Hi, lanlynk, and welcome to the forums! It's great to see that you're enjoying VF2!

I completely understand why you are asking questions about the safety of your game progress on your tablet. Data can be lost on any electronic device when "bad things" happen (or even good things, like getting a new tablet), and it's important to be aware of how (and where) your data is stored, as well as how to get it back when needed.

The Android version of the game saves your progress with the same frequency that the Windows version does, but it doesn't display those reassuring messages that the game has been saved. The save files are stored on your tablet, but on Android devices, as with other mobile operating systems, they are stored in an area that is not accessible to users. Unfortunately, due to the built-in security protections in mobile device operating systems, the backup methods available for unaltered Android devices do not include app data. There are ways to back up app data, and you can do an Internet search for Android backup to learn more about this issue and what is possible.

We are exploring ways for the game to back up your game progress in more user-friendly ways, but it's too early to say exactly how and when we might implement that enhanced backup.
