🛡️ PicBan - Protect Your Privacy Before You Upload

Ever accidentally uploaded a photo you immediately regretted? PicBan is your intelligent safety net that analyzes images BEFORE they leave your device, helping you avoid embarrassing or privacy-compromising uploads.

What PicBan Does

PicBan automatically scans photos when you try to upload them to any website - social media, email, messaging apps, forums, or anywhere else. If it detects potentially sensitive content, it shows you a warning so you can make an informed decision before sharing.

🔒 100% Private - No Cloud, No Tracking

Unlike other content moderation tools, PicBan works ENTIRELY on your device. Your photos are NEVER sent to any server. All analysis happens locally using machine learning models that run in your browser. No data collection, no tracking, no cloud processing - just pure local protection.

✨ Key Features

• NSFW/Nudity Detection - Multi-method AI detection combining three different approaches for maximum accuracy. Catches explicit content that could be embarrassing or inappropriate to share publicly.

• Child Face Detection - Automatically warns when photos contain children's faces, helping parents and caregivers protect kids' privacy online. Uses advanced facial landmark analysis to identify young faces.

• Swimsuit/Revealing Photo Alerts - Get warned about beach photos, swimwear, or revealing clothing before uploading. Smart context detection allows normal beach vacation photos while flagging potentially inappropriate content.

• Blood/Gore Detection - Five-layer detection system identifies graphic content including wounds, blood, and violence. Useful for preventing accidental sharing of sensitive medical or accident photos.

• Test Any Image - Use the built-in Test Image feature to check any photo against all detection rules before uploading. See exactly what PicBan detects and why.

• Site Whitelist - Quickly whitelist trusted sites where you don't need scanning. One-click toggle right from the popup - no settings page needed.

• Customizable Sensitivity - Adjust detection thresholds to match your comfort level. More sensitive catches more, less sensitive reduces false positives.

• Import/Export Settings - Backup your configuration and restore it on another browser or after reinstalling.

🔧 How It Works

When you select, drag-drop, or paste an image on any website, PicBan intercepts it and runs it through multiple AI models:

NSFWJS for explicit content classification
MobileNet for image context analysis
COCO-SSD for person detection
MediaPipe Face Detector for facial analysis
Analysis takes less than a second. If anything concerning is detected, you'll see a clear warning with details about what was found. You always have the final choice - proceed with upload or cancel.

⚙️ Smart Detection

PicBan isn't just a simple filter. It uses context-aware detection that understands the difference between:

A beach vacation photo (allowed) vs. inappropriate nudity (blocked)
A normal portrait (allowed) vs. a child in a concerning context (warned)
Red clothing (allowed) vs. actual blood/wounds (blocked)

📊 What Gets Detected

• Explicit nudity and pornographic content
• Partial nudity and revealing poses
• Children's faces (for privacy protection)
• Swimwear and revealing clothing (optional)
• Blood, wounds, and graphic content
• Violence-related imagery
