Privacy Keeper detects and anonymizes faces and license plates in equirectangular panoramic images — fast, offline, and entirely on your own hardware.
Everything runs locally on your machine. No cloud services, no uploads, no third parties.
AI-based face and license plate detection trained for maximum accuracy and performance.
NVIDIA CUDA acceleration for maximum performance, with automatic CPU fallback if no compatible GPU is available — no configuration required.
Your images never leave your computer. Original files are never modified — all processed images are saved separately.
Review every detection at full resolution. Add missed faces or plates, remove false positives, and fine-tune results before export.
Create permanent masks to hide static areas such as your recording vehicle's roof. Store different masks for different vehicles and customize mask colors.
Add custom watermarks such as © YourCompany. Configure font, size, rows, columns, rotation, opacity, and color.
