Privacy Policy.
Cosmic Cleaner is private by design. This page explains what the app processes on your device, what it sends to us (nothing), and the rights you have.
The short version. Cosmic Cleaner does not collect, transmit, or sell any personal data. There are no accounts, no analytics, no advertising SDKs, no cloud sync. Everything the app does — scanning, previewing, deleting — happens on your device and stays there.
1. Who we are
Cosmic Cleaner (the “app”) is produced by the Cosmic Cleaner team (“we”, “us”). You can reach us at [email protected].
2. What data the app processes
To do its job — finding files and media that are safe to remove — the app reads metadata from your device. All of this processing happens locally. Nothing is transmitted off your device.
On macOS
- File system metadata inside developer and user cache locations you explicitly grant access to (for example Xcode DerivedData, Device Support, Simulators, Archives, CocoaPods, Gradle, Maven, Android Studio, JetBrains caches, Docker,
node_modules, Python virtual environments, user caches, iOS backups, and the Trash). - Running process information exposed by the operating system, used by the Memory Core panel to list top processes and trigger a RAM purge.
- Disk usage statistics reported by the system to show storage reclaimed.
On iOS
- Photo and video metadata via Apple’s PhotoKit framework, used to detect screenshots, large videos, large photos, selfies, Live Photos, old media, similar photos, and duplicate bursts.
- On-device image features computed with Apple’s Vision framework for similar-photo grouping and optical character recognition on screenshots. These features never leave your device.
- Storage statistics reported by the system to show space saved.
3. What we do not do
- We do not operate user accounts. There is nothing to sign up for.
- We do not use any analytics, crash-reporting, advertising, or tracking SDKs.
- We do not upload, back up, or sync your files, photos, videos, or any other content to any server.
- We do not sell or share personal data with third parties.
- We do not use your data to train machine-learning models.
4. Permissions the app asks for
The app only requests permissions that it visibly uses. You can revoke any of them from macOS or iOS System Settings at any time.
- Full Disk Access (macOS) — required to scan cache locations outside the user’s Library.
- Administrator password (macOS) — used only on demand for the Memory Core RAM purge, via a scoped sudoers rule that you install knowingly.
- Photo Library access (iOS) — required to read photo metadata and to delete items you choose.
5. Deletion is your action
Cosmic Cleaner never deletes anything silently. Items found during a scan are shown to you in a preview, and removal only happens after you explicitly confirm. On iOS, deletions go through the system Photos framework, which means they first move to the Recently Deleted album, where you can restore them for 30 days.
Always keep current backups. No cleaner — including this one — can undo a confirmed deletion outside the system’s own recovery window.
6. This website
The site you are reading is a static page. It does not set tracking cookies, does not include analytics, and does not embed third-party social widgets. The only network requests the page makes are for the Google Fonts stylesheet and font files, which are subject to Google’s own privacy terms. If you would prefer a fully self-hosted font setup, let us know.
7. Distribution platforms
When you download Cosmic Cleaner from the Mac App Store or the App Store, Apple collects purchase, installation, and crash data under its own privacy policy. We receive only the aggregated, anonymised reports Apple provides to all developers. We have no access to your Apple ID or payment details.
8. Children
Cosmic Cleaner is a general-purpose utility and is not directed at children under 13. We do not knowingly collect data from children.
9. Your rights
Because we do not store personal data about you, there is nothing for us to export, correct, or delete on our side. You remain in full control of the files and media on your own device. If you believe you have a privacy-related concern we have not addressed, contact us and we will respond promptly.
10. Changes to this policy
If we update this policy we will change the effective date at the top of the page and, where the change is material, announce it on the homepage. Older versions are preserved in this site’s Git history.
