Your listening stays on your Mac.
Volume Shield is built to help you understand your own listening without collecting it. Here's exactly what that means.
Audio is analyzed in memory, then discarded
Volume Shield reads outgoing system audio only to compute numeric level statistics. Raw audio is never recorded, saved to disk, exported, or transmitted.
It doesn't collect what you're listening to
No song titles, artist or media metadata, application activity, or microphone content are collected. The app uses the Screen & System Audio Recording permission for outgoing audio and does not request microphone access.
Exposure history stays on your Mac
History is stored locally under the app's Application Support directory as aggregated numbers — level, duration, dose, confidence, and headphone context. It contains no audio buffers, media titles, or app names.
No account, no telemetry, no network
There is no sign-in, no analytics upload, no cloud sync, and no runtime networking. The shipped app contains no outbound-network code and no network entitlement.
You control export and deletion
Exporting or deleting your exposure history are explicit actions you take in the app, and neither one turns on networking. Deleting removes local history permanently.
A note on this page
This summary describes how the 0.9.1-beta.1 build behaves. It is a plain-language overview, not a contract. If Volume Shield ever adds an optional feature that changes any of the above — for example an opt-in diagnostic upload — that behavior will be disclosed clearly and turned off by default.
