authority, the Autoriteit Persoonsgegevens, at autoriteitpersoonsgegevens.nl.

10. Transfers outside the EEA

Our website and database are hosted in Germany, and registration data stays there.

Some of our providers transfer data to the United States. Google and Stripe participate in the EU–US Data Privacy Framework, and the European Commission has decided that organisations certified under it offer an adequate level of protection. Where a provider does not rely on that framework, we use the European Commission’s standard contractual clauses. You can ask us for a copy of the safeguards that apply to a particular transfer by emailing support@delftdrones.eu.

11. Security

Access to the database is limited to the people who need it. The website uses encrypted connections, passwords are stored hashed, and we keep backups. Where a data breach presents a risk to you, we will notify the Autoriteit Persoonsgegevens and, where required, you.

12. Automated decisions

We do not make decisions about you by automated means and we do not profile you.

13. Changes

We may amend this statement, for example if we change a service provider. The version and date at the top show when it last changed. Where a change materially affects you, we will tell you.
