Delivery, activation & refund policy

myhappyclass.edu.vn grants online software access by plan. Delivery means granting or updating usage rights on the registered account. There is no physical goods, shipping fee, cash-on-delivery, or packaging inspection.

Use a browser on a phone or computer with Internet access and go to https://app.myhappyclass.edu.vn.

• Create an account as guided in the app, provide accurate information, and complete any required verification.
• Choose a plan/term and check features, limits, total price, renewal, and refund/cancellation terms before confirming. If in-app purchase is not yet available, email support for written confirmation.
• Pay and include the correct order or account identifier.
• myhappyclass.edu.vn reconciles and activates the plan within 1 business day after receiving full payment and account-identifying information. If more information is needed, we notify you within the same period.
• We confirm completion to the registration email, stating the plan, term, start date, and end date. Sign in with the registered account to use the service.

A paid term starts when the plan is activated and you can access it, unless another start date is agreed. Monthly plans follow the calendar month; yearly plans last 12 months. The exact end date and time are in the confirmation, Vietnam time. If the end month has no matching day, the last day of that month is used.

When you receive a plan, check the account, plan name, term, and limits. If they are wrong, we check and correct them to what was purchased, without extra fees for our error. Please report early; not reporting immediately does not automatically remove a lawful complaint right.

If activation is delayed, we explain why and the expected time. You may refuse the new time, cancel the unused part, and receive the matching amount back — or a full refund if the service has not been provided.

Renewal is active: you confirm and pay for the next term; myhappyclass.edu.vn does not auto-charge. For continuous consumer services under Vietnam’s consumer-protection law, we remind you of the renewal fee and contract end date at least 7 business days before expiry. Renewal before expiry continues the current term; renewal after expiry starts when access is reactivated, unless otherwise agreed.

If a paid term ends without renewal, the account returns to HAPPY rights. Data over the HAPPY limit is kept for 15 days from expiry so you can request a copy, rearrange data, or renew. We notify you before restricting or deleting data and state the affected scope. Expiry of a paid plan does not mean immediate deletion of the account or of data that fits the HAPPY limit.

You may request an upgrade, downgrade, or billing-period change by email. Cost differences, remaining-term calculation, and the effective date must be confirmed first. We do not auto-charge extra fees.

Time-based refunds are calculated as the amount actually paid × eligible days / total days of the purchased term, rounded to the nearest đồng, and never more than the matching paid amount. We do not recalculate a yearly plan’s used portion at the monthly list price unless a lawful agreement is more favourable to you.

This policy does not remove cancellation, termination, refund, or compensation rights protected by law. Activation alone does not mean you lose the entire payment.

Paid but not yet activated, and you cancel

Full refund of the unused plan.

Overpayment or duplicate payment

Refund the excess/duplicate after reconciliation; convert to credit only with your consent.

Wrong plan or account activated by myhappyclass.edu.vn

Correct it free of charge; if we cannot deliver the agreed service, refund the unused part, or the full amount if the plan cannot be used.

We cannot continue a sold plan

Refund the unused period and explain how to receive your data.

An incident on our side blocks core features

Fix it; agree a compensatory extension or a refund for the unusable time. If we cannot continue, you may terminate and receive the unused portion back.

The plan was delivered correctly and you no longer need it

No refund of the used portion. The unused portion follows termination rights and a lawful agreement, including the consumer and distance-contract rules below.

If you are a consumer under the law and the plan is a continuous service, you may give notice to terminate at any time and pay only for what was used, unless another lawful agreement applies. Unused prepaid amounts are refunded using the method in section 5.

If myhappyclass.edu.vn omitted or gave incorrect mandatory information in a distance contract, a consumer may terminate within 30 days of conclusion and pay only for what was used. The unused amount must be refunded within 30 days of the termination notice, via the original payment method unless you agree otherwise. Late refunds create legal liability.

Email hello@myhappyclass.edu.vn with the account email, order/transaction code, amount, payment date, reason, and refund-account details. You may hide unrelated information on receipts.

We acknowledge receipt within 1 business day. After confirming eligibility and receiving complete refund details, we refund within 7 business days, unless a shorter legal period applies. If there is an obstacle, we explain why and when it will be handled — we do not extend indefinitely on our own.

Money is returned to the original source or another lawful account confirmed by the parties. myhappyclass.edu.vn bears the transfer fee for refunds caused by our error or over/duplicate collection, and does not charge a refund-processing fee.
