Klakk on Mac: Input Monitoring, privacy and a first-sound checklist

Developer note from Levin, Klakk's developer. Prepared with AI assistance and checked against the current website-edition setup and privacy documentation.

This checklist covers the Mac website edition, 1.4.1 / build 23, on macOS 14 or later, for Apple silicon and Intel Macs. It is for the case where Klakk opens but you do not hear keyboard sounds in another app.

1. Start with the installed copy. Open the official DMG, drag Klakk to Applications and launch that copy. Avoid switching between the copy inside the DMG and the installed one. If you also have the App Store edition, check which edition you opened: it has its own release history and license.

2. Understand the permission before enabling it. Input Monitoring gives an app access to input while other apps are in use; macOS does not limit that permission to sound playback. Website Mac 1.4.1 processes key-down, key-up, modifier events and physical key codes locally to select sounds and recognize its shortcut. It does not upload typed text or raw keystrokes. It also sends usage/settings and licensing data; the privacy policy explains these communications. These are developer statements about this edition.

3. Enable Input Monitoring for Klakk. Open the installed app and follow its prompt, then use System Settings > Privacy & Security > Input Monitoring. Enable Klakk and quit/reopen it if macOS asks. Accessibility and Full Disk Access are not required for this website edition's keyboard playback. On a managed work or school Mac, ask the administrator if the setting is restricted.

4. Check playback and the actual output. Turn on Enable Klakk in General. In Audio, choose one of the 14 sound packs and a comfortable volume. Check Output Device: System Default follows the Mac's output, or select connected speakers/headphones explicitly. Confirm that both Klakk's and the Mac's volume are above zero. Type a sentence in Notes. Added audio does not change the noise or feel of your physical keys.

5. If it is still silent or very quiet, check Background Mode and the trial. Temporarily disable Audio > Background Mode while testing; it can reduce keyboard volume while designated meeting/media apps remain open. The website edition's three-day trial starts at first launch. Continued playback afterwards needs its own active license: US$4.49 once plus applicable checkout taxes. Windows and Mac App Store licenses are separate.
