how to backup tasks from S-planner to SD card?

[Jmclcsangels]

Does anyone know how to backup the tasks from S-Planner to an SD card? I've replaced my Franklin Day Planner with the Note 8. I use Google Calendar, so my events are already backed up. I just want to make sure my tasks are backed up too since that's a critical piece of the planner function for me.


Thanks.
