Cancellation and Refund Policy

• Monthly plans (Premium and Mantap Pro), and existing Yearly plans, renew automatically. You can cancel them yourself at any time (see section 3).
• After you cancel, no further charges are made and Premium stays active until the end of the period you have already paid for.
• The 12-month pass (Premium or Mantap Pro) is a one-off payment. It does not renew automatically, so there is nothing to cancel.
• No refunds for any plan, including any part of a period you have not used, except in the three situations in section 7.
• Those three situations are a duplicate charge, a charge after cancellation, and a charge caused by a technical or billing error on our side. In these situations, we fully refund the affected charge.
• Your rights under Malaysian consumer law are not affected. See section 12.

Premium can only be bought by a parent, guardian or teacher signed in to their account, through Kawasan Ibu Bapa (Parent Area) → Akaun (Account) → Naik taraf ke Premium (Upgrade to Premium). All prices are in Malaysian Ringgit (MYR).

• Monthly (Bulanan): RM 4.90 per month. Renews automatically every month until you cancel. If you cancel, Premium ends at the end of your current billing period (the date shown on the Premium page).
• Yearly (Tahunan): RM 99 per year. Renews automatically every year until you cancel. If you cancel, Premium ends at the end of your current billing period (the date shown on the Premium page). No longer sold to new customers from 20 October 2026; existing subscriptions continue at their original price.
• 12-month pass (Pas 12 bulan): RM 49, one-off payment. 12 months of Premium with no automatic renewal. Suitable if you want to pay by FPX online banking, where available. It simply ends after 12 months.
• Mantap Pro Monthly: RM 9.90 a month. Renews automatically every month until you cancel it. If cancelled, the plan ends at the end of the current billing period.
• Mantap Pro Yearly: RM 199 a year. Renews automatically every year until you cancel it. If cancelled, the plan ends at the end of the current billing period. No longer sold to new customers from 20 October 2026; existing subscriptions continue at their original price.
• Mantap Pro 12-month pass: RM 99, one-off payment. 12 months of Mantap Pro with no automatic renewal. You can pay by card or FPX, where available. It simply ends after 12 months.

Premium benefits are listed in section 4 of our Terms of Service.

Payments are processed by Stripe through Stripe Checkout. Mantap Math never sees or stores your card number.

Premium starts as soon as Stripe confirms your payment, usually within seconds. If your status has not changed, reload the page or email us at sokongan@mantapmath.app.

You can cancel a Monthly or Yearly plan at any time, without needing to contact us:

• Step 1: Sign in and open Kawasan Ibu Bapa (Parent Area). Enter your PIN if you have set one.
• Step 2: Select Akaun (Account), then Urus Premium (Manage Premium).
• Step 3: Select Urus langganan · resit · tukar kad (Manage subscription · receipts · change card). The Stripe customer portal will open.
• Step 4: Select Cancel subscription and confirm.

The Stripe portal may show button labels in another language, depending on your browser settings.

To avoid the next charge, cancel before the renewal date shown on the Premium page. Stopping using Mantap Math or archiving a child profile does not cancel your subscription.

You can archive (hide) a child profile yourself with the Buang (Remove) button in Kawasan Ibu Bapa (Parent Area) → Akaun (Account). Its learning data stays stored until you ask us to delete it by emailing sokongan@mantapmath.app.

If you cannot cancel through the portal (for example, you cannot sign in), email sokongan@mantapmath.app from your account email and ask us to cancel. We will cancel it for you. Your request counts as a successful cancellation from the date we receive your email.

If you ask us to delete your account, we will first cancel any Monthly or Yearly subscription that is still active, so that no further charges are made. Your deletion request counts as a successful cancellation from the date we receive it.

Any remaining Premium time you have paid for, including a 12-month pass, is not refunded. Payment records kept by Stripe are retained as the law requires.

After you cancel, no further charges are made and Premium stays active until the end of the period you have already paid for. The Premium page then shows “Langganan dibatalkan. Premium kekal hingga” (Subscription cancelled. Premium remains until) followed by the end date. After that date, your account returns to the free plan; your children's profiles and progress records stay in the account.

Changed your mind? Before the end date, select Renew subscription in the same portal. You will not be charged until the original renewal date.

To prevent double charges, while Premium from a Monthly or Yearly plan is still running, including after cancellation until its end date, you cannot buy another plan, including the 12-month pass. If you change your mind after cancelling, select Renew subscription in the Stripe portal. Once Premium has ended, you can subscribe again at any time.

• A single payment for 12 months of Premium. There is no automatic renewal and no further charge afterwards.
• For all plans, you can pay by debit or credit card, or other methods Stripe shows at checkout, such as FPX for the 12-month pass where available.
• If your current Premium comes from a 12-month pass, a new pass you buy is added after your current end date, so you lose no days. A Premium pass holder can upgrade by buying a Mantap Pro pass: Mantap Pro opens straight away and the new 12 months are added after your current end date. An active Mantap Pro pass can only be extended with another Mantap Pro pass. You can subscribe to a Monthly plan once your pass has ended.
• While Premium from a Monthly or Yearly plan is still running, you cannot buy a pass (see section 4).
• To continue Premium, buy a new pass, or subscribe to a Monthly plan after your pass ends.
• The 12-month pass is not refundable, including any unused months, except in the three situations in section 7 or where the law gives you a right to a refund.

We do not give refunds, including for partly used periods and for the 12-month pass, except in the three situations below or where the law, including the Consumer Protection Act 1999, gives you a right to a refund.

No refund is given for:

• the unused part of a period, for example if you cancel halfway through a month or year
• a 12-month pass, even if only part of it has been used
• periods when your child did not play at all
• an automatic renewal charged because the subscription had not been cancelled (in the portal or by email) before the renewal date

Cancelling stops future charges, but does not return payments already made.

This no-refund rule does not limit your legal rights if we close Mantap Math permanently, or end your account for a reason other than your breach of the Terms of Service, before the Premium period you have paid for ends.

We fully refund the affected charge if:

• Duplicate charge: you were charged more than once for the same period.
• Charge after cancellation: you were charged after successfully cancelling your subscription, either in the Stripe portal or by email (see section 3).
• Error on our side: the charge was caused by a technical or billing error on our side.

Examples of an error on our side:

• the amount charged does not match the price of the plan you chose
• you were charged but Premium was not activated, and we could not fix it within a reasonable time after you contacted us
• paid days on a 12-month pass were lost because a Monthly or Yearly subscription replaced them

For duplicate charges, we also cancel the duplicate subscription so no further charges are made.

Any right to a refund you have under the law is in addition to these three situations (see section 12).

Email us at sokongan@mantapmath.app and include:

• your parent account email
• the date of the charge
• the amount charged
• a short reason, for example “charged twice”

You can find the date and amount of the charge on your receipt (see section 9). We will reply within 3 working days.

Approved refunds are returned through Stripe to your original payment method and may take 5 to 10 working days to appear in your account, depending on your bank or card issuer.

At the start of each new billing period, we charge your saved payment method through Stripe until you cancel.

If a renewal payment fails, Stripe will retry it and Premium stays active during the retry period. If the payment still fails in the end, the subscription ends and your account returns to the free plan. Your children's profiles and progress records stay in the account.

To avoid a failed payment, make sure your saved card is still valid and update it if needed.

Subscription receipts and invoices can be viewed in the Stripe customer portal through Kawasan Ibu Bapa (Parent Area) → Akaun (Account) → Urus Premium (Manage Premium) → Urus langganan · resit · tukar kad (Manage subscription · receipts · change card), where you can also change your card.

After Premium has ended, past receipts can still be viewed through the Lihat resit lama (View past receipts) link on the Premium page. If you cannot find a receipt, email sokongan@mantapmath.app and we will send you a copy.

We may change our prices from time to time. New purchases are charged at the price shown when you pay.

If you are an existing subscriber, we will email you at least 30 days before a new price applies at your next renewal. You can cancel before the new price applies, and you will not be charged the new price.

The price you have already paid for your current period, including a 12-month pass, does not change. We will not reduce Premium benefits during a period you have already paid for.

Please contact us at sokongan@mantapmath.app first, before raising a dispute or chargeback with your bank. This request does not take away your right to contact your bank.

We can check your payment records and refund charges that qualify under this policy directly through Stripe.

This policy does not affect your rights as a consumer under Malaysian law, including the Consumer Protection Act 1999, which cannot be excluded by agreement. If any part of this policy conflicts with those rights, your statutory rights apply.

You may also file a claim with the Tribunal for Consumer Claims Malaysia (Tribunal Tuntutan Pengguna Malaysia, TTPM) or take the matter to the courts of Malaysia.

We may update this policy from time to time. The latest version is always shown on this page with its effective date.

For important changes, we will email parents who have accounts before the changes take effect.

Changes do not affect your rights relating to payments made before the change takes effect, and do not reduce Premium benefits during a period you have already paid for.

This version applies from 22 September 2026.

This policy is provided in Bahasa Melayu and English. If the two versions conflict, the Bahasa Melayu version prevails. Users who choose the Chinese interface are shown the English version.
