If you want to clear your data on Beach Buggy Racing 2, you have two choices:
  1. You can RESET your game progress but keep your account. This will erase all of your game progress and purchase history and start you from the beginning, but you will keep your online account history. Also if you signed in with an email address and password you will keep those.
  2. You can DELETE your entire account. This will erase all of your game progress, purchase history, and online account information including your email and password (if you provided them). 
Again, please be aware that this action cannot be reversed or recovered.  Either way your entire game progress and history, including in-app purchases and prizes won, will be lost permanently.  Do not do this if you are unsure what it means or if you really want to do it.
 
To clear your data:
  1. Tap the "Settings" button in the upper left of the screen (with your player name)
  2. On the first tab, select the "Manage Account" button at the bottom.
  3. On the Manage Account screen, tap the "Delete Data" button.
  4. Choose if you want to Reset Game or Delete Everything
  5. Follow the prompts.
Again: Be warned this is a destructive act and you will not be able to recover any data after it is gone.
