OnlyOnce licence (Mac & Windows)

Unlock the full copy in OnlyOnce, the duplicate photo finder for Mac and Windows.

OnlyOnce finds every duplicate photo and video in your old backups, keeps one checked copy of each, and sorts them by the date they were taken. Your original files are never moved, changed or deleted.

The download and the dry run are free from understandtech.co.uk. This one-off licence unlocks the copy itself.

- Your licence key comes with your purchase

- Works on Mac and Windows

- One-off £9.99, no subscription

- Everything happens on your own computer: your photos are never uploaded
