Accessibility Statement
VISIBILITYOS NETWORK LTD wants every calculator on CalculatorFox to be usable by everyone, including people who use a keyboard only, a screen reader, magnification or high-contrast settings. We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA.
What we have done
Every input has a visible label and help text; results and error messages are announced to assistive technology as they change; pages can be operated entirely from the keyboard, with a visible focus indicator and a skip link to the main content; the search box is a proper combobox with arrow-key navigation; colour is never the only carrier of meaning; text can be resized to 200% without loss; the site works without JavaScript, showing the answer for the default figures.
Known limitations
Some worked examples contain long formulas that screen readers read character by character. Charts on a few pages are drawn as images with a text description rather than a data table. Advertisements, where shown, are served by a third party and are outside our control.
Tell us about a barrier
If any part of the site is hard to use, email support@calculatorfox.org or use the contact form. We reply within five working days and fix what we can. This statement was last reviewed on 5 September 2026.
