Accessibility Statement

Last updated: October 14, 2026

Our commitment

Optophone is designed to be usable by as many people as possible, including people who rely on assistive technology. We aim to align with the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA as applied to a native mobile application, and we treat accessibility as an ongoing effort rather than a one-time milestone.

Measures in the app today

  • Screen readers: Interactive controls expose semantic labels for TalkBack (Android) and VoiceOver (iOS); decorative visuals are excluded from the accessibility tree so they are not announced.
  • Reduced motion: The app honors the system "reduce motion" setting. Non-essential animation is minimized, and when reduce motion is enabled the generative visualizers are frozen to a single still image — they are drawn once and do not animate.
  • Seizure safety (photosensitivity): The generative visualizers are designed to avoid full-screen content that flashes more than three times per second, consistent with the general-flash guidance of WCAG 2.3.1. You can also disable all on-screen animation by selecting the "Lights Out" visualizer. A dedicated Photosensitivity & Health Warning is presented on first launch and is available any time in Settings.
  • Dynamic text size: The interface respects the system font-size / Dynamic Type setting, scaled up to 2× while keeping layouts readable.
  • Color and contrast: Every theme is designed for body-text contrast that meets WCAG AA. There are four colour themes, each available in light and dark, and each is first-class rather than auto-inverted; the app follows the system light/dark preference. When the system “increase contrast” accessibility setting is on, the app switches to a higher-contrast variant of your chosen theme whose body text meets WCAG AAA.
  • Touch targets: Interactive controls are sized for comfortable touch.
  • Right-to-left: The app fully supports right-to-left layout, including Arabic, with mirrored directional layout.
  • No required account: The core experience works without sign-in, reducing barriers to entry.

Known limitations

Accessibility is never "finished." Some areas — including the generative visualizers, which are inherently visual — may not be fully equivalent for all users, and some third-party components (for example, payment sheets provided by the platform) are outside our direct control. We prioritize fixes to the core listening, mixing, sleep, and settings flows.

Assessment approach

Accessibility is reviewed through a combination of automated checks in our development pipeline and manual review of the primary user flows. This statement reflects a self-assessment; it is not a third-party certification or a guarantee of conformance.

Feedback

If you encounter an accessibility barrier in Optophone, we want to hear about it and will make reasonable efforts to address it. Please contact support@optophone.app and describe the issue, the screen involved, and the assistive technology and device you were using. We aim to respond within a few business days.

Scope

This statement applies to the Optophone mobile application for iOS and Android. Optophone is an audio app for relaxation and entertainment only; it is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition.
