What you're embedding
A minimal, self-contained hydration calculator — a bodyweight-scaled baseline plus a training-day addition — no ads, no analytics, no tracking, no webfont download. It uses the same pure calculation code as the full water intake calculator page on this site, so the numbers your visitors see match ours exactly.
