Privacy Policy

No uploads: all calculations — unit conversions, comparisons, the planets tool — run entirely in your browser. Weights you type, including your own weight, are never sent to any server.

Local storage: the site stores at most two small preferences on your device, using keys prefixed hh.: hh.unit (your preferred display unit) and hh.recent (your last few comparison setups, so the tool can restore them). This is not a tracking technology, it never leaves your device, and the comparison page has a “clear my preferences” button that removes both keys.

No accounts, no tracking cookies, no advertising scripts, no analytics as of the last review of this page.

Hosting: the site is served as static files. Our host (Cloudflare) may keep standard, minimal server logs as part of delivering pages, like most websites.

If we ever add analytics or advertising, we will update this page first and say plainly what changed.
