Privacy Policy
Last updated: 2026-09-11
1. Who We Are
Shenzhen Sainsun Packaging Co., Ltd. ("Sainsun", "we", "our", "us") operates the website sainsunpack.com (the "Site"). We are a custom flexible-packaging manufacturer registered in Shenzhen, Guangdong, China.
For any privacy questions, contact us at Leolian@sainsunpack.com.
2. What We Collect
We collect only the information you voluntarily provide when you:
- Submit the inquiry or contact form (name, email, company, country, message)
- Email or WhatsApp us directly
- Place an order through our Alibaba Verified Store
We do not use tracking pixels, third-party advertising cookies, or behavioral profiling on this Site.
3. How We Use Your Data
- Respond to your inquiry with a quote, sample plan, or technical answer
- Route your request to the correct specialist (sales, R&D, or QC)
- Fulfill orders placed through Alibaba's trade assurance system
- Keep records for tax, customs, and trade-compliance purposes (as required by Chinese and international law)
We never sell your data. We do not share your data with third parties for marketing purposes.
4. Data Retention
Inquiry data is retained for up to 24 months after our last contact with you, after which it is deleted or anonymised. Order records are retained for 7 years to meet Chinese accounting and customs requirements.
5. Your Rights
You have the right to:
- Request access to the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data (subject to legal retention requirements)
- Opt out of future communications at any time
To exercise any of these rights, email Leolian@sainsunpack.com.
6. Cookies
This Site does not set any non-essential cookies. Our hosting provider (Cloudflare) may log standard server-side request metadata (IP address, user agent, timestamp) for security and abuse-prevention purposes, retained for up to 30 days.
7. International Transfers
Because we export to North America, Europe, and the Middle East, your inquiry data may be processed by our team in China. By submitting an inquiry you consent to this transfer. We do not transfer data to any country outside of China for marketing or analytics purposes.
8. Third-Party Links
Our Site links to our Alibaba Verified Store and WhatsApp for your convenience. Those platforms have their own privacy policies — we are not responsible for how they handle your data once you leave our Site.
