The current version of Sonic Blitz does not include login with Facebook, Google Play, or Apple. 

This feature will be implemented in future releases, but for now, the only way to save your progress is to keep the app on your phone. Once this feature is available, you will be able to keep your progress since the start of your Sonic Blitz journey.

⚠️ Uninstalling Sonic Blitz will remove your progress, and you will have to start from scratch.
