Privacy Policy

Overview

This Privacy Policy describes how Java Challenge Trainer (the "App"), developed by Japps.ai, handles information when you use it.

Information We Collect / Do Not Collect

The App is a single web page that runs entirely in your browser. We do not collect any information about you:

• No account, name, email address or sign-in of any kind.
• No analytics, advertising or tracking cookies.
• Your answers and the input you type into the stepper are checked on your own device and are never sent to us.

Local Storage / Backend Storage

The App saves two things in your browser’s local storage: which questions you have solved and which lesson you last opened. This lets you pick up where you left off. The data never leaves your device, and there is no backend server or database. You can erase it at any time with the “Reset progress” link at the bottom of the App, or by clearing your browser’s site data.

Third-Party Services

The App is hosted on GitHub Pages and loads its typefaces from Google Fonts. As with any website, these providers receive standard technical information, such as your IP address and browser type, when your browser requests the page and the font files. Their own privacy policies govern that information. The App uses no other third-party services.

Children's Privacy

Java Challenge Trainer is not directed at children under the age of 13, and we do not knowingly collect any information from minors.

Changes to This Policy

If this Privacy Policy is updated, the new version will be posted at this URL with a revised effective date. Continued use after any changes constitutes acceptance of the updated policy.
