This page describes the accessibility of the Tosa Testing Platform and outlines our current level of conformance with applicable web accessibility standards.
What is digital accessibility?
Digital accessibility means designing and building websites and applications so that everyone can use them, including people with visual, motor, auditory, cognitive, or other disabilities.
For example, an accessible website allows users to:
- Customize the display using their browser or operating system (adjust font size, change colors, disable animations, etc.)
- Navigate using assistive technologies such as screen readers or keyboard-only navigation
- Access video and audio content with transcripts, captions, or audio descriptions
- Use the site on any device orientation or screen size without loss of functionality
Accessibility policy
Isograd is committed to making the Tosa Testing Platform accessible to all users, in accordance with the Web Content Accessibility Guidelines (WCAG) 2.2.
