Cookie Policy
Last updated: 2026-05-07 · Version 1.1
This Cookie Policy explains how Synthetix uses cookies, local storage, and similar technologies. Necessary storage supports the site; analytics and advertising storage are optional and stay denied until you choose to allow them.
What Are Cookies
Cookies are small text files stored on your device when you visit a website. They help us improve your browsing experience, analyze traffic, and deliver relevant content.
Types of Cookies We Use
We use necessary storage for site functionality, first-party consent storage, optional GA4 analytics, optional Google AdSense advertising storage, and cookieless Web Vitals reporting for performance diagnostics.
Managing Cookies
You can manage your choices through the cookie consent banner or the Cookie preferences button in the footer. Rejecting analytics or advertising prevents GA4 and AdSense from loading for ordinary readers.
