Your Mac. Your data.

The short version

Nuro Optimizer does not collect, transmit, or store any of your data anywhere outside your Mac. There is no telemetry, no analytics SDK, no crash reporter, no version-check ping, and no account system. The app has never made a network request from your machine to any of our servers — there is no server.

What the app reads on your Mac

To diagnose performance issues, the app reads system information that macOS already exposes to user-space tools — the same data you can see in Activity Monitor, System Settings, or Disk Utility. Specifically:

• Hardware specs, OS version, uptime, load averages
• Memory and swap statistics
• Disk capacity, S.M.A.R.T. status, APFS metadata
• Battery health (laptops) and thermal state
• Top processes by memory and CPU usage (names + PIDs only)
• Launch agents and daemons configured to run at startup
• Cache directory sizes (file content is never read)

This information stays on your machine. It is never uploaded anywhere.

Full Disk Access

macOS requires Full Disk Access for several of the analyzers above (notably scanning launch items in /Library/LaunchDaemons and reading SMC keys for thermal data). Full Disk Access lets the app read protected paths on your behalf — it does not give the app permission to send anything off-device. You can revoke it any time in System Settings → Privacy & Security → Full Disk Access.

Where data is stored locally

The app keeps a few small files in your home directory under ~/.macoptimize/:

• Benchmark snapshots — JSON files capturing system state before and after optimization runs, so you can see what changed.
• Action log — a plain-text record of which caches were cleaned and which startup items were toggled, so changes can be undone.

These files never leave your Mac. You can delete them at any time. ./reset-install.sh in the source tree wipes everything the app has touched.

Reversibility

Cache cleaning moves files to the Trash rather than permanently deleting them, so anything we shouldn't have touched can be recovered. Startup item changes are recorded transactionally and can be reverted from within the app.

The website

This site (optimizer.getsentium.com) is a static page hosted on GitHub Pages. It does not set cookies or run analytics scripts. GitHub may collect basic server-side request logs as part of operating their hosting infrastructure — that is outside our control and outside the app itself.

Distribution

The app is signed with an Apple Developer ID and notarized by Apple before every release. Apple validates the binary; macOS staples the notarization ticket to the app bundle so Gatekeeper can verify it offline. We use no third-party update servers, license servers, or telemetry endpoints.

Changes

If this policy ever changes, the new version will appear here with an updated date. The "no telemetry, no accounts" promise is a core product principle and is not going to change.
