Privacy Policy

Last updated: April 2026

Overview

Zango Tech ("we", "us") operates the ACL Pack website and SDK. This policy describes how we collect, use, and protect your information.

Information We Collect

Contact Forms

When you contact us, we collect: company name, contact name, email address, and project requirements. This information is used solely to respond to your inquiry.

SDK License

The licensed SDK includes a license.dat file carrying a licenseId that is recorded against your Taobao purchase (buyer ID + order number) in our delivery ledger for traceability. The file is read-only — ACL Pack never writes to disk. No user data, device identifiers, or usage telemetry is collected by the SDK at runtime.

Website Analytics

We may use privacy-respecting analytics to understand website traffic. No personal data is shared with third parties for advertising purposes.

Data Usage

• Contact form submissions are used only to respond to inquiries
• License information is used only for license validation
• We do not sell or share personal data with third parties

Data Retention

Contact form data is retained for the duration of the business relationship. You may request deletion at any time by emailing zangotech@163.com.
