PRICING POLICY
Last updated: August 18, 2026
This Pricing Policy (the “Policy”) sets out how KOKI SOFTWARE COMPANY LIMITED (“Koki”, “we”) lists, determines, and applies prices for Koki Premium plans and other products and services sold directly on the koki.vn website.
This Policy applies to purchases made directly on the koki.vn website. Transactions made through the Apple App Store or Google Play are governed by Section 7 below.
1. Currency, taxes, and other charges
All prices on the koki.vn website are listed in Vietnamese Dong (VND).
The listed price is the total amount Koki collects for the corresponding service plan and includes any taxes, fees, and charges that Koki is obliged to include in the sale price (if any) under Vietnamese law.
Koki does not collect any mandatory surcharge beyond the amount shown to the buyer before the order is confirmed, unless clearly notified before the buyer places the order and in accordance with the law.
Koki Premium is supplied in electronic form, so no shipping charges arise.
Where the buyer's bank or payment service provider charges a transfer fee, a transaction fee, or a similar fee, that fee:
- Is set by the bank or payment institution
- Is not a fee collected by Koki
- Is not included in Koki's listed sale price.
2. Current price list
The detailed price of each Koki Premium plan is published on the Pricing page of the koki.vn website.
For each service plan, Koki may publish information such as:
- The plan name
- The price
- The term of use
- The scope of entitlements or features
- The conditions of application
- Any promotional programme currently in force.
Before the buyer confirms the creation of an order, Koki displays the applicable price and the total amount the buyer must pay.
The price of a transaction is determined by the information shown at the order confirmation step, after any valid promotions, discounts, or offers have been applied.
Where there is a discrepancy between promotional content shown elsewhere on the website and the price displayed at the order confirmation step, Koki will review and resolve the matter to ensure the buyer is clearly informed before paying.
3. When the price is fixed, and order validity
The price applicable to an order is the price displayed at the moment the buyer confirms the creation of the order.
An unpaid order is valid for 7 days from the time the order is created, unless a different period is stated on the order.
3.1. Where the listed price increases
If the listed price of the same service plan increases while the order is still valid, the buyer may still pay at the price recorded on the order.
3.2. Where the listed price decreases
If the listed price applicable to the same service plan on the same purchase conditions decreases before the order is paid, Koki will ensure that the amount payable by the buyer is no higher than the price in force at the time of payment.
Where necessary, Koki may:
- Adjust the amount of the order; or
- Ask the buyer to create a new order at the current price.
3.3. Expired orders
If an order remains unpaid after the 7-day period, the order expires.
The buyer will need to create a new order, and the applicable price will be the price in force at the time the new order is created.
4. Price adjustments
Koki may adjust the prices of its service plans from time to time, consistent with its business operations and with the law.
When a price is adjusted:
- The price list on the website is updated accordingly
- The new price applies to orders created after the new price takes effect, except in the cases set out in Section 3
- A price adjustment does not change the term of use or the entitlements of a Premium plan that the buyer has already paid for and activated, unless otherwise agreed with the user or required by law.
Koki does not collect further money for a service plan that has been paid in full merely because the listed price of that plan increases after payment.
5. Promotions, discounts, and offers
Koki may run programmes involving:
- Promotions
- Discounts
- Promotional codes
- Preferential prices for certain groups of users
- Programmes granting additional term of use
- Other forms of offer consistent with the law.
Where a programme applies, Koki will publish or display the necessary information before the buyer confirms the order, depending on the nature of the programme, including:
- The price or the level of the offer
- The period of application
- The service plans covered
- Who is eligible
- The conditions for using a promotional code, if any
- Any other relevant limits or conditions.
The final price after any valid offers have been applied is displayed to the buyer before the order is confirmed.
Unless Koki states otherwise for a specific programme, promotional programmes and promotional codes cannot be combined with one another.
Where a promotional programme has its own conditions, those conditions apply together with this Policy.
6. Pricing errors
Koki endeavours to ensure that pricing information on the website is displayed accurately.
However, where a technical fault, data-entry error, or system error causes a price to be displayed that is clearly incorrect, Koki may:
- Notify the buyer of the error
- Correct the information displayed
- Ask the buyer to reconfirm the transaction at the correct price
- Cancel an unpaid order where necessary.
If the buyer has already paid and Koki discovers a pricing error, Koki will contact the buyer and handle the matter in accordance with the law, safeguarding the buyer's lawful consumer rights.
Koki does not rely on these pricing-error provisions to increase the price of a transaction that has been validly confirmed and paid in full, except where permitted by law or otherwise lawfully agreed between the parties.
7. Prices on the Apple App Store and Google Play
Users may purchase Koki Premium directly in the app through the Apple App Store or Google Play where Koki makes that purchase method available.
The price, currency, taxes, and payable amount shown for an in-app transaction are determined by the App Store's or Google Play's own mechanisms in the relevant country or region.
Accordingly, the price of Koki Premium on the App Store or Google Play may differ from the price sold directly on the koki.vn website.
Such differences may arise from:
- The platform's price-setting mechanism
- The currency
- Exchange rates
- Taxes applicable in each country or region
- The platform's policies
- Other factors within Apple's or Google's operating mechanisms.
This Pricing Policy governs purchases made directly on the koki.vn website.
For transactions made through the App Store or Google Play, users are additionally subject to the terms and to the payment, invoicing, and refund policies of the relevant platform.
8. Electronic invoices
Koki issues electronic invoices for transactions that require an invoice under the law on taxation, accounting, and electronic invoicing.
If the buyer requires an invoice showing the details of a business, organisation, or unit, the buyer should provide complete and accurate invoicing information during the ordering process or before the invoice is issued.
The information may include:
- The name of the entity
- The tax identification number
- The address
- The email address to receive the invoice
- Other information required under the electronic invoicing rules.
The buyer is responsible for ensuring that the information provided to Koki is accurate.
Where an invoice has already been issued but the information needs to be adjusted or replaced, Koki will handle the matter in accordance with the electronic invoicing rules in force at the time of the request.
Any invoicing request may be sent to:
Email: [email protected]
9. Payment, refunds, and service termination
This Policy governs the listing and application of prices.
Matters relating to:
- Payment methods
- Payment confirmation
- Transaction reconciliation
- Cancellation of transactions
- Service termination
- Refunds,
are governed by the corresponding policies Koki publishes on the koki.vn website and by the law.
Where a promotional programme or offer carries its own refund conditions, those conditions will be notified to the buyer before the transaction is confirmed.
10. Feedback, requests, or complaints relating to prices
If a user has a question, feedback, or a complaint relating to:
- The listed price
- The price applied to an order
- Promotions or promotional codes
- A pricing discrepancy
- Taxes, fees, or the total amount payable
- Invoices
- Other matters relating to this Policy,
the user may contact Koki at:
Email: [email protected]
Feedback, requests, and complaints are received and handled in accordance with the Methods for Receiving and Resolving Feedback, Requests, and Complaints published by Koki on the koki.vn website.
11. Changes to this Pricing Policy
Koki may update this Policy where:
- The price structure or the service plans change
- A new sales programme is introduced
- The transaction methods change
- Legal requirements change
- There is another reasonable ground relating to the provision of the Services.
The latest version of this Policy will be published on the koki.vn website and will state the date of the update.
An update to this Policy does not change the price of transactions completed before the new policy takes effect, unless the law provides otherwise.
