Offline Cache

Service Worker Cache

Caches this page itself plus all CDN resources so Calculator 2 fully works offline. Requires the sw.js service worker file alongside this HTML file. The cache now auto-refreshes itself every time you're online, so it won't go stale — but you can also trigger it manually below.

Service worker status: checking...

This also downloads and caches the Pareto AI model (~200–400MB) so the math assistant works offline too. Skip it below if you'd rather do that separately on Wi‑Fi.

Cached Resources

The following are cached for offline use (this page's own URL is always included automatically):

Pareto AI Model

The LFM2‑350M‑Math (q4f16) model is cached separately by Transformers.js in the browser's Cache Storage the first time it's loaded, and is then reused offline automatically — no re-download needed.
