Beyond the information Apple provides to developers (provided you opt-in), FoodShiner uses no third-party analytics frameworks. FoodShiner does not log neither collect any personal information or usage data when using the application.
In TestFlight beta builds, FoodShiner may log crash reports to your device that you can explicitly choose to share (it will not leave your device otherwise). These reports do not contain any identifiable information. Simply put, your data is your data, and it will not be shared in any form to any third-parties.
FoodShiner stores all the data in a local database. If the user desires to have FoodShiner data synced across all the devices or want to share it with other persons on this case the user can choose to activate iCloud Sync. You can at any given time disable iCloud Sync from FoodShiner settings and even delete the data stored in the cloud.
FoodShiner uses specifically the CloudKit portion of iCloud, and all your data is stored in your own private CloudKit database located in Apple cloud servers. None of this data is stored on any servers controlled by FoodShiner. Furthermore, we have no access to any of your data in iCloud, as Apple does not give developers access to data in a user‘s private CloudKit database.
