Privacy Policy

Last updated: 8 May 2026

This privacy policy describes how the niacin macOS application (“niacin”, “the app”, “we”) handles information. It applies to the macOS app distributed via the Mac App Store and the source distribution on GitHub.

The short version

niacin does not collect, transmit, sell, share, or store any personal data. The app runs entirely on your Mac and makes no network requests. It has no analytics, no telemetry, no crash reporting, no advertising identifiers, and no accounts.

What the app does on your Mac

niacin wraps the macOS caffeinate command to prevent sleep, idle lock, and display sleep on demand. It reads your preferences from the standard macOS user defaults system, and — if your device is enrolled in MDM — reads managed preferences from /Library/Managed Preferences/com.oldsalt.niacin.plist. None of this information leaves your Mac.

Data we collect

None. The app makes no outbound network connections of any kind during normal operation.

Third-party services

The app does not embed or call any third-party SDKs, analytics platforms, advertising networks, or remote services.

App Store and platform data

If you install niacin from the Mac App Store, Apple may collect download and aggregate usage information independently of the app, governed by Apple’s own privacy policy. We do not receive any personally identifying information from Apple beyond anonymous, aggregated App Analytics provided by App Store Connect.

Managed deployments

When deployed through an MDM (such as JAMF, Mosyle, Kandji, or Intune), your IT administrator can configure the app’s behaviour through a managed preferences plist. The values they set are read by the app on your device. Your IT administrator may have separate logging or monitoring of MDM-managed devices governed by your organisation’s policies; that is independent of niacin and not controlled by us.

Children

niacin is a utility application not directed at children and does not knowingly collect any data from anyone, including children under 13.

Changes to this policy

If this policy ever changes — for example, if a future version of the app adds an optional feature that involves the network — the updated policy will be posted at this URL with a new “Last updated” date. Material changes will be highlighted in the app’s release notes on the Mac App Store and on GitHub.
