Privacy Policy

Effective Date: May 14, 2026

This Privacy Policy applies to eSIM QR Helper developed and published by PureRainCube (Guangzhou Pure Rain Cube Technology Co., Ltd.).

We strongly believe in your right to privacy. Our applications are designed with a strict offline-first and local-processing approach.

1. No Data Collection and No External Servers

We want to be completely transparent about how your data is handled:

No External Servers: We do not provide, maintain, or connect our applications to any external servers for data collection purposes.
No Data Uploads: We absolutely do not upload, transmit, or store any of your personal data, files, usage statistics, or analytics to our servers or any third-party servers.
Strictly Local Processing: All data processing, analysis, and storage occur strictly and exclusively locally on your device. Your data never leaves your phone.

2. Device Permissions

Our applications may request certain device permissions (such as access to the camera or local storage) to function properly. These permissions are used solely to provide core functionality within the app itself. Because we do not have servers, any data accessed via these permissions remains securely on your device.

3. Third-Party Services

Because our applications operate entirely locally without external server communication, we do not integrate third-party analytics or advertising tracking SDKs that collect or share your personal data.

4. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective Date".
