JavaScript Starter Privacy Policy

Updated: August 29, 2026
Effective: August 29, 2026

JavaScript Starter is provided by Dozen Network Technology Co., Ltd. This policy follows the same series policy used by C++ Starter and Python Starter.

1. Local data and execution

Project names and identifiers, main.js source code, input, output, course progress, purchase entitlement status, and settings remain in the app sandbox on the current device. Apple JavaScriptCore executes code locally. We do not upload source code or read keyboard input from other apps.

2. Online services and logs

Purchases, restoration, and App Store version checks may contact Apple services. If update-policy functionality is enabled, our service may receive IP address, request time, path, User-Agent, response status, duration, and related operational logs. We do not use these data for advertising, cross-app tracking, or sale to data brokers.

3. Support, retention, and rights

If you email support, we use the address, message, and attachments to respond and troubleshoot. You can delete projects in the app or uninstall it to remove local data. Operational logs are retained only as needed, then deleted or anonymized. You may request access, correction, deletion, or restriction under applicable law.

4. Children and contact

Children under 14 should use the app with a parent or guardian’s consent and guidance. For privacy questions or rights requests, contact ministep@dozen.network.
