Mactor Privacy Policy
Last updated
Overview
Mactor (“the App”) is a macOS menu bar system monitor. This policy explains what data the App accesses, what it does with that data, and what it does not do.
Short version: Mactor does not collect, store, transmit, or share any data. Everything stays on your device.
Data the App Reads
Mactor reads the following information from your local Mac to display system metrics:
| Metric | Data accessed | Purpose |
|---|---|---|
| CPU | Processor tick counts via host_processor_info() | Display CPU usage % and per-core breakdown |
| Memory | Virtual memory statistics via host_statistics64() | Display used / wired / compressed / free RAM and swap |
| Disk | Volume capacity and available bytes via URL.resourceValues | Display disk usage for mounted volumes |
| Network | Interface byte counters via getifaddrs() | Display download / upload speeds |
| Battery | Power source info via IOKit IOPSCopyPowerSourcesInfo() | Display charge %, status, and time remaining |
All of this data is read locally from macOS system APIs and is never written to disk, never sent to any server, and never shared with any third party.
Data the App Does NOT Collect
- No personal information (name, email, Apple ID, location)
- No device identifiers (UDID, serial number, advertising ID)
- No usage analytics or crash reports
- No keystrokes, clipboard contents, or screen recordings
- No data from other apps
- No network requests to external servers of any kind
Third-Party SDKs and Frameworks
Mactor has no third-party dependencies. It uses only Apple system frameworks (SwiftUI, AppKit, Charts, IOKit). There are no analytics SDKs, ad networks, or crash reporting libraries embedded in the App.
Data Storage
Mactor stores the following preferences locally on your device using macOS UserDefaults (@AppStorage):
- Which metrics to show in the menu bar (CPU, RAM, Disk, Network, Battery toggles)
- Preferred refresh interval
- Menu bar display mode (icon / values / both)
These preferences never leave your device.
Children's Privacy
Mactor does not collect any data from anyone, including children under 13.
Changes to This Policy
If this policy changes in a future version, the updated policy will be included with the new app version and the “Last updated” date above will be revised.
