Stop your computer from sleeping or Slack and Teams from marking you away while you’re still working.
Preventing sleep only keeps the screen on. Slack and Teams look at something else: how long it has been since you used the keyboard or mouse.
KeepGreen handles both separately. Prevent your computer from sleeping, reset the idle timer, or turn on both options at once.
By default it uses F15, which types nothing and leaves the cursor alone. If needed, switch to the 1 px movement, which moves the pointer and returns it to the same spot.
Choose from 15 minutes to 8 hours, or leave it on indefinitely. It turns itself off when time is up.
It uses barely any CPU while idle and keeps no windows open. It simply runs without demanding attention.
On macOS, you’ll find it in the menu bar; on Windows, inside the hidden-icons panel opened from the arrow next to the clock. It is available in six languages and can open automatically when you sign in.
An honest note: we don’t track you means KeepGreen creates no accounts, sends no data and needs no connection. It does not mean it is invisible. It is an ordinary application: it shows up in the process list and in software inventories, so on a computer managed by your employer, the IT team can see it like any other program you install.
KeepGreen is available for macOS and Windows. Each version is native, lightweight, and built for its operating system.

It is on the roadmap, but there is no release date yet. It needs to work properly across different desktops before it is published.
Why does the warning appear? KeepGreen is not yet notarized by Apple. For the same reason, macOS may ask you to grant Accessibility permission again after an update.
