About the System Audio Recording permission

MacPulse Audio works by taking a live copy of the sound your Mac is playing — that's what macOS calls "System Audio Recording", and why it asks for your consent. The copy exists only inside the audio engine for the milliseconds it takes to filter it and hand it to your speakers. It is never written to disk, never analyzed for content, and never leaves your Mac.

About the Microphone permission

The optional Auto-align feature plays a short test pulse through each speaker and listens through your Mac's microphone to measure how long each output takes to reach you. The recording is used only to compute those timings, on-device, and is discarded immediately. MacPulse never touches the microphone outside a calibration you start yourself.

Settings stay local

Your output configuration — which devices are in the group, volumes, crossover frequency, delays — is stored in the app's local preferences on your Mac, nowhere else.

Crash reports

macOS shows a system dialog after a crash and asks if you want to share the report with Apple. MacPulse receives nothing from this flow. Sharing stays your choice.

Changes to this policy

Updates appear on this page with a new date at the top. The promise stays the same: MacPulse routes your audio and nothing else leaves your Mac.
