1. Overview
Artos Studio develops and publishes 4D Parallax Wallpaper 3D & 4K. We respect your privacy and designed the application to operate without requiring account creation, logins, or access to contacts, photos, camera, or microphone.
2. Gyroscope & Accelerometer Sensor Data (100% On-Device)
To create the interactive 4D depth effect when you tilt your smartphone, the app reads motion data from your device's hardware gyroscope and accelerometer sensors.
- Real-Time Local Processing Only: All tilt vectors and orientation angles are computed 100% locally in real time on your device solely to render live depth movements.
- Zero Storage or Transmission: Sensor readings are never written to disk, logged, profiled, or transmitted to Artos Studio servers or any third party.
- Automatic Sleep Pause: Sensor listeners automatically unregister when your screen turns off or while using other apps.
3. Local Wallpaper Caching & Network Requests
- Catalog Fetching & Local Cache: When browsing wallpaper categories, thumbnail previews and downloaded multi-layer wallpaper packs are fetched over HTTPS and cached locally in your device's private app storage so your live wallpaper renders offline smoothly.
- App Settings: Preferences such as parallax sensitivity and unlocked pack entitlements are stored locally via Android DataPrefs / SharedPreferences.
4. Analytics, Advertising & In-App Purchases
- Firebase Analytics & Telemetry: Collects aggregated, non-personally-identifiable telemetry (such as wallpaper category popularity, preview/apply events, and crash diagnostics) to improve wallpaper performance across Android devices.
- Google AdMob (
AD_ID): Free users may view banner, native, interstitial, or optional rewarded ads to unlock PRO wallpapers for free. AdMob processes device Advertising IDs subject to your Google Play & regional consent settings. - Google Play Billing: Pro subscriptions and One-Time Lifetime Unlocks are processed exclusively by Google Play. We receive only anonymous purchase confirmation tokens, never payment card numbers.
5. User Data Deletion Instructions
