Inside the app
A closer look.






About this app
Made for a clear purpose.
Photocairn is a local file-copy and verification desk for user-selected images, movies, and audio, with user-selected destination folders and source-to-destination SHA-256 checks.
WHAT IT DOES - Choose one or more media files from Files - Choose a destination folder explicitly - Copy with collision-safe destination names - Run an independent SHA-256 comparison and show per-file exceptions
PRIVATE BY DEFAULT No account, advertising, tracking, analytics SDK, or subscription. Workspace data stays in the app container. Imports, scans, device access, and network actions happen only when you request them.
ONE PURCHASE The complete core tool, local workspace, records, analysis, export, and offline reference are included in the paid download.
IMPORTANT BOUNDARY A backup is not complete until the independent verification pass succeeds and the destination is retained safely.
