Hears every keystroke. Remembers none.
An app that listens to your keyboard should have to prove it can be trusted. Kachunk's answer is to let macOS do the enforcing.
What Kachunk can see
Kachunk uses a listen-only tap on keyboard events, gated behind the macOS Input Monitoring permission. It sees each key press just long enough to pick that key’s sound and stereo position, plays it, and forgets it — nothing is ever recorded or stored. It uses Input Monitoring only, not the broader Accessibility permission, and it never modifies or delays your keystrokes.
What macOS enforces
Kachunk runs in the App Sandbox with no network entitlement. That is not a promise — it is a technical guarantee: macOS itself prevents the app from making any network connection, so Kachunk can't phone home even in principle. No analytics, no accounts, no telemetry. Keystrokes are never recorded, stored, or transmitted.
Passwords
macOS suppresses keyboard events in password and other secure input fields, so Kachunk stays silent while you type passwords. Those keystrokes never reach the app at all.
What's stored
Only your settings — volume, chosen sound pack, and toggles — saved locally on your Mac. Nothing else is written, and nothing ever leaves your machine.
