Legal
Terms of Service
The agreement between you and Wisdomwave Hub for using OET Coach.
Agreement
By using OET Coach, you agree to these Terms of Service with Wisdomwave Hub. If you do not agree, do not use the service.
The service
OET Coach provides personalised preparation for the Occupational English Test (OET®) including diagnostics, adaptive study plans, original practice tasks, offline PWA access, and AI-assisted feedback through Nika.
The service is educational only. Unless we publish a written partnership announcement, we are not affiliated with, endorsed by, or connected to OET or Cambridge Boxhill Language Assessment (CBLA).
Paid subscriptions provide access to OET Coach features only — not to official OET test content, exam registration, or results.
OET® and third-party materials
OET® is a registered trademark of Cambridge Boxhill Language Assessment. We use the name descriptively to explain that our service prepares candidates for that test.
Official OET materials (including sample tests, audio, PDFs, and answer keys) are owned by CBLA. We do not host, sell, or redistribute official test papers or audio on our servers.
Where we reference official OET guidance, we link users to oet.com. You must download official materials yourself and comply with OET's Intellectual Property Policy and Terms & Conditions.
If you import official files for local practice on your device, you confirm you have obtained them lawfully for personal study and that you will not upload them to our servers.
Accounts
You must provide accurate account information and keep credentials secure.
You are responsible for activity under your account.
We may suspend accounts that violate these terms or abuse the service.
Acceptable use
Use the platform only for lawful exam preparation.
Do not upload copyrighted OET materials to our servers. Local import on your device is your responsibility and must comply with OET's terms.
Do not copy, scrape, redistribute, or commercially exploit official OET content through our platform.
Do not attempt to reverse-engineer, scrape, or overload our systems.
Do not include real patient identifiable information in practice content.
Subscriptions & Premium access
Free access. OET Coach provides free access to the healthcare vocabulary feature (/vocabulary). All other features — including Nika AI tutor, diagnostic assessment, adaptive study plans, practice across Listening, Reading, Writing and Speaking, mock exams, progress tracking, and course materials — require an active OET Coach Premium subscription or an active free trial.
Plans. We offer subscription plans billed every two weeks, monthly, or every three months. Prices are listed in US dollars (USD), euros (EUR), and British pounds (GBP). We automatically select GBP for customers in the United Kingdom, EUR for customers in the European Union and European Economic Area, and USD for all other countries, unless you choose a different listed currency before checkout. Prices are fixed per currency — we do not convert at the payment gateway. Current prices are shown at /pricing and in your Profile before checkout. The quarterly plan is discounted approximately 20% compared to three monthly payments.
Free trial. New subscribers may receive a three (3) day free trial with full Premium access on the two-week plan only. You must provide a valid payment method before the trial starts. Unless you cancel before the trial ends, your chosen plan will be charged automatically when the trial ends. Monthly and three-month plans are charged immediately and do not include a free trial. Each user is entitled to one (1) free trial unless we grant otherwise in writing.
Auto-renewal. Subscriptions renew automatically at the end of each billing period until you cancel. You will be charged the then-current price for your plan (minus any applicable discount).
Cancellation. You may cancel at any time from Profile → Manage subscription (Stripe Customer Portal). Cancellation stops future charges. You retain Premium access until the end of the current billing period (or trial), after which your account reverts to free vocabulary-only access.
Changing plans. You may change plans from Profile. If you are on a free trial, the new plan replaces the trial plan and bills when the trial ends. If you are on a paid period, the new plan generally starts after your current billing period ends so you keep access you have already paid for. Starting a second overlapping paid subscription while one is active is not supported. Complimentary access granted by us is not a Stripe subscription and is managed separately.
Price changes. We may change subscription prices for future billing periods. We will give you reasonable notice (email or in-app) before a price increase affects your subscription. Continued use after notice constitutes acceptance.
Failed payments. If a payment fails, we may suspend Premium access until payment is resolved. Vocabulary access remains available.
Refunds & withdrawal
No refunds. Subscription fees are non-refundable. We do not provide refunds or credits for partial billing periods, unused time, downgrades, or failure to use the service.
Statutory rights. Nothing in these Terms affects your statutory rights as a consumer that cannot be excluded by law.
EU/UK right of withdrawal. If you are a consumer in the UK or European Economic Area, you normally have a 14-day right to cancel distance contracts. For digital content supplied immediately, you acknowledge and agree that: (1) you request immediate access to OET Coach Premium (or trial access) on starting your subscription; and (2) you understand that you lose your right of withdrawal once digital delivery begins (i.e. when Premium or trial access is activated). You confirm this before completing checkout via an explicit consent control.
Chargebacks. Unauthorised chargebacks may result in account suspension. Contact support@nika-oet.fun before disputing a charge.
AI-generated content
Nika and AI feedback are automated and may contain errors.
Always verify guidance against official OET materials and qualified tutors.
Mock scores and grade estimates are approximate — only official OET results count.
We do not guarantee exam results or registration outcomes.
Intellectual property
Platform design, Nika character, and original content are owned by Wisdomwave Hub.
You retain ownership of your writing and recordings. You grant us a licence to process them solely to provide feedback and progress tracking.
OET trademarks, logos, and official test content remain the property of CBLA. We do not claim ownership of OET materials. Any future use of OET branding on our site will follow written approval from CBLA only.
Availability
We aim for high availability but do not guarantee uninterrupted access.
Offline features depend on your device storage and prior sync.
We may update or discontinue features with reasonable notice.
Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect, incidental, or consequential damages arising from use of the service.
Our total liability is limited to the amount you paid us for subscriptions in the twelve (12) months before the claim.
Nothing in these terms excludes liability that cannot be excluded under applicable law.
Termination
You may delete your account at any time from Profile settings.
You may cancel a subscription at any time; cancellation stops future renewals. Access typically continues until the end of the current paid period unless stated otherwise at checkout.
We may terminate access for breach of these terms.
Upon termination, server-held data is deleted per our Privacy Policy.
Governing law
These terms are governed by the laws of England and Wales.
