SPP Technologies Co., Ltd. and SPT Microtechnologies USA, Inc. take the following measures to ensure accessibility of SPT Official Website:

• Include accessibility throughout our internal policies.
• Assign clear accessibility goals and responsibilities.
• Work with external accessibility consultants during development to support conformance with WCAG 2.2 guidelines.

The Web Content Accessibility Guidelines (WCAG) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. SPT Official Website is partially conformant with WCAG 2.2 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.

In addition to aiming for WCAG 2.2 Level AA conformance, we have applied the following accessibility considerations:

• Consistent user interface components are used throughout the website, following a unified design system to support predictability and ease of use.
• Buttons and interactive elements are designed with sufficient size and spacing to prevent accidental operation.
• The website supports multiple languages, including Japanese, English, and Simplified Chinese.
• Language switch options are clearly presented and accessible at the top of each page.
