All of these other things can be ruled out because the problem only occurs on this one device. There is no dropbox sync or anything like that. The question is just whether I can reset this without erasing everything else in the process. It is clearly caching the list of folders and which feeds are in each folder, and the author forgot to implement a function to detect if folders have been removed from Google Reader. If a feed is removed, it is removed from the folder, but if I add the feed back to Google Reader, it appears under the old folders. If a folder is renamed on Google Reader, Byline shows both the old and new folders, showing the feeds under both. However, if a folder is deleted on Google Reader, it remains in Byline. The app downloads feed information from Google Reader, including which feeds are in which folders, and which folders there are. The app in question is Byline, an RSS reader. But if so, then there is no way to fix it short of wiping all data and not restoring any of it through iCloud/iTunes. My googling has suggested it is in the keychain, since that is the only place. In sum, the data must be stored somewhere that is not deleted when an app is deleted, and which is stored in iCloud independently of the app data for that app. So that is the mystery and why I am posting. For whatever data it was, I assumed that if I restored after not backing it up, it couldn't sneak back on to my device. It was the second thing I tried, after uninstalling the app to see if that would fix it, of course. I have also attempted the iCloud strategy. Indeed, the problem only exists on this one device. It is true that the popup when deleting an app claims that it will delete all the data, but this is apparently not so.īecause of the nature of the data (folder names on Google Reader, to be precise), it is unlikely for the data to be stored on a server hosted by the app company. I just want to delete the application settings in a way that does not require me to lose all my data and settings from everything else on my device. Is this the only possible place the app can store data permanently, in a way that is backed up to iCloud and does not delete when you uninstall the app?Īny suggestions are appreciated. I have read that keychain data functions this way, but my impression is that keychain stores things like passwords, rather than mundane application preferences. Is there somewhere that apps can store data, that is not part of the iCloud backup service and is not actually uninstalled when you delete the app? Erasing all contents and settings, and restoring from iCloud backup, where the app is *excluded* from the iCloud data Deleting the app normally, and then reinstalling (after syncing with iTunes, rebooting, etc) There must be a hidden cache of data that apps have, one which persists when uninstalling the app, and which is not stored on the app's application data. So if I delete the app, and then reinstall it, the data was never removed in the first place. For some reason, deleting the app does not actually delete the settings, and all of the broken data is conveniently preserved after deleting the app. I need to completely uninstall an app, because some of the settings or configuration of the app is bugged.
