Privacy Policy

Last updated: August 16, 2026

Nucleo ("the App") is a macOS utility for system monitoring and cleanup. This policy explains what data the App accesses and how it is used.

1. Data the App accesses

To do its job, Nucleo reads, on your Mac, locally:

• System sensor readings (CPU, GPU, memory, disk, temperature, fan speed, power draw, network throughput).
• File and folder metadata in locations you grant access to (caches, logs, Downloads, Trash, and other folders you select), used to identify what can be cleaned.
• A list of installed applications and their support files, used for the Applications and uninstall features.
• Startup items (launch agents/daemons), used for the Performance feature.

None of this data ever leaves your Mac. Nucleo does not operate a server, does not upload your files, file names, or system information anywhere, and does not build a profile of you or your device.

2. Full Disk Access

Some features request Full Disk Access, an macOS permission, to see caches and support files belonging to other applications. This permission is used solely to display and clean those files locally; it is never used to transmit data off your Mac.

3. Subscriptions and payment

Subscription purchases are processed entirely by Apple through StoreKit. Nucleo never sees or stores your payment details (card numbers, billing address). Apple may process your payment information according to its own privacy policy.

4. Analytics and tracking

Nucleo does not use third-party analytics, advertising, or tracking SDKs. No usage data is collected or shared with third parties.

5. Local logs

The App keeps a local, in-memory diagnostic log (visible in the Diagnostics screen) to help you troubleshoot issues. This log is not transmitted anywhere and is cleared when the App restarts.

6. Children's privacy

Nucleo is not directed at children and does not knowingly collect data from children.

7. Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with a revised "Last updated" date.
