Is Full Disk Access safe?
What Karumac checks and what it does not

The safest way to judge this is by workflow, not by label alone

A cleanup app may need wider access so it can inspect caches, logs, app leftovers, and similar categories across your Mac. That does not automatically mean it is reading the contents of your personal files. The real signal is whether the app explains what it found and why it is recommending removal.

What Karumac actually checks

Karumac is designed around cleanup metadata rather than content analysis. In practical terms, that means it is looking for things like:

• where a file or folder lives
• how large it is
• whether it looks like cache, log, developer data, or app leftovers
• how to explain that category in plain language before removal

What it is not trying to read

The main anxiety people have is about photos, documents, passwords, messages, or private notes. Karumac is not built around opening and understanding those file contents to decide whether they should be removed. The product flow is explanation-first: surface the category, show the reason, let you decide.

If you feel unsure, start small

You do not need to delete anything on your first pass. A good first run is simply to review what appears, look at the reasons, and stop there. If the flow feels understandable, continue. If not, come back later. That is a valid use case, and Karumac is designed to support it.
