Payment and service policy
Effective 13 November 2026.
This policy covers every VIP purchase on vimai.jp and the ViMai web apps on *.vimai.jp. Seller: Phạm Tiến Việt, tax code 024088015220.
1. Prices
Web payment by Vietnamese bank transfer is offered on the Vietnamese version of the apps. On the English and Japanese versions, please buy VIP in the iOS app; Apple shows the price. Tiếng Việt
2. Payment methods
Bank transfer (VietQR): the payment screen shows a VietQR code with the receiving account, the amount and a transfer note unique to your order. Scan it in your banking app and keep the amount and note unchanged. In-app purchase (App Store): Apple charges you and shows the price in your local currency, under Apple's terms. ViMai never collects your card number, banking password or OTP, and nobody from ViMai will ask for them.
3. Buying and activation
1) Choose a VIP plan in the app and enter a referral code if you have one. 2) Scan the VietQR code and transfer the exact amount with the exact note. 3) The system matches the payment with the bank automatically and activates VIP, usually within 1–2 minutes. 4) If VIP is not open after 30 minutes, or you sent a wrong amount or note, send a photo of your transfer receipt by email or Zalo and we will activate it by hand.
4. Service delivery
VIP is digital content delivered online inside the app; there is no shipping. The plan period starts at activation. When it ends, the app returns to the free version; your study progress is kept.
5. Proof of payment
Your bank's transfer receipt is the proof of payment. If you need a written confirmation from ViMai, send the time and amount of the transfer.
6. Supporting ViMai
Some apps have a Support button. A donation is voluntary and is not a purchase; the thank-you gift (a discount code) follows the levels shown on the button. If you sent money by mistake, contact us for a refund.
