All the Kitaboo apps are WCAG 2.1 compliant. WCAG guidelines were created to make website content accessible to people with disabilities. The major problem is there are no conclusive documents as to what makes a website 100% accessible.
So, the recommended way to get your accessibility certification is by seeking the help of WCAG audit services to audit your website for accessibility and remediate the issues.
Once the issues are fixed, a re-audit will be performed, and you can get your WCAG compliance claims.
