This app is a simple customer satisfaction survey for an car brand.
Every customer can answer to a satisfaction survey. Each survey are stored in a SQLLITE DB. This db is synchronzed with a remote DB by a button in the app's admin screen (because the app is not always connected).
The point is : If my client uninstal the app (for an update or whatever) , it's destroy the SQLLITE DB, and if the admin of the app doesn't synchronize it... The data for the past day are lost.
