Accessibility statement

We aim for the platform to be accessible to the widest possible range of readers, in line with the requirements of WCAG 2.1, level AA.

What is provided: changing the text size with the A− and A+ buttons; keyboard navigation and a visible focus; a link to skip to the content; text descriptions of the images; an audio version of the analyses; printing and saving as PDF; reduced motion when the device is set that way.

Known limitations: the audio version uses the browser’s speech synthesis, so the availability and quality of a voice depend on the device; the book view with page-turning requires JavaScript, and without it the same text is shown as an ordinary page; the check was carried out with automated tools and with the keyboard, without testing with a screen reader on every device.

If you encounter a difficulty, write to us at lyudmil[@]nautilex.bg with the subject “Accessibility”. We will reply within 5 working days.

Date of last check: 1 October 2026.
