Pricing questions, answered honestly
Is there really a free version?
Yes, and it isn't a trial. DiskInsight Free analyzes any drive or folder forever — scanning, all nine visualizers, search, find large files, the live system monitor and the Quick Wins report. There is no timer, no watermark and no "pro sample" of your own disk.
What does DiskInsight Pro add?
Pro unlocks the actions: one-click Quick Wins cleanup, the Dev Cache Cleaner (Xcode, npm, CocoaPods, Gradle…), the duplicate finder, the app uninstaller, snapshots and the screenshot renamer. Same build — paste your key and it's unlocked on that Mac forever.
Is DiskInsight a one-time purchase?
Pro is. One payment of $9.99 (launch), a lifetime license for one Mac, every 1.x update included. There is no recurring fee, no account, no in-app purchases.
How is the launch price different?
The first 100 Pro copies are 50% off ($9.99 instead of the regular $19.99). The live counter on the homepage shows how many are left. Free doesn't change — that's always $0.
If I download free, how do I unlock Pro later?
Buy Pro, get your key by email, paste it into the app — no reinstall, no re-scan. Your existing scans and settings carry straight over.
What if I'm not satisfied?
There's a 15-day money-back guarantee on every Pro purchase. Email us and we'll refund the full $9.99 — no forms, no questions. Your key stops working, and the free analyzer stays free.
Why a guarantee instead of a free trial?
Because the analyzer is free for real, not time-boxed: you can analyze any drive, see every candidate group, cache folder and byte cost — forever. The one part you can't test without unlocking is the click that actually moves files, so we guarantee that: a full refund for 15 days, no questions. The 50% launch price is locked for the first 100 copies either way.
Can I move the license to another Mac?
Yes. The license works on one Mac at a time, and it's attached to an email — contact support and we'll transfer it whenever you upgrade machines.
What happens when 1.1 or 2.0 comes out?
Every 1.x update is free for your lifetime. If a future major version is ever paid, it will be optional — your existing license keeps working forever.
Why is it free but also paid?
The analysis — the hard part — is free for everyone, forever. We make money once, from the people who want cleanup, with no subscription and no telemetry (so no data to sell either). Free tools that "pay for themselves" with ads or analytics are worse for you; our Free tier is funded by Pro, not by your data.
Your Mac is hiding gigabytes. Start free.
