I am Hugo van de Haar, a sole trader in the Netherlands and the controller of the personal data described here. Business details.
For privacy questions or requests, email hugo@vandehaar.com. I do not sell personal data or use it for advertising.
Visiting the site
Netlify hosts this website and processes technical request data, such as your IP address, browser, requested page and request time, to operate and secure it.
Netlify’s performance measurement records loading speed, responsiveness and layout stability without cookies. Fonts and research figures are hosted with the site. There are no advertising pixels or session recordings.
This processing supports my legitimate interest in running a secure, usable website. I do not connect reading activity to email subscribers. The external booking calendar works as described below.
Contact and booking
The contact form prepares a draft in your email app. It does not submit your message to this website. You decide whether to send it.
Choosing “See available times” on the booking page, or opening its calendar link, loads Cal.com. It receives technical connection data and may use its own cookies. When you book, your name, email address and time zone pass to the booking service and my calendar. The same applies to any phone number, company website or notes you add. You can email me to arrange a time instead.
I use correspondence and booking details to answer your enquiry or arrange work at your request. The basis is taking steps towards a contract, performing a contract, or my legitimate interest in responding to other correspondence.
I keep these records while they are needed for the conversation, an engagement or a related claim. Basic records required for Dutch tax administration are kept for seven years. Other correspondence is deleted when it is no longer needed.
Edition emails
If you subscribe, I use your email address to send one email when a new edition of The Demand Side is published. There are no offers or other messages between editions. Subscription is optional and based on your consent.
Netlify processes the form submission, including technical information used for handling and spam checks. I use the address to send the edition emails through my email service. I do not track opens or clicks.
Reply to an edition email or write to me to unsubscribe. Your address is kept until you withdraw consent or the list closes, then removed from the notification list.
Research
The research uses public company websites, filings, announcements and job listings. A person’s name or professional role may appear as part of a company’s public record. The research examines companies; it does not build profiles of individuals.
The basis is my legitimate interest in researching and publishing about the space economy. Source records are kept where needed to support or correct a finding. Please email me if a record about you is inaccurate.
Service providers and storage
Netlify provides hosting and forms; Cal.com handles bookings. Email and calendar providers process correspondence and meeting details. These records are not stored in the public website files. The site uses HTTPS.
Providers may process data outside the European Economic Area. Their transfer safeguards include standard contractual clauses or an applicable adequacy mechanism. Details are in Netlify’s data processing agreement and Cal.com’s privacy policy.
Your rights
You can ask to access, correct or delete your personal data, restrict its use, object to processing or request a portable copy, where those rights apply. You can withdraw consent at any time; this does not affect earlier lawful processing. I do not use automated decision-making or profiling.
Email hugo@vandehaar.com. I normally respond within one month. If a request needs a lawful extension, I will explain this within that month.
You can complain to the Dutch Autoriteit Persoonsgegevens or your local data protection authority. The date above changes when this policy is updated.
