How Nebula Protects Your Work

Reckless cleaner apps delete files you might still need. Nebula moves them safely and keeps them one click away.

STEP 01 Private & On-Device

Finds What You Don't Use

Scans safely in 10 seconds

Nebula checks when you actually last opened your files — not just when you saved them. Forgotten video clips, old downloads, and giant archives are grouped clearly so you see where your space went.

STEP 02 Double-Checked

Moves Safely, Never Deletes Work

Double-checks the copy before freeing space

Your files copy smoothly to your external drive or cloud. Nebula tests the new copy byte-by-byte to guarantee it's 100% complete and working before freeing any room on your Mac.

STEP 03 Always Accessible

Bring Anything Back in 1 Click

Instant one-click restore anytime

Need an old file back? Click once and it returns right to where it was. If you bring a file back, Nebula remembers that you're using it again and keeps it on your Mac.

Six Safety Rules That Keep You in Control

Nebula follows clear, non-negotiable safety rules so your active work, personal photos, and Mac health stay 100% safe.

RULE 01 Active

The Unused Files Rule

Files unopened for 2+ months

Files larger than 500 MB that you haven't opened in 60 days move to your external SSD. Older files (6 months+) can move to your home drive or cloud.

RULE 02 Active

Always-Free Breathing Room

Guarantees 20 GB free space

Keeps at least 20 GB of empty space so your Mac never slows down, freezes, or refuses to open apps. As soon as your Mac has breathing room, Nebula stops.

RULE 03 Active

Active Projects Stay Untouched

Shields your current work

Never touches projects you worked on recently or files you edit regularly. Only clears temporary junk and clutter that you no longer need.

RULE 04 Active

Photos Stay Fast & Protected

Browse photos smoothly

Keeps your photo browsing, search, and albums snappy on your Mac, while safely moving huge original videos and raw photo files to your backup storage.

RULE 05 Active

Double-Check Before Freeing Space

Zero data loss guarantee

Nebula reads every copied file from start to finish to confirm the backup is identical to your original. If anything doesn't match, your Mac's file stays safe.

RULE 06 Active

7-Day Safety Net

7-day grace period in your Trash

Freed files sit in your Mac's Trash for 7 days before anything is permanently removed. Change your mind? Put it right back with one click.

How Nebula Compares to the Alternatives

A clear, factual breakdown of doing it by hand, using popular Mac cleaners, and using Nebula.

Capability / Factor Manual Finder Cleanup Typical Mac Cleaners Nebula for Mac
Core Philosophy Tedious manual drag-and-drop or guessing in Finder Blindly deletes caches, logs, and files to claim "GB freed" Moves cold files to external/cloud; does not delete work
File Preservation High risk of accidental file loss or misplaced archives Permanent destruction of files and caches 100% preserved in external SSD, NAS, or Cloud mount
Integrity Verification None (silent Finder copy errors can corrupt files) None (files are deleted immediately) Double-checks every file byte-by-byte before freeing space
Restore Capability Requires manually hunting through backup disks Impossible (files are gone forever) One-click restore directly to original path
Developer & Photos Safety Manual sorting of project folders Known to break active projects and photo libraries Shields active projects; protects Photos library
Sandboxing & Permissions Standard user permissions Often demands root or full disk access Official Mac security sandbox; never asks for full access
Battery Impact Zero Heavy persistent menu-bar daemons and background agents Zero background daemons; runs strictly on-demand
Pricing Model Free (at the cost of hours of labor) $35 – $50 / year endless subscriptions $9.99 one-time purchase. Lifetime license.

Clear, Honest Answers to Common Questions

Have questions about data safety, external drives, or how Nebula differs from standard cleaner tools?

Yes, moving a Photos library to an external drive is completely safe when done properly. Nebula leaves your local thumbnail caches and albums intact for instant browsing, while safely moving heavy original videos and photo files without risking your Photos library.

Apple's Photos library stores your pictures inside a special package bundle. Moving it while Photos is open can sometimes cause permission hiccups. Nebula checks that Photos is resting, tests the copy to confirm every picture transferred perfectly, and preserves all your album organization.
