You can easily backup all of your boards and lessons privately with Dropbox. This is especially recommended if you have invested a lot of time into creating your own boards. While we do our best to ensure that we never lose any data, creating a personal backup of all your Bitsboard boards in your own Dropbox account is even better.
To backup your boards with Dropbox, just press on the share button and then select the "Upload to Dropbox" option.
That's it! Now if you ever have to import your boards from Dropbox, just press on the "plus" button to add a new board and select the "Import from Dropbox" option.
