OnceraPlus Terms of Service
Last updated: 1 October 2026
These Terms govern your use of the OnceraPlus website, account and assessment service (‘the Service’). By creating an account or using the Service, you agree to these Terms.
Our Privacy Policy and Cookies Policy also apply to your use of OnceraPlus.
1. Who we are
OnceraPlus is operated by Oncera Ltd, a company registered in England and Wales under company number 16763560, with its registered office at 64 Central Drive, Hornchurch, England, RM12 6BA. You can contact us at info@onceraplus.com or through our contact form.
2. What OnceraPlus does
OnceraPlus is an AI-based decision-support tool that uses clinical information you provide to estimate the risk of immunotherapy-related side effects in people with lung cancer.
Its results are probabilistic and depend on the information provided. A result does not establish that you do or do not have a particular disease or condition.
OnceraPlus is not a diagnosis and does not replace professional medical advice, examination or clinical judgment. Results are intended to support a conversation with a qualified doctor or care team.
Do not delay seeking medical advice, disregard professional medical advice or change treatment solely because of an OnceraPlus result. OnceraPlus is not an emergency medical service. If you think you may need urgent or emergency medical attention, contact the appropriate medical service.
3. Who can use OnceraPlus
You must be at least 18 years old to create an account.
You may enter personal or health information about another person only where you are authorised to provide that information and use OnceraPlus on their behalf. We may ask you to confirm this before you submit their information.
You are responsible for ensuring that information you provide is, to the best of your knowledge, accurate and complete.
4. Your account and acceptable use
You are responsible for keeping your login details confidential and must tell us promptly if you believe somebody else has accessed your account.
You must not misuse OnceraPlus, including by:
- accessing or attempting to access another person's account or data;
- circumventing payment, security or technical restrictions;
- introducing malicious software or interfering with the Service;
- scraping or systematically extracting content or data from the Service;
- reverse engineering our software or technology, except where applicable law prevents us from restricting this; or
- using OnceraPlus, its content or outputs to develop, train, fine-tune or validate another AI system without our written permission.
5. Assessments, payments and subscriptions
Assessments are currently available as part of a subscription. We may also offer assessments that can be purchased individually or as additional top-ups. The applicable price and what is included will be shown before you purchase.
Payments are processed by Stripe. We do not store your complete payment-card details.
If you purchase a subscription, payments will be taken at the intervals shown when you subscribe. Subscriptions renew automatically until cancelled and can be cancelled at any time, effective at the end of the current billing period, from your account dashboard.
6. Refunds
You generally have a 14-day right to cancel a service purchased online, starting when the contract is entered into.
OnceraPlus assessments are provided immediately after you submit the required information. By asking us to provide your assessment straight away, you expressly request that we begin providing the Service during the 14-day cancellation period and acknowledge that you will lose your right to cancel once the Service has been fully provided during that period.
Once your assessment report has been generated and made available to you, the Service has been fully provided and you will no longer be entitled to cancel that assessment because you have changed your mind.
This does not affect any other rights you may have if there is a problem with the Service.
If you believe you have been charged incorrectly, have not received an assessment you purchased because of a technical failure, or there is something wrong with the Service we provided, please contact us at info@onceraplus.com.
7. Intellectual property
We or our licensors own the intellectual property rights in OnceraPlus, including its software, models, algorithms, design and content.
We give you a personal, non-exclusive and non-transferable right to use OnceraPlus for its intended purpose while you are entitled to access the Service.
You may use and share an assessment report generated for you for your personal healthcare purposes, including with healthcare professionals involved in your care.
You must not commercially exploit, reproduce or distribute our Service or proprietary content without our permission.
8. Your information and privacy
We process personal information, including health information, as described in our Privacy Policy.
The Privacy Policy explains what information we collect, why we use it, the lawful bases on which we process it, who we share it with and your data protection rights.
9. Availability and changes to OnceraPlus
We do not guarantee that OnceraPlus will always be available or uninterrupted. We may suspend access where reasonably necessary for maintenance, security, technical reasons or compliance with legal or regulatory requirements. We may update OnceraPlus as the technology develops.
10. Suspension and closing your account
You can stop using OnceraPlus and close your account at any time by contacting us at info@onceraplus.com or by using ‘Delete account’ in your account dashboard. You can cancel a subscription separately from your account dashboard. Closing your account does not automatically cancel a subscription unless we expressly tell you otherwise.
We may suspend or close your account if you materially or repeatedly breach these Terms, fail to make a payment that is due, create a security risk, or where we are required to do so by law.
Where appropriate, we will give you reasonable notice and an opportunity to resolve the problem.
11. Limits of our responsibility
Nothing in these Terms excludes or limits liability where it would be unlawful to do so or excludes any statutory rights you have as a consumer.
OnceraPlus provides the decision-support functionality described in clause 2. Its outputs are probabilistic and their usefulness may be affected by the accuracy and completeness of the information provided.
We are not responsible for losses arising from using an OnceraPlus assessment for a purpose for which the Service is not intended, or from relying on it as a diagnosis or substitute for professional medical advice or clinical judgment. We are also not responsible for losses resulting from inaccurate or incomplete information you provide, to the extent that this affects the assessment.
We are not responsible for losses that were not reasonably foreseeable when we entered into the contract, losses caused by events outside our reasonable control where we have taken reasonable steps to minimise their effects, or losses you could reasonably have avoided by following information or instructions we provided.
12. Medical disclaimer
OnceraPlus is an AI-based decision-support tool. No result it produces is, or should be treated as, a medical diagnosis. A result does not tell you to start, stop, or change any treatment. It is intended to support — not replace — a conversation with a qualified doctor or care team, who can weigh it alongside the full clinical picture. Every result is expressed as a probability, generated by a statistical model based on the information you provide. Even a result at either extreme of the scale reflects a likelihood, not a guaranteed outcome, and individual results can differ from what a model predicts.
13. Changes to these Terms
We may make minor changes to these Terms to correct errors, improve clarity, address security issues or reflect changes in law, regulation or the Service.
If we make a change that materially affects an existing paid Service or your rights under it, we will give you notice and any right to end the contract required by law.
The date at the top shows when these Terms were last updated.
14. General
We may transfer our rights and obligations under these Terms to another organisation, provided this does not reduce your rights. We will tell you where required.
If a court or other authority finds part of these Terms unlawful or unenforceable, the rest will continue to apply.
If we delay enforcing these Terms, that does not mean we have given up our right to enforce them later.
These Terms are between you and us. No other person has a right to enforce them.
15. Complaints, governing law and courts
If you have a problem with OnceraPlus, please contact us at info@onceraplus.com and we will try to resolve it.
These Terms are governed by English law. Nothing in these Terms affects any mandatory rights you may have under the laws that apply to you as a consumer.
