Cookie policy
2026-09-04
This page lists the cookies and similar technologies (localStorage) used on the site. Under PECR and the UK GDPR we ask for your consent before anything non-essential is stored on your device, and nothing non-essential loads until you give it.
What we use
“theme” (localStorage, functional) - remembers the light or dark theme you picked; kept until you clear it.
“cookie-consent” (localStorage, functional) - remembers your consent choice; kept for up to 12 months.
The build you are working on is kept in your browser and passed in the link parameters (?b=...), not in a cookie.
Advertising cookies (Google AdSense) - set only after you choose “Accept all”. Google may use cookies to personalise ads; more at policies.google.com/technologies/ads.
Site analytics (Vercel Web Analytics) - cookieless, so it stores nothing on your device, and it still loads only after you choose “Accept all”. We set no analytics cookies.
How to manage them
You can withdraw consent at any time by clearing your browser data (localStorage) or by changing your choice when the banner appears again. You can also block cookies in your browser settings.
