Accessibility Statement

Date last updated: 6th June 2024

This accessibility statement applies to the YUDU and Sentinel apps and websites owned by YUDU Ltd (YUDU Platforms) . YUDU’s clients may use the YUDU platforms for publishing their own content which should be designed and made to conform to accessible standards. Client content is out of scope of this statement.

Our Commitment to Accessibility

We are committed to ensuring digital accessibility for people with disabilities. We are continually improving the user experience for everyone and applying the relevant accessibility standards. This means you should be able to:

  • Change colours, contrast levels, and fonts using browser functionality.
  • Zoom in up to 400% without the text spilling off the screen.
  • Navigate most of the YUDU Platforms using just a keyboard.
  • Navigate most of the YUDU Platforms using speech recognition software.
  • Interact with most of the YUDU Platforms using a screen reader.

We also strive to make the YUDU Platforms text instructions as simple as possible to understand.

How Accessible YUDU’s Platforms are

We know from several accessibility reports that parts of YUDU’s Platforms are not fully accessible. This includes:

Fixed layout representations of content (print-like)

The proprietary reader software that reproduces print-like layouts used in YUDU apps and web reading is not accessible to screen readers, due to its reproduction necessarily having complex layouts that do not work well for this purpose.

YUDU does however, have features to create fully accessible standard HTML modes for publishers, accessed by end-users either from the toolbar of the fixed-layout version or via direct URL to this version. This version is compatible with screen readers and standard accessibility technologies and is often the preferred version for mobile devices like phones, where responsive content with dynamic text sizes is often far better for all users.

Publishers may produce the content for version themselves (using standard HTML tooling), or may have YUDU create it for them as a bespoke service.


In addition to web-based reading solutions, YUDU also provides publishers with App solutions for iOS and Android.

While iOS and Android do natively have their own accessibility technologies (for example VoiceOver on iOS for visually impaired or blind users) and the Apps are accessible by those, YUDU is currently implementing a much more thorough development upgrade for our iOS and Android apps to support even more of those accessibility options (as of June 2024).

These include supporting Dynamic Type where possible (allowing end-users to adapt font sizes in user interfaces to the size they prefer), reworking user interfaces to make navigation flow better for users using accessibility technologies and running through thorough audits of each screen in our apps.

Technical Information about YUDU’s platform accessibility

We're committed to making YUDU platforms accessible, in accordance with the accessibility regulations.

Compliance Status

YUDU’s Platforms are partially compliant with the Web Content Accessibility Guidelines (WCAG) version 2.1 AA standard, due to the non-compliances listed below.

Non-Compliance with the Accessibility Regulations

Fixed-layout print representations are by their nature, not accessible (and why we provide alternative accessible solutions).

What We're Doing to Improve Accessibility

We design our software and platforms to (WCAG) version 2.1 AA standards and our development team are testing compliance on each release. The client content must be to the same accessibility standards in order for the end user experience to be fully accessible. The client feedback we receive helps our teams build products and services to meet the best accessibility standards.

At YUDU, creating an accessible service is a team effort. We want our teams to make accessible services by:

  • Considering accessibility at the start of their project, and throughout.
  • Making accessibility the whole team's responsibility.
  • Carrying out quarterly accessibility audits and testing.
  • Designing and building to level AA of WCAG 2.1.

As part of this commitment, we have set up a cross-functional accessibility working group to make sure that accessibility remains at the core of everything we do.

We are making sure that accessibility issues highlighted in this statement are being prioritised and fixed.

Preparation of This Accessibility Statement

This statement was updated in June 2024.

The YUDU Platforms are tested quarterly using specialised web based tools such as the QualWeb accessibility checker (available at:, designed to check against level A and AA success criteria of WCAG 2.1.

When assessing Apps, YUDU uses tools such as Apple’s Xcode accessibility inspector (which audits each screen of the App for accessibility issues and suggestions) and similar.

Results are assessed on a priority basis and remediated as part of our standard development process.
