Calculator and report data

Handarm’s calculator runs in your browser. The application does not send operative names, site names, supervisor names or report contents to a Handarm report database. Daily report drafts are stored in this browser’s local storage and remain until you clear them or remove site data. Calculator drafts use session storage and are restored only for the same calendar day.

Anyone using the same browser profile on this device may be able to see saved reports. Avoid entering names on shared devices unless appropriate safeguards are in place. Changing browser, device or website address does not transfer these drafts.

Clearing and exporting your information

Use “Clear this date’s report” to remove a saved daily report. Reset clears the current calculator; it does not remove saved reports. Your browser’s site-data settings can remove all local Handarm data. Printed sheets and exported PDFs are separate copies under your control: store, share and dispose of them according to your organisation’s requirements.

Website services and external links

The website is delivered using OpenAI Sites and Cloudflare infrastructure. Hosting providers may process technical request information such as IP address, browser details and requested URLs for delivery, security and operation. Handarm’s application code does not add advertising or analytics trackers. Google Fonts supplies the typefaces and receives normal web requests when they load.

Links from a tool page into the calculator can include the selected tool, magnitude and time in the URL; avoid sharing such links if those values are confidential. Manufacturer and HSE links open external websites governed by their own policies. OpenAI privacy policy · Cloudflare privacy policy · Google privacy policy.
