TapNoiseInput Monitoring and Accessibility are separate macOS permissions. Input Monitoring allows observation of input across apps. Accessibility can enable inspection and control of interface elements and actions.
Match the permission to a feature
A typing sound utility needs to know a key was pressed while another app is active. A shortcut sheet may need to inspect the front app’s menus. A tool that sends a keyboard command has another control requirement.
The permission label is not a complete privacy policy. Read what the app actually processes, stores and sends, and check whether an optional feature can remain disabled.
TapNoise’s split
TapNoise requires Input Monitoring for its ordinary key feedback. Its optional shortcut sheet, Clean Mode and some knock actions use Accessibility.
Granting one does not automatically grant the other. If typing sounds work but an optional control does not, check the permission for that feature rather than repeatedly toggling the required typing permission.
Review access over time
Use System Settings › Privacy & Security to inspect the two lists. Revoke access for tools you no longer use, after disconnecting any integrations that need their normal removal flow.
Do not add Full Disk Access as a generic attempt to fix either permission. For a broader review, use the permissions checklist. For the typing-specific question, read Input Monitoring safety.
