Update cadence
The widget revalidates every 10 minutes via the Vercel CDN, so a returning visitor will see fresh numbers without ever hitting our origin.
Attribution
The widget links to hantacount.com inline. No additional attribution required. Credit elsewhere on the page is welcome but not mandatory.
Customisation
Swap ?theme=light for the light variant. For deeper customisation, fetch /api/cases and render your own UI.
Privacy
Cookieless. We do not track readers of embedded widgets. No third-party requests beyond the iframe itself.
