Accessibility statement
Accessibility Sentinel, published by Crystal Trois (EURL), is committed to making its website accessible. This is a voluntary commitment: the site does not fall within the scope of the services covered by Article 47 of French law no. 2005-102 of 11 February 2005, nor of Directive (EU) 2019/882 (the European Accessibility Act), but we apply to our own site the same framework and method we use for our audits.
To that end, Accessibility Sentinel implements the following actions:
- a full audit of the site at every major change, using the audit platform we run for the lab programme;
- remediation of the non-conformities found, followed by a full verification re-audit;
- ongoing expansion of our audit chain's automated coverage, with the site re-measured at every method update (latest expansion: 15 July 2026 evening);
- publication of the results, including what is not conformant and what our tooling cannot yet decide.
This accessibility statement applies to accessibility-sentinel.com (as of 15 July 2026 evening, after the audit-coverage expansion).
Compliance status
The accessibility-sentinel.com website is in partial compliance with RGAA version 4.1.2: 97.2% of the criteria measured by our audit chain are compliant (35 compliant criteria, 1 non-compliant), and 21 criteria could not yet be verified automatically — we therefore do not claim full compliance. Version 4.1.2 is currently the applicable reference; see where RGAA version 5 stands, currently being drafted.
Test results
The compliance audit was carried out on 15 July 2026 by Accessibility Sentinel with its own audit platform (self-assessment — the same tool chain and evidence requirements applied to the sites audited under the lab programme). A first pass in the morning found 5 non-conformities; the fixes were deployed and then re-verified by a second full audit the same day. Later that evening, our audit chain's automated coverage was expanded to new semantic-relevance criteria (link wording, heading wording, content structuring) and the site was re-measured unchanged: 34 previously-undecided criteria received a verdict, including 1 real non-conformity previously invisible to our audit chain (see "Non-conformities" below). Every new finding coming from an automated judgment went through quality control before publication (cross-checked against independent deterministic measurements, judged material reviewed) — several initial findings turned out to be model judgment errors and were discarded after review, a transparency we stand behind in our method. The audit covers all 22 published pages (11 French + 11 English): exhaustive coverage, not a sample.
- 97.2% of the RGAA 4.1.2 criteria measured are met: 35 criteria compliant, 1 non-compliant, 49 not applicable to the site's content. The rate is computed at the level of the official RGAA unit tests, with not-applicable criteria excluded from the denominator. The mechanically proven rate (excluding all checks decided by a multimodal-model judgment) is 96.7%.
- 21 RGAA criteria remain undecided by our automated chain (37 before the coverage expansion on the evening of 15 July); they are counted neither compliant nor non-compliant. A manual verification protocol is documented for each of them in the audit report.
- Against WCAG 2.1/2.2 level AA (a distinct framework, assessed independently): 24 criteria compliant, 1 non-compliant, 14 not applicable, 17 undecided — AA conformance not claimed (1 known non-conformity, remaining criteria not yet verified).
Non-accessible content
Non-conformities
One known non-conformity, found on the evening of 15 July 2026, fix pending:
- Link not explicit out of context (RGAA 6.1.1,
WCAG 2.4.4) — the "Learn more" link in the cookie consent banner
(pointing to the Cookies page) is not understandable on its own, for
example when reached through a screen reader's list of links. Planned
fix: add a more explicit accessible name (e.g.
aria-label="Learn more about our cookie policy").
No other known non-conformity on the measured criteria.
Fixes applied on the morning of 15 July 2026 (each verified by re-audit)
- contrast of the statistics-card link: 1.24:1 → 13.09:1, with underline added;
- contact-form field borders: ~1.5:1 → 3.45:1;
- a site map was added (FR and EN), linked from the footer of every page — the site now offers two navigation systems;
- clickable targets brought to at least 24×24 px (footer links in particular);
- focus masking by the cookie banner (WCAG 2.4.11): fixed and re-verified in first-visit state (banner displayed) — the focused element is now brought out of the banner's area, and the banner sits at the start of the tab order; no overlap measured across ~35 keyboard stops per tested page.
Exemptions for disproportionate burden
None.
Content not within the scope of this statement
Third-party services linked from the site (calendar.google.com booking, the external cnil.fr and ovh.com websites) are not covered by this statement.
Action plan
- fix the "Learn more" link in the cookie banner (explicit accessible name) and re-verify;
- manually verify the 21 RGAA criteria (and 17 WCAG criteria) not yet decided automatically, following the protocols documented in the audit report — including, in part, script restitution by screen reader and the full tab order;
- keep expanding automated coverage on the remaining semantic-judgment criteria;
- fully re-audit the site at the next major change.
Preparation of this accessibility statement
This statement was prepared on 15 July 2026 (updated the same day after the audit-coverage expansion).
Technologies used to build the site
- HTML5;
- CSS;
- JavaScript.
Test environment
Content rendering was verified with the NVDA screen reader (actually captured speech output) combined with a Chromium browser on Windows 11.
Tools used to assess accessibility
- axe-core 4.9.1 run in a real browser;
- W3C HTML validator (Nu Html Checker), local instance;
- an automated in-browser test battery: independent contrast computations (including UI components), geometric measurements (touch targets, label position), focus visibility and masking (including in first-visit state, cookie banner displayed, and when modal dialogs close), 200% text zoom, text spacing, forced colours, keyboard navigation, reading order with CSS disabled, pages without JavaScript, page-element inventory (structure, presentation, gestures);
- NVDA screen reader with an element-by-element cross-check between the computed accessible name and the speech actually announced;
- a real session-timeout test: form left idle for 30 minutes with checks every 5 minutes;
- multimodal vision-model-assisted judgments (relevance of decorative images, text alternatives, link and heading wording, information conveyed by colour or shape alone), always retained with their evidence, cross-checked against independent deterministic measurements where available, and human spot-checked before publication; their share is isolated in the "mechanically proven" rate.
