Terms of Use

Updated: {{policyUpdatedDisplayEn}} · Applies to every transaction at https://sonvudev.com

You are reading the terms that apply when you buy and use software developed by SonVuDev. Placing an order means you accept the terms below. If you do not agree, please do not proceed with the transaction.

1. Who may use it

The licence you buy is a personal, non-transferable licence, for one computer belonging to one user. You may not resell, share, rent, sublet or redistribute the copyright, the source code or the release file in any form, even if you have edited the source code.

You may use it for internal business purposes, but the software runs only on computers owned by that organisation and may not be redeployed as a service. Licences for a whole team, or for several machines, need a separate package, so please contact us before you buy.

2. Payment methods

We take payment through PayPal (VND converted to USD at the rate that applies when the order is created) and by bank transfer, MoMo or ZaloPay. The listed price is the amount you pay; any fee charged by a third party is not part of it.

With PayPal, the exchange rate is recorded on the order the moment it is created and does not change afterwards. With a bank transfer, please leave the amount and the transfer note exactly as we filled them in, so that we can match the payment.

Bank transfer orders are confirmed during business hours, usually within 24 hours. Until then the order status is awaiting bank transfer and the file cannot be downloaded yet.

3. Payment window and cancellation

Unpaid orders are automatically cancelled after 24 hours from the moment you place the order, applying to all payment methods. This deadline is shown on the checkout form and on your order page.

We send a reminder email before the window closes. If the money reaches our account after an order has already been cancelled — because PayPal reported success late, say — the order is reopened and you can still download the product. If you paid by bank transfer after the window had closed, send us the receipt and we will match it or hand the money back.

4. Delivery and download

Once your bank transfer order is confirmed or PayPal reports success, you receive your order lookup code. That code is the only way into the release file, so keep it somewhere safe. We also email it to you together with the payment window.

Every download creates a short-lived link, and you can create a new one at any time with your lookup code. A download link works once and may be withdrawn for security reasons.

An order counts as finished as soon as you start the download, and the download button locks again. That way each order releases the file exactly once. If the download fails because of the network, or the file arrives damaged, get in touch and we will reopen the order for you.

The downloaded file keeps the name of the release (for example SparkCapacityTester.exe). Some antivirus programs or browsers may warn about an unsigned executable; that is normal behaviour for software downloaded straight from the internet, and not a sign of malware.

5. A permanent licence, no recurring fee

The price you pay is for the version you bought, for good. There is no subscription fee, no maintenance fee and no charge to renew the licence. Future updates in the same product line are released free whenever there are any.

6. Warranty and support

We warrant that the software runs as described on the system requirements we state. If it does not, you get your money back or an equivalent fixed release; you choose which one. Technical support is answered by email within 2 business days.

We do not warrant that the software works on every system configuration, on every version of Windows, or with antivirus software that blocks executables. You are responsible for backing up your data before installing any tool.

7. Refunds

Your right to a refund, and the conditions that apply, are set out in the refund policy. In short: you get a refund if the software does not work as described, and you do not if you have already put it to normal use after downloading it.

8. Limitation of liability

To the fullest extent the law allows, our liability for any claim is limited to the total amount you paid for that order. We are not liable for indirect damage, for lost data, or for lost profit arising indirectly from the use or non-use of the software.

9. Suspension of the licence

The licence is void if you break these terms, and sharing, redistributing or reselling the software counts as breaking them. In that case we may refuse to issue download links for the orders under that licence. We may also stop providing the service if you use it to harm other people or to break the law.

10. Changes to these terms

We may update these terms. An update takes effect from the moment it is published on this page and does not apply retroactively to orders already placed: each order is governed by the terms in force at the moment you bought.

11. Governing law and disputes

These terms are governed by and construed in accordance with the laws of Vietnam. Disputes will be resolved through good-faith negotiation first; if no agreement is reached, either party may refer the matter to the competent court where SonVuDev is based.
