Privacy Policy

Last updated 5 October 2026.

ScreenLock is a macOS utility that locks your keyboard, mouse and trackpad. It is built to do that and nothing else.

What ScreenLock collects

Nothing. ScreenLock does not collect, transmit or store any personal data. It has no analytics, no accounts, no advertising and no tracking, and it makes no network connections.

What stays on your Mac

Your settings (your chosen shortcut, dimming level, and the on/off switches) are saved locally on your Mac through the standard macOS preferences system. They never leave your device and are not readable by anyone else.

Keystrokes and input

To lock and unlock input, ScreenLock watches for your chosen shortcut and, while locked, blocks other keyboard and pointer events. It does not record, log, store or transmit anything you type or click. Input handling happens entirely on your Mac, in memory, for the moment it is needed.

Permissions

The version downloaded from this site asks for macOS Accessibility access. That permission is used solely to intercept input while the screen is locked. It is not used to read your screen or your keystrokes. The Mac App Store version runs without this permission.

This website

This site keeps anonymous visit statistics on our own server: the pages viewed, the site that linked you here, your approximate country (worked out from your IP address), your device and browser type, and clicks on the download buttons. A random id in your browser's storage tells a return visit from a new one, and IP addresses are deleted after 90 days. There are no third-party analytics, no advertising and no tracking cookies.

The demo on the home page remembers the shortcut and settings you try in your own browser's storage. They stay in your browser.
