Effective date: 2026-11-04
These terms apply to licenses for the Hiraishin Chrome extension purchased on or after the effective date. They do not limit your statutory rights.
Hiraishin is sold and provided by 44san, a sole proprietor in Japan. The seller is responsible for the product, license delivery and product support. Google is not the seller and does not handle payments or refunds for this product.
For product, license or refund questions, use the contact form. Include an email address where we can reply and your order reference or payment email address. Do not send a full card number, security code or account password.
You are purchasing a license to use the Hiraishin Chrome extension. This is a one-time payment, with no subscription or automatic renewal charges. All prices include tax; the price shown is what you pay at checkout.
| Payment currency | Price from February 1, 2027 (tax included) | Launch price (tax included) |
|---|---|---|
| US dollars | US$9.90 | US$6.00 |
| Japanese yen | JPY 1,400 | JPY 900 |
The launch price runs until January 31, 2027, 23:59 Japan Standard Time and is applied automatically on the checkout page opened from the extension's purchase button. You pay in only the currency selected at checkout; depending on your region, checkout may show the amount converted to your local currency. The total is shown before you confirm payment. If checkout differs from these prices, contact us before purchasing.
Every feature is free to try for 14 days, starting with your first successful action. The trial does not require a payment card and does not automatically charge you when it ends. You decide whether to purchase afterwards.
Once payment is confirmed, a license key is issued automatically and immediately, and provided on the payment-completion page and in the extension's settings. Contact us if the key does not appear or activation fails. Your rights concerning non-delivery are not limited by the refund period below.
Copy the key or download a backup. You can use it to restore your purchase after reinstalling the extension or changing computers. Please do not publish or resell your key. Activation, recovery and periodic license verification require an internet connection. While temporarily offline, you can keep using the extension within the validity of your cached license.
You may request a full refund for any reason within 14 days after payment is completed. This period is counted separately from the 14-day free trial, and you do not need to prove that the product was unused. Submit your request through the contact form above within that period, with your order reference or payment email address.
After 14 days, issues such as non-delivery, a material difference from the product description, duplicate charges or unauthorized payments may still qualify for a refund or other remedy under applicable law and the payment provider's policies. This refund policy does not limit statutory rights or other rights under the Sold through Link terms or refund policy.
Refunds are processed through the original payment method. The time until funds arrive depends on the payment provider and bank. Once a full refund is completed, the license for that purchase is revoked, and the extension updates its status at its next license verification.
Payments are made through Stripe Managed Payments (Sold through Link) and are also subject to the Link consumer terms and the Sold through Link refund policy. For payment, receipt and transaction-refund questions, you can also contact Sold through Link support. How payment-related data is handled is described in Privacy and data.
Chrome 121 or later is required. The in-page wheel cannot run on restricted pages such as Chrome's internal pages or the Chrome Web Store. Sending to AI requires your own account with the AI service, and the target page must be compatible with the product. Your purchase does not include accounts, subscriptions or fees for ChatGPT, Claude or other third-party services.
Third-party website changes can affect compatibility, so use the free trial to check your actual workflow. "One-time purchase" describes the pricing model, a single payment; it does not promise lifetime updates, perpetual online availability or free access to every future product. This does not reduce your rights under applicable law or the product description at purchase.
