DeDuck Cloud optional

The one thing worth a subscription: connect Immich, Google Photos and Lightroom, and de-duplicate across your cloud and local drives. Real ongoing service, so it's the only recurring plan.

$29/yr  or $4/mo

Prices shown are launch anchors in USD. Local features never require an internet connection or an account.

Why one-time

Your files are yours forever. So is DeDuck.

A tool that tidies files you already own shouldn't rent itself back to you every month. Here's what "pay once" actually saves you versus the subscription cleaners.

Questions

The fine print, in plain words.

Is it really a one-time payment?
Yes. Pro and Studio are one-time purchases for the app's local features — buy the version, own it forever, keep using it offline with no recurring charge. Each purchase includes a window of free updates (1 year for Pro, 2 for Studio); after that you can renew for continued updates at a discount, or simply keep the version you have. The only optional subscription is DeDuck Cloud, because cloud connectors have real ongoing costs.
What can I do without paying?
Everything that helps you understand your clutter: unlimited scanning, the dashboard, exact-duplicate detection, and the shareable Clutter Report. Paying unlocks the ability to act — cleanup, near-duplicate photo matching, and the Master Library.
Does DeDuck need an internet connection?
No. Scanning, detection and cleanup all run entirely on your machine — your file names and contents never leave the device. The app only reaches the internet to activate your license the first time and to quietly re-check it every couple of weeks, with an offline grace period so a dropped connection never locks you out.
How many devices does one license cover?
Pro activates on 2 of your own Macs or PCs; Studio & Family covers 5. You can deactivate a device and move the license to a new one anytime from Help → Unlock Pro.
What if it deletes something I wanted?
DeDuck is read-only by default and previews every cleanup before acting. Duplicates go to the Trash (reversible) unless you choose otherwise, every file is re-hashed right before it's touched, and a duplicate group is never left without a copy. Plus a 30-day money-back guarantee on every purchase.
macOS and Windows both?
Yes — the same license works across macOS and Windows within your device limit. Download the build for whichever machine you're on.
