1The service
Piano Class is the app and website provided by [Tên đơn vị vận hành]. It helps piano teachers manage students, write note-reading and theory questions, assign tests and follow progress; students play and see their results. It is a teaching aid, not a training programme or a certification.
2Accounts
- Teachers must be 18 or older, sign in with their own Google or Apple account, and are responsible for the classes they create.
- Students join through a class code. A student account is created by a parent or a teacher. The teacher confirms that a parent has consented before approving a child into a class.
- Keep your class code, PIN and session to yourself. What happens under your account is your responsibility, unless it is caused by a fault of the system.
- Each student belongs to one teacher. Moving to another teacher means a new account in the new class.
3Content
- Questions, tests and pictures written by a teacher belong to that teacher. We store and show them only to run the service.
- Do not upload content you have no right to use, content unsuitable for children, or content that breaks the law. We may remove such content and tell you.
- A student's results are shown only to the teacher of the class and to the student.
4Plans and payment
- Trial: a new teacher account has every feature and 5 student seats for 14 days, with no payment.
- Plans: after the trial, a teacher chooses a plan by the number of student seats and a term of 6 or 12 months. Every plan has the same features; only the seats differ. Prices are published on the pricing page and may change for later purchases; a plan already bought keeps its price.
- Payment: by bank transfer using the QR code and the transfer memo the app provides. The plan takes effect when we confirm the payment, usually within one working day. Plans do not renew on their own and we never charge automatically.
- Expiry: you can still sign in and see all your data; students can still play what was assigned. Assigning new work and approving more students pause until you renew. No data is deleted because a plan expired.
- Changing plan: renewing the same plan adds the term to the current expiry date; switching to another plan starts a new term on the activation date, and the app says so before you pay.
- Refunds: within 7 days of activation, if you have not approved more students than the trial's seats, we refund in full on request. After that, refunds are agreed case by case.
- Invoices: issued on request by email. Prices include value-added tax where applicable.
5Acceptable use
- Do not try to reach the data of another teacher or student.
- Do not generate automated traffic beyond the published limits, and do not try to crack a PIN.
- Do not resell seats or rent out an account.
- Do not use the service for anything other than teaching and learning.
6Availability
We work to keep the service running continuously but do not guarantee it will never be interrupted. Planned maintenance is announced on the website when possible. Data is backed up nightly. The app needs a network connection to receive exercises and send results.
7Ending
- You can delete your account at any time in the app; see how to delete an account. Deleting does not refund the unused part of a plan, except as described in section 4.
- We may suspend or close an account that breaks these terms, after notice and time to remedy where the law requires it.
- If we stop the service, we give at least 60 days' notice and time to take your data.
8Liability
The service is provided as is. To the extent the law allows, our liability for any claim related to the service is limited to the amount you paid for the current plan in the last 12 months. We are not liable for indirect damage, data lost because of your device, or content created by other users.
9Governing law
These terms are governed by the law of Vietnam. In a dispute, both sides talk first; failing that, the competent court in Vietnam decides.
10Changes and contact
We may change these terms; a significant change is announced in the app to teachers at least 14 days before it takes effect. Using the service after that date is agreeing to the new terms. Questions go to hotro@pianoclass.app.
