did you delete the other version before downl0oading this one because that is how you would lose your data?

no, i download and play through the app and the data is stored in the appdata files on my computer and the data stays even if i delete from the app and would have to delete the files in the appdata to actually lose all data. I didn't do anything differently than what I always do which is to uninstall in the app and without leaving the page reinstall when updates occur because the apps tend to not actually update unless i do so at least on my side this and has worked with this game and many others with no problems related to data loss.
edit: After getting a few more updates from other games it appears that im losing game data from every game regardless of how I update them, whether i uninstall it first or just update it outright.
