EyeSay, EyeSay AAC, the EyeSay aperture mark, the EyeSay wordmark and the tagline “Their world. Their words. Their voice.” are trade marks of Prodia Systems Limited used in the course of trade. Prodia and Prodia Systems are trade marks of Prodia Systems Limited.

• Reproduce, adapt, redistribute or republish substantial parts of this website or the EyeSay software commercially, or as part of a competing or derivative product.
• Use the EyeSay or Prodia names, marks or brand assets in a way that suggests endorsement, partnership, certification or official status, or that could confuse a family or service about who is responsible for a product.
• Alter, recolour, redraw, animate or combine our marks with other elements, remove copyright or trade mark notices, or present modified material as ours.

This website uses third-party and open-source components under their own licences, including the Atkinson Hyperlegible typeface family, which was created by the Braille Institute of America and is used under its open font licence. Those components remain the property of their authors, and their licences prevail over this page in respect of that material.

The service providers behind the website and the console are listed in our service provider register.

If you believe material published here infringes your copyright, trade mark or other right, contact us with enough detail to identify the material, the right you rely on, and your contact details. We will acknowledge within 5 working days, review promptly, and remove or correct anything we cannot properly justify.

Please also tell us if you find EyeSay branding used elsewhere in a misleading way. Because this product is used by families supporting nonspeaking communicators, brand confusion is a safety concern as well as a legal one.
