Does NotchStar clipboard history need any permission
NotchStar’s Clipboard tool does not ask you for a permission. The code reads the standard Mac clipboard and nothing else, and it contains no request for Accessibility, Screen Recording, Input Monitoring or any other access.
What it reads
It reads the general clipboard, which is the same place Command C writes to. It does not watch your keystrokes, read your screen or look inside other apps. See how it detects copies.
What it does with it
The list stays in memory, up to 50 items, and is cleared when you quit. Nothing is written to disk or sent over the network. See privacy questions.
Which NotchStar tools do ask for permission
Not every tool is the same. The Calendar and Reminders tool asks for access through macOS the first time, as its feature page explains. The Mirror tool uses the camera. The Clipboard tool is separate from both.
Newer macOS versions
Apple may add prompts around how apps read the clipboard in some macOS versions. This page does not cover them. If your version shows a prompt about NotchStar and the clipboard, allow it, or the history may stay empty.
Limits
NotchStar cannot see a copy that an app marks as concealed. That is a privacy choice, not a missing permission. See password manager copies.
The tool is on the Clipboard feature page.
