Privacy Policy

NegaScan processes all images and video streams strictly on your client device. No image data is collected or uploaded.

1. Zero Cloud Data Collection

NegaScan is engineered strictly as a client-side web application. When you load photos, negative camera digitizations, or video feeds into the tool, they are read directly into browser memory and rendered via your local GPU (WebGL).

No image data, pixel buffers, file paths, or EXIF metadata are ever uploaded, transferred, or archived on remote servers or cloud storage.

2. Local Device Permissions

If you utilize real-time camera scanning, browser camera access is requested solely to stream video frames into the WebGL texture pipeline in your local browser window. Camera permissions can be revoked at any time via your browser settings.

3. Cookies and Analytics

NegaScan does not use third-party advertising cookies, cross-site trackers, or commercial marketing SDKs. We do not sell, rent, or trade any personal information.
