Accessibility

Last reviewed: 2 November 2026

We want everyone to be able to use Sumplify, including people who use screen readers, keyboard navigation, magnification or other assistive technology.

Our standard

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA. Every update to the site is checked automatically for accessibility errors before it is published, and new calculators and page types are also tested by hand with a keyboard and a screen reader.

Built-in settings

Select Accessibility at the top of any page to change:

Text size: 100%, 125%, 150% or 200%
Line spacing: normal or wide
Display: standard, high contrast, dark, inverted colours or greyscale
Link highlighting: underline and bold all links
Reduce motion: turn off transitions
Readable font: wider letter spacing for body text

Your choices are saved in your browser on this device only. The site also follows your device’s dark mode, high contrast and reduce-motion settings.

What we do on every page

Clear headings and page regions, and a “Skip to main content” link
Text and controls with enough colour contrast; colour is never the only way information is shown
Every feature works with a keyboard, with a visible focus indicator
Calculator fields have labels and instructions, errors are described in text, and results are announced to screen readers
Charts have text descriptions and an accessible data table
Pages work at 200% zoom and on narrow screens without sideways scrolling
No auto-playing media or flashing content, and no ads that cover the page

Known limitations

Advertisements are supplied by third parties. We place them in labelled areas that don’t block content, but we can’t fully control their content.

Report a problem

If something on the site is hard to use, please email hello@sumplify.app with the page address and what happened. Accessibility reports are handled with the same priority as error reports.
