Let me describe my scenario first.
I want to build an PhongeGap app for Android[4+] and IOS[5,6,7].
In which I want to store data around 3 to 4MB at max.
A user can use the app upto 2yrs of duration.
I read the PhoneGap Documentation on storage. According to the document WebSQL would be the sufficient implementation.
The followings are the factor why I am rethinking about WebSQL.
Will there be any support issue or compatibility issue in IOS,
Long term usage of the app so we should not compromise the data [WebSQL is Webstorage] &
Clearing the cache, Install/Uninstall of browser, clearing temp shouldn't cause the loss of data.
Suggest a Storage mechanism in my scenario.
