Accessibility Statement

Last updated: 28 April 2026

Brightscale Labs Limited is committed to making BuildMetricLab

accessible to people with disabilities. We aim to conform to the

Web Content Accessibility Guidelines (WCAG) 2.2 Level AA, which

is the standard referenced by **Title III of the Americans with

Disabilities Act (ADA)** as applied to public-facing websites and

by Section 508 of the Rehabilitation Act for federal-government

contexts.

What is accessible

• Every calculator works with keyboard only (Tab, Enter, arrow keys).
• Form inputs use labelled controls with associated hints.
• Color is not the only means of conveying information.
• Text contrast meets 4.5:1 for body copy and 3:1 for large text.
• Pages are semantic HTML with a single `<h1>` and logical heading order.
• Dark mode respects `prefers-color-scheme` and can be toggled manually.
• Content is readable at 200% zoom without horizontal scroll at a

375px viewport width.

• Touch targets meet a minimum 44×44 CSS-pixel size.

Known issues

We track accessibility issues alongside other bugs. If you hit a

barrier, please email [email protected] describing the

page and what did not work — we aim to fix access issues within

five business days.

Third-party content

Where we embed third-party widgets (if any) those may have

independent accessibility obligations. We avoid them wherever

possible.
