Cookie policy

Cookies are small files a website stores in your browser. This site uses as few as possible, and only the necessary one is set before you choose.

Your choice

When you first visit, you choose which cookies we may use. Accepting and declining are equally easy, and declining does not limit the site. You can change your choice at any time through Cookie settings at the bottom of every page.

Cookies we use

Necessary

  • cc_cookie (DIJKAds): remembers your cookie choice. Kept for 6 months.

Analytics (only if you accept)

  • _ga and _ga_[ID] (Google Analytics): count visits and show how people use the site, so we can improve it. Kept for up to 2 years.

Marketing (only if you accept)

  • _gcl_au (Google Ads) and _fbp (Meta): measure whether our ads lead to visits and booked calls. Kept for 3 months.

Google Tag Manager, which loads these tools, is only downloaded after you accept analytics or marketing cookies. If you decline, we do not measure your visit at all.

Other services on the site

  • Booking calendar. The calendar on the book a call page comes from TidyCal and uses Google reCAPTCHA against spam. It loads without asking, because booking is what you came to that page for, and it may set its own cookies. See the privacy policies of TidyCal and Google.
  • Videos. Videos come from Vimeo and only load when you press play. They run in do-not-track mode.

Blocking cookies in your browser

You can also block or delete cookies in your browser settings. If you block the necessary cookie, the site will ask for your choice on every visit.
