Privacy policy

This policy explains how Duoduostudy handles personal information through duoduostudy.com, purchases, and customer enquiries. Some practices depend on which website features and services are enabled.

Information involved in shopping and support

Order and support records may include your name, email, telephone number, billing and delivery addresses, purchased items, transaction references, and correspondence. We use payment status and related records to administer purchases and refunds. Checkout payment providers process payment credentials. Do not email full payment card numbers or passwords.

Visits may generate technical information, including IP address, device and browser details, pages viewed, and interactions. Cookies or similar technologies may support checkout, security, and preferences. If customer accounts are offered and you use one, we process the information needed to operate that account.

Purposes and service providers

We use information to process orders, arrange shipping and tracking, respond to questions, manage returns and exchanges, and issue refunds. Records also support accounting, fraud prevention, legal obligations, and dispute resolution.

Hosting, payment, delivery, communications, and support providers may receive information needed for their services. We may disclose relevant records to meet legal requirements or address fraud, security incidents, or legal claims. If a business transfer occurs, information may be transferred with applicable protections and notices.

If analytics tools are enabled, they may measure website use. If advertising tools are enabled, they may use browsing information for advertising or measurement, subject to applicable consent and opt-out requirements. Specific practices depend on the tools in use.

Privacy controls and marketing choices

Browser settings and any available website controls let you manage cookies. Restricting cookies may affect shopping features. Where required, you can choose whether optional tracking is permitted and withdraw consent later.

If we send promotional emails, you may unsubscribe using the message's link or contact us. Order and service communications may still be necessary.

Some advertising disclosures may qualify as a sale or sharing of personal information, or targeted advertising, under state law. Where those practices occur and the law applies, you may opt out. We honor legally required opt-out preference signals, including Global Privacy Control, where applicable.

Retention, security, and transfers

Retention depends on why information was collected, whether an order or enquiry remains open, and applicable accounting, legal, or dispute requirements. We retain information as needed for these purposes and delete or de-identify it when no longer required.

We use reasonable safeguards to protect personal information. Electronic storage and transmission cannot be guaranteed completely secure. Providers may process data outside your state or the United States, where privacy rules can differ. We use transfer protections required by applicable law.

Exercising applicable privacy rights

Depending on your location and applicable law, rights may include access, correction, deletion, a portable copy, withdrawal of consent, and opting out of sale, sharing, or targeted advertising. Other rights may include limiting certain uses of sensitive information and appealing a denied request. Exceptions may require us to retain some records.

Send requests to info@duoduostudy.com. We may verify your identity using information proportionate to the request. Authorized agents may act where permitted, with verification of their authority. We respond within applicable legal deadlines and do not discriminate for exercising protected rights.

Children and policy enquiries

The website is intended for general shopping, not directed to children under 13. We do not knowingly collect personal information from children under 13. A parent or guardian who believes a child supplied information should contact us so we can investigate and take appropriate action, including deletion where required.
