Cookie policy

Last updated: 3 November 2026

What cookies are

Cookies are small files a website stores on your device. Some are needed for the site to work. Others help us understand how the site is used, and we only set those if you agree.

Your choice

On your first visit, a banner asks whether you accept analytics cookies. Until you accept, Google Analytics and HubSpot set no analytics cookies: the site runs Google Consent Mode with everything denied by default. You can change your choice at any time with the "Cookie settings" link at the bottom of every page.

Strictly necessary cookies

  • __hs_cookie_cat_pref (HubSpot): remembers the cookie categories you accepted. 6 months.
  • __hs_opt_out (HubSpot): remembers that you refused cookies, so we don't ask again. 6 months.
  • __hs_do_not_track (HubSpot): stops HubSpot tracking when you refuse it. 6 months.
  • __hs_initial_opt_in (HubSpot): keeps the banner from showing on every page. 7 days.
  • _cfuvid (our hosting network): protects the site against abusive traffic. End of your browsing session.

Analytics cookies, only with your consent

  • _ga and _ga_4XJHQM9XGR (Google Analytics 4): count visits and the pages viewed. 13 months.
  • __hstc (HubSpot): records your visits to the site. 6 months.
  • hubspotutk (HubSpot): links your visits to a form you submit, so we don't create duplicate contacts. 6 months.
  • __hssc (HubSpot): tracks the current visit. 30 minutes.
  • __hssrc (HubSpot): detects a new browser session. End of your browsing session.

Measurement without cookies

Plausible Analytics counts visits in aggregate without setting any cookie and without identifying you.

Embedded forms

Our HubSpot forms (Talk to an engineer, report downloads) are loaded from HubSpot and follow the choice you made in the banner.
