Privacy Policy

Who is responsible

ZHEJIANG SENYO BIOTECH CO., LTD. operates the Senyo website and is responsible for handling your business inquiry. Our company is based in Huzhou, Zhejiang, China.

Information we receive

The inquiry form collects your name, company, email address, country or region, inquiry purpose, any selected ingredient, your project brief and your privacy confirmation. We also receive information you provide in subsequent correspondence.

The form includes source information such as the referring page within this website, landing page, campaign parameters and the inquiry link or ingredient selection that brought you to the form. This helps us understand and respond to the context of your inquiry.

Please provide only information needed for your inquiry. Do not submit confidential formulas, trade secrets, sensitive personal information or information about children.

How we use information

We use this information to receive and route inquiries, review requirements, assess product or project suitability, request clarification, respond and maintain relevant business correspondence. Technical information also supports delivery, security and troubleshooting.

Submitting an inquiry does not create a contract or guarantee a quotation, sample or project acceptance.

Website hosting and browser storage

Cloudflare Pages hosts and delivers this website. Hosting and form services may process technical request information, including IP addresses, browser information, request times and referring addresses, to deliver and protect their services.

Our inquiry flow uses browser session storage to retain source context and record a successful submission during the browsing session. This is separate from website analytics. Browser settings and session restoration can affect how long session information remains available.

For information about Cloudflare's handling of service data, see its Privacy Policy.

Form delivery, email and access

Formspree receives form submissions and stores a delivery copy. An enabled email notification sends the submission to a Google Groups distribution group. The group distributes each email to a Google Workspace business mailbox and a WeCom business mailbox used for inquiry handling. The group also keeps conversation history, which is accessible to group members.

The project lead reviews inquiries. Inquiry correspondence and attachments may therefore be held in Formspree, Google Groups, Google Workspace and the WeCom mailbox. Each of these locations is included in our inquiry retention and deletion process; deleting a message in one location does not establish that other copies have been deleted.

For information about Formspree's processing, see its Privacy Policy.

Website analytics

We use Plausible for aggregate statistics about visits, referral sources, device and browser categories, approximate location and interactions such as ingredient links and inquiry submission outcomes.

Our event configuration excludes contact details and free-text inquiry contents from analytics event properties. Source and campaign information sent with an inquiry is handled separately from these statistics.

Plausible describes its analytics as cookie-free and does not track visitors across websites. See its Data Policy. This does not mean that the website's inquiry flow uses no browser storage or that hosting and delivery services process no technical information.

How long we keep information

Our retention rules apply to inquiry records and the copies we control across the services and mailboxes described above:

• Formspree delivery copies: only long enough to verify delivery and resolve submission issues, normally no more than 30 days.
• Ordinary unconverted inquiries: 12 months after the last substantive business interaction, followed by deletion or irreversible anonymization.
• Test, spam or clearly invalid submissions: no more than 30 days; they may be deleted sooner.
• Completed quotation, sample and project follow-up records: normally 36 months after the last substantive business interaction or the end of the relevant business activity, whichever is later, followed by deletion or irreversible anonymization.
• Contracts, orders, tax and accounting records, and records needed for fulfilment, complaints or disputes: retained according to the applicable business and legal requirements. These are not all subject to the same 36-month limit.

A substantive business interaction concerns requirements, quotations, samples, fulfilment or another meaningful business exchange. Internal forwarding, opening an email or an automated reply does not by itself restart the retention period. Copying a record to another system does not restart it either.

These are our record-management rules, not a claim that every service automatically deletes records on the same schedule. Any necessary retention exception is reviewed for its purpose, scope and next review date.

Processing in different countries

Our company operates in China and uses the service providers described above. Information may be processed in countries other than your own. Formspree's policy describes processing in the United States and other countries where it operates. The location and handling of provider data depend on the relevant service and applicable terms.

Your choices and privacy requests

You can choose not to submit the form. If required contact or project information is missing, we may be unable to respond or assess your request.

You may contact us to request access to, correction of or deletion of personal information associated with your inquiry. Depending on applicable law, you may also have rights to object to or restrict processing, request portability, withdraw consent where processing relies on it, or complain to a competent data protection authority.

Please identify the email address used for the inquiry and, if possible, its approximate date. We may request proportionate information to verify your identity before disclosing or changing records. We will consider the request across relevant records and copies, explain any applicable retention exception and respond within the time required by applicable law.

Contact and notice updates

For privacy questions or requests concerning an inquiry, contact info@senyobiotech.com. This website is intended for business inquiries, not for use by children.
