Your Mac's been piling up, huh?
Let's clean it together!

Compared with typical cleaners

Built to be understandable first,
not just packed with features

Instead of starting with an all-in-one dashboard, Karumac focuses on helping beginners understand what is being removed, why it is safe, and whether it can be restored.

Karumac

You understand the reason before removing anything

  • Explains what each file is before cleanup
  • Makes risk visible with Safe / Review / Caution
  • Moves to Trash first so you can restore later
  • Chat-based flow keeps the experience easy to follow
Typical cleaner

Powerful, but heavier to trust at first glance

  • You may need to interpret the cleanup list yourself
  • Names and categories alone can still feel risky
  • A feature-heavy dashboard can feel intimidating
  • Pricing and positioning can feel more advanced

Karumac is not trying to be the biggest suite yet. It is trying to be the cleanup app that feels easiest to trust on day one.

FAQ

Is Full Disk Access safe?

Yes. Full Disk Access is only used to check file sizes and types. Karumac never reads file contents or sends them externally. It's a standard macOS permission used by many utility apps.

Is my data sent anywhere?

Scan results are processed entirely on your Mac. Only when you use the AI chat feature are your messages and scan summaries sent to the AI server. File contents and passwords are never transmitted.

Can I cancel anytime?

Yes, cancel with one click anytime. You'll continue to have access until the end of your billing period, then you'll simply return to the free plan.

Which Macs are supported?

Any Mac running macOS 13 (Ventura) or later. Both Apple Silicon (M1/M2/M3/M4) and Intel Macs are fully supported.

What if I accidentally delete something?

Karumac moves files to Trash instead of permanently deleting them. Changed your mind? Just restore from Trash.

Is my personal data safe?

Karumac never reads file contents. It only checks "size" and "type." Your photos, documents, and passwords are never touched.

How is this different from CleanMyMac?

Karumac always explains why each file is safe to delete. What it is, why it can be removed, and whether it's recoverable. You'll never delete something without understanding it first.

Who is Karuma-shi?

A cute ghost girl from Fukuoka, Japan. She lives in your Mac with a vacuum cleaner and helps you clean up. She speaks in Hakata dialect. Her age is a secret.
