Have no worries, if you linked your SUITSME account to your Apple ID (on iOS devices)/Facebook/Google account (on Android devices) your progress is saved. All you have to do is just login into your account using your credentials – (you can do it from the in-game settings which can be accessed on the left sidebar menu once you enter your profile by tapping your avatar on the top left corner).
Please note that there is no possibility to restore your account once you reset your device to factory settings and if you haven't linked it to any above-mentioned external accounts.
