Technabit
My Photo Copy makes one safe copy of your photos and videos on a drive you own. Plug in a USB-C stick, an SSD or an SD card reader — or pick any folder in Files. Choose what to copy. The app writes your originals to the drive, then reads every file back off the drive to check that it arrived.
Nothing is uploaded. No account, no server, no subscription standing between you and your photos. What lands on the drive is ordinary folders and ordinary files, sorted by the date each photo was taken, readable on any computer without this app.
