Privacy Policy

Welcome to Interactive: Live Wallpaper 4D (the "App"), developed and published by Cantora Design ("we", "us", or "our"). We are committed to protecting your privacy and ensuring transparency regarding how your data is collected, used, and shared when you use our interactive 4D live wallpaper and theme customization application.

By downloading, accessing, or using Interactive: Live Wallpaper 4D, you consent to the practices described in this Privacy Policy. If you do not agree with this policy, please do not use the App.

1. Information We Collect

We do not require you to register an account with your name, email address, or phone number to use the App. We collect limited information to provide, maintain, and improve your experience:

• Theme Customizations & Local Preferences: selected 4D themes, favorite wallpapers, lighting modes, effect layer toggles, custom background/sprite textures imported from your gallery, quality settings, and language preferences are stored locally on your device so your live wallpaper configuration persists across sessions.
• User-Selected Photos & Sprites: if you choose to customize a 4D wallpaper using an image or PNG sprite from your device gallery, the selected image is processed and stored strictly locally on your device. We never upload your personal photos to any external server.
• Sensor Data (Parallax / Tilt): for 4D themes that react to device movement, accelerometer/tilt sensor readings are processed locally in real time to animate 4D depth and physics effects and are never transmitted off your device.
• Anonymous & Advertising Identifiers: app instance identifiers and Google Advertising ID (GAID) collected in compliance with Google Play Developer policies for advertising, mediation, and attribution (subject to your consent settings).
• Device & Technical Information: device model, manufacturer, operating system version, app version, language, screen resolution, and general interaction events within the App.
• Crash & Performance Logs: diagnostic logs, crash traces, and OpenGL rendering performance metrics collected via Firebase Crashlytics to fix bugs and maintain stability.

2. Device Permissions Used

The App requests Android permissions strictly necessary to deliver core 4D live wallpaper and customization functionality:

• Set / Bind Live Wallpaper (android.permission.BIND_WALLPAPER): required by the Android system so you can apply interactive 4D scenes as your home screen or lock screen live wallpaper.
• Internet & Network State (INTERNET, ACCESS_NETWORK_STATE): required to download 4D cloud theme packs, load remote configuration, analytics, and advertisements.
• Advertising ID (com.google.android.gms.permission.AD_ID): required on Android 13+ devices to access the Google Advertising ID for ad mediation and attribution purposes.
• System Photo Picker: used only when you explicitly choose to import a custom background photo or sprite image from your gallery for DIY wallpaper customization.
