Privacy Policy

Placeholder notice. This page is a minimum-information placeholder. The final, jurisdiction-specific policy is pending legal review.

1. Who we are

Chengxin Computer ("we", "our", "us") is a custom application development studio operating since 2021. You can reach us at chengxin.site@gmail.com.

2. What data we collect

This marketing site collects very little personal data:

Contact submissions. If you email us, we receive your email address and the contents of your message.
Local preferences. Your selected interface language is stored in your browser's localStorage under the key ng-lang. This stays on your device and is never transmitted to us.
Server logs. Our hosting provider (Firebase Hosting / Google Cloud) keeps standard request logs (IP address, user agent, requested URL, timestamp) for security and operational purposes.

3. Why we collect it

We use the data above only to respond to enquiries you initiate and to operate this website securely. We do not run advertising, behavioural tracking, or sell your data to anyone.

4. Who we share data with

We share data only with infrastructure providers required to deliver this site — currently Firebase Hosting (Google LLC) — and only as necessary for hosting and security. We do not transfer your data to third parties for marketing.

5. Your rights

Depending on where you live, you may have the right to access, correct, or delete personal data we hold about you, and to object to certain processing. To exercise these rights, email chengxin.site@gmail.com and we will respond within a reasonable timeframe.

6. Children

This site is not directed at children under 13. We do not knowingly collect personal data from children.

7. Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top reflects the most recent change. Material changes will be flagged on this page.
