Cookie statement

This statement explains which cookies and similar technologies this website uses, what for, how long they remain and how to change your choice.

In short: without your consent, this website sets no cookies at all. Only if you allow analytics does Google Analytics set two cookies. We use no advertising, marketing or social media cookies. If the Dutch and English versions differ, the Dutch version prevails.

1. What cookies and similar technologies are

A cookie is a small text file that a website stores on your device through your browser. Your browser's local storage (localStorage) works in a similar way. Where we write 'cookies', we include such similar technologies.

Section 11.7a of the Dutch Telecommunications Act provides that a website may only store or read information on your device with your consent, unless this is strictly necessary for the service you request. Where cookies involve personal data, the GDPR also applies; see the privacy statement.

Google's cookies are only set after you click 'Allow analytics'. If you decline, Google's script is not loaded.

The fonts on this website are served from our own server; no request is made to Google Fonts. We use no embedded videos, maps, chat widgets, social media buttons or advertising networks.

How we configured Google Analytics is described in section 6 of the privacy statement.

In addition, this website measures visitor numbers with Vercel Web Analytics. This happens without cookies and without any other storage on your device; a visit is recognised by a temporary, irreversibly converted code (a hash) that expires after 24 hours. Nothing is stored on your device and we only see aggregated figures, not individual visitors. We therefore do not ask for consent: this is a measurement with no or minor impact on your privacy (Section 11.7a(3) Dutch Telecommunications Act).

3. Changing or withdrawing your choice

You can change your choice at any time via 'Cookie settings' at the bottom of every page. If you withdraw consent, measurement stops immediately and the website removes the Google Analytics cookies.

You can also block or delete cookies in your browser settings, for example in Chrome, Safari, Firefox and Edge. The website still works if you block all cookies.

4. Questions and changes

Questions about cookies can be sent to info@rezahealthandperformance.nl. If we start using other cookies, we will update this statement and, where required, ask for your consent again.
