# Does an automatic backup run when PrivacyNotes is closed?

On a computer, it runs while the app is open, and also while the window is closed to the tray. Turn that on in Settings > System > "Keep running in the tray". If a backup came due while the app was fully closed, it runs about a minute after you open it again.

A phone does not let an app run in the background for this, so on Android and iPhone the backup runs a few seconds after you open the app, when one is due. If you have not opened the app for a while, a phone notification tells you that a backup is overdue. In the browser, a backup runs only while PrivacyNotes is open in a tab.
