Built to be used, not just looked at.

The standard we aim at

OLTRX aims to conform to the Web Content Accessibility Guidelines version 2.1 at Level AA, the standard referenced by EN 301 549 in Europe and used as the benchmark for the Americans with Disabilities Act in the United States.

We believe this site is substantially conformant, meaning it meets the standard with the exceptions listed below. This is our own assessment, not a third-party audit.

What we did

• Keyboard. Every link, button, field and control is reachable and operable with a keyboard alone, in a sensible order, with a visible focus outline. A skip link is the first stop on every page.
• Contrast. Every text style on every page was measured against the surface behind it. All pass 4.5:1, with the lowest at 4.8:1. Form borders meet 3:1 for control boundaries.
• Motion. The moving mark respects your operating system’s reduced-motion setting. Because that setting is not a control on the page, there is also a Pause motion button in the footer that stops it outright.
• Structure. One h1 per page, headings in order, real landmarks, and labelled navigation. The decorative mark is hidden from screen readers so it is never announced as noise.
• Forms. Every field has a visible label tied to it, required fields are marked in text as well as color, and hints are linked so a screen reader reads them with the field.
• Colour. Colour is never the only way information is conveyed. Where a category is color-coded, it is also named in words.
• Text. Nothing is text baked into an image, so everything reflows and rescales. The site works at 200% zoom and at 320px wide.

Known limitations

Being honest about these is more useful than claiming perfection.

• The code sample on the homepage is read out character by character in some screen readers, as code tends to be. It is illustrative; nothing on the site depends on understanding it.
• The animated mark is decorative and hidden from assistive technology, so screen reader users get no description of it. We think a description would be noise rather than information, but tell us if you disagree.
• The mark passes behind text in places, and on a phone it sits behind the copy as a faint backdrop. Text contrast is measured against the page, not against the mark, so a moment of reduced legibility is possible as it drifts. Pressing Pause motion stops it where it is, and your reduced-motion setting does the same automatically.
• The pause-motion setting does not persist between pages. Making it persist would mean storing something on your device, which this site deliberately never does. Your operating system’s reduced-motion setting does persist and is respected everywhere.
• No third-party audit has been carried out, and we have not tested with every screen reader and browser combination.

Legal position

The European Accessibility Act has applied to consumer-facing digital services since 28 June 2025. It exempts microenterprises (fewer than 10 staff and turnover at or below €2 million) from its service requirements. We may fall within that exemption. We are building to the standard regardless, because the exemption disappears the moment we grow, and because it is the right way to build.

If something blocks you

Tell us and we will fix it. Email hello@oltrx.io with the page, what you were trying to do, and what got in the way. Mentioning your browser and any assistive technology helps, but is not required.

We acknowledge within 2 business days and aim to resolve or give you a timetable within 10 business days. If you need something on this site in a different format, ask and we will provide it.

If you are not satisfied with our response, you can raise it with the accessibility enforcement body in your country. In the EU each member state designates one under the European Accessibility Act; in the UK it is the Equality Advisory and Support Service.
