1. Scope and identity of the operator
This website, www.dgpinyi.com, is operated by Dongguan Pinyi Electromechanical Technology Co., Ltd. — referred to below as “we” or “us”. The present policy governs all content and functionality available on that domain, including the gear selection tool, the AI assistant embedded in the site, and every channel through which enquiries may be submitted.
2. How long records are held
| Record type | Kept for |
|---|---|
| Enquiry and business correspondence records | 3 years |
| Assistant conversation records | 12 months |
After the applicable period lapses, the affected data is deleted or anonymised so that individuals can no longer be identified from it.
3. Categories of data collected and the purpose of collection
Information reaching our systems falls into three groups.
Information supplied by you. Submitting the enquiry form, operating the gear selection tool, sending email, or conversing with the on-site assistant all result in our receiving your name, email address, company name and message, together with whatever technical parameters and drawings accompany them. Such data enables us to answer you, prepare quotations, and conduct technical discussions.
Assistant conversation logs. Messages you direct to the on-site AI assistant are retained on our servers. Keeping the transcript allows us to respond to you and to improve the service over time.
Technical connection records. Our logs capture a session identifier, the IP address you connect from, and the moment of access. These records sustain service availability, underpin access control and rate limiting, and assist in preventing misuse.
No third-party advertising or behavioural tracking scripts are present on this website.
4. Purposes of processing
- Responding to enquiries, producing quotations, and developing technical solutions jointly with you.
- Supporting manufacturing, shipping and after-sales handling of your orders.
- Maintaining the security and stability of the website and the assistant, rate limiting and abuse prevention included.
5. Disclosure practices
Your information is neither sold nor rented by us. Where a quotation or a production step requires it, the partner workshop performing that step is given access solely to the technical data that step demands, and confidentiality obligations bind that workshop. Any further disclosure occurs only where the law compels it or where a legally empowered authority issues a demand.
6. Cookies and local storage
Only strictly functional items are stored by the site — a language or theme preference, for example, alongside a session identifier used by the assistant. Third-party advertising cookies are not employed.
7. Location of processing
Processing may occur within China, since our servers are located there, Hong Kong included.
8. Your rights
At any time you may contact us using the details listed below in order to inspect, correct, or request deletion of the personal information we hold about you.
9. Revisions and contact information
This policy may be updated from time to time; each revision becomes effective on the date it is published.
