Accessibility statement

For Polarity Profiler (lsr-profiler.org)

Phronon is committed to making its websites accessible in accordance with the Web Content Accessibility Guidelines (WCAG) 2.2, level AA (the standard behind EN 301 549 and Directive (EU) 2016/2102). This accessibility statement applies to Polarity Profiler, including its participant pages and the educator backoffice.

Measures to support accessibility

• Automated WCAG 2.2 AA checks run on every deployment against a sample of pages — the home page, the “about” page and the sign-in page — and a release is blocked if they find an error. They currently report zero errors and zero warnings on those pages. Pages reached only after signing in, and pages inside an exercise, are not covered by that automated run; they have been reviewed by hand only. Separately, every deployment does check all templates for two specific faults fleet-wide: markup that breaks a page's structure, and event handlers the site's security policy would silently disable.
• Every drag-and-drop interaction has a full keyboard alternative, with visible focus and screen-reader announcements. The participant flows and the main backoffice screens have been walked through with a keyboard by hand; that is a developer check, not a formal keyboard-only audit.
• Every image carries a text alternative, and the automated checks block a release if one is missing. Decorative images are marked so screen readers skip them. Every results chart carries a text label naming what it shows, and the figures behind it are published as a data table on the same page, opened from the “Data table” control beneath the chart.
• Pages use semantic landmarks, labelled form fields, sufficient colour contrast, a visible skip link to the main content, and error and status messages that are announced to assistive technology.
• Pages are built to reflow at 200% zoom and respect the operating system's reduced-motion setting, and impose no time limits on participants during an exercise. The zoom and contrast behaviour is designed in and spot-checked, not measured by a formal audit.
• Signing in works with password managers and does not block pasting. Two-factor codes use the standard one-time-code field, and recovery codes provide an alternative path (WCAG 3.3.8, accessible authentication).
• There is no audio or video content, so captions and audio descriptions are not applicable.

Compliance status

This website is partially compliant with WCAG 2.2 level AA, due to the non-compliances listed below.

Non-accessible content

The content listed below is non-accessible for the following reasons (non-compliance with the accessibility requirements):

• Some action buttons in dense educator tables may fall below the minimum target size of WCAG 2.5.8.
• The assessment behind this statement is automated and internal. A manual audit with assistive technologies (screen readers, voice control) has not been carried out, and none is currently scheduled — so barriers that only such an audit would reveal may exist.

Preparation of this accessibility statement

This statement was prepared on 30 July 2026. It is based on a self-assessment: automated testing of a sample of public pages (home, about, sign-in), re-run on every deployment, and an internal review of the interactive components. It is not based on automated testing of the complete site, and not on any external audit. The statement was last reviewed on 1 August 2026.

Feedback and contact information

If anything on this site is hard to use with assistive technology, please tell us — we treat access barriers as defects and fix them with priority. Write to info@phronon.org and mention the page and the technology you were using. You can expect a reply within five working days.

Language of this statement

This statement is published in English only. That is a deliberate decision and applies across all Phronon tools, including those whose participant pages are available in other languages: the statement is kept in one language so that it stays accurate about what has actually been tested. The legally required notices — the Impressum and the privacy and cookie notices — are translated wherever the tool's participant pages are.

Enforcement procedure

Phronon is a private provider, so the enforcement procedure of Directive (EU) 2016/2102 does not apply to this site directly. If you have reported a problem to us and are not satisfied with our response, you can escalate to the same address marked "accessibility — escalation" and the matter will be reviewed by the owner personally. Participants using this site through a public-sector institution (for example, a university) may additionally contact that institution's accessibility officer or the enforcement body responsible for it under their national implementation of the Directive.
