Terms of Use
Last updated: 17 September 2026
These terms govern your use of the osaat.vision website and the OSaaT vision-screening application (together, the "Services"), operated by One School at a Time ("OSaaT"). By using the Services you agree to these terms. If you do not agree, do not use the Services.
Who may use the App
The App is licensed for use by trained ophthalmic technicians, optometrists, ophthalmologists and authorised programme staff acting within their scope of practice and under an agreement with OSaaT or an implementing partner. You must be at least 18 years old and authorised by your organisation. Accounts are personal and must not be shared.
Your responsibilities
- Obtain the school, parental or guardian consent required in your jurisdiction before screening a child
- Enter accurate records and keep device access protected by a screen lock and your own credentials
- Access only the records needed for the care of the child in front of you
- Comply with the health-data, child-protection and privacy laws that apply to you
- Report a lost device, suspected breach or unauthorised access to us without delay
Prohibited use
You may not copy, export, publish or sell screening data outside the programme; attempt to reverse engineer, decompile or interfere with the Services; bypass authentication or access controls; upload malicious code; or use the Services for any unlawful purpose.
Not a substitute for medical care
The App supports screening and record keeping. It does not diagnose eye disease and does not replace a full eye examination or clinical judgement. Screening results must be interpreted by a qualified professional, and any child needing further care must be referred. Content on this website is provided for information only and is not medical advice.
Availability and changes
We aim to keep the Services available and support offline screening with later synchronisation, but we do not guarantee uninterrupted service. We may update, suspend or discontinue features, and may require you to install a newer version of the App.
Intellectual property
The Services, including all branding, written content, photography and software, are owned by OSaaT and its partners. You receive a limited, revocable, non-transferable licence to use the App for programme purposes only. Please contact us before any reuse of our content.
Data protection
Our handling of personal and health information is described in our Privacy Policy, which forms part of these terms.
Suspension and termination
We may suspend or terminate an account that breaches these terms, poses a risk to children's data, or is no longer authorised by its organisation. You may close your account at any time by contacting us.
Disclaimers and liability
The Services are provided on an "as-is" and "as-available" basis without warranties of any kind, to the fullest extent permitted by law. OSaaT is not liable for indirect, incidental or consequential loss, loss of data, or loss of profit arising from use of the Services. Nothing in these terms limits liability that cannot be limited by law.
Governing law
These terms are governed by the laws of the Republic of South Africa, without prejudice to mandatory local protections available to you in your country of residence.
