Privacy notice
Website inquiries and project files
Last reviewed: 29 August 2026
1. Controller and contact
Shenzhen Huayangrun Technology Co., Ltd. / 深圳市桦阳润科技有限公司, operating the HYR FLEX brand, controls the personal information submitted through this website. Privacy and deletion requests can be sent to szbld@vip.163.com with “HYR Privacy” in the subject.
2. Information we collect
The RFQ may collect your name, company, email, phone, country or region, project description, product and timing information, source and campaign fields, and files you choose to upload. Security controls use a daily rotated network digest only in abuse counters set to expire after 24 hours. Expired security counters are removed during later safety checks and by the approved retention process. The digest is not copied into the inquiry record, is not used for marketing analysis, and the website does not store the raw IP address. For planned one-to-one outreach, an approved user may enter a recipient email into the private registry only to create a keyed suppression fingerprint; the raw recipient email is not stored in the outreach-source record or returned by the registry.
3. Why we use it
We use the information to receive and evaluate your request, communicate about engineering and commercial questions, protect the service from abuse, keep a traceable project record, honour requests for no further outreach, and measure whether the website produces genuine business inquiries. We do not sell inquiry data.
4. Project files
Uploaded PDF, PNG, JPG and DXF files enter a private quarantine area with a PENDING status. File metadata may be included in an internal notification. An authorized reviewer must retrieve the quarantined file before recording CLEAN or BLOCKED, and a new review is required before changing that decision. The file is not released to normal sales use unless its current status is CLEAN; BLOCKED files are not released.
5. Retention
- Incomplete orphan uploads: normally deleted within 24 hours.
- Spam and controlled test records: normally deleted within 30 days.
- Unconverted inquiry contact records: retained for up to 24 months, then deleted or anonymised unless a legal need applies.
- Converted project records: transferred to an approved controlled business record; the website inquiry copy is then retained for up to 180 days unless a documented legal hold applies.
- Website-quarantine project files: retained for up to 180 days. A file required for an active customer project may be transferred to a controlled business record, while the website copy still follows its deletion schedule unless a documented legal hold applies.
- Raw analytics events: retained for up to 14 months; non-identifying aggregate reports may be kept longer.
- Keyed outreach-suppression fingerprints: kept only as long as needed to honour a no-contact request and prevent accidental re-contact. They are not used as optional analytics identifiers.
6. Service providers and international processing
The website uses hosting, database, object-storage, security, analytics and notification services needed to operate the inquiry workflow. Information may be processed in locations different from your own. Access is limited to approved people and service providers for the stated purposes.
7. Analytics choice
Essential storage supports the RFQ, security and short-lived attribution needed to understand the request. Optional analytics is not loaded until you select “Allow analytics” in the website preference banner. See the cookie policy for details.
8. Your choices
You may ask for access, correction, restriction or deletion where applicable. We may need enough information to verify the request and may retain limited records where required for legal claims, contracts, tax, fraud prevention or other legal obligations.
9. Security and changes
We use private storage, access controls, file quarantine, event deduplication, test isolation and audit records. No system is risk-free. Material changes to this notice will be published with a new review date.
