DeDuck 3-2-1 Protection & Cloud Reconciliation included in Pro

More than finding duplicates. Complete local and offsite protection.

DeDuck 3-2-1 Protection helps you build a resilient backup strategy across libraries, external volumes, and client-side AES-256 encrypted cloud destinations. Read-only Google Drive reconciliation audits local folders against the cloud, bypassing macOS File Provider placeholder limitations.

No cloud subscription required. Your data stays yours.

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 DeDuck free?
Yes. Free is a permanent product tier — not a trial, not a beta, not a time-limited offer. Download DeDuck, run it, and use all the Free features with no license key, no account, and no expiry. Free gives you unlimited scanning, the dashboard, exact-duplicate detection, and the shareable Clutter Report.
What is Pro?
Pro is a one-time purchase ($49) that adds the ability to act on what you find: file and duplicate cleanup (zero permanent deletion), compare & reconcile two folders with persistent Undo, near-duplicate and look-alike photo matching, master library building with multi-folder batch actions and disk sync, 3-2-1 symmetrical backup protection with AES-256 client-side encryption, read-only Google Drive reconciliation, and scheduled rescans. Buy it once, own it forever — it runs fully offline with no recurring charge. Covers 2 Macs or PCs.
What is Studio?
Studio is a one-time purchase ($99) that includes everything in Pro, plus up to 5 devices, priority perceptual matching for very large photo libraries, bulk NAS and external-drive workflows, priority support, and 2 years of updates included. Ideal for photographers, creators, and households with multiple machines.
Is there a launch discount on Pro?
The first 50 Pro customers receive a special launch discount. The discount is applied automatically at checkout. No code or coupon is required.
Can I request Pro for free?
Yes — use the Request Pro Free form or email hello@deduck.app. Tell us briefly why you'd like to use DeDuck Pro. We review requests individually and will follow up; approval is not automatic.
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. No cloud subscription required. Your data stays yours.
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 Free tier requires no internet at all. Paid plans activate online the first time and include a 14-day offline grace period with quiet background verification, so travel or network drops never interrupt your work.
How many devices does one license cover?
Pro activates on 2 of your own Macs or PCs; Studio covers 5. You can manage and deactivate devices anytime directly in the app under Settings → License, Devices & Upgrades with 1-click self-serve deactivation to immediately free up a seat.
What if it deletes something I wanted?
DeDuck never permanently deletes personal files. Cleanup files are moved strictly to native OS Trash on the source volume (.Trashes on external drives) or to Quarantine. Pre-flight volume validation runs before any action, every file is verified, 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.
