SECTION / 01

Local processing

Photographs, filenames, EXIF details and GPS coordinates do not need to be uploaded to Photo Archive Rescue servers for analysis. Nikon credentials are neither requested nor used.

SECTION / 02

Immutable source

The selected ZIP or source folder is treated as read-only evidence. Organisation and export write new files to a destination chosen by the user.

SECTION / 03

Untrusted ZIP handling

ZIP entries are inspected with controls for traversal, duplicate names, corruption, suspicious compression, excessive depth and expanded-size limits. Unsupported encryption or password protection blocks processing with source-safety guidance.

SECTION / 04

Verification boundaries

Expected presence and size catch missing or truncated destination items. SHA-256 equality confirms copied bytes. It cannot prove Nikon supplied every expected photograph or that an image is artistically correct.
