localStorage should not be backuped on iCloud

[vdias38]

What occurs

localstorage by default is backuped on cloud, see Cordova iOS Configuration. It can lead to an issue if localStorage of app is synced between multiples devices. Apple's Q&A explains only user data may be stored to the iCloud. Data that is needed for offline purposes may not be stored in the iCloud.

How to reproduce

See #35

Why it happens

More details about localStorage management on iOS:

localStorage in iOS is just a SQLite db file that is stored somewhere on the device.

Phonegap writes the localStorage.db file into the Documents directory for your app.

Specifically: Documents/Backups/localstorage.appdata.db

Since the Documents directory is specific for each app, it will be automatically saved to iCloud.

How to fix it

You can avoid it setting backupwebstorage preference to none on your confix.xml:

xml
<preference name="BackupWebStorage" value="none"/ >
