Apologies if this has benn covered before but if so I cannot find it. My storage on the iPad is getting full and this is because two apps save all the data too, which I don't want. The apps are Dropbox and Eyefi Mobi. The only way I can see to delete the data is to delete the app, which I don't want to do as I use them very frequently. Another app, My Cloud, does not do this (just as well as it has more than a tB of data saved). Is there a way to keep the app but not have the data backed up to the IPad storage; back up to iCloud would be fine as I have space there, though it's not necessary.
