Accessibility statement

Aster Disk is designed for showcase-grade accessibility, not just compliance. Every common task — scan a drive, browse what it found, unlock Pro, review suggestions, see what trophies you've earned — can be completed with VoiceOver, Voice Control, or the keyboard alone.

VoiceOver

Every interactive control has a label. The four visualisations — treemap, sunburst, bubble pack, horizontal bars — are layouts of the same data. For VoiceOver users, for whom layout carries no signal, they collapse to a single ordered list of folders by size, each with named actions for Open and Add to selection. The chart canvas itself is hidden from accessibility so it's never read as "image."

File-browser rows read as a single coherent sentence, e.g. "Library, 32.1 GB, 31.7% of folder, directory. Double-tap to open. Press the plus button to add to selection." Percentages are rendered through a locale-aware number formatter, so French VoiceOver hears "31,7 %", not "31.7%."

Trophy badges read as "Snack, unlocked. Reclaimed 100 MB lifetime." Locked trophies still read so VoiceOver users can discover what's possible.

Voice Control

Every named control responds to its visible label. Say "click Scan Whole Disk", "click Unlock", "open Settings". Sidebar destinations, Settings tabs, Suggestion-card actions, paywall buttons, and Home action cards all carry stable identifiers so Voice Control can target them by name.

Keyboard

Tab cycles through interactive controls in visual order. ⌘O picks a folder, Return runs Scan Whole Disk from Home, Space previews the focused file via Quick Look, Esc stops a scan in progress.

System preferences respected

• Reduce Motion — onboarding petal pulse, Victory bloom rings, and chart drill-down animations skip to their final state.
• Reduce Transparency — vibrant surfaces (FDA banner, brand-bg cards) fall back to opaque brand colour.
• Increased Contrast — hairline borders deepen, ink-2 / ink-3 distinction widens, safety-tinted card outlines thicken.
• Dynamic Type — text sizes in the sidebar, action cards, paywall, and suggestions panel scale with your preferred reading size.
• Differentiate Without Color — safety semantics ship icon + label, not just colour. Trophy locked/unlocked reads as text.
• Dark Mode — every theme token resolves per colorScheme.

These are reflected live in Aster Disk's own Settings → Accessibility tab, so users can see at a glance what the app is doing for them right now.

What's not there yet

Honesty about what we haven't shipped is part of an accessibility statement. Open items at the time of writing:

• A full Dynamic Type sweep across the ~80 fixed font sizes is in progress; macOS's text-scaling story is less granular than iOS's, so per-app preferred reading size still maps to a subset of the design tokens.
• Captions and audio descriptions don't apply — Aster Disk has no media content.
• VoiceOver copy polish (Markdown asterisks in rare body strings, decimal separators in non-English locales) was audited in May 2026; future regressions are checked by the screenshot capture pipeline.

Feedback

If something doesn't work, or works less well than it should, please tell me. The fastest path is to open an issue on GitHub; for private feedback, email accessibility@asterdisk.com. Accessibility regressions are treated as bugs, not "nice-to-fix-later."
