Cookie Policy

Last updated: 31 October 2026

Cookies are small files stored in your browser. GuestBusters uses the ones the site needs to work and, only if you agree, analytics and marketing cookies. Welcome books and guest forms use no analytics or marketing cookies.

Cookies and technologies we use

  • Necessary (always on): sign-in session (authjs.*, sb-*), your language and your cookie choice (stored in the browser). The site does not work without them.
  • Cookieless statistics: Vercel Web Analytics counts visits in aggregate, without cookies and without identifying visitors.
  • Analytics (with consent): Google Analytics 4 (_ga, _ga_*), up to 2 years. Shows which pages are viewed and where visits come from.
  • Marketing (with consent): Meta Pixel (_fbp, _fbc), up to 90 days. Measures sign-ups that come from Facebook and Instagram ads.

Managing your choice

On your first visit you can accept, reject or choose by category. Reject is as prominent as accept and the site works the same either way. You can change your mind at any time with the “Cookie preferences” link in the footer, or delete cookies in your browser settings.
