Accessibility Statement

Last updated: 2026-05-17.

Brightscale Labs Limited is committed to making FitMetricLab usable for as many people as possible, including those who rely on assistive technology. This statement describes our current conformance, known issues, and how to report problems.

Conformance status

FitMetricLab aims for WCAG 2.1 Level AA conformance. Calculators are built as static HTML forms first, with progressive enhancement — page layout, navigation, and content reading work without JavaScript, though performing a calculation requires JavaScript to be enabled.

We test pages with keyboard navigation, sufficient colour contrast, semantic headings, and labelled form controls. Each calculator input has an associated visible label and an HTML label association rather than placeholder-only labelling.

Technical specifications

Accessibility of FitMetricLab relies on the following technologies working with the combination of web browser and any assistive technology installed on your device:

• HTML5 (semantic landmarks: header, main, nav, footer, article)
• WAI-ARIA where native semantics fall short
• CSS for visual presentation (the site is usable with CSS disabled)
• JavaScript for live calculation (page reading and navigation work without it)

Compatibility

The site is designed to be compatible with the following assistive technologies on current operating systems:

• Screen readers: NVDA and JAWS on Windows, VoiceOver on macOS and iOS, TalkBack on Android.
• Browsers: the latest two versions of Chrome, Firefox, Safari, and Edge.
• Zoom: works at 200% zoom without horizontal scrolling on a standard 1280-wide viewport.
• Reduced motion: animations respect the prefers-reduced-motion media query.
• Colour scheme: light and dark themes available; theme respects prefers-color-scheme and a manual toggle.

Known issues

We track accessibility gaps openly. Current known issues:

• Live region announcements: the calculator result region updates live as you change inputs, but does not always emit an aria-live announcement to screen readers. Result text is focusable and labelled so it can be navigated to manually. Live-region polite announcements are on the shortlist.
• Slider keyboard control: some compound input controls (number plus slider pairs) currently expose only the number input to keyboard users. The slider is decorative-equivalent — keyboard users can adjust values via the number input without loss of function.
• Charts: where a tool renders a small visualisation, the underlying data is also shown numerically so the chart is not a sole-source of information.

Assessment approach

Brightscale Labs Limited assessed FitMetricLab against WCAG 2.1 AA using a combination of automated audit tools (Lighthouse, axe-core), manual keyboard walkthroughs, and screen-reader spot-checks. We do not currently hold a third-party accessibility certification; if and when we commission one, this statement will be updated to reflect the result.

Feedback and contact

If you encounter an accessibility barrier on FitMetricLab, please tell us. Email contact@brightscalelabs.com with the page URL, the browser and assistive technology you were using, and a brief description of the problem. We aim to respond within 5 working days and to confirm a fix timeline.

Enforcement procedure

In the United Kingdom, the Equality and Human Rights Commission (EHRC) is responsible for enforcing the Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018 and the Equality Act 2010. If you are not satisfied with how we respond to an accessibility complaint, you can contact the Equality Advisory and Support Service (EASS). In the European Union, contact your national supervisory authority for the EU Web Accessibility Directive.
