# Privacy and security: what MoreRoom reads and sends

> What MoreRoom reads on your Mac, the only three things it ever sends over the internet, how its rules are signed, and why it never runs downloaded code.

## In short

- Scans run entirely on your Mac. File names, paths and contents never leave it. No account, no analytics, no tracking.
- MoreRoom only goes online to activate and renew a Pro licence, to download its signed rule updates and to check for new versions.
- A rule update can only describe items; it can never make MoreRoom run something. Commands come from a fixed list built into the app.

## What MoreRoom reads

To build the map, MoreRoom reads the **names, sizes and dates** of files and folders — with Full Disk Access, including the protected ones. It doesn’t read what your documents say. A few features look at file contents, always on your Mac and only to compare or measure them:

- **Downloads Cleanup** compares files in Downloads to find those downloaded twice;
- **Quick Look** shows a preview when you ask for one.

## What MoreRoom sends — and only this

| When | To | What is sent |
|---|---|---|
| You activate Pro, then about once a week | `api.moreroom.app` | Your licence key (or the signed licence), an anonymous identifier of the Mac (a hash, not the serial number) and the Mac’s name |
| Once a day | `api.moreroom.app` | A request for the latest rule catalogue — nothing about you or your files |
| Once a day (if automatic updates are on) | `moreroom.app` | A request for the latest version of the app |

Buying Pro opens Stripe’s checkout **in your browser**; MoreRoom itself never sees your payment details. Everything else — scanning, rules, Storage Weather history, History of removals — stays on your Mac.

The full details are in our [privacy policy](https://moreroom.app/privacy).

## Signed rules, fixed commands

- The rule catalogue is **signed** by MoreRoom. A catalogue whose signature doesn’t match the key built into the app is ignored, and MoreRoom keeps the version it has.
- A rule can only **describe** an item: where it lives, its label, its explanation. When a rule says an item should be removed by its tool, it can only **name** a command from a fixed list built into the app — such as `xcrun simctl delete` or `brew cleanup`. Nothing from a downloaded rule is ever run.
- MoreRoom never runs scripts or programs found in your files or in downloaded data. When it [wakes up a project](https://moreroom.app/support/project-hibernation), it runs the tool’s standard install command, chosen from the same fixed list.
- App updates are signed too, and checked before they’re installed.

## Removing things safely

MoreRoom never removes anything on its own. Every removal is your choice, confirmed, and goes to the Trash first — except the few commands marked **Permanent**, which say so before they run. See [Remove items safely](https://moreroom.app/support/remove-items-undo).

## What MoreRoom keeps on your Mac

Its own data stays in your user account: the removal history and Storage Weather history (in `~/Library/Application Support/MoreRoom`), your settings, a small summary shared with the widget, and the Pro activation in your Keychain. [Remove MoreRoom completely](https://moreroom.app/support/reset-or-uninstall-moreroom) lists every file.
