SpongeWise Flashcard Clipper

Hi Loving it very much

Hi there.
I just started using it and I love how easy it is. Just one nagging question. If I am to use this in earnst, so for learning android programming , japanese, and mandarin languages, it is going to very quickly need some way to organise all that information , then there is the question of backup as well. What options as a user do I have to save and export and how may I maintain all that information.... will I have the option to export to my google drive? as a suggestion...
What are the limits parameters for each flashcard? just so I dont crash . How robust is the system if I am to rely on it for say learning japanese vocabulary.. already here we are talking about 10,000 words at the beginners level and with pictures....
