Terms of Use & Medical Disclaimer

1. About these terms

These Terms of Use ("Terms") are an agreement between you and R.Tej Health Analytics Private Limited ("R-Tej", "we", "us"), the publisher of the Emma mobile application ("Emma" or the "app"). They govern your access to and use of the app.

By downloading, installing, or using Emma, you confirm that you accept these Terms and agree to comply with them. If you do not agree, please do not use the app. Your use of Emma is also governed by our Privacy Policy, which forms part of these Terms.

Your use of the app is additionally subject to the terms of the Apple App Store, from which you downloaded it. Where those store terms conflict with these Terms in relation to the store's own role, the store terms prevail for that purpose.

2. Medical disclaimer — please read carefully

In particular, you understand and agree that:

• Emma's information is general in nature and is not tailored to your individual medical circumstances.
• Emma does not diagnose conditions, prescribe or adjust medication, or recommend specific treatment for you personally.
• You should always follow the instructions of your own eye-care team, including how and when to use your eye drops. Where Emma's general information appears to differ from your clinician's instructions, your clinician's instructions always take priority.
• You should never disregard, delay, or stop seeking professional medical advice because of something you have read or heard in Emma.
• No doctor–patient or other professional–client relationship is created between you and R-Tej by your use of the app.

While Emma draws its information from reputable government and public-domain sources (such as the NHS, MedlinePlus, the US National Eye Institute and the US FDA) and is designed to answer carefully, we cannot guarantee that every answer is complete, current, or applicable to your situation. Always verify important health decisions with a qualified professional.

Emma's answers are generated by artificial intelligence. Emma's responses are produced by AI models running on your device. AI can produce information that is incomplete, out of date, or incorrect. Treat Emma's answers as general information to discuss with your eye-care team — never as instructions to act on directly.

3. In an emergency

4. Not a medical device

Emma is a general wellness and information tool. It is not intended to be, and has not been certified or approved as, a medical device under the UK Medical Devices Regulations, the EU Medical Device Regulation, or any equivalent regime. Emma is not intended to diagnose, cure, mitigate, treat, or prevent any disease or condition.

5. Who can use Emma

Emma is intended for adults aged 18 or over. By using the app, you confirm that you are at least 18 years old (or the age of majority in your jurisdiction) and are capable of entering into a binding agreement. Emma is not directed at, and should not be used by, children.

6. Your device and your data

Emma is designed to run on your own device, and your health information stays on that device — see our Privacy Policy for the full detail. You are responsible for:

• keeping your device and its security features (passcode, Face ID / Touch ID) secure;
• the accuracy of the information you choose to record in your Journey Log; and
• backing up your data if you wish to keep it — for example, by enabling the optional iCloud backup. If you uninstall the app without a backup, your on-device data is permanently deleted and cannot be recovered by us, because we never had it.

Emma does not require you to create an account or provide personal details to us.

7. Price and billing

Emma is a one-time purchase. The headline price is £24.99 in the United Kingdom; the price in your country is shown to you by the Apple App Store before you buy and is set by Apple's regional pricing. There is no subscription and no recurring charge.

• One-time payment: you pay once and the app is yours. You are not billed again, and there is nothing to cancel.
• Family Sharing: your purchase can be shared with members of your family group at no extra cost through Apple's Family Sharing, in accordance with Apple's rules.
• Payments & refunds: all payments are processed by the Apple App Store, which is the seller and merchant of record for your purchase — not R-Tej. We never see your card or bank details. Refunds are handled under Apple's policies; we do not directly process payments or refunds.
• Sponsored access: some users receive Emma free of charge where a clinic, charity, or other institution has sponsored their access. Sponsored access is granted directly and is not a purchase you make through the app store. It may be time-limited or revocable in line with the sponsor's arrangement, and sponsors receive no personal or health data about you.
• Your statutory rights: nothing in these Terms removes any non-waivable consumer rights you have under the law of your country, including, where you are a consumer, any right to cancel a purchase of digital content within the period allowed by the law of your country.

8. Acceptable use

You agree to use Emma only for lawful, personal, non-commercial purposes, and not to:

• copy, modify, reverse-engineer, decompile, or attempt to extract the app's source code or AI models, except to the extent this restriction is prohibited by law;
• resell, redistribute, sublicense, or commercially exploit the app or its content;
• use the app in any way that breaches any applicable law or regulation, or that could damage, disable, or impair the app;
• rely on the app as a substitute for professional medical care (see Section 2).

9. Intellectual property

The app, its design, the "Emma" name and branding, the curated knowledge base, and all related content (excluding third-party content such as the coaching videos and the underlying open-source and licensed components) are owned by R-Tej or its licensors and are protected by intellectual-property laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for your own personal use, in accordance with these Terms. No other rights are granted.

Emma's health information is drawn from public-domain and government sources, which remain the property of their respective owners.

10. Third-party services and content

Emma uses or links to certain third-party services, each governed by its own terms and privacy policy:

• Coaching videos are hosted on YouTube (Google LLC). Playing a video connects your device to Google. See Google's Privacy Policy.
• Optional iCloud backup is provided by Apple Inc. under Apple's iCloud terms.
• App distribution and payment are provided by the Apple App Store under its terms.

We are not responsible for the content, policies, or practices of these third parties.

11. Apple App Store — additional terms

Emma is licensed, not sold, to you, and is made available to you through the Apple App Store. The following additional terms, required by Apple, apply to your use of Emma. You acknowledge and agree that:

These Terms are concluded between you and R-Tej only, and not with Apple Inc. ("Apple"). Apple is not responsible for Emma or its content. Apple has no obligation to provide any maintenance or support for Emma. In the event of any failure of Emma to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price to you; to the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to Emma. Apple is not responsible for addressing any claims by you or any third party relating to Emma or your use of it — including product-liability claims, any claim that Emma fails to conform to any legal or regulatory requirement, and claims arising under consumer-protection or privacy law — nor for investigating, defending, settling, or discharging any claim that Emma infringes a third party's intellectual-property rights. You represent that you are not located in a country that is subject to a US Government embargo or that has been designated by the US Government as a "terrorist-supporting" country, and that you are not listed on any US Government list of prohibited or restricted parties. You will comply with any applicable third-party terms of agreement when using Emma. Apple and its subsidiaries are third-party beneficiaries of these Terms, and Apple has the right to enforce these Terms against you as a third-party beneficiary.

12. Disclaimers

Emma is provided on an "as is" and "as available" basis. To the fullest extent permitted by law, R-Tej makes no warranties or representations, express or implied, about the app — including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that its information is complete, accurate, or suitable for your particular circumstances.

This Section does not exclude or limit any liability that cannot be excluded or limited under applicable law, including your non-waivable rights as a consumer.

13. Limitation of liability

To the fullest extent permitted by law, R-Tej and its directors, employees, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, arising out of or relating to your use of (or inability to use) Emma.

Nothing in these Terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be limited or excluded under applicable law. Because Emma does not provide medical advice and is not a substitute for professional care (Section 2), you remain responsible for decisions about your health, made together with your healthcare professionals.

14. Changes to the app and these Terms

We may update the app and these Terms from time to time — for example, to add features, reflect changes in the law, or improve clarity. When we make a material change to these Terms, we will update the "Last updated" date above and, where appropriate, notify you within the app. Your continued use of Emma after a change takes effect means you accept the updated Terms.

We may also modify, suspend, or discontinue the app (or any part of it) at any time, although we will give reasonable notice where we can.

15. Governing law and disputes

These Terms, and any dispute arising out of or in connection with them or your use of Emma, are governed by the laws of England and Wales. If you are a consumer, wherever you are resident, you benefit from any mandatory consumer-protection provisions of the law of the country in which you live, and you may bring proceedings in your local courts. Otherwise, the courts of England and Wales will have non-exclusive jurisdiction.
