Cookie policy
We use the smallest set of cookies needed to operate the site, plus the cookies that our advertising partner uses to serve ads. This page lists every cookie category and what it does.
Strictly necessary cookies
Required for the site to function. Includes authentication tokens (so you stay signed in), CSRF protection, and basic preference storage (dark/light mode). These cannot be disabled without breaking the site.
Preference cookies
Remember your settings — theme, default test region, dashboard layout. Persistent, removed if you clear cookies.
Analytics cookies (first-party)
We use first-party analytics to understand which features are useful. No third-party trackers are loaded for analytics. You can opt out by enabling Do Not Track in your browser — we respect it.
Advertising cookies (Google AdSense)
Ad-supported areas of the site display ads via Google AdSense. AdSense uses its own cookies for ad personalization and frequency capping under Google's policies. EU/UK users see a consent banner; you can manage ad-personalization at Google Ad Settings. See our advertising disclosure.
How to disable cookies
Every major browser supports cookie controls in its settings. Blocking strictly necessary cookies will sign you out and may break diagnostic tools. Blocking advertising cookies reduces ad relevance but does not affect site functionality.
Updates
We update this policy when our cookie usage changes. The last-updated date is shown above.
