Cuukit Screen Lid · last updated 2 August 2026
Cuukit Screen Lid collects nothing, sends nothing and stores nothing about you anywhere but your own Mac. There is no account, no analytics, no advertising, no crash reporting and no third-party service of any kind.
The app makes no network requests at all. It does not check for updates, does
not phone home, and has no server behind it. You can confirm this yourself
with Little Snitch, lsof -i, or by running it with Wi-Fi off — the
behaviour is identical.
scrypt hash of your PIN. The PIN itself is never written down, and the hash cannot be turned back into it.
Both live in a single file inside the app's own folder at
~/Library/Application Support/cuukit/. Delete that folder and every
trace of Cuukit's settings is gone.
macOS asks for Accessibility the first time you cover the screen. Cuukit uses it for exactly one purpose: to hold on to keyboard and trackpad input while the cover is up, so the cover cannot be dismissed and only the PIN keys get through. Nothing is recorded, logged or transmitted. Input events are dropped, not read.
The app has no content, no accounts and no data collection, so there is nothing for it to gather from anyone, of any age.
If this ever changes, the new policy will be posted on this page with a new date above, and the change will be described rather than quietly swapped in.
