Your displays,
your settings.

On your Mac

Display names, brightness and volume levels, keyboard shortcuts and connection choices are stored on your Mac. Mac-Monitor talks to your monitors over DDC/CI and macOS display services; it does not read your screen contents, files or other apps.

Usage statistics

Mac-Monitor uses Google Analytics for Firebase to understand which controls work across monitors. It records when brightness or volume is adjusted (with the level) and when a display is reconnected, together with the monitor's vendor and product codes, which identify the model, not the individual unit. Firebase also collects standard app data such as an app-instance identifier, app and macOS versions, Mac model and an approximate region derived from your network address. Advertising features are off. Google processes this data under its own terms.

Update checks

The app uses Sparkle to request update information from MFLab's update host over HTTPS. Your network IP address and normal request headers may be visible to the hosting provider. Downloads and installation require your action.

Notices

Notices are listed in Notices & Support for everyone. If you turn on notifications for new notices, the app sends MFLab its Apple push token, a random installation identifier (stored only as a hash), the app version and your language, so a notice can be delivered once. Turning the option off stops these notifications.

Customer support

Customer support is optional. If you sign in with Apple to send a request, MFLab receives an Apple login identifier (not your name or email), the text of your requests and replies, screenshots you choose to attach, and the app and OS versions, so we can answer you. Monitor details are sent only when you type them. You can delete your support account at any time; see Customer Support Privacy.
