Hey, as far as I know due to the nature of the engine and how it handles Android version of the game (it's basically a web-browser game in a wrapper) the saves are stored Chrome's (?) root folders and are not accessible in a normal way.
If you lost your saves, simply start the game via "New Game" and then select "Continue from a specific point in the story" - you can choose either a specific Day, or the moment when the story splits into character routes.
