Scope

This policy explains how we collect, use, disclose, retain, and protect personal information when you visit hemopow.com, contact us, or later place an order after checkout is enabled.

Information we collect

Depending on how you interact with us, we may collect contact details; account and order information; payment and transaction details handled by payment providers; shipping and return information; customer-service communications; device, browser, IP address and usage data; cookie and preference data; and information you voluntarily provide in a review or survey.

How we use information

We use personal information to operate and secure the site; provide products and support; process payments, orders, shipping, returns, refunds and fraud checks when sales open; communicate with you; comply with law; maintain records; improve our services; and send marketing only where permitted and consistent with your choices.

How we disclose information

We may disclose information to Shopify and service providers that support hosting, payments, fraud prevention, fulfillment, carriers, customer support, analytics, security, legal compliance and professional advice. We may also disclose information in a business transaction or when required by law. We do not knowingly sell personal information for money. If any disclosure is treated as a sale or sharing under applicable law, eligible visitors may opt out through the Your privacy choices link.

Cookies and privacy choices

We and our providers may use cookies or similar technologies that are necessary for security and site operation, and - subject to applicable consent requirements - for preferences, analytics or marketing. Use the cookie banner and Your privacy choices link to manage available choices. We honor legally recognized opt-out preference signals where required.

Retention and security

We retain personal information only as long as reasonably needed for the purposes described above, including legal, accounting, tax, fraud-prevention and dispute requirements. We use reasonable administrative, technical and organizational safeguards, but no system is completely secure.

Children

Our site is intended for adults. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and delete it as appropriate.

Your rights

Depending on where you live, you may have rights to request access, correction, deletion or a copy of personal information, and to limit or object to certain processing. California residents may also have rights to know, delete, correct, opt out of sale or sharing, limit certain uses of sensitive personal information, and receive equal service without unlawful discrimination. To submit a request, email support@hemopow.com. We may verify your identity and may accept requests through an authorized agent as required by law.

International processing

Our company is based in China and our providers may process information in the United States and other countries. Where required, we use appropriate safeguards for cross-border transfers.

Changes and complaints

We may update this policy when our practices or legal obligations change and will post the revised effective date. Questions, requests, or complaints may be sent to support@hemopow.com or made by phone at +1 (833) 228-2278.
