Privacy Policy

Last Updated: October 23, 2026

At DFHEU™, operated by Suzhou Fengruihe Information Technology Co., Ltd., we understand that protecting personal information is an important part of providing a reliable online shopping experience. This Privacy Policy explains the types of information that may be collected when you visit dfheu.com, place an order, or contact our team, as well as how that information may be used, disclosed, and protected.

By using our website, you acknowledge that you have had the opportunity to review this Privacy Policy. Where applicable law requires consent for specific data collection or processing activities, we will seek that consent as required.

1. Information We Collect

The information we collect depends on how you interact with our website and which services you choose to use.

Information You Provide Directly

When you make a purchase, submit a form, or contact our customer support team, we may collect information such as:

• Name and contact information, including email address and telephone number.

• Shipping address, billing address, and other delivery details.

• Order information, including purchased products, quantities, transaction references, and order history.

• Information included in messages, feedback, or customer service requests.

• Marketing preferences and newsletter subscription choices, where applicable.

Payment-Related Information

When you pay for an order, payment details are handled through the payment methods and service providers available at checkout. Depending on the payment method, we may receive transaction confirmations, payment status, and limited payment-related information necessary to administer your order.

Please do not send full payment card numbers, card security codes, passwords, or other sensitive financial credentials through ordinary email.

Information Collected Automatically

When you browse our website, certain technical information may be collected automatically, depending on the website features and technologies enabled. This may include:

• IP address and approximate location derived from technical information.

• Browser type, operating system, device type, and related identifiers.

• Pages viewed, referring websites, and interactions with website features.

• Cookie identifiers and similar online tracking information.

We use this information as appropriate to operate the website, understand site performance, support security, and improve the shopping experience.

2. How We Use Your Information

Personal information may be used for legitimate business purposes associated with operating our store and assisting customers.

Order Processing and Fulfillment

We use relevant contact, order, and delivery information to process purchases, confirm transactions, coordinate shipping, provide order updates, and respond to delivery-related questions.

Customer Service

Information you provide helps us investigate order issues, answer product questions, review return requests, and communicate with you about matters related to your purchase.

Website Operations and Improvement

Technical and usage information may help us understand how visitors navigate the website, identify technical problems, improve page performance, and make product information easier to access.

Marketing and Communications

Where permitted by law and consistent with your preferences, we may use your contact information to send promotional messages, product announcements, or store updates. You may opt out of marketing communications as described in this policy.

Security and Legal Obligations

Information may be used to help detect suspicious transactions, investigate potential misuse, maintain appropriate business records, protect the rights of our business and customers, and comply with applicable legal requirements.

We seek to use personal information only for purposes that are relevant to the circumstances in which it was collected or otherwise permitted by law.

3. Data Security

DFHEU™ recognizes the importance of handling customer information responsibly. We use appropriate administrative, technical, and organizational measures intended to help protect personal information against unauthorized access, disclosure, alteration, or loss.

Our approach may include:

• Controlled Access: Limiting access to personal information to individuals and service providers who need it for relevant business purposes.

• Service Provider Protections: Using website, payment, and other service providers whose services support the operation of our store.

• Secure Transactions: Relying on the security features made available by our website platform and applicable payment providers during checkout.

• Responsible Handling: Taking reasonable steps to manage customer information in accordance with applicable privacy and security requirements.

Payment processing and the protection of payment credentials depend in part on the payment provider and checkout configuration used for a transaction. We do not ask customers to send complete payment card details through ordinary customer service email.

No website, transmission method, or electronic storage system can be guaranteed to be completely secure. We therefore cannot promise absolute security, but we aim to apply safeguards appropriate to the nature of the information and the services provided.

4. Sharing with Third Parties

We may disclose personal information to third parties when reasonably necessary to operate our store, fulfill customer requests, or meet legal obligations.

Categories of recipients may include:

• E-commerce and Hosting Providers: Services that support website operation, shopping cart functionality, order management, and store administration.

• Payment Providers: Companies that process payments, verify transactions, or help address payment disputes.

• Shipping and Fulfillment Providers: Services involved in delivering purchases and providing shipment-related updates.

• Customer Support and Business Service Providers: Providers that help manage customer communications, technical operations, or business administration.

• Analytics and Advertising Partners: Services that may help us understand website activity or deliver marketing, depending on the tools enabled and applicable consent requirements.

• Legal or Regulatory Authorities: Parties receiving information where disclosure is required by law or is reasonably necessary to protect legal rights, investigate suspected fraud, or address security concerns.

We do not sell personal information in exchange for monetary payment. However, certain disclosures to advertising or analytics partners may be treated as a “sale” or “sharing” under particular privacy laws, even when no money changes hands. Where applicable, we will provide the rights and choices required by law.

Advertising & Marketing:

If advertising or analytics technologies are enabled on our website, third-party services may use cookies, pixels, or similar technologies to receive information about website activity. Depending on the configuration, this may help measure advertising effectiveness or deliver more relevant advertisements.

Potential providers may include:

• Meta, including Facebook and Instagram.

• Google and related advertising or analytics services.

The providers actually used depend on the integrations enabled for our store. Each provider may process information under its own privacy terms. You should review the relevant provider's privacy documentation for details about its practices and available controls.

Where required, we will request consent before enabling non-essential tracking technologies. You may also be able to manage advertising preferences through the relevant provider or applicable privacy controls.

5. Cookies and Tracking

Cookies and similar technologies may be used to help our website function properly and to understand how visitors interact with our pages.

Depending on the technologies enabled, these tools may fall into the following categories:

Necessary Cookies

These support core website functions, such as maintaining shopping cart contents, enabling checkout, and helping the website operate as intended.

Performance Cookies

Where enabled, these help us understand website usage, identify technical issues, and evaluate how visitors interact with different pages.

Marketing Cookies

Where enabled and permitted, these may support advertising measurement, campaign performance analysis, or the delivery of relevant promotional content.

Managing Cookie Preferences

You may be able to control cookies through your browser settings or any cookie preference tool provided on our website. Where required by law, we will provide appropriate consent and preference controls for non-essential technologies.

Blocking certain cookies may affect features such as shopping cart functionality or other parts of the website. The precise effect depends on which cookies are disabled.

6. Third-Party Links

Our website may contain links to third-party websites, payment services, or other external resources for your convenience.

When you leave dfheu.com, the external website's own terms, privacy policy, and security practices may apply. DFHEU™ does not control the content or privacy practices of independent third-party websites and cannot guarantee how those websites handle personal information.

We recommend reviewing the relevant privacy notice before submitting personal information to an external service. The inclusion of a link does not necessarily mean that DFHEU™ endorses every product, service, or statement provided by that third party.

7. California Privacy Rights (CalOPPA)

We aim to provide clear information about our privacy practices and to address applicable privacy requirements, including relevant California privacy laws where they apply.

Depending on your circumstances and the law applicable to your information, you may have rights that include:

• Right to Know or Access: Request information about certain personal information collected about you and how it is used or disclosed.

• Right to Correction: Request correction of inaccurate personal information, where applicable.

• Right to Deletion: Request deletion of eligible personal information, subject to legal exceptions and retention requirements.

• Marketing Choices: Opt out of promotional emails using the unsubscribe instructions provided.

• Advertising Privacy Choices: Exercise applicable rights relating to the sale or sharing of personal information for cross-context behavioral advertising, where such processing occurs and the law grants you that right.

To submit a privacy request, contact us using the details in Section 12. We may need to verify your identity and clarify the scope of your request before responding.

California's Online Privacy Protection Act (CalOPPA) also addresses transparency requirements for online privacy policies. We intend this policy to explain our relevant information practices in an accessible format.

Do Not Track (DNT): Some browsers provide a Do Not Track setting. There is no universally adopted standard for responding to every DNT signal, and the way such signals are handled may depend on the technologies and services used on our website. Where applicable law requires recognition of a particular privacy preference signal, we will handle it in accordance with those requirements.

Privacy rights may be subject to exceptions, verification procedures, and other limitations permitted by law. This section does not create rights beyond those provided by applicable law.

8. Children’s Privacy

DFHEU™ does not knowingly seek to collect personal information directly from children under the age of 13 without the authorization required by applicable law.

Our website is intended for people who can lawfully make purchases or use the services offered. If you are a parent or legal guardian and believe a child has provided personal information to us inappropriately, please contact us using the details in Section 12.

After receiving and reviewing a request, we will take appropriate steps to address the information in accordance with applicable legal requirements.

Where a higher age threshold or additional protections apply under local law, those requirements will govern.

9. Data Breaches

We take reasonable steps to protect personal information and to respond appropriately if we become aware of a suspected or confirmed security incident involving information under our control.

Depending on the nature and circumstances of an incident, our response may include investigating the event, taking measures to contain or address the issue, working with relevant service providers, and assessing any required notifications.

If applicable law requires notification to affected individuals or regulatory authorities, we will provide the required notice within the timeframe and in the manner prescribed by that law.

The information provided in any notice will depend on the circumstances of the incident and may include relevant details about the event, recommended protective steps, and available contact channels.

10. Email Communications

We may use your email address to communicate with you about purchases, order confirmations, delivery updates, customer service requests, and other matters related to our store.

Where permitted and where you have provided the required consent or preference, we may also send promotional emails about products, offers, or store news.

Managing Promotional Emails

You can opt out of marketing communications by using the unsubscribe link included in a promotional email or by contacting us directly.

Opting out of promotional messages does not necessarily stop essential service communications, such as order confirmations or important updates about an existing purchase.

We process unsubscribe requests in accordance with applicable requirements. Please note that it may take a reasonable period for a preference to be reflected across all relevant systems.

11. Your Choices

Depending on the information involved and the law applicable to you, you may have several ways to manage your personal information and communication preferences.

Review or Correct Information

If you believe information associated with your order or customer inquiry is inaccurate, contact us with sufficient details to help us identify the relevant record.

Request Deletion

You may submit a request to delete eligible personal information. Certain information may need to be retained to fulfill an order, maintain required records, resolve disputes, prevent fraud, or meet legal obligations.

Manage Marketing Preferences

Use the unsubscribe link in a promotional email or contact our support team to request that marketing communications stop.

Manage Cookies

Adjust your browser settings or use the cookie preference controls available on our website, where provided. Disabling certain cookies may affect website functionality.
