Accessibility Statement

1. Our commitment

Revizona is operated by Revizona Ltd. We want every student to be able to practise and revise on Revizona, whatever device they use and however they access the web.

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA across revizona.com, including the practice app and the blog. This is our target. We have not yet been independently audited, so we do not claim full conformance.

Under the Equality Act 2010, we make reasonable adjustments so that disabled users are not put at a substantial disadvantage. If something about Revizona makes it harder for you to use because of a disability, tell us and we will work with you to find a solution.

2. What we do now

When we build and update Revizona, we:

use semantic HTML, with proper headings, landmarks, lists and form labels, so screen readers and other assistive technology can understand the page structure;
check colour contrast so text and important controls meet AA contrast ratios in both light and dark themes, and we do not rely on colour alone to show meaning (for example, correct and incorrect answers are also marked with text or icons);
support keyboard access, so you can reach and use links, buttons, answer fields and menus without a mouse, with a visible focus indicator;
add text alternatives to images and diagrams, describing the information a student needs to answer the question;
let text resize, so pages remain usable when you zoom to 200% or increase your browser’s text size;
respect reduced motion, turning off non-essential animation when your device is set to reduce motion; and
design for small screens, so pages work at 390 pixels wide without sideways scrolling.

3. Known limitations

Complex diagrams. Some diagrams, such as circuit diagrams, graphs and biological structures, are detailed SVG images. Our text alternatives may not capture every detail a sighted student could see. If a description is not enough to answer a question, please tell us.
Mathematical notation. Equations and formulae may not always be read out clearly by every screen reader. We are working to improve how maths is presented to assistive technology.
The app is still in development. New screens may have issues we have not yet found, and we test as we go.

We are working to fix these. If one of them stops you using Revizona, contact us and we will try to help in another way.

4. Reporting a problem or asking for another format

If you find a barrier, or you need information from Revizona in a different format (for example, a text description of a diagram or a plain-text version of a page), please email [email protected]. It helps if you tell us:

the page address (URL) or question ID;
what you were trying to do and what went wrong; and
the device, browser and any assistive technology you use.

We will reply within 5 working days. Where we can, we will fix the issue or provide the information in a format that works for you. If you are not happy with our response, you can use our complaints process.

5. How we assessed this

This statement was last reviewed on 23 October 2026. The assessment was a self-assessment by our team, supported by automated checks. Our blog pages scored 100 in the Lighthouse accessibility audit when we tested them [CONFIRM: re-test before launch]. Automated checks only find some kinds of problems, so this score is not a certification and does not mean every page is fully accessible.

We will review this statement at least once a year and when we make significant changes to the site.
