Privacy Policy

Effective October 20, 2026. Hangzhou Yunteng Yisheng Network Technology Co., Ltd., trading as Pervanzo, is responsible for the personal information described in this policy. Our contact details appear below.

Information we collect and where it comes from

You may provide your name, delivery and billing details, email, telephone number, order information and messages when you shop or contact us. Shopify, payment providers and delivery services may provide transaction status, fraud signals, delivery updates and support records. Our storefront and service providers may collect device, browser, network, cookie and interaction information needed to operate and improve the store.

How we use information

We use information to process orders and payments, arrange delivery and returns, respond to requests, protect against fraud, maintain records, meet legal obligations and understand store performance. Where you choose to subscribe, we use your contact details for marketing and honor unsubscribe requests. We do not need full payment card details in a customer support message.

Service providers and other disclosures

Shopify hosts our store and processes information to provide its services. Payment processors, shipping providers, support services and professional advisers may receive the information needed for their work. We may disclose information to comply with law, protect rights and security, or handle a business transaction subject to applicable safeguards. Any advertising or analytics feature must operate subject to applicable privacy settings and consent requirements; this policy does not claim that a particular advertising pixel is installed.

Cookies and marketing choices

Essential technologies support shopping, security and checkout. Other technologies may support analytics or marketing where enabled and permitted. You can use available store privacy controls, browser settings and marketing unsubscribe links. Blocking essential cookies can affect checkout and account features. For available opt-outs or privacy requests, visit Your Privacy Choices or email us.

Retention, security and international handling

We retain information as needed for the purpose collected, order and tax records, dispute resolution and applicable legal requirements. The period depends on the record and obligation. We use reasonable organizational and technical safeguards, but no internet service is completely secure. Our business is based in China and service providers may process data in other countries, including where Shopify operates. Applicable transfer safeguards are used where legally required.

Your rights and requests

Depending on your location, you may have rights to access, correct, delete or obtain a copy of personal data; restrict or object to certain processing; withdraw consent; or opt out of qualifying sale, sharing or targeted advertising. You may use an authorized agent where applicable. Email us with the request and enough information to locate your records. We may verify identity proportionately and explain any lawful limits. We will not discriminate against you for exercising applicable rights. You may raise a concern with us or the competent privacy regulator.

Children and changes

The store is not directed to children, and we do not knowingly request personal information from children. A parent or guardian who believes a child supplied information should contact us. We may update this policy as practices or requirements change, with the effective date shown above.
