Will deleting the app lead to loss of all data?

You lose nothing, but you gain previous time back lost by feeding the greed machine that makes this financial app;)

Account data is always stored on the servers.

However in order to get access to your account after reinstall you need to either link it to Google / Apple / Facebook account or write down your PlayerID which you will find on the settings screen. (Not your 9-digit ally code but a longer alphanumeric string)

That said, level 36 is trivial to get back to. You have barely scratched the surface of the game.

Depends.
If you have linked your account online, then yes, all your data is saved on the EA servers.
If you are playing a local only account, you data is stored on the device.

Why? ?

I have my game linked to Google since day one...i always link games to google.
Whenever i reisntall it keeps progress...and i have reinstalled over 10 times...for many reasons.
I actually left the game for several months due to work and time restrictions...when i resintalled, assuming i would have to start over...progress appeared automaticaly... :)
