You may export all the data to a text file on the SD card.
This serves as a backup and it allows you to transfer the tasks
to another device, either by connecting it to a PC or by sending it
with your email application. Optionally all finished taks can be
deleted after exporting them.
You may select the SD card or internal memory for storage of the text
file. Internal memory is only useful if you wish to temporarily backup
the data but don't have space on the SD card. If you want to send the
file by email, you must store it on the SD card.
The file name is preset, the extension .txt will be added automatically.
You may change the name if you want to create different backup files.

Send by Email

file as an attachment and your email client will be opened in order to
add the email address and send the email.
