SsakSsak
A Mac cleaner that tells you why each item is safe to remove.
Caches, app leftovers and hidden big files —
swept away through the Trash.
If Mac cleaners made you nervous
Worried they'd delete the wrong thing, tired of scary warnings
Every item comes with a reason and a level: safe · careful · check first. Things that are slow to get back, like AI models and simulators, stay unchecked.
There is no direct delete. Permanent removal happens only when you press "Empty Trash". Every cleanup is kept in a history.
macOS files, Keychains, Mail, Messages, Photos libraries and iCloud folders are refused, whatever path leads there. Add your own folders · apps to Protected places and they're never touched.
The satisfying sweep
A broom sweeps, rows fly away, and the number fills up
Finds only what’s safe to delete, grouped for you
Safe · caution · check first — heavy re-downloads stay off by default
Everything goes via the Trash, and you can undo
Where your space goes
An answer to "why is System Data so big?"

What SsakSsak won't do
No red "1,234 problems found" warnings.
macOS already frees that cache when it needs to, so clearing it doesn't make your Mac faster.
Your scan results and the files you clean are never sent. The internet is used only for update and license checks, anonymous usage stats only if you turn them on (off by default) and feedback you send yourself.

FAQ
Does it only remove things that are safe?
By default it only checks what apps rebuild on their own: caches, logs and developer leftovers.
Files people made (downloads, screenshots, node_modules) and things that are slow to get back (AI models, simulators, backups) are shown but left unchecked.
macOS system files, Keychains, Mail, Messages, Photos libraries and iCloud folders never even show up in the list.
I cleaned up but my disk space didn't change
SsakSsak moves everything to the Trash.
Space comes back when you empty it — press Empty Trash on the finish screen or under Space map → System Data.
Can I get files back after emptying the Trash?
No. Files removed by emptying the Trash or Delete permanently can't be restored by SsakSsak, and SeoriArts has no obligation to recover deleted files (Terms, Article 8-2).
While items are still in the Trash, you can put them back from Cleanup History.
Check the list before cleaning, and keep a backup such as Time Machine for important files.
Which languages does the app speak?
English, Japanese, Simplified Chinese and Korean. It follows your Mac's system language, and you can change it in Settings → General → Language.
Which permissions does it need?
With Full Disk Access it can find app leftovers, the size of your Trash and Mail attachment copies.
It works without it, but it may miss things. It shows you how to turn it on the first time you open it.
What it reads never leaves your Mac.
How is it different from CleanMyMac?
It's a one-time purchase, every item shows a reason and a risk level, and there are no scary warnings or "free up RAM" buttons.
It doesn't do malware scans or app updates — it focuses on cleaning.
My code didn't arrive
Check your spam folder first.
If it isn't there, enter the email you paid with on Resend code.
What if I switch Macs?
Enter the same code on the new Mac.
You can remove the old one on Manage devices.
How do I remove SsakSsak?
SsakSsak → Settings → Remove SsakSsak at the bottom moves the app, its settings, history and log to the Trash and quits.
