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.

Klakk adds sound effects as you type in desktop applications. The current Windows installer and Mac direct edition are both 1.4.1. Here is a short Windows setup checklist, especially if the app opens but you hear nothing.

1. Check the PC and installer. Windows 10/11, 64-bit x64 and ARM64 are supported; 32-bit Windows is not. One installer selects the native build for your PC. The current Windows installer is unsigned. The official release includes checksums, but a matching checksum does not replace publisher signing; review security warnings and decide whether you trust the file before running it.

2. Enable playback, then choose a pack. In General, turn on Enable Klakk. In Audio, choose one of the 14 sound packs and set a comfortable volume. Type a sentence in Notepad to check the result.
