Accessibility

FirstSignal is designed to be usable by everyone who follows security, whatever their eyesight, dexterity or phone settings.

Last reviewed: 10 November 2026

Our standard

We design and test the app and this website against the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA, and against the accessibility guidance Android publishes for apps.

In the app

• Text is set in Atkinson Hyperlegible Next and Mono, typefaces designed for legibility under low vision, with a slashed zero and distinct I, l and 1.
• Large text: screens adapt to Android font sizes up to 200%, in Dark and Light mode. At large sizes labels wrap instead of being cut off, and dense rows reflow.
• TalkBack: controls have spoken names. Screen titles, sections and lanes are headings, and every swipe action is also available as a TalkBack action.
• Touch targets are designed at 48 dp, so controls are easy to reach.
• Lanes are told apart by shape and word, not by colour alone, so they read in greyscale and with colour blindness. Text colours meet WCAG AA contrast in both themes.

On this website

• Plain HTML with headings, landmarks and a skip link; no scripts.
• Light and dark themes follow your device setting, and text colours meet WCAG 2.2 AA contrast.
• Pages reflow from 320 px wide and at 200% zoom, follow your text size, and respect reduced motion and increased contrast settings.
• Keyboard focus is always visible, and every screenshot has a text description.

How we test

Automated accessibility checks run on every build of the app. They cover spoken names for controls, touch target size and layout at large text sizes. Accessibility is reviewed with each release, and we act on the reports we receive from people who use assistive technology.

Report a barrier

If something in the app or on this site is hard to use, email support@firstsignalcyber.com with the screen, your phone and the setting you use (for example TalkBack or a large font size).
