Privacy Policy

Who We Are & Scope

Who is responsible for your information

Jiangsu Tianjiang Biotechnology Co., Ltd. (“Tianjiang,” “we,” “our,” or “us”) operates tianjiangmodifiedstarch.com. This policy explains how personal information is handled in connection with this website and related business communications.

When this policy applies

This policy covers website visitors and people who contact us about products, technical support, quotations, samples, or business relationships. Separate notices may apply to other activities and will be provided where relevant.

Personal information means information that identifies an individual or can reasonably be linked to an individual. Information about a business contact may therefore be personal information, even when used in a business context.

Information We Collect

Information you provide

Our website contact form requests your name, email address, country, and message. You may also provide additional information when corresponding with us or requesting technical assistance.

Required fields are indicated on the relevant form. If you do not provide the information needed to respond or arrange a requested service, we may be unable to complete that request.

Information collected automatically

Depending on your browser and the services used to deliver the website, technical information may include an IP address, browser and operating system, requested page, referring page, access time, and error information. Optional measurement or advertising services may process additional identifiers and interaction data when deployed. The categories depend on the active services and your choices.

Information from other sources

If you contact us through a business event, partner introduction, or a third-party communication platform, the information involved depends on what you or that source provides. This may include your business contact details and the subject of your inquiry. Please contact us if you would like information about the source of a particular record.

How We Use Your Information

Inquiries & technical support

Information you provide in an inquiry is used to understand your request, communicate with you, and discuss relevant products or application requirements.

Samples & business relationships

Where you request samples or enter into a business relationship, relevant contact and delivery information is used to coordinate that request and related communications.

Website operations & communications

Technical information may be used to deliver pages, investigate errors, protect the website, and understand performance. Where optional analytics, advertising, or marketing tools are used, the purpose and available controls depend on that service. Sending an inquiry is separate from choosing to receive marketing communications.

Automated decisions & profiling

The use of analytics or audience tools may involve grouping visits or interactions for measurement purposes. This policy does not establish that Tianjiang makes decisions with legal or similarly significant effects solely through automated processing. Contact us if you have a question about how a particular business decision involving your information was made.

Legal Bases for Processing

Applicable processing grounds depend on the activity and the law that applies to it. The basis must be assessed for each purpose rather than assumed from a visitor’s use of the website.

Applicable processing grounds

Where a law requires a legal basis, the basis depends on the particular purpose and circumstances. Relevant grounds can include consent for an optional activity; steps you request before entering into a contract with you; performing a contract with you; meeting a legal obligation; or legitimate interests in responding to business inquiries and operating a secure website, subject to the requirements of that law. Information about the ground applicable to a particular interaction can be requested using the contact details below.

Consent & withdrawal

Where processing relies on your consent, you may withdraw it using the relevant preference control or by contacting us. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.

Cookies & Similar Technologies

Cookies are small files stored on your device. Similar technologies may access or store information used for website functionality, preferences, measurement, or advertising. The purposes and providers depend on the tools actually deployed on this website.

Cookie categories

These descriptions explain common categories; they are not a statement that every category is active on this website.

Analytics & advertising

Optional analytics can measure visits and interactions. Optional advertising tools can measure campaign results or support audience-related functions. Their presence depends on the website configuration. Cookie categories describe purposes; they do not identify a provider or establish that every category is deployed. Contact us for information about a particular technology you encounter.

Managing your preferences

If cookie controls are available on this website, you can use them to review or change optional technology choices. You can also review your browser’s cookie settings. Browser settings do not necessarily control every tracking technology, and blocking essential cookies may affect website functions.

Cookie settings are available through the website’s consent control when it is active.

The website preference control records your choices on your device using local storage under tianjiang_cookie_choices_v1. In the supplied consent interface, a saved choice expires after 180 days. This record includes the selected categories, a version number, and save and expiry times. Clearing browser site data can remove the record. A preference interface controls optional tools only when those tools have been connected to it; browser settings and provider controls may offer additional choices.

How We Share Information

Service providers

Depending on the services involved, recipients may include website hosting and infrastructure providers, email and communication providers, and technical support providers. If measurement or advertising services are deployed, the relevant providers may also receive information associated with their functions. The recipient and its role depend on the specific interaction.

Business & logistics partners

When a request involves sample delivery or assistance from a business partner, relevant recipient, delivery, and inquiry details may need to be provided to a courier or the partner involved in fulfilling that request. Avoid including unrelated personal information in delivery instructions or technical messages.

Legal disclosures

Information may need to be disclosed where required by applicable law, a binding legal process, or a competent authority. Any description of additional disclosures should reflect the circumstances in which they actually occur.

Some privacy laws apply special rules to disclosures for targeted advertising or activities defined as a sale or sharing of personal information. The application of those rules depends on the actual tools and data flows. If you have a question or wish to exercise a relevant opt-out right, contact us and identify the activity concerned.

International Data Transfers

Where information is processed

Tianjiang is based in Suqian, Jiangsu, China. International communications may involve the transfer of information across borders.

If you send an inquiry to our team in China, your message and contact details may be accessed there for the purpose of responding. Hosting, email, and other services may involve processing in additional locations, depending on the provider. Contact us for details about the locations relevant to your interaction.

Applicable safeguards

The requirements for an international transfer depend on the countries, organisations, and applicable law involved. This notice does not assert that a particular adequacy decision, certification, or contractual transfer mechanism covers every interaction. You can request information about the arrangements relevant to your personal information using the contact details below.

Data Retention & Security

How long we keep information

The period needed for an inquiry depends on whether follow-up, technical support, a sample request, or a continuing business relationship remains active. Business records may also be subject to tax, accounting, contract, dispute, or other legal requirements. Technical records depend on operational and security needs and provider settings. The supplied cookie-choice record is configured to expire after 180 days. Contact us for the retention period applicable to a particular record or to request deletion where available.

How we protect information

Security arrangements depend on the systems and providers used to handle information. This policy does not imply a specific security certification or guarantee that every system is risk-free. If you need to share confidential material or sensitive information, contact us first to agree an appropriate channel.

No method of internet transmission or electronic storage can eliminate all security risks. Please avoid including unnecessary sensitive personal information in ordinary business messages.

Your Rights & Choices

Your rights depend on your location, the applicable law, the information involved, and the grounds for processing. Relevant rights may include the following:

• Access: request information about processing and a copy of your personal information.
• Correction: request correction of inaccurate or incomplete information.
• Deletion: request deletion where the applicable conditions are met.
• Restriction or objection: request limits on, or object to, certain processing.
• Portability: receive certain information in a usable format where applicable.
• Withdrawal of consent: withdraw consent where it is the basis for processing.

Making a request

Use the contact details in Section 12 and describe the request and your relationship with us. We may need proportionate information to verify your identity before disclosing or changing personal information. Do not send identity documents unless specifically requested through an appropriate channel.

Requests are handled in accordance with applicable requirements. Some rights are subject to conditions or exceptions. You may also have the right to complain to the relevant data protection authority.

Where local law provides additional rights, such as an appeal or an opt-out from certain processing, you may raise those requests using the same contact details. The applicable response period and any permitted extension depend on that law and the nature of the request. If you are in the United Kingdom, information about complaints is available from the Information Commissioner’s Office. In other locations, you may contact your competent data protection authority.

Third-Party Links & Services

External websites

Our website contains links to external services, including map and messaging services. When you follow an external link, that service’s own privacy information applies to its handling of your information.

Embedded tools & content

An embedded map, video, communication widget, or other third-party tool may process technical information when it loads or when you interact with it. An ordinary external link generally takes you to a separate service when you follow it. The controls available for embedded tools depend on how the particular tool has been configured; review that provider’s notice before supplying information directly.

Please review the privacy information of a third-party service before providing information directly to it.

Children’s Privacy

This website presents ingredients and technical information for business audiences. It is not designed as a service for children.

If you believe a child has provided personal information through this website, please contact us with enough information to locate the relevant communication. We will assess the report and take appropriate action under applicable law.

This policy may be updated to reflect changes in website services, information handling, or applicable requirements. This version is dated October 12, 2026. Future revisions will show their own update date. Additional notice will be provided where required.
