Summary
Nikad Device Health Monitor does not collect, store, or transmit your personal data to us. There is no account, no sign-in, and no analytics or advertising tracking of any kind. Everything the app shows you — battery, memory, storage, CPU, network, and permission status — is read directly from macOS on your device and displayed to you there. It never leaves your Mac, with the two narrow exceptions described below.
What the app reads, and why
- Battery & thermal state — read via macOS's public power-source APIs, shown on the Battery screen only.
- Memory usage — read via macOS's virtual-memory statistics APIs.
- CPU load — read via macOS's processor-info APIs, per-core and overall.
- Storage & files — the Storage screen reads your disk's total/used/free capacity. The Disk Explore feature only looks inside a folder you explicitly choose via the standard macOS file picker (the app is sandboxed and cannot browse your files otherwise); duplicate/old/largest-file results stay on-device, and any deletions go to the Trash, never bypassing it.
- Wi-Fi & network — connection type, interface traffic counters, and (if you grant Location permission) the connected Wi-Fi network name. See "Location permission" below for why that specific permission is involved.
- App permissions audit — the Permissions screen reads the current authorization status (granted/denied/not requested) of system permission categories. It only checks status; it does not request access to anything the app doesn't otherwise use, and it cannot see what other apps do with their own permissions.
Location permission
macOS only reveals the name of the Wi-Fi network you're connected to (its SSID) to apps that have Location permission — this is an Apple platform requirement, not something this app chooses. Nikad Health Monitor does not read your GPS coordinates, does not track your location history, and does not use Location for anything other than unlocking that one piece of Wi-Fi information. You can deny or revoke this permission at any time in System Settings → Privacy & Security → Location Services; the app will simply grey out the network name instead.
The two network requests this app makes
The Network Diagnostics feature makes a small number of outbound requests directly from your Mac, only when you use that feature:
- api.ipify.org — to display your current public IP address.
- apple.com — a single lightweight request used to measure network latency ("ping").
These go straight from your device to those services to retrieve the result shown on screen. We (the developer) never see, log, or receive this traffic — it doesn't pass through any server we operate.
Data stored on your device
The app saves a small number of your own preferences locally on your Mac using Apple's standard UserDefaults storage — things like your chosen color scheme, whether you've completed onboarding, and your Disk Explore settings (scan mode, file-size/age thresholds). This data is private to the app, stored only on your device, and never transmitted anywhere.
Third parties & tracking
This app contains no analytics SDKs, no advertising frameworks, and no third-party trackers. The only outbound network calls are the two listed above, made directly to the named services for the sole purpose of displaying their result to you.
Children's privacy
This app is a general-purpose system utility not directed at children and does not knowingly collect information from anyone, regardless of age — because it does not collect personal information from any user.
Changes to this policy
If what the app accesses or how it behaves changes in a future update, this page will be updated accordingly before that update is released, with a revised "last updated" date above.
