PRIVACY
Privacy & cookie statement: which data this website collects, why, who receives it and what your rights are. Last updated 3 November 2026.
Who we are
JDH Company in Rotterdam, the Netherlands, registered with the Dutch Chamber of Commerce (KVK) under number 82993394, is the controller for the personal data processed through this website. For questions about privacy, e-mail us at info [at] jdh-company.com.
What we collect, and why
- Contact form and e-mail. Your name, e-mail address, phone number (optional), subject and message, to answer your question and, if you wish, prepare a quote or assignment. Legal basis: steps taken at your request before a contract (art. 6(1)(b) GDPR) and our legitimate interest in answering questions (art. 6(1)(f) GDPR). Without a name, e-mail address and message we cannot reply; you can also e-mail us directly. If you accepted statistics, your message also says which button on the website brought you to the form.
- Website statistics, only with your consent. Google Analytics 4 records which pages you visit, which website referred you, how you use the site, your type of device and browser, and your approximate location (country and city, derived from your IP address; Google Analytics 4 does not store the IP address itself). This shows us which pages help visitors. Legal basis: your consent (art. 6(1)(a) GDPR), which you can withdraw at any time.
- Server logs. Our hosting provider records technical data on every visit (IP address, time, page requested and browser) to keep the website secure and available. Legal basis: legitimate interest (art. 6(1)(f) GDPR).
We use no advertising cookies, sell no data, and make no decisions based solely on automated processing or profiling.
Cookies and local storage
| Name | Party | Purpose | Lifetime | Consent |

Without your consent this website stores only the two functional items above. Google Analytics loads only after you press “Accept”. If you withdraw your consent, we remove the _ga cookies and site_cta_source. You can change your choice at any time with , also at the bottom of every page.
Who receives your data
We use these processors, each with a data processing agreement in their terms:
- Web3Forms (the contact form) receives the form's content and your IP address, checks it for spam and forwards it to us by e-mail. Web3Forms operates from India; there is no adequacy decision for that country, so the transfer relies on the European Commission's standard contractual clauses.
- Google (Google Analytics, only after your consent). Google Ireland Limited processes the statistics; data may go to the United States under the EU-US Data Privacy Framework and the standard contractual clauses.
- Microsoft (Microsoft 365) runs our e-mail, where messages from the form or by e-mail arrive.
- FastComet (hosting) stores the website and the server logs on servers in the United States, under the standard contractual clauses.
How long we keep data
- Messages from the form or by e-mail: up to one year after our last contact. If an assignment follows, we keep the correspondence for seven years, as Dutch tax law requires.
- Copy at Web3Forms: under Web3Forms' policy up to three years, unless we delete the submission sooner.
- Google Analytics: the cookies 90 days; the statistics per visitor 14 months.
- Server logs: no longer than needed for security and fixing faults.
Your rights
You have the right to access your data, have it corrected or erased, restrict its processing, object to the processing, and have your data transferred. You can withdraw your consent for statistics at any time with the cookie settings; this applies from that moment on.
To make a request, e-mail info [at] jdh-company.com. We reply within one month. If you are not satisfied with how we handle your data, you can complain to the Dutch Data Protection Authority, the Autoriteit Persoonsgegevens.
