LZPIC Privacy Policy
Effective Date: September 22, 2026
Operator: Huanzhi Tech
LZPIC is an offline mobile photo editing and darkroom atelier application crafted by Huanzhi Tech. Offline by design is our core brand commitment: photo processing, color curves, LUT filters, and AI portrait segmentation occur strictly on your device hardware without uploading your pictures.
1. Zero Cloud Uploads & Local Pipeline
LZPIC operates zero remote photo editing servers. Your images never leave your device.
- GPU Shader Pipeline: Cropping, light curves, LUT filters, and export rendering execute 100% on your device’s native GPU shader pipeline.
- Local Studio Library: Draft transaction stacks are serialized locally in application sandboxes.
- On-Device Segmentation: AI portrait segmentation utilizes embedded on-device models (such as MediaPipe), running directly on local silicon with zero cloud dependencies.
2. Permissions
| Permission | Usage Timing | Purpose | Network Upload |
|---|---|---|---|
| Photo Library (Read) | When you select photos to edit | Read user-chosen images into memory | No (Local only) |
| Photo Library (Write) | When you tap “Export” | Save finished high-resolution works into your camera roll | No (Local only) |
3. Data Purge & Account Freedom
LZPIC requires no online account. Deleting items inside the Library removes draft metadata. Clearing application data in device settings or uninstalling the app permanently deletes local app caches. Exported photos in your camera roll remain under your direct manual management.
