# How does Storage Studio know when I'm busy using my Mac?

It looks only at **how long it has been** since the last keyboard or trackpad input — the same idle time macOS itself keeps. It never sees what you type or click.

Two things use that signal:

- Background work shrinks while you're active and catches up once you step away.
- In **Smart** Quiet Hours, automatic actions wait while you've used the Mac within the time you set under **User active if input within last … minutes**.

You can adjust that time in Settings → Quiet Hours. See [Why does background work slow down when I use my Mac?](https://storagestudio.us/faq/performance-battery/why-does-storage-studio-ease-off-when-i-start-typing)
