Terms of Service
Last updated: 15 June 2026
These Terms govern your use of Opti at optieducation.app (the “Service”). By creating an account or using the Service, you agree to these Terms. If you don’t agree, please don’t use the Service.
1. Who we are
Opti is an independent ESAT study tool operated by an individual based in Belgium. Contact: optiapp.business@gmail.com.
2. Eligibility & age
You must be at least 13 years old to use Opti. If you are under 16, you confirm that a parent or guardian has given you permission to use it. By using the Service you confirm you can form a binding agreement under the law that applies to you (if you are a minor, that a parent or guardian agrees to these Terms on your behalf).
3. The Service
Opti helps you practise for the ESAT using a curated question bank, the official specification, timed practice sessions, and study tools. It is a study aid only. We do not guarantee any particular exam result, score, or admission outcome, and our questions and worked solutions are provided to help you learn — they may contain errors and are not official exam materials.
4. Not affiliated with the exam
Opti is an independent product. It is not affiliated with, endorsed by, or connected to the University of Cambridge, Imperial College London, Pearson VUE, UCLES, or any official ESAT body. “ESAT” and any related names are the trademarks of their respective owners and are used only to describe what Opti helps you practise for.
5. Your account
You agree to give accurate information, keep your password secure, and not share your account. You are responsible for activity under your account. Tell us promptly at optiapp.business@gmail.com if you suspect unauthorised use.
6. Acceptable use
You agree not to:
- copy, scrape, redistribute, or resell the question bank, solutions, or other Service content;
- reverse-engineer, disrupt, or attempt to gain unauthorised access to the Service;
- exceed or circumvent rate limits, or use bots or automation against the Service; or
- use the Service for anything unlawful.
We may suspend or terminate accounts that breach these Terms.
7. Your content
You keep ownership of the reflections and notes you write (“Your Content”). You grant Opti a limited licence to store and process Your Content solely to provide the Service to you (including the processing described in our Privacy Policy). You confirm the content you provide is your own.
8. Our content
The Service and its content — including the question bank, specification mappings, worked solutions, design, and software — are owned by or licensed to Opti and are protected by intellectual-property law. We grant you a personal, non-transferable, non-exclusive right to use the Service for your own study. No other rights are granted.
9. Price
Opti is currently free to use. If we introduce paid plans, the price and the specific terms (including any rights you have to cancel or to a refund) will be shown to you clearly before you pay, and you’ll be asked to agree to them at that point. Nothing here removes the consumer rights you have under the law that applies to you.
10. Disclaimers
The Service is provided “as is” and “as available”. We don’t warrant that it will be uninterrupted, error-free, or that its content is accurate or complete. To the fullest extent permitted by law, we disclaim implied warranties.
11. Limitation of liability
To the fullest extent permitted by law, Opti will not be liable for indirect or consequential losses, or for loss arising from your reliance on the Service’s content for exam outcomes. Nothing in these Terms limits liability that cannot be limited by law, including your mandatory rights as a consumer.
12. Suspension & termination
You can stop using Opti and delete your account at any time. We may suspend or end your access if you breach these Terms or to protect the Service or its users.
13. Changes
We may update these Terms. We’ll change the “Last updated” date and, for significant changes, take reasonable steps to let you know. Continuing to use the Service after changes means you accept them.
14. Governing law & disputes
These Terms are governed by Belgian law. If you are a consumer, you also keep the protection of the mandatory rules of the country you live in, and you can bring proceedings there. EU consumers can also use the European Commission’s Online Dispute Resolution platform.
