ABOUT THIS APP
==============

This app both backs up and syncs content folders using USB drives.  It:

- Generally requires a removable USB drive for both backups and device syncs, as well as its PC versions for syncs to/from PCs.  Backups propagate changes to your USB drive.  Device syncs propagate changes first from source to USB, and then from USB to destination.

- Is provided freely on PCs, and for a modest fee on Android with a free trial version.  Use the links below to fetch free PC versions at quixotely.com, and full and trial Android versions at the Google Play store.

- Runs on Androids 8 and later, and on most Windows, macOS, and Linux PCs.  It has been verified on Androids 8 through 13 to date, and is expected to run on later Androids.  See the PC versions' download site for their version info.

- Does not advertise or collect information in any fashion, and changes your content only on your request with optional backups and rollbacks for syncs.  See below for more on this app's privacy policy, and the Help tab for more about using this app.

==========

Besides its own code, this app uses a number of open-source tools.  It:

- Is coded entirely in Python (python.org)

- Creates its GUI on all platforms with Kivy (kivy.org)

- Processes content with Mergeall (learning-python.com/mergeall)

See these components' websites for more details.


TRIAL VERSION
=============

Please use the app's free trial version for Android to verify that this app supports all your devices.  Although it has been tested and used widely, Android's variability makes it impossible to validate every phone and USB-drive combo, and PC support is tied to PC versions.

For more on version support, visit the User Guide's package docs by tapping its link in the Help tab.  The trial version can be opened a fixed number of times, so you can test-drive the app for your usage context and goals.
