The app

Gigabroom scans your disk to measure folders and match them against a list of known ones built into the app. The scan, the list and the cleaning all happen on your Mac. Nothing is moved or deleted until you click, and by default items go to the Trash.

The app does not have an account and does not show ads. The only statistics it shares are the anonymous usage statistics described below, and you can turn them off.

Explanations

Explanations are an optional subscription. When you ask Gigabroom to explain an item, the app sends our server:

• the item’s location, with your user name replaced by ~
• the item’s own name and whether it is a file or a folder
• for a folder, the names of up to 30 items directly inside it, and how many there are
• a rough size and age range, such as “1–5 GB” or “30–90 days”, never exact numbers
• the ID of the app that owns it, if known, and your app language

The contents of your files are never read or sent. The first time, Gigabroom shows this list and lets you see exactly what will be sent. Nothing is sent until you choose Explain.

Our server passes the request to the Claude Haiku model by Anthropic through OpenRouter. We ask OpenRouter to use only providers that do not collect or train on the data they receive.

The answer is stored on our server for 30 days so the next question about the same kind of folder is answered right away. It is stored under a one-way code made from the location, not the location itself.

Your license key

To activate a Mac, the app sends your license key to Polar together with a random-looking label derived from the Mac’s hardware ID. The label lets you see and free your Macs, and cannot be turned back into the hardware ID. The app checks the key with Polar from time to time.

When you use Explanations, the app sends the key to our server, which checks it with Polar. To keep this fast and to limit abuse, the server keeps a one-way code of the key, your Polar customer ID and your subscription status for up to an hour, and usage counters for up to a day. If someone repeatedly sends invalid keys, the server counts those attempts by IP address for a day.

Usage statistics

To learn which features people use and where the app gets stuck, Gigabroom sends anonymous usage statistics to PostHog, hosted in the EU.

• What is sent: events such as opening the app, starting and finishing a scan, opening a Clean Up group, asking for an explanation and whether it worked, opening the purchase window and which plan was chosen, activating a license, cleaning and whether items went to the Trash, emptying the Trash, using Put Back, opening the Disk Map, and turning statistics on or off. Each event includes the app and macOS version, the app language, the Mac’s processor type, whether you use the free version, a license or Explanations, and for scans whether Full Disk Access is on. Sizes, counts and durations are sent only as ranges, such as “1–5 GB”.
• What is never sent: paths, file or folder names, the names of your apps, your license key, your email address or any text you type.
• Who you are: events carry a random ID created on this Mac. It is not your email, your license key or your Mac’s hardware ID. There is no recording of your screen, no automatic capture of what you click and no personal profile. PostHog receives your IP address when events arrive, but our project is set to discard it, so it is not stored with the events.

Statistics are on by default. You can turn them off on the first screen of the app or at any time in Settings › Privacy: switch off Share anonymous usage data. Events are sent every few minutes and when you quit, never as the app opens, so you can switch statistics off on the first screen before anything leaves your Mac. When you switch it off, the app sends one last event saying statistics were turned off, then deletes the random ID and any events not yet sent, and sends nothing more. If you turn statistics back on, a new ID is created.
