🎮 Progressive Web App (PWA)
This app uses a Service Worker to enable offline functionality. The Service Worker caches app files (HTML, CSS, JavaScript, JSON) locally on your device so you can use the app without an internet connection.
Cached Files: index.html, styles.css, app.js, lessons.json, questions.json, manifest.webmanifest, icon.svg
These cached files are stored in your browser's cache storage and can be cleared at any time through your browser settings.
🗑️ Your Data Control
You have complete control over your data:
- Clear Progress: Clear your browser's LocalStorage to reset all progress
- Clear Cache: Clear browser cache to remove cached app files
- Uninstall: Uninstalling the PWA removes all local data
- Browser Settings: Use your browser's privacy settings to manage storage
How to Clear Data in Edge:
- Press Ctrl + Shift + Delete
- Select "Cookies and other site data" and "Cached images and files"
- Click "Clear now"
🌐 No External Connections
This application does not make any network requests after the initial page load. All functionality works completely offline. You can verify this by:
- Opening your browser's Network tab (F12 → Network)
- Using the app and observing zero network activity
- Enabling airplane mode and confirming the app still works
🔄 Changes to This Policy
Since this app operates entirely offline with no data collection, this privacy policy is unlikely to change. Any updates will be reflected in the app's About section and this page.
✅ Summary
In short: Your data stays on your device. We don't collect, transmit, or have access to any of your information. You have complete control and can delete everything at any time through your browser settings.
