Accessibility Statement
Last updated July 13, 2026. CalcStack is built to be usable by everyone, including people who navigate by keyboard, use a screen reader, or need reduced motion. This statement explains what we do to meet WCAG 2.1 Level AA and how to tell us when we fall short.
Our commitment
CalcStack aims to meet WCAG 2.1 Level AA. Accessibility is a continuous effort rather than a one-time certification: we build to the standard, test against it, and treat any gap a real user hits as a bug to fix. This statement describes the measures in place today and how to reach us if something does not work for you.
Keyboard access
Every interactive tool on CalcStack is fully operable without a mouse. Answer choices can be selected with letter and number keys, Enter advances a step, and focus moves to the next question automatically so a keyboard or switch user never has to hunt for the active control. A skip-to-content link is the first focusable element on every page, and focus outlines stay visible rather than being suppressed.
Reduced motion
Step transitions, staggered reveals, and count-up animations are decorative, never load-bearing. When a visitor's operating system requests reduced motion, all of these are disabled and content appears immediately in its final state. This is enforced in our stylesheet and checked in our test suite, so a newly added animation cannot silently escape the guarantee.
Screen readers and semantics
Pages use semantic HTML landmarks and heading order so assistive technology can navigate by structure. Interactive controls carry accessible names, form fields are associated with their labels, and images that convey meaning carry descriptive alt text while purely decorative icons are hidden from the accessibility tree. Data visualizations render an accompanying screen-reader-only data table so the numbers are available without relying on the visual chart.
Visual design and targets
Text and interactive elements are designed to meet WCAG AA contrast, and the interface reflows to a 375px mobile viewport without horizontal scrolling. Tap targets are sized to a 44px minimum so they are usable with imprecise pointing or on a small screen, and text can be resized by the browser without breaking the layout.
Embedded tools on your site
The same access measures travel with the tools you embed. A calculator, scorecard, quiz, or grader placed on your website keeps its keyboard operation, reduced-motion support, visible focus, and screen-reader semantics inside the embed, so the experience you offer your own visitors is accessible by default rather than something you have to retrofit.
Ongoing work and known limits
We do not claim full conformance. Automated and manual checks cannot catch every issue, and some third-party content (such as an embedded scheduling widget a customer connects) is outside our direct control. Where we find a gap we prioritize it, and we welcome reports that point us at real problems faster than our own testing would.
Report an accessibility issue
If you encounter a barrier using CalcStack or a tool embedded with it, email accessibility@calcstack.net with the page or tool, what you were trying to do, and the assistive technology or settings you were using. We aim to acknowledge accessibility reports within five business days and will tell you our plan to address the issue.
