Terms of Service

Last updated 8 November 2026

These terms apply to your use of Bandwise, an online workspace for teachers preparing students for English exams such as IELTS, Cambridge B2 First, C1 Advanced and C2 Proficiency, and the Michigan ECCE and ECPE, operated by Panagiotis Chatzigiannakis (“we”, “us”). By creating an account or using Bandwise, you agree to them.

1. The service

Bandwise helps teachers record students’ exam practice, get AI-assisted score estimates and written feedback, and share reports. Estimates are practice estimates, not official exam results, and they can be wrong. You are responsible for reviewing every score and piece of feedback before you rely on it or share it.

Comparisons with a student’s class writing are prompts for a conversation, not evidence. They do not show whether a student had help or used AI, and you must not use one on its own to accuse, mark down or penalise a student. Talk with the student first.

IELTS is a registered trademark of the British Council, IDP IELTS and Cambridge University Press & Assessment. A2 Key, B1 Preliminary, B2 First, C1 Advanced and C2 Proficiency are trademarks of Cambridge University Press & Assessment. ECCE and ECPE are trademarks of Michigan Language Assessment. Bandwise is independent and is not affiliated with or endorsed by any of them.

2. Your account

Bandwise is for teachers and schools, not for students to use directly. New accounts may need our approval before they can be used. Keep your sign-in secure and tell us straight away if you think someone else has used your account. You are responsible for activity in your account.

3. Your content and your students’ data

You keep all rights to the content you add. You allow us to store and process it only as needed to provide Bandwise to you, including sending it to Bandwise AI when you ask for an assessment. You also allow us to use the scores you give when you review Bandwise AI’s drafts, combined with other teachers’ and without identifying you or your students, to improve Bandwise AI’s marking for everyone, as described in section 5 of our Privacy Policy. You can turn this off in Settings → Your marking.

You confirm that you have the right to add your students’ information and work, including any consent needed from students or, for children, their parents or guardians. You must only upload material you have the right to use, and must not upload copyrighted test content (such as full Cambridge test papers or audio) unless you are allowed to. How we handle personal data is explained in our Privacy Policy.

4. Schools

A school account is set up with the school, which names its school admins. The school is responsible for its admins and teachers, and for the students’ information they add. Where a school has signed our Data Processing Agreement, it applies to the personal data it covers.

Some school features are available only when we have agreed them with the school, and may carry fees set out in that agreement: a test bank of the school’s own prompts, the school’s courses or custom exams, and teaching Bandwise AI to mark like the school’s teachers. If such a feature is switched off (for example, when the agreement ends), it stops affecting how the school’s work is set and marked. We keep what the school added, so the feature can be switched back on as it was; meanwhile the school can download it with its data and ask us to delete it, and it is deleted with the school’s account.

When a school uses these features:

• Its content. The school confirms it has the right to upload its prompts, rubric documents, marked essays and recordings of marked speaking tests, and to use them this way. Marked essays and recordings must not identify students, or the school must have its own lawful basis for using them. We use them only to provide these features to that school: never for another school, and never to improve Bandwise AI for everyone.
• Its decisions. The school decides its courses or custom exams, criteria and rubrics, and which tips, example essays and score adjustments Bandwise AI uses for its teachers. Bandwise shows how each one changes Bandwise AI’s scores on the school’s own essays before the school starts using it, but only the school starts using it, and it remains responsible for how its students are marked. Scores remain practice estimates, and teachers must still review every one.
• Help from Bandwise. If the school’s admin lets Bandwise help set up its exams and marking, for a period they choose, Bandwise staff may open those parts of the school’s account and draft and try things out there. Everything they change is shown to the school, and only the school starts using anything.
• Its teachers. School admins can see how each teacher’s reviewed scores compare with Bandwise AI’s and with colleagues’, by name. The school should use this to help its teachers mark consistently, and tell its teachers about it; Bandwise tells each teacher too.

5. AI providers

Bandwise AI runs on third-party AI services. We are not responsible for third-party services or their availability.

Bandwise AI comes with a monthly allowance of credits (currently 1 credit for a writing assessment, 3 for a speaking test, and 1 to compare an essay with a student’s class writing). When the allowance runs out, Bandwise AI is paused until it renews at the start of the next month. We may change the allowance, and will show your current allowance in the app. Section 8 explains the credits that come with paid plans.

6. Acceptable use

Don’t use Bandwise to break the law or others’ rights, to upload harmful code, to try to access other teachers’ data, to overload or probe the service, or to resell it without our agreement. We may suspend accounts that do.

7. Early access and pricing

Bandwise is in early access. Features may change, and there may be interruptions. There is currently no charge from us for teachers’ accounts. If we introduce paid plans, we will tell you in advance, and you won’t be charged unless you choose a paid plan. Any fees for a school account or its features are those agreed with the school in writing.

During early access we may ask for your feedback, including what you would pay for Bandwise. Answering is optional, and your answers help us set fair prices; they do not commit you to anything.

8. Paid plans and payments

If you choose a paid plan, this section applies to it. Paid plans are not on sale yet. When they are, new accounts will start with a free trial of 50 credits and up to 10 students, with no card needed.

Plans and prices

When paid plans open, Bandwise will offer Tutor, Pro, Team and School plans, and Organisations plans by quote. Our pricing page and the Billing page in the studio show what each plan includes and what it costs. Prices for teacher plans include VAT. Prices for Team and School plans, and for the credit packs a school buys, are before VAT. Payments are handled by Stripe. The seller named on your invoice or receipt is the seller of your plan or credit pack.

Subscriptions and cancelling

A plan is a subscription, monthly or yearly as you choose. It renews automatically at the end of each period until you cancel, and we charge the payment method you gave. You can cancel at any time on the Billing page, or in the payment portal it links to. Cancelling takes effect at the end of the period you have paid for: you keep your plan until then, and we do not charge you again. We do not refund the unused part of a period, unless the law requires us to.

If we change our prices, you keep the price you subscribed at for as long as your subscription continues. New prices apply to new subscriptions only.

Credits

• Included credits. Each plan includes credits for Bandwise AI every month, also on yearly plans. Unused included credits do not roll over to the next month.
• Extra credit packs. You can buy extra credits. They never expire, and they are used once your included credits for the month have run out. You can use them only while you have an active plan.
• When a plan ends. The extra credits you bought are kept, but you cannot use them until you have an active plan again.

Founding Teacher discount

Teachers who qualify for the Founding Teacher offer get 40% off for 12 months on a monthly plan. It is for monthly plans only, not yearly ones, and once for each account. You must subscribe within 3 months of Bandwise opening to everyone; the Billing page shows the last day. If you qualify after you have subscribed monthly, the discount starts with your next payment. It does not start again if you cancel and later return.

If a payment fails

If a renewal payment fails, you will see a notice on the Billing page and Stripe will email you, and you have 14 days to put it right. During that time you can keep working, but your plan does not give you new monthly credits. If the payment is still missing after 14 days, your account becomes read-only: you can see, download and delete your work, but cannot create or mark new work until you have paid.

Refunds and disputes

• If we refund a plan payment in full, the plan ends. A partial refund does not end it.
• If you dispute a plan payment with your bank and the dispute is decided against us, the plan ends.
• If a credit pack is fully refunded, or a payment dispute about it is decided against us, the credits from that pack are removed from your balance, never more than you have left.

If something is wrong with a payment, please write to us before you ask your bank to reverse it.

Your right to change your mind (consumers)

If you buy as a consumer in the European Union, meaning for purposes outside your trade, business or profession, you normally have 14 days to withdraw from a purchase. Bandwise starts as soon as you pay. By buying, you ask us to start straight away and you agree that your right to withdraw ends once the service has been fully provided, or, for credits, as you use them. If you withdraw within the 14 days before that, we will refund what you paid, less a fair amount for what you have already used. To withdraw, email hello@bandwiseapp.com.

Schools

A school admin who buys a plan does so for the school, and confirms they may. A school can add extra teachers at the price shown on the pricing page. The school’s teachers share the school’s credits. As section 4 says, the school is the controller of its students’ information.

Students and archiving

Each plan has a number of students. You can archive a student to free a place. An archived student stays listed, and you can view, download and restore them. Three months after a student is archived, the student and their work are planned for deletion, and we email you before that. Our Privacy Policy explains the details.

Deleting your account

If you delete your account (or a school admin deletes the school), we first cancel any active subscription, so you are not charged again. We keep invoices as the tax law requires.

9. Availability and liability

We work to keep Bandwise available and your data safe, but we provide it “as is”, without guarantees that it will be uninterrupted or error-free. Keep your own copies of anything important. To the extent the law allows, we are not liable for indirect or consequential losses, or for decisions made on the basis of practice estimates. Nothing in these terms limits liability that cannot be limited by law, or your rights as a consumer.

10. Ending your use

You can stop using Bandwise at any time and ask us to delete your account at hello@bandwiseapp.com. We may suspend or close accounts that break these terms. Where we can, we will warn you first and give you time to export your data. If you have a paid plan, section 8 explains what happens to it.

11. Changes and law

We may update these terms. For significant changes, we will tell signed-up teachers by email before they take effect. These terms are governed by the laws of Greece, without affecting any mandatory consumer protections of the country where you live.
