5. Data Retention

We retain your personal information for as long as necessary to provide our services and meet legal, accounting, or reporting requirements. Inquiry records are typically kept for up to 7 years.

7. International Data Transfers

SJ Scientific Limited is incorporated in Hong Kong and our manufacturing operations are based in mainland China. When information must be transferred to handle an inquiry, contract, or support request, we limit access to the relevant recipients and use applicable contractual, organizational, and technical safeguards. Merely continuing to browse the website is not treated as consent to non-essential tracking.

8. Security

We implement reasonable technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet is fully secure.

9. Children's Privacy

Our website and services are intended for business users. We do not knowingly collect personal information from individuals under the age of 18.
