2. Data Collection and Usage
No Data Collection: We do not collect, store, or share any personal information.
Local Processing: All wallpaper operations, including image selection and visual effects (blur, grain, etc.), are processed entirely on your device.
No Internet Transmission: This app does not upload your photos or any other data to external servers.
3. Device Permissions To provide its core features, the app requires:
SET_WALLPAPER: To update your background based on your schedule or device unlock.
READ_EXTERNAL_STORAGE / MEDIA_IMAGES: To allow you to select images from your gallery to be used as wallpapers.
USE_BIOMETRIC: This is used solely to secure and access your local "Private Albums" if you choose to enable that feature.
4. Image Encryption If you use the "Private Album" feature, your images are encrypted locally using the Android Keystore System (AES-256). These files are stored in the app's internal directory and are not accessible to other apps or services.
