How i can export the webstorage data to import into another device or simply to make a backup of the saved data?
Thanks!
You can extract the data and save it into a file or into a webhost from webstorage, but it seems like it defeats the purpose of webstorage, because webstorage is only your application's data, and you write there, why not write somewhere else in the first place instead?
