For Mac · macOS 13+ · Apple Silicon & Intel

Open the black box of “System Data”

macOS only tells you “System Data: 40 GB”. Clean system data shows you what's actually inside, item by item — with a deterministic traffic light that tells you what's safe to clean, and an AI that explains every item in your language.

The Stratigraphy: system data layers with green, yellow and red traffic lights

The Stratigraphy — your system data like a geological core sample. Each layer is a category, each color a verdict.

Every item gets a traffic light decided by deterministic rules — not by an AI that “thinks”.

Nothing is deleted directly: everything goes to the Trash, with Put Back guaranteed by our own manifest — macOS's is notoriously unreliable.

An AI button AI on every item explains what it is and why it has that color — in plain language, with sources, costs and timings out in the open.

01 THE STRATIGRAPHY

Measured on your disk. Not estimated.

An inventory of caches, logs, snapshots, dev builds and backups — every layer weighed in place, then colored by verdict. This is a real scan, from the app's demo inventory.

02 HOW IT WORKS

Three steps. No technical settings, no Terminal.

01

Scan

An inventory of caches, logs, snapshots, dev builds, backups and more — measured on your disk, not estimated.

02

Understand

Every item has a traffic light decided by deterministic rules and a clear explanation in your language, item by item. Optional: AI analysis.

03

Trash — and rethink

Nothing is deleted directly: everything goes to the Trash with Undo always available, via an internal manifest.

Item detail: red Do not touch traffic light, AI button, trash-first footer

Every item gets its verdict and its AI button. Red can't be cleaned — and nothing is ever deleted directly.

03 THE AI THAT EXPLAINS ✦

It explains. It never decides.

An AI button on every item tells you what that folder contains and why it has that color — in plain language, with cost and duration visible. One absolute rule: the traffic light is set by the rules, and the AI can never change it.

Safari's cache — why it's green

This folder is the browser's “storage room”: it keeps copies of pages you've visited so they reopen faster. It rebuilds itself whenever needed, so clearing it loses nothing important — you just get the space back.

  • Unverified assumption: on macOS betas this cache can grow larger than expected.

Batch analysis reviews the whole selection at once — 9 items in about 30 seconds.

04 SAFETY

One traffic light, zero anxiety.

The verdict isn't an artificial intelligence that “thinks”: it's a set of deterministic, transparent rules — verified item by item on your macOS version.

Safe to clean

Green

Caches and logs that regenerate on their own. Verified item by item on your macOS version.

Careful

Yellow

Useful but delicate: the app walks you through it step by step instead of blindly deleting.

Don't touch

Red

Snapshots, iPhone backups, system volumes: clearly explained and never offered for deletion — rejected at the code level.

05 PRINCIPLES

Built like an instrument, not a black box.

AI that explains, never decides

It tells you what the folder contains and why it has that color, in your language. The verdict always stays with the rules.

Trash-first, always

No direct deletion: everything goes to the Trash, with Put Back guaranteed by our own manifest.

Real undo

An internal undo manifest: restore to the original location even after emptying, with collision handling.

Total privacy

No telemetry, no analytics, no uploads. The optional AI only receives the item's name and path — never file contents.

The math of space

Why a “512 GB” drive shows 494, what purgeable space is, how much is really free: explained without jargon.

Three complete languages

Interface, explanations and knowledge base entirely in English, Italian and Spanish — AI analyses included.

06 FAQ

The things anyone would ask.

The red traffic light covers everything vital (snapshots, backups, system volumes) and is rejected at the code level: even if you select it, deletion won't start. Everything else goes to the Trash with Undo.
The purchase includes a cap of free AI analyses, counted for your license. When they run out, the app keeps working 100% — you can add your own API key to continue the AI analyses.
No. No telemetry, no uploads. The optional AI only receives the item's name and path with its verdict already decided — never file contents.
macOS 13 or later, Apple Silicon and Intel. The app asks for Full Disk Access to measure the real size of system data — with a step-by-step guide, and you can also use it without granting it.
