Information and purposes

Our inquiry form requires your name, email address and message so we can understand and reply to your request. You may also provide your company, phone or WhatsApp number, product, purity or grade, quantity, packaging and destination. We record the selected website language. Optional fields can be left blank. Without the required contact and request details, we may be unable to respond. Please do not submit payment details, identity documents or sensitive personal information.

We use inquiry information to respond, discuss specifications, prepare quotations, maintain relevant correspondence and protect against misuse. Submitting an inquiry does not subscribe you to promotional messages. We seek separate permission for marketing where required.

Shopify, our website platform, also processes technical information such as IP address, device and browser details, page interactions and cookie identifiers to operate, secure and measure the service. See our Cookie notice and Shopify's linked notices below.

Grounds for processing and recipients

We rely on your consent where required, steps you request before a contract or performance of a contract where applicable, and legal obligations. Where local law permits, necessary site security and business correspondence may rely on legitimate interests. We do not treat merely browsing the website as consent to every use of information.

Relevant information is available to authorized staff and to hosting, email and technical service providers as needed to handle your inquiry and operate the website. Information may be disclosed when required by law or to establish or defend legal claims. Any further disclosure needed for a transaction will be explained as appropriate.

Shopify and international processing

Your inquiry is handled by our company in China. Shopify and its service providers may process website and inquiry information outside your country, including in Canada and the United States. This involves collection, transmission, hosting and access for the purposes described above. Country protections can differ. Where applicable, transfers require the safeguards and separate consent required by law; publishing this notice does not replace those requirements.

Shopify may also process visitor information for its own platform services and enabled enhanced features under the Shopify Consumer Privacy Policy. See Shopify's privacy information and its privacy portal for Shopify's processing, international transfers and choices. Contact us at the address above about our handling of your data.

Retention and protection

We keep inquiry information only as long as needed to respond, follow up on an active business discussion, meet applicable recordkeeping duties or resolve disputes. The period depends on whether an inquiry progresses into a business relationship and on applicable legal requirements. You can request deletion or details about retention by email. We use reasonable safeguards, but no online service can guarantee absolute security.

Your choices and rights

Contact sales@hanhogas.com to request access, a copy, correction, deletion, restriction, objection, withdrawal of consent or other rights available under applicable law. Specify your request and the email used for the inquiry; we may reasonably verify your identity. We respond within the applicable legal time limit, explain any lawful refusal and do not retaliate for exercising rights. Withdrawal does not affect lawful processing already carried out. If you disagree with our response, reply to request a review or contact the competent authority.

United States residents may have state-specific rights, including rights concerning targeted advertising, sale or sharing, portability and appeals, where the relevant law applies. Thai residents may have rights under the PDPA; Vietnamese residents may have rights under applicable personal data protection law. Rights, exceptions and deadlines depend on the applicable law. Contact us to exercise them or raise a complaint. Shopify's privacy portal provides separate controls for Shopify's own processing.

The site is intended for adult business contacts. We do not knowingly seek children's information. Please notify us if a child has provided personal information.

Updates

We will publish revisions on this page, update the date, and provide additional notice or obtain consent when required for material changes.
