Privacy policy
川口精研株式会社 (“we”) handles your personal information on the JPHEAT official site (jpheat.jp) as follows.
1. What we collect
Inquiries: name, email address and message. Orders: name, address, phone number, email address and order details. Payment information is handled by the payment service (such as Shopify Payments), and we keep no card numbers.
2. Purpose of use
Shipping and payment, answering inquiries, warranty service and important product notices. No other purpose.
3. Third parties and outsourcing
Except as required by law, we do not share personal information with third parties without your consent. We outsource shipping and payment to delivery and payment companies (including companies in Japan and Singapore) as needed, under appropriate supervision. As we use Shopify Inc. (Canada) for payments and orders and Google LLC (United States) for analytics, personal information may be transferred to those countries. Please ask us about the data protection systems of those countries and the measures each company takes.
4. Cookies and analytics
This site uses cookies to keep your cart and make the site better, and an analytics tool (Google Analytics 4). Analytics data alone cannot identify you, but referrer and ad identifier data is handled with your order information at purchase. Your browser also stores which page or ad brought you here (referring site, ad identifier and first page viewed) for up to 90 days, and passes it to the Shopify checkout as part of your order information when you proceed to purchase, and at no other time. You can turn off cookies in your browser settings, or stop analytics with the opt-out add-on from Google.
5. Retention and security
We keep data as long as the purposes of use require, then delete it appropriately. Security measures: internal handling rules (organizational), staff training (human), document and equipment storage control (physical), access control and encryption (technical).
6. Disclosure, correction, stopping use
After confirming your identity, we promptly handle requests to disclose, correct, add, delete, stop using or stop sharing your personal information with third parties. No fee.
7. Laws and revisions
We observe the Act on the Protection of Personal Information and related laws and guidelines. This policy may be revised as needed, and revisions apply once posted on this page.
