Clean with a safety net.
Nothing is removed until you've seen it and chosen how it goes. Every file is classified by risk, and only the safest tier is selected by default.
- Step 01
Analyze
Scan caches, logs, Xcode DerivedData, simulators, browser data and temporary files. Every result is sorted by safety tier.
- Step 02
Preview
Expand any category to see individual files and their sizes. You decide exactly what goes — nothing is pre-checked beyond Tier 1.
- Step 03
Clean
Choose how files leave: quarantine with a seven-day undo, the macOS Trash, or a permanent delete.

06 / FAQ
Good questions.
Still unsure about something? Write to contact@guideai.online.
01Is CleanReserve safe to use?
Yes. Every file is sorted into a safety tier, and only Tier 1 — the safest — is selected by default. You preview everything before cleaning, and Quarantine keeps files recoverable for seven days. Nothing is permanently deleted unless you choose the Delete method yourself.
02What does CleanReserve remove?
Tier 1 covers user caches, browser caches, system logs, Trash and download leftovers. Tier 2 adds larger developer and backup data such as Xcode DerivedData, iOS Simulator files, Time Machine snapshots and old iOS backups. Tier 3 covers advanced system caches, and Tier 4 is any folder you add yourself. Separate tools handle large files, duplicates, app leftovers, startup items and browser privacy.
03Why does it need Full Disk Access?
macOS protects folders such as /Library/Logs and parts of ~/Library. Without Full Disk Access, CleanReserve can only scan your user folders and misses a lot of reclaimable space. It only reads and reports — nothing changes until you confirm a clean.
04How does Quarantine work?
Quarantined files are moved to an encrypted folder (~/.CleanReserve/Quarantine, AES-GCM) and kept for seven days by default. Use Undo Last Clean to restore them. After the window, they're purged automatically.
05Why does macOS show a security warning?
CleanReserve is distributed directly rather than through the App Store, so macOS asks you to confirm the first launch. Open System Settings → Privacy & Security, find “CleanReserve was blocked” and click Open Anyway.
06Does the app collect or send my data?
No. All scanning and cleaning happens on your Mac. The app doesn't collect usage data and works fully offline. (This website uses Google Analytics — see the privacy policy.)
07Will it slow down my Mac?
No. CleanReserve only works when you start a scan or open one of its tools. It's a native SwiftUI app and doesn't run in the background.
08What if I remove something I needed?
With Quarantine, restore it within seven days using Undo Last Clean. With Trash, take it back out of the Trash before you empty it. Delete can't be undone, so review the preview carefully when you use it.
