Privacy
This page is short because the honest answer is short: this site collects nothing about you.
What the site does not do
- No cookies — first-party or otherwise. Nothing is stored on your device by this site.
- No analytics or tracking — no measurement scripts, no pixels, no fingerprinting.
- No forms or accounts — there is nothing to sign up for and nowhere to submit anything.
- No third-party resources at runtime — fonts, styles, scripts and images are all served with the site itself, so no other company observes your visit through this site.
- No advertising — and no advertising networks.
The calculators run in your browser
Every value you type into a planning sheet is processed by JavaScript running locally in your browser. Calculator inputs are not transmitted anywhere, not stored between visits, and cease to exist when you close the page. Printing a plan record uses your browser’s print function; the resulting document exists only where you choose to save it.
Ordinary web-server logs
Like effectively every website, the server that delivers these pages may keep standard technical logs (requested URL, timestamp, IP address, user-agent) for security and operations. Such logs are not used by this site to identify or profile visitors, and the site adds no identifiers of its own to them.
External links
Citation links — to HSE, legislation.gov.uk and manufacturer documents — leave this site, and those publishers’ own privacy practices apply from the moment you follow one.
This statement describes the site as built under content contract 2026-08-20.2. If the site’s behaviour ever changes, this page changes with it, and the change is recorded on the methodology sheet.
