Privacy Policy



Last Updated: August 11, 2026

This Privacy Policy describes how Suzhou Vision Unlimited Technology Co., Ltd., operating under the brand Dovarlin™ (“Dovarlin™,” “we,” “us,” or “our”), collects, uses, discloses, and retains personal information when you visit our website, make a purchase, create an account, contact customer service, or otherwise interact with our online store.

Our store is hosted through Shopify. Depending on the service involved, Shopify and other providers may process personal information on our behalf or for purposes described in their own privacy notices.

4. How We Disclose Personal Information

We may disclose personal information to providers that help us operate the store and complete customer transactions.

Commerce and Website Providers

Shopify hosts our online store and supports functions such as checkout, account management, analytics, and store administration.

Shopify may process information as a service provider on our behalf. For certain Shopify services, it may also process information for purposes described in the Shopify Consumer Privacy Policy.

Payment Providers

Payment providers process transactions, verify payment methods, conduct fraud screening, and manage payment disputes.

Fulfillment and Delivery Providers

We may provide names, addresses, telephone numbers, order information, and delivery instructions to warehouses, fulfillment partners, customs agents, and shipping carriers.

Store Operations Providers

Information may be disclosed to providers assisting with:

  • Website hosting and maintenance

  • Customer-service management

  • Email delivery

  • Data storage

  • Order administration

  • Fraud detection

  • Performance measurement

  • Accounting or legal services

These providers are permitted to process information for the services they provide and as otherwise allowed by applicable law.

Advertising and Analytics Partners

Subject to your preferences and applicable law, we may allow advertising, analytics, and social-media partners to collect information through cookies or similar technologies.

These partners may include:

These companies may combine information collected from our website with information obtained through other websites, applications, devices, or services.

Corporate Transactions

Personal information may be disclosed during a merger, acquisition, financing transaction, restructuring, asset transfer, or similar business event. Any recipient will be expected to handle the information in accordance with applicable law.

Legal and Protective Disclosures

We may disclose information when reasonably necessary to:

  • Comply with a court order, subpoena, or lawful government request

  • Enforce our agreements and store policies

  • Investigate suspected unlawful conduct

  • Protect the rights, property, and security of customers, the Company, or others

  • Establish or defend legal claims

5. Sale, Sharing, and Targeted Advertising

Dovarlin™ does not sell personal information in exchange for direct monetary payment.

However, certain advertising and analytics activities may be classified as a “sale,” “sharing,” or use for “targeted advertising” under some U.S. state privacy laws. This may occur when cookies, pixels, or similar technologies provide identifiers or browsing activity to advertising partners.

Where these laws apply, you may have the right to opt out through:

  • The privacy or cookie controls displayed on our website

  • A “Your Privacy Choices” or comparable opt-out page, when available

  • A recognized Global Privacy Control signal

  • An email request sent to service@dovarlin.com

Your choice may apply only to the browser and device used to submit it. If you clear cookies or use another browser or device, you may need to renew your preference.

We do not knowingly sell or share personal information belonging to individuals under 16 for targeted advertising purposes.

6. Cookies and Similar Technologies

Cookies are small data files placed on a browser or device. We and our providers use cookies and comparable technologies to operate the website, remember selections, understand store activity, and support advertising.

Essential Cookies

These cookies support functions such as:

  • Shopping carts

  • Checkout

  • Account authentication

  • Fraud prevention

  • Privacy selections

  • Website security

Because these technologies are required for core store functions, they may not be fully disabled through our cookie controls.

Functional Cookies

Functional cookies remember choices such as language, region, login status, or other store preferences.

Analytics Cookies

Analytics technologies help us understand how visitors use the store, which pages receive traffic, and where technical improvements may be needed.

Advertising Cookies

When enabled, advertising cookies may be used to measure campaigns, understand engagement, create advertising audiences, and display advertisements on other services.

Where required, non-essential cookies will be used only after the relevant permission has been obtained.

You can manage cookies through our website controls and your browser settings. Blocking certain cookies may affect account access, checkout, saved carts, or other website features.

More information about cookies used through Shopify is available in the Shopify Cookie Policy.

7. Browser Privacy Signals

Some browsers provide a “Do Not Track” setting. Because there is no single industry standard governing all Do Not Track signals, our website may not respond to ordinary DNT settings unless required by applicable law.

Where legally required, we recognize qualifying opt-out preference signals, including Global Privacy Control, as a request to opt out of activities considered a sale or sharing of personal information or targeted advertising.

8. Data Retention

We retain personal information only for as long as reasonably needed for the purposes described in this Privacy Policy.

Retention periods may depend on:

  • The duration of your customer relationship

  • Order fulfillment and customer-service needs

  • Tax, accounting, and financial-record requirements

  • Fraud-prevention and store-security needs

  • Warranty, refund, or dispute periods

  • Applicable limitation periods

  • Legal or regulatory obligations

When information is no longer reasonably required, we may delete, anonymize, or securely isolate it, subject to legal and technical limitations.

9. Information Security

We use administrative, organizational, and technical measures designed to protect personal information from unauthorized access, alteration, loss, misuse, or disclosure.

These measures may include encrypted transmission, access restrictions, account controls, service-provider reviews, and monitoring for suspicious activity.

No website, database, or transmission method can be guaranteed to eliminate every risk. Customers should use unique passwords, protect account credentials, and avoid sending confidential payment information through ordinary email.

If a security incident affects personal information, we will investigate and provide notices when and as required by applicable law.

10. International Data Transfers

Dovarlin™ serves customers and works with service providers in multiple locations. As a result, personal information may be processed or stored outside your state, province, or country.

Privacy and data-protection laws in those locations may differ from the laws where you live. When required, we use contractual or other recognized safeguards for international transfers.

Shopify and other providers maintain their own international transfer arrangements, as described in their respective privacy notices.

11. Your Privacy Rights

Depending on your location and subject to legal exceptions, you may have the right to:

  • Request access to personal information we maintain about you

  • Obtain a copy of certain information

  • Correct inaccurate information

  • Request deletion

  • Restrict or object to certain processing

  • Withdraw consent

  • Opt out of targeted advertising

  • Opt out of activities considered a sale or sharing

  • Request data portability

  • Appeal the denial of a qualifying request

  • Lodge a complaint with a privacy or data-protection authority

You may exercise an applicable right by contacting service@dovarlin.com.

Please describe your request and provide enough information for us to locate the relevant records. We may need to verify your identity before completing a request. Verification may involve confirming account, order, or contact information already associated with you.

We will use information submitted for verification only to assess and respond to the request.

Where permitted, an authorized agent may submit a request on your behalf. We may ask for evidence of the agent’s authority and may contact you directly to confirm the request.

We will not unlawfully discriminate against you for exercising an available privacy right.

12. California and Other U.S. State Disclosures

Residents of California and certain other U.S. states may have additional rights regarding access, correction, deletion, portability, targeted advertising, and the sale or sharing of personal information.

During the relevant period, we may collect and disclose the following categories for the business purposes described in this policy:

  • Identifiers, such as names, email addresses, IP addresses, and account identifiers

  • Customer-record information, such as billing and delivery details

  • Commercial information, such as purchases, returns, and product interests

  • Internet activity, such as browsing, cart, and website interaction data

  • Approximate location derived from IP address

  • Inferences concerning likely preferences or interests

  • Communications and customer-service records

These categories may be disclosed to Shopify, payment providers, delivery providers, fraud-prevention services, analytics providers, advertising partners, and professional advisers.

We do not use or disclose sensitive personal information for purposes that require a separate right to limit under California law unless our practices change and an appropriate notice is provided.

13. European Economic Area, United Kingdom, and Switzerland

Where applicable, individuals in the European Economic Area, United Kingdom, or Switzerland may request access, correction, deletion, restriction, portability, or objection concerning their personal information.

You may also withdraw consent and lodge a complaint with your local supervisory authority.

Some requests may be limited when processing is required to complete a transaction, comply with law, protect legal rights, or meet another recognized legal basis.

14. Children’s Privacy

Our store is intended for a general audience and is not directed toward children under 13.

We do not knowingly collect personal information directly from children under 13. If you are a parent or guardian and believe a child has submitted personal information to us, please contact service@dovarlin.com so we can review the situation and take appropriate action.

15. Marketing Communications

If you subscribe to promotional messages, we may send information about products, offers, or store updates.

You may unsubscribe from marketing emails by:

  • Selecting the unsubscribe link in a promotional email

  • Updating available account preferences

  • Contacting service@dovarlin.com

Unsubscribing from marketing does not prevent us from sending transactional communications, including order confirmations, delivery updates, refund notices, or responses to customer-service requests.

We do not use deceptive sender information or misleading subject lines in promotional communications.

16. External Links

Our website may contain links to social networks, payment services, or other third-party websites.

These services operate under their own privacy policies. We are not responsible for how an independent third party collects or uses information after you leave our website.

We encourage you to review the privacy notice of any external service before providing personal information.

17. Changes to This Privacy Policy

We may revise this Privacy Policy to reflect changes in our store practices, technology, service providers, or legal obligations.

The updated version will be posted on this page with a revised “Last Updated” date. If required by law, we will provide additional notice before a material change takes effect.
