We do not sell your personal information to third parties.

Some of these providers are based in the United States. Where personal data is transferred outside the European Economic Area, this happens on the basis of the EU-U.S. Data Privacy Framework or the European Commission's standard contractual clauses.

  • Data portability
  • Withdraw consent at any time

To exercise these rights, contact us at privacy@mmre.nl.

8. Cookies and Advertising Measurement

When you first visit our website, we ask which cookies you accept. Necessary cookies are always on. Analytics and marketing cookies are only used after you consent, and you can change or withdraw your choice at any time via "Cookie settings" at the bottom of every page.

  • Necessary: required for the website to work, such as your language, your session and your cookie choice (mmre_consent, kept for 6 months).
  • Analytics (Google Analytics): helps us understand how visitors use our website, so we can improve it.
  • Marketing (Google Ads, Meta and OpenAI): lets us measure which adverts lead to an enquiry or a paid start package, so we do not spend budget on adverts that do not work.

OpenAI Ads (adverts in ChatGPT)

We may advertise in ChatGPT. With your consent for marketing cookies, we use the OpenAI measurement pixel and OpenAI's Conversions API to see whether a visit from such an advert leads to an enquiry or a paid start package. For this purpose:

  • the pixel sets two first-party cookies on our domain: __oppref (the advert click reference, 30 days) and __obref (a random browser reference, 365 days);
  • when you submit an enquiry or pay the start package, we send OpenAI the type of event (and, for a payment, the amount), the page, your IP address and browser type, and your e-mail address and phone number in hashed (SHA-256) form, so the event can be matched to an advert;
  • OpenAI uses this data to report and optimise our advertising. According to OpenAI, it is currently not used to personalise ChatGPT for you.

Without marketing consent, the OpenAI pixel is not loaded and no data is sent to OpenAI. If you withdraw consent, we stop sending data and remove these cookies. The legal basis is your consent (Article 6(1)(a) GDPR). More information is available in OpenAI's privacy policy at openai.com/policies.

9. Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction.
