This policy explains how 北京天瑞森科技发展有限公司 (Teraysun) handles personal information through hongsenbike.com, its enquiry forms, and its sourcing assistant. Privacy questions and requests may be sent to info@hongsenbike.com.
Information we collect
When you send an enquiry, we collect the details you provide. These can include your company, contact name, work email, phone number, product interest, model, quantity, message, delivery country or destination, procurement notes, and the page where you submitted the request. We also record the submission time, source channel, enquiry reference, and your enquiry consent selection where those fields apply.
When you use the sourcing assistant, we process your messages, selected products, basket quantities, product options, and session information needed to keep the conversation and basket together. The website and its security services also process technical information such as IP address, browser information, and security signals to operate the service, limit abuse, and investigate failures.
How we use information
We use enquiry information to understand your sourcing request, prepare or review an RFQ, reply to you, manage follow-up, and keep a business record of the enquiry. We use technical information to operate and protect the website, forms, email workflow, and sourcing service.
Where applicable law requires a legal basis, enquiry handling supports steps you ask us to take before a possible supply arrangement. Service security and necessary business records support our legitimate operational interests. Google Analytics is used only after you give analytics consent.
Sourcing assistant
The sourcing assistant sends your message and relevant catalogue context to an AI service provider to generate a response. Teraysun staff review submitted RFQs and make commercial decisions. Do not enter payment card details, identity documents, passwords, medical information, or other sensitive personal information in the assistant or enquiry forms.
Google Analytics and your choice
If you accept analytics, our website component manually sends one page_view on an approved public page. It sends the website origin and pathname without the query string or page fragment, an approved referrer origin when available, and a fixed page title. The component does not send enquiry submissions, chat messages, names, email addresses, phone numbers, product requests, quantities, internal submission identifiers, or RFQ references to Google Analytics.
Google Analytics can create automatic session events, such as session_start and first_visit, after its tag loads. Enhanced measurement is currently off. Google can also process or derive session and event metadata, its cookie or client identifier, browser and device information, approximate location from network information, and other technical request data. Cleaning the page address and referrer reduces the information sent from the page. It does not make analytics data fully anonymous.
The current Analytics account settings allow Google to use Analytics data to improve Google products and services, contribute to aggregated modelling and business insights, provide technical support, and give business recommendations about the account. These account-level choices are separate from the website setting that disables advertising signals for this measurement.
Use the Analytics settings button on the website to accept analytics, reject it, or withdraw a saved acceptance. A saved rejection or withdrawal stops future analytics loading in that browser until you change or clear the saved choice. It does not erase information collected before withdrawal. If the panel says that the browser could not save your choice, analytics stays off on the current page, but that unsaved choice may not continue on another page or a later visit.
Cookies and browser storage
The website controls analytics from the choice saved in local browser storage. The saved choice remains until you change it or clear that storage. After analytics is accepted, Google Analytics can set the _ga cookie and related property cookies. Google’s default _ga cookie lifetime is up to two years, while browser rules or your settings can shorten it.
The sourcing integration can use session storage for temporary workflow state. Security services can also use cookies or tokens needed to check traffic and protect the service.
Who receives information
Access is limited to Teraysun personnel who handle enquiries or operate the service, plus service providers that support website hosting, business email, network security, AI processing, and analytics. Google receives analytics data only after analytics consent. These recipients use information for the service they provide to us or as described in their own privacy terms.
Where information is processed
Teraysun processes submitted enquiry information in China. Service providers can process information in other countries, including countries outside the place where you live. The destination depends on the service route used for hosting, email, security, AI processing, or analytics. You may contact us for information about a particular transfer connected with your request.
How long we keep information
We retain enquiries and RFQs as business records. We assess deletion requests against the need to handle the request and applicable legal, tax, record-keeping, and dispute requirements. We have not adopted a fixed automatic deletion period for these business records. Technical security records are kept for the period needed to operate, protect, and investigate the service.
The current Google Analytics property retains event-level data for two months and user-level data for fourteen months. User retention resets on new activity. These settings apply to the corresponding non-aggregated data. They do not set one deletion date for standard aggregated reports and do not control the lifetime of analytics cookies.
Your requests and choices
Depending on the law that applies to you, you may request access, correction, deletion, restriction, portability, or object to certain processing. Use the website’s Analytics settings button to reject analytics or replace a saved acceptance with a saved rejection. You may also have the right to complain to the data protection authority that applies where you live.
Send requests to info@hongsenbike.com with enough information to identify the relevant enquiry. We may ask for reasonable proof of identity before acting. A deletion request can be limited where applicable duties require us to keep a record.
Security and changes
We use access controls, transport security, request limits, and service checks to protect website and enquiry information. No internet service can guarantee absolute security.
We will update this policy when our data practices or service providers materially change. The date at the top identifies the current version.
