It scans everything, you handpick what you delete.

System Data Files

Caches, logs, and temporary files that pile up invisibly. After Effects alone can leave 80GB of render cache you never knew existed.

That 4K export from 2019 sitting in your Downloads folder. Old Xcode simulators. Virtual machine files you stopped using. All surfaced, sorted by size.

Safe Tag & Apple Intelligence Summary

Safe. Temporary files that regenerate automatically.
What's this? A temporary cache created by Google's Chrome browser, intended to store browsing history and cache data for faster access during future sessions. It is generally safe to remove for disk cleanup, as it doesn't contain user-sensitive data and can be recreated if needed.

Frequently asked questions

Everything you need to know.

No. Never. $9.99, once, forever. No account required either.

Yes. You pay once and own DataSweeper forever. All future updates are completely free — no upgrade fees, no "pro" tiers, no expiring licenses.

DataSweeper supports macOS Sequoia and macOS Tahoe. It runs natively on Apple Silicon (M1, M2, M3, M4) and Intel Macs. Mac only — no iOS or iPadOS.

No. Everything happens locally on your Mac. Zero network connections, zero telemetry, zero analytics. Your file names and usage patterns never leave your machine.

No. It only scans when you open it and start a scan. No background agent, no menu bar daemon, no scheduled processes running without your knowledge.

Four categories: System Data (caches, logs, temporary files), Duplicate Files (exact matches via SHA-256), Large Files (forgotten exports, old simulators, VM files), and Junk Files (old installers plus leftover files from apps you've already uninstalled).

CleanMyMac is $40/year and does 25+ things. DataSweeper is $9.99 once and does the one thing most people actually need: finding what's eating your disk and cleaning it up safely. No subscription, no telemetry, Trash-first always. Full comparison →

I built DataSweeper because I wanted to clean my Mac quickly and cheaply. Most apps do too much or are too expensive. Paying a monthly fee for something I use a couple of times a year seemed like overkill. So I built the app I wished existed — simple, cleans system data and more, with a nice user experience. I hope you'll like it too. I'm also a solo builder, very keen on making it better, so if you need anything, shoot me a message!
