Accessibility statement

We build silvra.net to the Web Content Accessibility Guidelines (WCAG) 2.2, conformance level AA. This statement covers silvra.net and all its pages; the Helix Explorer and outside services such as Google Play or GitHub are not part of it.

By our checks, silvra.net complies with WCAG 2.2 AA; we currently know of no deviation from level AA. If you find one, please report it — how is described below.

Among other things:

• A switch “Pause motion and live values” in the header stops every animation and every self-updating number; the operating system’s “reduce motion” setting is honoured as well.
• Everything can be reached by keyboard, focus is always visible and every page starts with a “Skip to content” link. On the home page, ← and → choose a sector.
• Text reaches a contrast ratio of at least 4.5:1, in the light and the dark theme.
• Status is never conveyed by colour alone, always with a symbol and a word as well.
• The encrypted-looking characters behind the home page and the messenger page are decoration and hidden from screen readers; what they show is said in the text.
• Every page is delivered as finished HTML and readable without JavaScript; headings, landmarks and language are marked up.
• Every page exists in German and in English, each at its own address. On a first visit the language follows your browser’s setting; the DE/EN switch in the header leads to the same page in the other language, without JavaScript too. Your browser remembers your choice if it allows local storage.
• The site can be zoomed to 400% and used down to 320 pixels wide without scrolling sideways.

Before releases we check every page in the light and dark theme, at desktop and phone width, with axe-core against WCAG 2.2 A and AA — including contrast and target size — and test keyboard operation, zoom up to 400% and the motion switch. Last check: 14 October 2026.

What goes beyond level AA or falls outside this statement:

• There is currently no content in Easy Read or in sign language.
• The Helix Explorer is a separate application with a very dense display; it is not covered by this statement.
