[H2]About This App[/H2]

This app both backs up and syncs content folders using local drives usually connected by USB.  It:

— Uses a removable [i]drive[/i] for most roles, along with its PC [i]versions[/i] for syncs to or from PCs.  Backups propagate changes to your drive.  Syncs use a push/pull model that propagates changes first from a source to your drive and then from your drive to destinations.

— Is provided as [i]full[/i], [i]free[/i], and [i]ad-free[/i] programs on all supported devices.  Use the links below to fetch the Android app at the Google Play store and PC versions at quixotely.com.  A runnable source-code package is also available at quixotely.com.

— Runs on devices using [i]Androids[/i] 8 and later, as well as most PCs using [i]Windows[/i], [i]macOS[/i], or [i]Linux[/i].  It has been verified on Androids 8 through 16 to date and is expected to run on later Androids.  See the Downloads link below for PC version info.

— Does not collect [i]information[/i] of any kind and changes your [i]content[/i] only on your request with optional backups and rollbacks for syncs.  See ahead for this app's full privacy policy and open the Help tab to learn how to manage content with this app.
