Terms of Sale & Refund Policy

Last updated: June 12, 2026

1. Who we are

This website is operated by HERD Pte. Ltd., a private limited company incorporated in Singapore ("HERD", "we", "us"). Contact: wet4kg@gmail.com. Our Unique Entity Number (UEN) will be published on this page.

2. What we sell

HERD One is an infrasound sensor for citizen science, currently in development. We accept pre-order reservations for the first production batch. We also accept voluntary R&D support contributions. We do not currently sell finished, in-stock products.

3. Pre-order reservations

A pre-order reservation costs USD 15 (or THB 199 for residents of Thailand at local pricing) and is a fully refundable deposit.
The deposit reserves one HERD One sensor from the first production batch and a numbered station slot in the HERD network.
Estimated shipping for the first batch: second half of 2026. This date is an estimate, not a guarantee. Specifications may change during development.
Before shipping, we will contact you to confirm your shipping address. No additional amount is ever charged automatically.

Refunds. You may cancel your reservation and receive a 100% refund of your deposit at any time before shipping confirmation — no questions asked. Refunds are issued to the original payment method within 5–10 business days of the request. To request a refund, email us from the address used at checkout.

4. R&D support contributions

R&D support contributions are voluntary payments that support the development of the HERD sensor network by HERD Pte. Ltd., a commercial company.
They are not donations to a charity, not investments, and confer no equity, interest, or tax deduction.
Contributors receive recognition on the project's founders list and quarterly public spending reports.
R&D contributions are non-refundable once spent, but we will honor refund requests made within 14 days of payment.

5. Important product disclaimer

HERD One and the HERD network are research instruments. They are not a certified life-safety device or a guaranteed warning system, and they do not replace official government emergency alert channels. No consumer device available today can guarantee advance warning of a tsunami or volcanic eruption.

6. Shipping

First-batch shipping destinations and costs will be confirmed by email before shipment. If we cannot ship to your country, your deposit will be refunded in full.

7. Payments

Card payments are processed by Stripe. We accept major cards and local payment methods where available. Cryptocurrency contributions (BTC, USDC) are accepted at the company addresses published on our website; for amounts above the equivalent of USD 1,000 we may request identity verification.

8. Privacy

We collect your email address and, later, your shipping address — solely to manage your reservation. We do not sell or share your data with third parties for marketing. Sensor telemetry in the HERD network is open data by design and contains no personal information beyond the station name you choose.

9. Governing law

These terms are governed by the laws of the Republic of Singapore.
