Privacy
This site sets no cookies, loads nothing from third parties, runs no analytics and has no forms, accounts or logins. What follows is the little that is left.
Who is responsible
Test Grond is a trade name of CNSDR, a sole proprietorship registered in the Netherlands under KvK number 88676471. CNSDR is the controller for the personal data described on this page. You can reach us at hello@testgrond.nl.
What the website processes
To send you a page, our web server unavoidably receives your IP address, the time of the request, the file you asked for, your browser's user agent and, if your browser sends one, the page you came from. We keep no access log, so once the page has been sent none of that is stored on our side. Our hosting provider processes some technical data at the infrastructure level to keep the server running and secure, under its own terms. Nothing is used to identify, profile or follow you, nothing is combined with other sources, and nothing is sold or shared for marketing.
The legal basis is our legitimate interest in operating and securing the website, under Article 6(1)(f) GDPR. Because we keep no logs of our own, there is normally nothing on record here about your visit at all.
Cookies and browser storage
There are none. The site stores nothing in your browser: no cookies, no local storage, no fingerprinting. That is why you are not asked to accept anything โ there is nothing to consent to and nothing to opt out of.
Video and music
The project videos and the optional background music are files on our own server. Nothing is embedded from YouTube, Vimeo, Spotify or any other platform, so no third party is told that you were here. Media is downloaded only when you play it or hover a card preview, and never plays with sound unless you ask it to.
If you email us
If you write to hello@testgrond.nl we process your address, your message and any attachment in order to answer you โ under Article 6(1)(f) GDPR, or Article 6(1)(b) where the exchange concerns a possible agreement between us. We keep correspondence as long as it is useful for that conversation, and longer only where Dutch tax or administrative law requires it.
Who else is involved
The site runs on a virtual server rented from Hetzner Online GmbH in Falkenstein, Germany, which processes hosting data on our behalf. Our email and our domain run on TransIP B.V. in Leiden, the Netherlands, on the same basis. Both are inside the European Economic Area, so your data is not transferred out of the EEA. We use no analytics, advertising, tag management, A/B testing or profiling services of any kind.
Your rights
You may ask us for access to the personal data we hold about you and for its correction, deletion or restriction; you may object to processing based on legitimate interest; and you may ask for a copy in a portable form. Email us and we will respond within one month. In practice we normally hold nothing that identifies you, so the honest answer to most requests is that there is nothing to produce.
If you are not satisfied, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
Security
The site is served over HTTPS only, with strict transport security and a content security policy that forbids third-party scripts. Administrative access to the server is limited to the owner and requires a key. No arrangement is perfect, but there is also very little here to lose.
Children
This site is not aimed at children, and it asks nobody of any age for personal data.
Changes
If this policy changes, the date at the top of the page changes with it. There is no mailing list, so there is no notification to send.
