In the app you selected for this post, the data storage is local.
Honestly, I'm not really "on call" as your
personal research assistant and have already done a lot of work you can and should do yourself.
Hence, I'm closing this thread, as you seem very keen on finding ways to get others to do your work for you.
So far, you have shown very little ability or interest in doing any of your own basic research and work. Actually, why should I be installing and testing apps for you and doing the analysis and reporting back to you? My boss, MaxTheVeryLazyCat?
Please post back to this site when you are willing to do your own research and your own work and are not simply asking others to do all or most of your very basic work for you.
Cheers and Good Luck, MaxTheVeryLazyCat
